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.

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.

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.

Oh look it was too powerful to release, now it’s just a matter of safeguards. This story sounds a lot like GPT2.

> 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.

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...

Funny because many people here were so confident that OpenAI is going to collapse because of how much compute they pre-ordered. But now it seems like it's a major strategic advantage. They're 2x'ing usage limits on Codex plans to steal CC customers and it seems to be working. I'm seeing a lot of goodwill for Codex and a ton of bad PR for CC. It seems like 90% of Claude's recent problems are strictly lack of compute r…
