Rows without prices are deprecated/retired models kept for their shutdown dates — see the deprecation tracker. Missing a model you need? We only publish prices we've checked against a provider's own page — request a model.
New to per-token pricing? Start with how to estimate LLM API costs — the cost formula plus the four corrections (tokenizer differences, invisible tokens, caching, deprecations) that turn these rate cards into a real budget.
Frequently asked questions
How often are these prices checked?
Every price is read directly from the provider's official pricing page and stamped with the date we last checked it — currently 2026-11-02. If the data goes more than 30 days without re-verification, every page in this section shows an overdue warning banner instead of quietly going stale.
What does per-MTok pricing mean?
Per million tokens. A model listed at $2.50 input / $15 output charges $2.50 for every 1,000,000 tokens you send it and $15 for every 1,000,000 tokens it generates. A token is roughly 4 characters of English text.
Which LLM API is cheapest right now?
By combined rate, Gemini 2.5 Flash-Lite is the cheapest active model we track, at $0.1 input / $0.4 output per MTok (verified 2026-11-02). Cheapest per token is not always cheapest per task — tokenizers differ between model families.
Do these prices include caching or batch discounts?
No — the table shows base per-token rates. Cache reads (about 0.1x the input price on Anthropic models; see the cache-read column) and batch APIs (about 50% off) can bring real workload costs far below the base rate.
