Anthropic has introduced Opus 5.5 and reduced its pricing by 20%, according to an update on Tuesday. The new model costs $4 per million input tokens and $20 per million output tokens, down 20% from Opus 5's prices. Cache reads have dropped to $0.20 per million from $0.50, while cache writes have decreased to $5 from $6.25, resulting in overall savings of nearly 40%.
Opus 5.5 also generates output 30% faster and uses fewer tokens to complete tasks. A fast mode for Claude Code and the Claude Platform has been introduced, running up to 2.5 times faster at $8 per million input tokens and $40 per million output tokens. Opus 5.5 has shown performance comparable to Fable 5.1 on most workloads, excelling in several agentic coding benchmarks.
It outperformed Fable 5.1 and GPT-6 Astra in terminal and coding tasks at a lower cost. Developers are advised to run their own evaluations before deploying workloads to production. Fewer tokens and steps are being used, leading to real efficiency gains in certain task profiles.
