Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

A simple illustrative guide for Devs to build with Jev @typesafeai (agent-friendly)

The reframe is right. People keep asking whether Jev replaces GPT, when the better question is how many places in your stack are using an LLM just to pick an enum. Structured decisions with confidence are a cleaner fit for retries, routing, and tool selection than another free-form completion you have to regex afterward. Bookmarking the guide. The useful test for me will be whether the confidence scores stay calibrated once you leave the demo prompts.

Designing at the speed of voice. Speaking the layout into existence into existence with Jev, @shadcn and a local transcription model.

if you tried hyperframes, you would know the agentic video stack is being built on code-gen but SWE-bench code v.s. code-to-video that feels alive are two different things we built the Code2Video Bench, in collab w/ Google DeepMind & @Kaggle frontier labs can finally get good at agentic video tasks

does jev stay predictable when typed questions expand across larger production workflows?

Jev is a super fast video editor! Edited this entire video in less than a minute, and here's how: First, I transcribed raw vid locally with word timestamps, cut it into 16 beats, then asked Jev these seven questions about every beat: does this line need a visual at all? which card template? (18 to pick from, premade) which text effect? which transition into it? how hard do we punch in on the face? which sound effect? which word gets emphasised? Plus five about the video as a whole. Style, colour, caption treatment, energy, progress bar. 117 questions answered by jev < 1 s ~ $0.0017 Using @typesafeai via @LiteLLM

Best overview of Jev to date! Thank you @MisbahSy!

Jev is definitely insane! What if you could just point and build a website? Uses json-render @ctatedev @LiteLLM gateway to call Jev

May I ask how to achieve all this?
