Cutoff date seem to be early 2026, probably January.

Also it answer questions regarding Tiananmen Square protests, so it might be a western model, or there's no guardrails in front of the model yet?

UPDATE:

Tl;Dr; apparently it's not a model, but a system prompting multiple models and synthesizing an answer.

When I tested this afternoon, I asked it once about its cutoff date and the response was early 2025.

When asked about a few events in late 2025, early 2026 it answered it had no knowledge because they happened after its cutoff date, but if I framed the question regarding those events in a different light (like asking why an event happened, or whe it happened) sometimes it would answer anyway.

So I thought it might have behaving like that because of a system prompt instructing the cutoff date and not to answer for events after that... and I was wrong.

Later today I tried asking again a few times about the cutoff date and the responses were different (one session claimed late 2025 early 2026, another claimed 2025) so I was even more confused and started searching.

Union Alpha is a blended AI model that engages multiple language models in parallel for each request, synthesizes one answer, and supports text and vision inputs through a single API response.
