The price card for Anthropic's Claude Opus 5.5 shows per-token rates 20% below its predecessor, while the company estimates 40% lower costs for typical usage billed by token.
Anthropic's rate card puts output at $20 and input at $4 per million tokens for Claude Opus 5.5. The company says those unit prices are 20% below Opus 5's.
Anthropic's 40% calculation describes typical workloads charged by token use and compares Opus 5.5 with Opus 5. It is not a task-by-task price comparison between Claude and competing services.
The final bill also varies with the quantity of input and output tokens a workload uses. Google sets Gemini 4 Argon's introductory API fees through Nov. 30 at $2 for every million input tokens and $10 for every million output tokens. The published schedule changes the input and output charges to $4 and $20 per million, respectively, on Dec. 1.
