Structured AI knowledge for GEO and programmatic SEO.

ContextHub is an independent reference directory that tracks 20 AI models across providers including OpenAI, Anthropic, Google, DeepSeek, Mistral AI, Meta, xAI, and Alibaba Cloud. Every model entry includes structured capability tags, SDK and API compatibility facts, source-backed documentation links, and freshness markers so developers and AI teams can evaluate options without navigating scattered provider documentation.

Each model record is maintained as static content through Astro Content Collections, verified against official provider documentation and GitHub sources. Fields such as pricing, context window size, and API style are explicitly version-tracked so high-change facts carry freshness dates rather than unchecked assumptions. The directory also generates 51 relationship edges between models, scenarios, and compatibility targets — powering programmatic comparison pages, GEO feeds (llms.txt, ai.txt, geo.json), and structured data exports without runtime databases or dynamic backends.

Use this directory to compare models by provider, best-fit use case, API compatibility, and source freshness. All pages are statically generated and deployable on Cloudflare Pages — no server-side rendering, no client JavaScript dependencies, and no third-party runtime search services.
