HAL-X THX-01

THX-01 is HAL-X’s 322M-parameter Apache-2.0 decision model (not a text generator). It answers typed questions about a state (message, ticket, document, or JSON) in one forward pass with calibrated probabilities.

Hosted API (Path A)

• Docs: https://api.hal-x.ai/docs/thx-01/
• Registry id: thx-01 on the decide service
• Env: HALX_API_KEY (HAL-X console; grant /v1/systemone for model thx-01)
• Endpoint: POST https://api.hal-x.ai/v1/systemone (TypeSafe/Jev-compatible for choice, noul, score; THX also supports number, excerpt, and "cite": true)

opentryon decide --model thx-01 \
  --state "My card was charged twice" \
  --questions '{"team":{"type":"choice","instructions":"Which team?","criteria":{"billing":"billing","tech":"technical"}}}' \
  --dry-run

Local weights (Path B)

• Weights: https://huggingface.co/doofz/THX-01
• Package: pip install thx01 (included in opentryon[local])
• Registry id: thx-01-local

opentryon decide --model thx-01-local \
  --state "My card was charged twice" \
  --questions '{"urgent":{"type":"noul","instructions":"Needs help today?"}}'
