Claude Sonnet 5.5 is out today
The model is more than 30% faster than Sonnet 5, and costs up to 30% less for most tasks, with the same token price. Its real strength is shown by fixing bugs, building documents, slides, tables, and improving interfaces, and with some proxy programming tests it comes close to Opus 5.5.
Made this launch video with 5 prompts in Claude Opus 5.5.
I was doubting the X gurus. turns out it's ridiculously easy. no After Effects. no editor. my most technical instruction was "make it more Apple".
Anthropic leaked a file where 4 agents draw a system in 60 minutes that agencies quote at $1.4M
The hour costs $4.40 and the quote for the same sheet is $1,400,000 ingest → store → api → workers → ui → billing six modules, four pinned versions, 24 endpoints and 11 tables,
Anthropic cooked OpenAI in just one week 😭
I think, GPT-6 Sol is nowhere near Sonnet 5.5 in realism for this scene. Sonnet 5.5 is a huge jump from Sonnet 5, especially in frontend, 3D, speed, and prompt understanding. Honestly, it feels close to Opus 5.
