David Gewirtz / ZDNET: Opus 5 improves coding, reasoning efficiency, and prompt-cache-friendly tool use, and is priced at 5/1M input tokens and 25/1M output, same as Opus 4.8 — ZDNET's key takeaways — Opus 5 targets coding, knowledge work, and agent workflows. — Anthropic says it uses fewer tokens for similar quality.

GPT-5.5 is priced at 5/1M input tokens and 30/1M output tokens, double GPT-5.4's pricing; GPT-5.5 Pro costs 30/1M input tokens and 180/1M output tokens (Carl Franzen/VentureBeat)
Claude Sonnet 5 costs 2 per 1M input tokens and 10 per 1M output tokens through August 31, after which prices rise to 3 and 15, respectively (Zac Hall/9to5Mac)
Claude Opus 4.8 and Sonnet 5 seem worse at tool calls than older models, likely due to post-training that assumes Claude Code-like harnesses as targets (Armin Ronacher/Armin Ronacher's Thoughts and Writings)
Anthropic says 'some routine tasks like coding and debugging' on Fable 5 'will fall back to Opus 4.8' in 'the near term' as it works to 'reduce false positives' (@anthropicai)
