No technical report published yet, unlikely code or weights will be either given VC funding.

It’s probably something like deepseek’s native sparse attention with content based granularity. They might not be publishing anything because it’s not such a strong value proposition and doing so would lead to commentary that would tank their investment opportunities.

Or maybe because giving it away would tank their investment opportunities.

There's ways and means. Pushing something out in the sub-30B range would gain them mindshare and they could keep bigger models to themselves. I can't see any indication of what size their model is though.

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?

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.

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

Have they published?
