Signal Analysis

Five Waves Reshaping AI

The structural shifts defining the open-source AI landscape through 2028.

Small Models Dominate the Edge

Sub-8B parameter models now rival GPT-4 on specialist tasks. IBM Granite 4 (1B) achieves 70% accuracy and runs on any consumer device. The era of "one giant model for everything" is ending — domain-specialized small models are cheaper, faster, and more controllable.

INFRASTRUCTURE SHIFT

Agentic AI & RAG Become Standard

RAG remains the #1 enterprise customization pattern. AI agents with tool-calling are replacing entire workflow automation stacks. Multi-agent orchestration frameworks (like Oceanic's platform) are now production-grade, enabling complex autonomous workflows at scale.

WORKFLOW TRANSFORMATION

Inference Economics Becomes a Board-Level Metric

Token spend is now a CFO concern. Enterprises are building internal "inference budgets" and treating model choice like vendor procurement — measured, negotiated, and optimized.

ENTERPRISE SIGNAL

China-Led Open Ecosystem Rises

Qwen3 and DeepSeek now dominate open model adoption charts. Total open model adoption shifted from US-dominant to China-dominant in 2025. This geopolitical dimension of AI is reshaping enterprise sourcing strategies and creating new sovereignty considerations.

GEOPOLITICAL SIGNAL

Multimodal & Domain-Specific Models Proliferate

Vision-language, code-optimized, and vertical-specific variants (Med-Qwen, Fin-R1) are creating a long tail of purpose-built AI. Fine-tuning via LoRA adapters means organizations can build proprietary AI moats without sharing their data with model providers.
