Sonnet 5.5 improves on Sonnet 5 across benchmarks, in some cases dramatically.
It’s a faster, lower-cost complement to Claude Opus 5.5, strongest at well-scoped everyday tasks, fixing bugs, and creating polished documents, slides, and spreadsheets.
the right way to use model capabilities is not to ship 10x more features to prod
it's to spend more time understanding your users, trying experiments, building prototypes, learning about things you don't understand so that you can ship things that actually work
Opus 5.5 is the result of your feedback.
It communicates clearly, it's cheaper per token than Opus 5.0 with the intelligence of Fable 5.1, it’s very token efficient and works across every effort level.
We're also increasing 5h rate limits & giving you a banked reset.
Introducing Jev Model Router for Claude Code
This Claude Code Mod lets you use Jev through its direct @typesafeai API or @vercel AI Gateway
With every request you send to Claude Code, Jev classifies the subagent model, main model (only at session start to avoid breaking the cache), and effort level
Install it with one command:
npx claude-code-templates@latest --mod productivity/jev-model-router

does Jev understand colour?
incredible model, very cheap and fast. definitely feels like a leap forward for creating new UX/UI paradigms on top of modern language models.
