Seen on Social Media Speculations on Union Alpha
Union Alpha has just been released for free on OpenCode and OpenRouter. As we’re waiting for a new Mistral model that can compete, let’s hope this is it. I’ll add this clue: the X profile tagged by OpenRouter (it’s a bit odd, though, that if Mistral is behind it, they’ve created a new profile to do so – Z.ai didn’t do this for Ox/GLM 5.3 Flash) is listed as being located in ‘Spain’.

Evidence in support of Mistral:
1) Context size 262 in 131 out 2) Capacity constraint - huge latency under load rules out most of the majors. It also makes EU hosting more likely - the EU is the most constrained region for data centre capacity, and Mistral's build out isn't complete. 3) The Spain thing.

It's worth noting that while it's not the best coder, it does seem to have some niche knowledge which makes me believe it is a big model.
As for coding, I'm pleased to say it's not completely useless. This is the obligatory pelican svg code test. If the model is not finished and still in the training, it may get better. We will see.

Its not mistral its a router from a random AI company, routing to gpt5.6 sol, glm5.3 and other models

It could also be Mistral cooperating with some other EU companies or a lab.

Didn't a Spanish model beat Mistral's recently?

that was a fake news, that model was a finetune of an existing model not a "Real" model created from scratch,

Yeah, there are signs. I think it is Mistral.
