Claude Opus 5.5 costs $4.00 per million input tokens and $20.00 per million output tokens. A typical chat reply of 3,000 input and 500 output tokens costs about 2 cents. Cached input is $0.20 per million, and the Batch API halves the price.
Yes. Opus 5.5 costs $4.00 input and $20.00 output per million tokens, 20% less than Opus 5 at $5.00 and $25.00. Cache reads are 60% cheaper: $0.20 instead of $0.50.
Reading from the cache costs $0.20 per million tokens on Opus 5.5, 5% of the normal input price. Writing to the cache costs $5.00 per million for 5 minutes or $8.00 for 1 hour. Caching pays off after the first cache read.
No. Opus 4.6 and later include the full 1M-token context window at the standard price, so a 900,000-token request costs the same per token as a short one.
Claude Sonnet 5.5 costs $2.00 input and $10.00 output per million tokens, 2 times cheaper than Opus 5.5. Claude Haiku 5.5 costs $0.10 and $0.50, 40 times cheaper. Many teams use Opus only for the hardest steps.
No, not on the Claude API. Opus 4 shut down on June 15, 2026 and Opus 4.1 on August 5, 2026; both cost $15.00 input and $75.00 output. They remain available on some cloud platforms, such as Claude models on Google Cloud.
Fast mode gives faster output at a premium: $8.00 input and $40.00 output per million tokens on Opus 5.5, and $10.00 input and $50.00 output on Opus 5 and Opus 4.8. It can't be combined with the Batch API.
Tag each Opus call with the customer it served, then price it at these rates and add it up by customer. Ganivra does this automatically with two lines of the Python SDK, and shows each customer's Opus cost next to what they pay you.
