It is definitely not this. Anthropic has thousands of employees making probably > 100,000+ tiny changes across the entire stack and infrastructure everyday.
The compounding effect can definitely cause temporary regressions in some domain or use-case that doesn’t have really good coverage in their internal tests.
What makes this particularly challenging in the case of LLMs is how changing some language in the prompt can vastly affect the output.
But this is less true as models become larger and additional parameters are able to capture each and every possible nuance of the language. I’d say caching and cache tuning or token optimization/tweaks to thinking are the biggest culprits today.

What "stack" do you have in mind here?
An LLM is a monolithic slab of weights, not millions of lines of code spread over many microservices. The changes they make will be showing up in web and app responsiveness, and in the performance of training runs for one or more next versions of the that monolithic slab of weights, but I'd be surprised if there's a way for their efforts to show up directly in a "has this model been nerfed?" sense.
Both Anthropic and OpenAI used to have multiple snapshots per model; both seem to have switched to updating version numbers when anything changes, looking at the "snapshots" section in their recent and old models: e.g. <a href="https://developers.openai.com/api/docs/models/gpt-4o" rel="nofollow">https://developers.openai.com/api/docs/models/gpt-4o for how far back I had to go to find multiple snapshots on an OpenAI model, and <a href="https://platform.claude.com/docs/en/about-claude/model-deprecations" rel="nofollow">https://platform.claude.com/docs/en/about-claude/model-depre... seems to be a more useful list for Anthropic, but both are now things they did a year ago.
