Anthropic's AI downgrade stings power users

TL;DR

Anthropic users across online forums are raising the same complaint: Claude suddenly feels… bad. Why it matters: The backlash lands just as Anthropic is testing a more powerful model, Mythos — raising questions about whether cutting-edge AI is becoming less accessible even as it gets more capable. Driving the news: Over the past few weeks, users on X, GitHub and Reddit have been swapping anecdotes, benchmarks and prompts in an effort to pinpoint what changed and why. "Claude has regressed to the point it cannot be trusted to perform complex engineering," an AMD senior director wrote in a widely shared post on GitHub. Others have posted side-by-side outputs and benchmarks they say show Claude generating answers that are less accurate or nuanced. Much of the speculation centers on whether Claude has been deliberately scaled back — what users are calling "nerfed" — either to control costs o.

Nauti's Take

User feedback catching performance regressions before they become entrenched is genuinely valuable — it's the signal labs need to improve. The concern is real though: if Claude has been silently degraded to manage costs, that's a trust problem no new model fixes.

Power users deserve a transparent changelog, not speculation.
