80% of US adults who report using Claude in the previous week live in households earning $100,000 or more a year, compared to 37% of Meta AI users. Other major providers cluster in a relatively narrow band, with 56-64% of users in $100,000+ households.

An obvious way to release Mythos class models with uncertain autonomous ability is to make them only available on the website, like Gemini Deep Think or ChatGPT Pro. Minimal risk of being used for autonomous hacking, but accessible to people who have hard problems to solve.

I don’t think we’re all hallucinating, there’s something seriously wrong about 4.7. Just tried it on the same two prompt (what’s the best GC approach for Bend). 4.7 simply lies a lot, ignores information right on its context, makes bad proposals. This is really weird?

Claude remains irreducibly Claude. If you know, you know. (The fact that models have distinct personalities that are consistent across generations is technically interesting, it also makes it very easy to use new releases when they come along, because they feel very similar).

It’s fascinating is how little of Claude Code is actually “”intelligence.”” This study found a tiny reasoning core wrapped in massive infrastructure, and even quantifies it. → Only ~1.6% of the system is actual decision logic, while ~98.4% is operational harness: ~512K lines

My one takeaway from the leaked Claude Code: a good agent harness should get out of the way. As @polynoamial once put it, “”Your fancy AI scaffolds will be washed away by scale”” Claude Code’s harness is the opposite of a fancy scaffold: it’s simple, but to the point ;

tldr: claude code changed some harness settings which degraded perf. these small harness tweaks can matter a lot! 1. default reasoning high -> medium 2. bug that accidentally evicted thinking blocks on every turn in session (march 26-april 10). was a change to help with cache

A major lesson to take away from Opus 4.7 is that, while there is a lot of arguments about implementation choices and personality, models keep improving measurably on economically important tasks with each release (it has been two months since Opus 4.6), with no signs of slowdown

I’ll give Anthropic credit for moving quickly. Opus 4.7 Adaptive Thinking now triggers thinking much more often, including for the tasks it failed at yesterday. That also means it is doing a lot more web search. So far, a large improvement in output quality on non-coding tasks.

The continuing gap between the capabilities of Gemini Pro 3.1 (very good model) and the capabilities of the Gemini app/website is odd. The model can do what Claude/GPT can do, but there is a minimal harness for tools (file creation, research etc), no auditable CoT/actions, manual

I think the adaptive thinking requirement in Claude Opus 4.7 is bad in the ways that all AI effort routers are bad, but magnified by the fact that there is no manual override like in ChatGPT. It regularly decides that non-math/code stuff is “”low effort”” & produces worse results.
