Oh I didn't know you could type /model claude-opus-4-6 and still use it.

Thanks!

Yes, and /model claude-opus-4-6[1m] gets you the larger context window. Happy to help :)

Thanks for the hint, but is a large context window actually that useful? I tend to get garbage too often with a normal big context window.

IME, based on an in-house bench it's still good to about 20% on the 1M for 4.6 and 4.7 with a code base >50k loc. The trick I used before switching providers was to have it write a handoff when it hit ~18% of context and reset.

There are also many people running 4.5 with specific parameters that claim to be having luck.

The best way is to code in a way that doesnt break via model instruction nuances changing. 4.7 is superior
