What this is,
and how to bring your own key.
The Frontier Model Index is an independent, automatically-updated tracker of frontier and Chinese AI models — benchmarks, user reports, a release timeline, a neutral op-ed, a model roadmap, and deep dives on cyber capability, China's catch-up, compute, and military AI.
How it stays current
A scheduled agent (AWS Lambda / GitHub Actions / cron — no Firebase CLI) runs daily: it searches the web with Tavily, synthesizes a structured dataset with DeepSeek-V4.1-pro, and writes it to Cloud Firestore. These pages read that document live, with a baked snapshot as fallback. The neutral op-ed regenerates at least weekly. See the methodology & system prompts (on this page and in the open repo) and live status.
DeepSeek's two API surfaces
DeepSeek serves the same models behind two compatible endpoints. The updater calls the OpenAI format first and auto-switches to the Anthropic format if needed.
The OpenAI-format endpoint speaks the chat/completions API — drop-in for the OpenAI SDK by setting baseURL. The Anthropic-format endpoint speaks the /v1/messages API — drop-in for the Anthropic SDK. Same models, same key; pick whichever SDK your code already uses. This site auto-switches between them for resilience.
Key vault & comparison playground
Save your own provider keys to unlock the side-by-side model comparison. Keys are stored only in this browser (localStorage) and never sent to us — we have no server. Delete any time to fall back to defaults.
The playground runs your prompt across 2–3 selected models using these keys. Some providers block browser calls (CORS); DeepSeek and Gemini generally work. Keys never leave your device except in the direct request to each provider you run.
