Key is account_id:token info
Cloudflare Workers AI authenticates with a combined credential in the form "account_id:token", not a bare token.
Needs token room info
This route can spend hidden reasoning tokens before visible output. Avoid tiny max_tokens values or the request can finish by length with empty content.

Anonymous tier is 2 req/min warning
OVH AI Endpoints anonymous mode is documented at 2 req/min per IP per model (observed even stricter across models). The 400 req/min authenticated tier requires a Public Cloud project with a payment method, so the catalog ships the keyless path. Treat as a breadth/fallback tier, not a throughput tier.
No API key required info
Routes anonymously — the catalog ships a keyless sentinel row and calls work with no account or key.
Needs token room info
Some free routes spend hidden reasoning tokens before visible output. Avoid tiny max_tokens values or requests can finish by length with empty content.

Recurring free, 40 RPM, eval-only ToS info
NVIDIA NIM replaced its depleting trial credits with a recurring per-account rate limit (40 RPM default, varies by model), verified June 2026. The trial ToS still scopes usage to evaluation/prototyping, not production.

Shared daily free requests info
CLōD grants 100 requests per day across eligible free models, automatically replenished, with no card required. This is daily, not monthly, and not a separate grant per model. Use the exact friendly model IDs including spaces. Only four routes returned consistent upstream identities in live tests; Llama and Trinity aliases that substituted Gemma are excluded. Matching response IDs do not independently verify the served weights. Context and tool support are not claimed without provider-specific evidence.

Free plan is 1 request per minute info
Api.Airforce Free grants 1,000 requests per day at 1 request per minute per account with per-model token caps and no card. The 21 listed routes returned matching model IDs on September 15. kimi-k2.7-code requires a paid plan; gpt-oss-120b, Mistral Large and Mistral Medium returned 503 and are excluded. Most routes are proxied Mistral free-plan models; treat them as sharing that upstream capacity.

FreeLLMAPI is a self-hosted router you run yourself. Install it, paste in your free Groq key, and openai/gpt-oss-20b answers on an OpenAI-compatible endpoint at http://localhost:3001/v1. No credit card, no hosted middleman: your prompts and your provider keys never leave your machine.

print(resp.choices[0].message.content)The router answers on /v1/chat/completions and every other OpenAI surface, plus the Anthropic Messages API, so existing clients need only a new base_url. Swap the model id for auto and the router picks the best free model that is still under its limits. Full reference: docs/api.md.
