danshipper · x · 2026-09-23
Anthropic has released Claude Opus 5.5. Dan Shipper of Every stated that after testing, some users previously converted to Codex have switched back to Claude.
Key Points:
- Price: Up to 40% cheaper than Opus 5.
- Coding Capability: Excels at large end-to-end project builds that match personal tastes; Every team member Kieran Klaassen has replaced Fable 5.1 with it for daily product development, calling it his new favorite model.
- Writing Capability: The writing is fluent and readable, but still lags behind Astra in writing tasks; reading ease score is 68.42.
- Overall Evaluation: Considered a strong candidate for a new daily primary model, even surpassing Fable 5.1 in some tests.
