The context window has been shattered: Subquadratic debuts a 12M token window

For Claude Code, I feel 1M is enough. I've had a compaction once, but that was because I was forcing Claude to do something it clearly had a hard time understanding.

For general chat bots where the user doesn't understand what a context window is, what do you do about context? Latest few messages and then a memory tool? Compaction?

This is so interesting to me, I frequently experience compaction on long running features and still find Claude is better than starting with fully fresh prompts.

Every dev seems to use these tools differently.

Claude does compaction in the regular web chat interface now, too

I feel the 1M context is way too large —- the model gets ”drunk” way before it gets anywhere near 1 million. Imo the 1M context window is a huge downgrade.

I use a tool called context-mode. Update agent to save session summary every 100k tokens
