This 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"

Did u use the API or subscription?

Max subscription and "extra usage" billing

The 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".

5 for 5

It is not the plan they want you to buy. It is a pricing strategy to get you to buy the 20x plan.

Compared to yesterday my Claude Max subscription burns usage like absolutely crazy (13% of weekly usage from fresh reset today with just a handful prompts on two new C++ projects, no deps) and has become unbearably slow (as in 1hr for a prompt response). GGWP Anthropic, it was great while it lasted but this isn't worth the hundreds of dollars.

I think they are both subsidized so either is a great deal.

Yeah, morning eastern time Claude is brutal.

Is there a writeup anywhere on what this means for effective context? I think that many of us have found that even when the context window was 100k tokens the actual usable window was smaller than that. As you got closer to 100k performance degraded substantially. I'm assuming that is still true but what does the curve look like?

Isn't transformer attention quadratic in complexity in terms of context size? In order to achieve 1M token context I think these models have to be employing a lot of shortcuts.

I'm not an expert but maybe this explains context rot.

can someone tell me how to make this instruction work in claude code

"put high level description of the change you are making in log.md after every change"

works perfectly in codex but i just cant get calude to do it automatically. I always have to ask "did you update the log".

The 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.

The quality with the 1M window has been very poor for me, specifically for coding tasks. It constantly forgets stuff that has happened in the existing conversation. n=1, ymmv
