THX-01

HAL-X's THX-01 joins the Decisions family: a 322M multilingual decision model with calibrated probabilities, free on AnyRouter.

hal-x/thx-01 is a 322M decision model from HAL-X AI. It is trained so that its probabilities are calibrated: a 0.8 means it is right about 80% of the time. It answers every question in one pass of about 10 ms, was post-trained in 18 languages, and supports 100+. Send state and typed questions (noul / choice / score) to POST /api/v1/decisions and get a probability for each answer, not chat text.

It is **free**: no BYOK key needed, $0 per request. The model reads up to 1,024 tokens per question and cuts longer state, so keep it short — tickets, messages, short records.
