Dan(@DanDr1s):🚨 Claude Sonnet 5.5 and Haiku 5.5 are coming in the next few weeks. Both will get many of Opus 5.5’s performance, efficiency and safety improvements. Anthropic is also raising Pro, Max and Team usage limits, plus giving users a banked reset.

🚨 Claude Opus 5.5 is OUT. Beats Fable 5.1 on EVERY benchmark in this chart. Even beats GPT-6 Astra on Terminal-Bench: 66.4% vs 57.9%. And scientific research nearly doubles over Opus 5: 29% → 58.7%. Okay Anthropic 👀
