Models and rates
One price sheet for every model.
Every model below runs on the same API key and the same prepaid balance. Rates are in US dollars per one million tokens, and they are exactly what the usage log deducts.

$10 credit + 100 requests / 5,000,000 tokens a day
All 17 ids share 100 requests and 5,000,000 tokens a day per account. Your $10 sign-up credit is used first, at each model's discounted rate; the 3 that bill $0 per token keep working after it is spent. Hit either daily number and the free lane pauses until it resets tomorrow at 05:30 IST (00:00 UTC) - contact support to switch to a paid plan and raise your limit.

No models match that search. Try a family name such as “Claude” or part of a model id.
Showing 10 of 34. The rest are further models in each family, some with no working upstream right now.
USD per 1M tokens. “—” means no separate cached-input rate: cached input bills at the standard input rate.
Measured speed comes from the requests this gateway answered in the last 24 hours. A model needs a handful of answers before it is ranked, so quiet models sink to the bottom of that sort.
Two formats, one key
Use the SDK you already have.
Every model speaks the OpenAI format. 4 of them also accept the native Anthropic Messages format, which is what Claude Code expects.
