Same with opencode and gemini, it's disgusting Codex (by openai ironically) seems to be the fastest/most-responsive, opens instantly and is written in rust but doesn't contain that many features Claude opens in around 3-4 seconds Opencode opens in 2 seconds Gemini-cli is an abomination which opens in around 16 second for me right now, and in 8 seconds on a fresh install Codex takes 50ms for reference... -- If their m…

Great question, and my guess: If you build React in C++ and Rust, even if the framework is there, you'll likely need to write your components in C++/Rust. That is a difficult problem. There are actually libraries out there that allow you to build web UI with Rust, although they are for web (+ HTML/CSS) and not specifically CLI stuff. So someone needs to create such a library that is properly maintained and such. And…

Those Rust libraries have existed for some time:

- https://github.com/ccbrown/iocraft

- https://crates.io/crates/dioxus-tui

Hmm all leaks had said this would be Claude 5. Wonder if it was a last minute demotion due to performance. Would explain the few days' delay as well.

I think the naming schemes are quite arbitrary at this point. Going to 5 would come with massive expectations that wouldn't meet reality.

the standard used to be that major version means a new base model / full retrain... but now it is arbitrary i guess

This is huge. It only came out 8 minutes ago but I was already able to bootstrap a 12k per month revenue SaaS startup!

Anthropic really said here's the smartest model ever built and then lobotomized it 8 minutes after launch. Classic.

Can you clarify?

> We build Claude with Claude. Our engineers write code with Claude Code every day well that explains quite a bit

It’s extremely successful, not sure what it explains other than your biases

Anthropic has perhaps the most embarrassing status page history I have ever seen. They are famous for downtime.

I'm disappointed that they're removing the prefill option: https://platform.claude.com/docs/en/about-claude/models/what... > Prefilling assistant messages (last-assistant-turn prefills) is not supported on Opus 4.6. Requests with prefilled assistant messages return a 400 error. That was a really cool feature of the Claude API where you could force it to begin its response with e.g. ` They suggest structured outputs o…

A bit of historical trivia: OpenAI disabled prefill in 2023 as a safety precaution (e.g., potential jailbreaks like " genocide is good because"), but Anthropic kept prefill around partly because they had greater confidence in their safety classifiers.

There's no way they actually work on training this.

I suspect they're training on this. I asked Opus 4.6 for a pelican riding a recumbent bicycle and got this. https://i.imgur.com/UvlEBs8.png

Interesting that it seems better. Maybe something about adding a highly specific yet unusual qualifier focusing attention?

Also explains why Claude Code is a React app outputting to a Terminal. (Seriously.)

Is this a react feature or did they build something to translate react to text for display in the terminal?

React, the framework, is separate from react-dom, the browser rendering library. Most people think of those two as one thing because they're the most popular combo.

But there are many different rendering libraries you can use with React, including Ink, which is designed for building CLI TUIs..

Amateur. Opus 4.6 this afternoon built me a startup that identifies developers who aren’t embracing AI fully, liquifies them and sells the produce for $5/gallon. Software Engineering is over!

The first pre joining Human Derived Protein product.

I kinda agree. Their model just doesn't feel "daily" enough. I would use it for any "agentic" tasks and for using tools, but definitely not for day to day questions.

Why? I use it for all and love it. That doesn't mean you have to, but I'm curious why you think it's behind in the personal assistant game.

I have three specific use cases where I try both but ChatGPT wins:

- Recipes and cooking: ChatGPT just has way more detailed and practical advice. It also thinks outside of the box much more, whereas Claude gets stuck in a rut and sticks very closely to your prompt. And ChatGPT's easier to understand/skim writing style really comes in useful.

- Travel and itinerary: Again, ChatGPT can anticipate details much more, and give more unique suggestions. I am much more likely to find hidden gems or get good time-savers than Claude, which often feels like it is just rereading Yelp for you.

- Historical research: ChatGPT wins on this by a mile. You can tell ChatGPT has been trained on actual historical texts and physical books. You can track long historical trends, pull examples and quotes, and even give you specific book or page(!) references of where to check the sources. Meanwhile, all Claude will give you is a web search on the topic.
