The SLM Opportunity: Data Flywheels, Edge Deployment, and the New AI Infrastructure Stack

Executive Summary

The path to capable small language models runs through efficiency, not scale. While frontier labs race toward trillion-parameter models, a parallel movement has proven that smaller, specialized models can match or exceed frontier performance for specific domains—at a fraction of the cost. The evidence is now overwhelming: DeepSeek R1, trained on constrained hardware with innovative techniques, matches OpenAI's o1 on reasoning benchmarks. Microsoft's Phi-4-reasoning outperforms models 20x its size. Meta's Llama 3.2 brings capable 1B and 3B models to edge devices.

This shift creates a massive market opportunity. Edge AI infrastructure is projected to grow from $20 billion to $270 billion by 2032. Within this, thousands of enterprises will deploy multiple specialized models—for clinical documentation, legal research, financial analysis, and real-time industrial control—creating demand for fine-tuning, deployment, and continuous optimization infrastructure.

Our thesis focuses on four durable sources of value creation:

Workflow-embedded applications with proprietary data flywheels: Verticalized enterprises have compelling reasons to adopt SLMs—cost, latency, privacy, and compounding data advantages. Research confirms that data quality outweighs quantity, and synthetic data techniques can amplify proprietary datasets. The persistent math/reasoning gap in generalist models creates structural opportunity for domain-specific specialization.
Enterprise packaging that captures value beyond commoditizing algorithms: Open-source SLMs commoditize the weights, but enterprises need more than algorithms—they need compliance, integration, on-device personalization, and privacy-preserving deployment. Winners build platforms, not just models.
Hardware-architecture co-design that creates durable differentiation: SLM performance depends critically on how architecture choices interact with specific hardware. Companies mastering NPU optimization, quantization-aware training, and inference scaling laws have defensible advantages that pure algorithm players cannot replicate.
Orchestration and edge-cloud collaboration as control plane: The future isn't SLM or LLM—it's intelligent routing between them. The orchestration layer that manages speculative decoding, cascade routing, and cost-quality tradeoffs becomes strategic infrastructure.

We hosted an SLM hackathon with AWS in November 2025 that validated these themes in practice—teams built functional prototypes on AWS Trainium demonstrating real-time reasoning, clinical documentation, and agentic systems in under 8 hours.

The SLM Movement: Key Milestones

The small language model movement has accelerated dramatically, with 2024-2025 representing a watershed moment. Several breakthroughs have fundamentally changed the calculus on model efficiency:

SLM Timeline — Figure 1: An overview of SLMs. Source: Lu et al, 2025.

DeepSeek R1 (January 2025): The Chinese lab demonstrated that reasoning capabilities can emerge through pure reinforcement learning, matching OpenAI o1 performance on math and coding benchmarks while training on constrained hardware (2,048 H800 GPUs vs. 16,000+ H100s for comparable U.S. models). The open-source release under MIT license validated that frontier capabilities no longer require frontier compute. DeepSeek's distilled models (7B-70B) set new benchmarks for their size classes.
Microsoft Phi-4 Series (December 2024 - May 2025): Phi-4 (14B parameters) outperformed GPT-4o-mini across MMLU, GPQA, and MATH benchmarks, proving that synthetic data curation and architectural innovation could compress frontier capabilities into deployable packages. The Phi-4-reasoning models released in 2025 achieve performance comparable to the full DeepSeek R1 (671B parameters) on AIME 2025, while running on NPUs in Copilot+ PCs.
Meta Llama 3.2 (September 2024): Meta's release of 1B and 3B text models optimized for edge devices, alongside 11B and 90B vision models, created the first production-ready on-device LLM family from a major lab. Quantized versions achieve 56% size reduction with 2-4x inference speedup, enabling smartphone deployment. Day-one optimization for Qualcomm, MediaTek, and Arm hardware established the on-device ecosystem.
Google Gemini Nano (2024): Google's system-level on-device LLM, integrated into Android's AICore service, demonstrated that platform providers would embed SLMs as infrastructure. Gemini Nano handles summarization, rewriting, and security tasks (scam detection in Chrome) entirely offline, with sub-100ms latency on Pixel devices.
Alibaba Qwen 3 Series (2025): The Qwen family expanded to eight models (0.6B to 235B), with SLMs featuring hybrid reasoning capabilities, 100+ language support, and Apache 2.0 licensing. Qwen's aggressive open-source strategy accelerated ecosystem development.

The common thread across these milestones: data quality, distillation, and architectural efficiency matter more than raw scale. This creates investment opportunity in companies that can operationalize these techniques for enterprise deployment.

Thesis 1: Workflow-Embedded Applications with Proprietary Data Flywheels

The strongest applications don't merely deploy SLMs—they own interaction context. Proprietary data creates a compounding flywheel, not just a static moat. While distillation techniques are commoditized through open-source tools, exclusive access to domain-specific data creates durable defensibility—particularly when that data compounds through continuous deployment.

The Flywheel Mechanism

Each customer deployment generates production data—queries, edge cases, failures—that feeds back into model retraining. A platform with 100 enterprise customers learning from production traffic accumulates institutional knowledge that new entrants cannot replicate. The model improves specifically for the contexts where it's deployed, creating switching costs beyond the initial integration.

Data Quality Over Quantity

Recent research has definitively established that data quality outweighs data quantity for SLM performance. The first comprehensive SLM survey (Lu et al., 2025) analyzed 70 open-source models and found that "the importance of data quality to the final SLM capability typically outweighs the data quantity and model architecture configurations." Two datasets—FineWeb-Edu and DCLM-baseline—achieved state-of-the-art results not through scale but through model-based filtering: using LLMs to score and filter training documents for educational value or quality signals.

This finding has profound implications for enterprise SLM strategies. A legal AI trained on 10,000 expertly-annotated contracts will outperform a model trained on millions of web-scraped legal documents—not because of domain specificity alone, but because expert annotation creates the quality signal that model-based filtering cannot replicate from web corpora. Frontier model providers (OpenAI, Anthropic, Google) excel at general capabilities but cannot easily acquire medical imaging datasets with radiologist annotations, industrial sensor data correlated with equipment failures, or clinical conversations with diagnosis outcomes.

Synthetic Data as Flywheel Amplifier

Breakthrough research in 2025 demonstrated that proprietary datasets can be expanded through LLM-assisted generation, accelerating flywheel dynamics. NVIDIA's Nemotron-CC pipeline (January 2025) showed that combining classifier ensembles with synthetic data rephrasing produced 6.3 trillion tokens—including 1.9 trillion synthetic tokens—achieving +5.6 MMLU improvement over prior state-of-the-art. The ReWire methodology demonstrated that "recycling" low-quality documents through LLM rewriting matches the performance of training on 2x more raw data.

For enterprises with proprietary datasets, this creates a multiplicative advantage: domain-specific data can be expanded through synthetic generation while maintaining quality, and the flywheel accelerates as production data feeds both direct retraining and synthetic expansion. Companies without initial data access cannot bootstrap this loop.

Why Enterprises Choose SLMs Over Frontier APIs

The case for domain-specific SLMs derives not primarily from capability but from constraints that frontier APIs cannot overcome:

Factor	SLM Advantage	Frontier API Limitation
Cost at scale	Lower self-hosted costs	High recurring API costs
Latency	On-device inference (<100ms)	API roundtrip (500-2000ms)
Data privacy	Full control	Third-party data transfer
Compliance	Faster approval (weeks)	Extended regulatory review (months)
Continuous learning	Learns from production data	Static between releases

Applications Enabled by SLMs

The Math and Reasoning Gap

While SLMs have made remarkable progress on commonsense reasoning and domain-specific tasks, a persistent capability gap remains in mathematical reasoning and complex logical analysis. The SLM survey found that from 2022-2024, model performance improved by 10.4% on commonsense reasoning but the gap with frontier models "remains significant in tasks requiring complex reasoning or logic, particularly in mathematics." This gap is attributed to the lack of high-quality open-source reasoning datasets.

This creates a structural opportunity for verticalized SLMs. Generic small models struggle with multi-step reasoning, but domain-specific fine-tuning on vertical data—where reasoning patterns are constrained and well-defined—can close this gap. A clinical decision support model doesn't need to solve arbitrary math problems; it needs to reason through diagnostic pathways that follow established medical logic. A legal analysis model doesn't need general theorem-proving; it needs to trace precedent chains within a defined corpus. The reasoning gap in generalist models is precisely where vertical specialization has the most headroom for differentiation.

Healthcare

Clinical documentation represents the clearest SLM success story. Abridge (raised ~$800M, valued at $5.3B) converts doctor-patient conversations into structured clinical notes in real-time, deployed across 150+ health systems including Mayo Clinic, Yale New Haven, and Johns Hopkins. The company's proprietary dataset of 1.5M+ medical encounters creates an insurmountable data advantage. Competitors Nabla and Ambience Healthcare are similarly embedded in clinical workflows, capturing interaction data that cannot be replicated.

Legal

Harvey (valued at $8B after multiple 2025 raises totaling ~$750M) has become the dominant legal AI platform, serving the majority of top 10 U.S. law firms and corporate legal departments at KKR and PwC. Harvey's value derives from embedding in lawyer workflows and accessing privileged legal work product that competitors cannot replicate. The legal AI market is bifurcating: Harvey for elite firms, EvenUp ($2B+ valuation) for plaintiff/personal injury, Casetext (acquired by Thomson Reuters) for legal research.

Financial Services

Fraud detection learning institution-specific transaction patterns, credit risk models with proprietary customer histories, and compliance monitoring represent core SLM use cases. The data sensitivity of financial services makes local deployment essential—institutions will not send transaction patterns to third-party APIs.

Industrial & Robotics

Quality control on factory floors without internet dependency, predictive maintenance learning equipment-specific failure patterns, and process optimization with proprietary sensor data require SLMs that run at the edge. Companies like Covariant (robotics manipulation), Bright Machines (factory automation), and Shield AI (autonomous systems) are building proprietary data moats through deployment.

Thesis 2: Enterprise Packaging Captures Value Beyond Algorithms

Model weights and algorithms are commoditizing rapidly. Llama 3, Mistral, Qwen, and Phi-4 are free, open-source, and improving quarterly. Any model released today will be obsolete within a year. Companies whose only asset is a fine-tuned open-source model lack defensible businesses.

The value derives from making models production-ready for enterprises and maintaining them over time. This follows the Linux vs. Red Hat pattern: the kernel is free, but packaging it with enterprise support, security updates, compliance certifications, and infrastructure integration built a multi-billion-dollar business.

Enterprise Requirements

Enterprises will not deploy open-source distillation scripts directly. The gap between technical capability and production readiness includes:

Compliance Infrastructure: SOC2, HIPAA, ISO certifications; audit trails; data lineage tracking; access controls
Integration Requirements: SSO; security monitoring (Splunk, Datadog); model registries; CI/CD pipelines
Operational Necessities: SLAs with guaranteed uptime; support contracts; rollback capabilities; A/B testing

Open-source tools provide 80% of technical capability but 0% of enterprise requirements. Companies capture value by solving the painful 20%.

The Business Model: Land and Expand

Initial model development serves as the 'land' motion—demonstrating value and establishing relationships. Customers might pay $50K-$100K for initial fine-tuning and optimization. But defensible revenue comes from the 'expand' motion: continuous monitoring as data distributions drift, retraining as edge cases emerge, A/B testing new approaches, and managing multiple model versions simultaneously. This creates recurring revenue ($10K-$50K monthly) rather than one-time project fees.

The Consulting Trap

Model specialization risks devolving into low-margin professional services if every customer requires bespoke integration work. A clear indicator: can companies onboard new customers without assigning dedicated engineers? Revenue scaling linearly with headcount signals services economics (30-50% gross margins) rather than software economics (70%+). Trajectory matters more than current state—companies doing consultative work with their first 10 customers while building automation for the next 100 can evolve into software businesses.

On-Device Personalization as Enterprise Requirement

Enterprises increasingly require models that learn from user and customer data without sending it to the cloud—a capability they will pay for, not build themselves. The technical challenge is substantial: fine-tuning even a 1.3B-parameter model with LoRA typically requires over 14.5 GB of GPU memory, exceeding the 4-12 GB available on most mobile devices.

Research in 2025 has produced promising solutions that SLM providers can operationalize. Fed MobiLLM (August 2025) introduced server-assisted side-tuning that decouples gradient computation from mobile devices: each device runs only forward propagation and uploads activations, while a server handles backpropagation asynchronously—achieving 5.1x faster convergence than prior approaches. PF2LoRA, presented at ICLR 2025, proposed two-level LoRA adaptation where a first level learns a common adapter across all clients while a second level enables individual personalization with minimal additional memory overhead.

These techniques remain research-stage, but enterprises are already expressing demand. Financial institutions want fraud models that learn institution-specific transaction patterns. Healthcare systems want clinical assistants that adapt to individual physician documentation styles. Consumer applications want personalization without centralizing user data. Open-source tools provide none of this—the gap between academic research and production deployment is precisely where SLM providers capture value.

Privacy and Edge Deployment as Structural Differentiator

For regulated industries, on-device and on-premise deployment isn't a feature preference—it's a structural requirement driven by compliance, data sovereignty, and liability concerns. Healthcare organizations face HIPAA constraints on patient data transmission. Financial institutions operate under data residency requirements. Legal departments cannot risk privileged work product traversing third-party infrastructure.

These constraints create structural demand for SLM providers who solve the full deployment stack. Google's Gboard demonstrated planetary-scale federated learning with 10-20% accuracy improvements while maintaining differential privacy guarantees—but enterprises cannot replicate this infrastructure internally. Our hackathon highlighted that data sanitization for edge deployment is a genuine pain point without mature solutions.

Open-source weights solve none of these problems. Compliance certifications, audit trails, data lineage tracking, and privacy-preserving learning infrastructure require sustained engineering investment that enterprises will not undertake for non-core capabilities. SLM providers who package these requirements—not just the model weights—capture the value.

Thesis 3: Hardware-Architecture Co-Design Creates Durable Differentiation

SLM performance isn't just about the weights—it's about how architecture choices interact with specific hardware. The comprehensive SLM survey found that models with similar parameter counts can have dramatically different runtime performance: Qwen1.5-0.5B has 25% more parameters than Qwen2-0.5B but runs 32% faster on the same hardware. Companies that master architecture-hardware co-design have defensible advantages that pure algorithm players cannot replicate.

Architecture Trends Define Deployment Viability

The SLM landscape has converged on specific architectural choices optimized for edge deployment. From 2022-2024, the survey documented clear transitions: Multi-Head Attention (MHA) gave way to Group-Query Attention (GQA), which reduces KV-cache memory requirements. Standard feed-forward networks were replaced by Gated FFN with SiLU activation, which NPUs handle more efficiently. LayerNorm transitioned to RMSNorm for computational simplicity. Vocabulary sizes expanded beyond 50K tokens to improve multilingual capability—but this creates memory tradeoffs, as Bloom's 250K vocabulary causes 3.5x larger compute buffers than OpenELM's 32K vocabulary.

These aren't arbitrary choices—they reflect hardware constraints. GQA reduces memory bandwidth requirements critical for memory-bound edge inference. SiLU activation aligns with NPU instruction sets. The architectural decisions made during pre-training constrain deployment options permanently; a model architected for cloud GPUs cannot be efficiently deployed to mobile NPUs through post-hoc optimization alone.

Quantization Is Not One-Size-Fits-All

The survey's runtime benchmarks revealed that 4-bit quantization hits a sweet spot—but not because lower precision is always better. 3-bit quantization underperforms 4-bit despite higher compression because irregular bit-widths lack hardware optimization support and incur alignment overhead. 5-bit and 6-bit quantization often produce inference latency comparable to or exceeding 8-bit, despite higher compression, because they too lack native hardware support.

This finding has investment implications: companies offering "quantization as a service" without hardware-specific optimization provide commodity value. Defensible positions come from deep integration with specific silicon—understanding which quantization schemes a Qualcomm Hexagon NPU handles natively versus which require costly software emulation.

Hardware Is Catching Up to SLM Requirements

Silicon vendors are now designing specifically for SLM workloads. Google's Coral NPU (2025) is an AI-first architecture co-designed with DeepMind, collaborating with the Gemma team to optimize for small transformer models—positioning it as the first open, standards-based NPU designed for LLMs on wearables. MediaTek's Dimensity 9400+ NPU supports speculative decoding natively (20% performance boost), handles DeepSeek-R1-Distill models with 1.5-bit to 8-bit precision, and implements Mixture-of-Experts and Multi-Head Latent Attention in silicon.

Qualcomm's Hexagon NPU evolution—fusing scalar, vector, and tensor accelerators with dedicated power delivery—demonstrates that mobile silicon is becoming SLM-aware. The Snapdragon 8 Gen 3 delivers 98% faster AI performance with 40% improved efficiency specifically for sustained inference workloads.

Inference Scaling Laws Change the Calculus

Emerging research on inference scaling laws suggests that the optimal deployment strategy may not be "use the largest model that fits." Work published at ICLR 2025 demonstrated that using a smaller model and generating more tokens often outperforms using a larger model at fixed compute budget—a 7B model outperforms a 34B model until 128 solutions are sampled from the larger model.

The "Densing Law" published in Nature Machine Intelligence (November 2025) found that capability density—capability per parameter—doubles approximately every 3.5 months. This means equivalent model performance can be achieved with exponentially fewer parameters over time, but only if deployment infrastructure can exploit this efficiency through techniques like test-time compute scaling, speculative decoding, and adaptive inference.

Companies building hardware-aware optimization layers—architecture search for specific deployment targets, quantization-aware training pipelines, NPU-specific kernel optimization—capture this value. Generic serving infrastructure cannot.

Key Players: Hardware-Architecture Optimization

Qualcomm AI Engine	Mobile NPU silicon + software stack	Hexagon NPU powers on-device inference for Android ecosystem
MediaTek NeuroPilot	Mobile SoC with NPU	Dimensity series with native MoE, speculative decoding support

Apple Neural Engine	Integrated NPU in Apple Silicon	Powers on-device models in iOS; proprietary but sets ecosystem expectations

Thesis 4: Orchestration and Edge-Cloud Collaboration as Control Plane

The future isn't SLM or LLM—it's intelligent routing between them. The capability gap between edge-deployed SLMs and cloud-hosted frontier models will persist; SLMs will not match GPT-5 or Claude 4 on general reasoning. But most queries don't require frontier capabilities. The orchestration layer that decides when to use edge versus cloud, manages speculative decoding across the boundary, and optimizes for latency/cost/quality tradeoffs becomes the platform control plane.

Why Serving Commoditizes But Routing Doesn't

Raw inference serving has commoditized through open source. vLLM introduced PagedAttention for memory management, doubling throughput for long sequences—it now serves as the de facto backend for most deployments. SGLang optimizes for structured generation. llama.cpp enables inference on consumer hardware. These tools are free, improving rapidly, and increasingly interchangeable.

But serving solves only single-device inference. Harder problems remain unsolved by open source:

Query classification: Determining in real-time whether a query requires edge SLM, cloud SLM, or frontier LLM capabilities—before incurring inference cost
Speculative coordination: Managing draft-verify loops between edge and cloud models efficiently across network boundaries
Fleet synchronization: Updating models across thousands of devices without downtime, version conflicts, or distribution drift
Cost-quality optimization: Dynamically trading off response quality against latency and compute cost based on application requirements

The Edge-Cloud Collaboration Taxonomy

Research in 2025 has formalized how SLMs and LLMs can collaborate. A comprehensive survey (July 2025) categorized approaches into three patterns:

Cascade Routing: A lightweight router—often a small classifier or uncertainty estimator—determines whether to process a query entirely on edge SLM or escalate to cloud LLM. Simple queries (typically 80% of volume) run on cheap edge devices; complex queries (20%) escalate. Blended cost drops 4x+ compared to cloud-only deployment.

Speculative Decoding: The edge SLM rapidly generates draft tokens that a cloud LLM verifies in bulk, accepting correct tokens and correcting errors. This preserves the output distribution of the stronger model while amortizing its cost across multiple tokens per verification call.

Mixture-Based Collaboration: Hybrid approaches that combine assignment and division—using SLM outputs to guide LLM generation, or routing different parts of a complex query to different models based on subtask requirements.

2025 Research Breakthroughs

Several technical advances have made edge-cloud collaboration practical:

Distributed Split Speculative Decoding (DSSD), presented at ICML 2025, partitions the verification phase between device and edge server. This replaces uplink transmission of full vocabulary distributions with a single downlink transmission—significantly reducing communication latency while maintaining inference quality.

Quantize-Sample-and-Verify (October 2025) introduced adaptive mechanisms that dynamically adjust draft token length and quantization precision based on semantic uncertainty and channel conditions. This enables speculative decoding over wireless networks with variable bandwidth.

Uncertainty-aware hybrid inference uses lightweight signals—epistemic uncertainty from temperature perturbations, token importance from attention statistics—to decide which tokens require cloud verification. Tokens are uploaded only when both uncertain and important, reducing unnecessary LLM queries by filtering confident predictions locally.

The Capability Gap Is Structural

These collaboration patterns exist because the SLM-LLM capability gap is structural, not temporary. Frontier models will continue advancing; SLMs will always trail on general reasoning. But this is feature, not bug, for orchestration infrastructure: the gap creates permanent demand for intelligent routing.

Google's Gboard and SwiftKey already implement this pattern—local SLMs handle speech recognition and text prediction, escalating to cloud only for complex understanding. Industrial monitoring systems use edge SLMs for real-time anomaly detection, escalating to cloud LLMs only when potential risks are detected. These deployments validate that hybrid architectures work at scale.

The AWS Trainium Opportunity

AWS's custom silicon strategy creates both competitive pressure and partnership opportunity for orchestration. Trainium2 chips (announced December 2024; came online in late 2025) deliver 30-40% better price-performance than GPU instances, with Project Rainier deploying 500,000 Trainium2 chips for Anthropic—scaling to 1 million by end 2025. Trainium3 (expected late 2025) promises 2x performance and 40% better energy efficiency.

For companies building orchestration infrastructure, Trainium creates opportunity: AWS Neuron SDK supports PyTorch and 100,000+ Hugging Face models, enabling cost-effective training and inference. Orchestration platforms that span Trainium (cloud), Graviton (edge servers), and third-party NPUs (mobile) become the unifying control plane across heterogeneous silicon—precisely the position that captures platform value.

Field Notes: AGI House x AWS SLM Hackathon

On November 8, 2025, we co-hosted an SLM Build Day with AWS in New York City. The event brought together builders, researchers, and engineers to work directly with AWS Trainium chips and explore model optimization, fine-tuning workflows, and reasoning with small language models. In under 8 hours, teams built and demoed functional SLM prototypes capable of real-time reasoning—validating our thesis in practice.

What We Observed

Healthcare applications dominated: Multiple teams built clinical documentation and medical AI tools, including systems for mental health practitioners, multi-agent clinical safety analysis, FHIR-compliant data conversion, and FDA drug label processing. The demand for HIPAA-compliant, locally-deployed clinical AI is clearly strong.
Agentic architectures emerged: Teams demonstrated scaling embodied AI from single agents to multi-agent systems using SLMs for real-time spatial reasoning—achieving significant cost reductions over cloud-based approaches. This validates the hybrid routing thesis.
Trainium proved production-ready: Teams successfully fine-tuned Qwen models on Trainium, deployed inference endpoints, and achieved real-time performance. Migration tooling projects addressed genuine pain points in the ecosystem.
Privacy-first design is non-negotiable: Projects for sensitive data sanitization and offline-capable systems highlighted that data privacy isn't a feature—it's a fundamental requirement for enterprise deployment.

Emerging Opportunities

Fleet management systems: Orchestrating thousands of edge devices as unified infrastructure
Confidence-aware routing: Integrating evaluation signals into deployment decisions
'Model appliances': Bundling optimized weights with compliance enforcement for regulated verticals
Outcome-based pricing: Tied to domain KPIs (contracts reviewed, diagnoses confirmed)
Personal memory stores: Privacy-preserving, persistent context learning individual preferences

Conclusion

The SLM market is bifurcating: frontier APIs win generic tasks, while specialized SLMs win domain-specific applications where structural constraints favor local deployment. We are investing in companies that demonstrate strength across our four theses:

Proprietary data flywheels in regulated verticals: Companies with exclusive access to high-quality domain data that compounds through deployment, amplified by synthetic data generation techniques.
Enterprise packaging that solves the painful 20%: Platforms that deliver compliance, integration, on-device personalization, and privacy-preserving deployment—not just fine-tuned weights.
Hardware-architecture co-design expertise: Teams that understand how architectural choices (GQA, quantization schemes, vocabulary size) interact with specific silicon targets, and can exploit inference scaling laws.
Orchestration infrastructure for edge-cloud collaboration: Control planes that intelligently route between SLMs and LLMs, manage speculative decoding across network boundaries, and optimize cost-quality tradeoffs dynamically.

The evidence from DeepSeek, Phi-4, Llama 3.2, academic research on inference scaling, and our hackathon participants is clear: efficient, specialized models will power the next generation of AI applications. The opportunity is substantial—tens of billions in addressable market for model development and deployment infrastructure. We're actively seeking founders building in this space.
