Two days ago, we open-sourced THX-01, our 322M-parameter decision model that outperforms Jev on several benchmarks and can even run locally on a PHONE!
Yesterday, we opened the THX-01 API to everyone for free.
And the response has been incredible. We've already processed:
- 25M+ tokens - 211,000+ decisions
What's available: - Free API: 200 decisions/month - Full model weights, source code, and training scripts - Apache 2.0 license - 18 trained languages - Local inference, even on mobile devices
Everything is open-source, and we're just getting started!
We just open-sourced THX-01, a 322M decision model. Most AI decisions in production are classification in disguise: which team gets this ticket, is this email phishing, what's the total on this invoice. Calling a large LLM for each one is slow, expensive, and its confidence means nothing. THX-01 is built for exactly these decisions. You send it a message or document plus typed questions, and in one forward pass (~10 ms) it returns: - an answer to every question, with a calibrated probability for each option - exact numbers stated in the document, or null if the number isn't there - verbatim quotes and the passages that support each answer On our 4-language support-ticket benchmark it matches Claude Sonnet 5.5 (98.4 vs 98.5) and is about 150x faster. Because its confidence is calibrated, it handled about 75% of tickets automatically with zero errors. pip install thx01 doofz/THX-01
THX-01 now has a free API. No key, no sign-up. Yesterday we open-sourced THX-01, our 322M decision model. Today we're opening the hosted API to everyone for free. Send a message or document with typed questions and get every answer in one forward pass, about 10 ms, with a calibrated probability for each option: curl https://api.hal-x.ai/v1/systemone \ -H "Content-Type: application/json" \ -d '{"state": "My card was charged twice for one order", "questions": {"team": {"type": "choice", "question": "Which team handles this?", "criteria": {"billing": "billing", "tech": "technical", "sales": "sales"}}}}' What it answers: choice, yes/no, score, exact number from the text (or null if it isn't there), verbatim excerpt, and "cite": true for supporting passages. - Free tier: 200 decisions per minute per IP - On our 2,843-ticket benchmark in four languages: 98.4% vs 97.4% for TypeSafe Jev, at about 10 ms instead of 331 ms - 18 trained languages - Weights are Apache 2.0: pip install thx01 Model: doofz/THX-01 Demo: doofz/THX-01-demo
