    The long-context tier was withdrawn: prompts over 200K tokens now return an error, so only the standard card applies. Standard rates are unchanged from launch.

    1M-token context (beta, usage tier 4 and custom rate limits at first) with premium rates when input exceeds 200K tokens. Input and output above 200K are quoted; the cache rates above 200K ($7.50 5m write, $12 1h write, $0.60 read) apply the official multipliers to the $6 long-context input price and are not quoted as numbers. Batch rates above 200K ($3 input, $11.25 output) apply the quoted rule that the Batch API 50% discount applies to long context pricing. Prompts up to 200K keep the standard card.

Gaps in this history

Batch rates for prompts over 200K tokens (2025-08-12 to 2026-04-30) are not printed as numbers; the recorded $3 input and $11.25 output are derived from the docs' stated rule that the 50% batch discount applies to long-context pricing.
