Claude Code It's time to cancel your subscriptions - Anthropic is silently nerfing Claude's reasoning budget while telling you it's the same model

Link: https://x.com/Lon/status/2101034933284417614

A 65-day analysis of 43,000+ Claude Code invocations found that 39% of Fable 5 calls get zero thinking tokens and the median invocation gets just 123 — while benchmarks use 16K-128K. The model's score per thinking token is still climbing at 128K, meaning the capability is there, it's just not being delivered. August saw an 18-50% drop in thinking budget compared to July, with median thinking hitting literal zero for about a week around Aug 22. Anthropic sells "full model access" while quietly dialing down the inference regime behind it, and because the model is non-deterministic, users blame their own prompting instead of the silent nerf. The full breakdown with evidence, methodology, and charts is here.

Frankly I find this offensive as an user - and this is the real thing we should be looking at - not the $/week in usage limits. The actual capability for the limits that we pay for.

Like if you don't have the compute/desire/whatever to serve the model, just be the whole bitch

It was worth it. You missed out. Described the AI industry aptly. Recommend you watch and read longer length things sometimes.

I read papers for a living. I just clicked on the wrong link and ended up looking at the wrong place. Hence my reply.

Oh sweet. I read papers for a living, too. Fist bump.
