Are there evals showing how this improves outputs?

#12Claude Code 2.1.75 now no longer delineates between base Opus and 1M Opus: it's the same model. Oddly, I have Pro where the change supposedly only for Max+ but am still seeing this to be case. EDIT: Don't think Pro has access to it, a typical prompt just hit the context limit. The removal of extra pricing beyond 200k tokens may be Anthropic's salvo in the agent wars against GPT 5.4's 1M window and extra pricing for t…
No change for Pro, just checked it, the 1M context is still extra usage.

#13This is incredible. I just blew through $200 last night in a few hours on 1M context. This is like the best news I've heard all year in regards to my business.
What is OpenAIs response to this? Do they even have 1M context window or is it still opaque and "depends on the time of day"

#14The weirdest thing about Claude pricing is their 5X pricing plan is 5 times the cost of the previous plan.
Normally buying the bigger plan gives some sort of discount.
At Claude, it's just "5 times more usage 5 times more cost, there you go".

#15Noticed this just now - all of a sudden i have 1M context window (!!!) without changing anything. It's actually slightly disturbing because this IS a behavior change. Don't get me wrong, I like having longer context but we really need to pin down behaviour for how things are deployed.
Anthropic is famous for changing things under your feet. Claude code is basically alpha software with a global footprint.

#16I'm getting close to my goal of fitting an entire bootstrappable-from-source system source code as context and just telling Claude "go ahead, make it better".

#18What about response coherence with longer context? Usually in other models with such big windows I see the quality to rapidly drop as it gets past a certain point.

Did u use the API or subscription?

#20The big change here is: > Standard pricing now applies across the full 1M window for both models, with no long-context premium. Media limits expand to 600 images or PDF pages. For Claude Code users this is huge - assuming coherence remains strong past 200k tok.
Is it ever useful to have a context window that full? I try to keep usage under 40%, or about 80k tokens, to avoid what Dex Horthy calls the dumb zone in his research-plan-implement approach. Works well for me so far.
