Anthropic released Claude Opus 5.5 on September 22, 2026, priced at $4 per million input tokens and $20 per million output tokens.
Cheaper and Faster Than Opus 5
Anthropic says Opus 5.5 costs about 40% less to run than Claude Opus 5 on typical work and generates output more than 30% faster. TechCrunch described the release as delivering lower prices with performance comparable to Anthropic's top Fable tier.
Caching Gets Much Cheaper
Cache reads fall to $0.20 per million tokens, 60% less than Opus 5's $0.50, while cache writes drop to $5 per million from $6.25. For applications that reuse long system prompts or documents across many requests, the caching cut may matter more than the headline price.
Available Across Major Clouds
Opus 5.5 is available on the Claude Platform as well as AWS, Google Cloud and Microsoft Azure, so enterprises can adopt it inside existing cloud agreements.
A Busy Week for Model Pricing
The release landed the same day OpenAI launched GPT-6 Sol and Luna with 50% price cuts. Two major price resets in one day are a good prompt to revisit model choices in any AI feature budgeted earlier in the year.
