The best open models today have been “good enough” to do most knowledge work for a few months. This might be the first US one good enough too. That’s a big deal.

Open weight US based Opus 5.5 within 12 months.

Inception Mercury 3 and Particle-1's model are also good.

(I am assuming Inception is an American company, not sure TBH)

Seems unlikely. Maybe open weight at all near there? That'd be great.

Things have been remarkably "not terrible" since approximately the release of Laguna S 2.1 a while back in early summer 2026, which is now outdated within the past 6 month time frame by other, better non CN open weight models.

I'm not saying that any of them are to the level as a deepseek v4.1 flash 1017 or similar but they're catching up. The most recent huge mistral release is also grounds for an optimistic view.

Muse Glimmer is pretty good.

That’d be the inflection point I’m waiting for!
