> Opus 4.7 uses an updated tokenizer that improves how the model processes text. The tradeoff is that the same input can map to more tokens—roughly 1.0–1.35× depending on the content type. caveman[0] is becoming more relevant by the day. I already enjoy reading its output more than vanilla so suits me well. [0] https://github.com/JuliusBrussee/caveman/tree/main

I hope people realize that tools like caveman are mostly joke/prank projects - almost the entirety of the context spent is in file reads (for input) and reasoning (in output), you will barely save even 1% with such a tool, and might actually confuse the model more or have it reason for more tokens because it'll have to formulate its respone in the way that satisfies the requirements.

I wonder if you can have it reason in caveman

Introducing a new upgraded slot machine named "Claude Opus" in the Anthropic casino. You are in for a treat this time: It is the same price as the last one [0] (if you are using the API.) But it is slightly less capable than the other slot machine named 'Mythos' the one which everyone wants to play around with. [1] [0] https://claude.com/pricing#api [1] https://www.anthropic.com/news/claude-opus-4-7

If you're building a standard app Opus is already good enough to build anything you want. I don't even know what you'd really need Mythos for.

Also 640 KB ram ought to be enough for everybody.

I hope this will fix up the poor quality that we're seeing on Claude Opus 4.6

But degrading a model right before a new release is not the way to go.

Too late, personally after how bad 4.6 was the past week I was pushed to codex, which seems to mostly work at the same level from day to day. Just last night I was trying to get 4.6 to lookup how to do some simple tensor parallel work, and the agent used 0 web fetches and just hallucinated 17K very wrong tokens. Then the main agent decided to pretend to implement tp, and just copied the entire model to each node...

That's wild that you think 4.6 is bad..... Each model has its strengths and weaknesses I find that Codex is good for architectural design and Claude Is actually better the engineering and building

> where previous models interpreted instructions loosely or skipped parts entirely, Opus 4.7 takes the instructions literally. Users should re-tune their prompts and harnesses accordingly. interesting

I like this in theory. I just hope it doesn't require you to be be as literal as if talking to a genie.

But if it'll actually stick to the hard rules in the CLAUDE.md files, and if I don't have to add "DON'T DO ANYTHING, JUST ANSWER THE QUESTION" at the end of my prompt, I'll be glad.

For anyone who was wondering about Mythos release plans: > What we learn from the real-world deployment of these safeguards will help us work towards our eventual goal of a broad release of Mythos-class models.

The most highly anticipated model looking forward to using it

Same for me.

I cancelled my subscription and will be moving to Codex for the time being.

Tokens are way too opaque and Claude was way smarter for my work a couple of months ago.

I've been using it with `/effort max` all the time, and it's been working better than ever.

I think here's part of the problem, it's hard to measure this, and you also don't know in which AB test cohorts you may currently be and how they are affecting results.

Claude Code hasn't updated yet it seems, but I was able to test it using `claude --model claude-opus-4-7` Or `/model claude-opus-4-7` from an existing session edit: `/model claude-opus-4-7[1m]` to select the 1m context window version

Does it run for you? I can select it this way but it says 'There's an issue with the selected model (claude-opus-4-7). It may not exist or you may not have access to it. Run /model to pick a different model.'
