Let that sink for a moment:

• Opus 5.5 costs 40% less compared to Opus 5
• performs at Fable 5.1 level
• is 30% faster in output
• and you get a banked reset on top of that.

They chose war with OpenAI. We are in such a wild race!

Quoting @claudeai: One more thing: we’re increasing five-hour usage limits on Pro, Max, and Team plans. We’re also providing subscription users a rate limit reset, which you can save and use whenever you choose.
