Welp, seems like a good day to remind people if you build on top of open models you can rest assured they will always behave exactly like the first day you downloaded the weights. (JFC)

Try Arcee Trinity Large Thinking. Just as good as day 1.

Makes me wonder how long this has already been going on without users being notified.

I had been feeling like codex was running circles around Claude code for months now.

Now I wonder if Claude code was just self nerfed.

Regardless of the intentions behind this, this is a bad product design decision. It’s bad for users, I suspect it’s bad for Anthropic on some level as well.

Saying we get to decide what kind of systems code relates to building frontier models and we will nerf it without notifying you? Insane.

Users are accusing Anthropic of silently nerfing Claude code performance and refusing to acknowledge degradations, with some sarcastically mocking the company's denials as dishonest.

How long do we expect it will be until Anthropic makes an official post clarifying the statements to not spook its customers?

@code_star feeling they wont unless the US government jumps in. Never acknowledged 4.7, 4.8 degradations anyways.

@code_star before they post it, some customer will already have swapped to codex

which makes the wait feel extra loaded?
