THX-01 — local AI model by HAL-X AI
Written by Jakub Rusinowski · Last updated
HAL-X AI's 322M multilingual decision model: an mmBERT-base encoder with a decision head, post-trained in 18 languages. Besides choice, yes/no and score it returns numbers, verbatim excerpts and citations from a document.
Variants
The smallest THX-01 variant needs about 1 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache.
| Model | VRAM at Q4 | VRAM | Context | Run it |
|---|---|---|---|---|
| THX-01 322M → 322M | ~1 GB | 1,024 tokens per question | thx01.server :8095 |
Memory is quantized weights plus overhead at Q4_K_M, from the same engine as the GPU & VRAM checker.
How to run THX-01 locally
Install Ollama, then pull the tag.
Served by thx01.server (default port 8095). This model does not run in Ollama.

The cheapest catalogued GPU that runs THX-01 locally (min 1 GB VRAM) is the Intel Arc B570 (10 GB).
THX-01 — frequently asked questions
How much VRAM does THX-01 need?
THX-01 needs about 1 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: THX-01 322M (1 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Can I run THX-01 on an RTX 4090 (24 GB)?
Yes — THX-01 runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.
What quantization should I use for THX-01?
Q4_K_M is the best balance of quality and VRAM for THX-01 in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
How do I run THX-01 locally?
THX-01 is a decision model: it is called over an HTTP endpoint (/v1/systemone), not chatted with. Where a variant is available in Ollama 0.35 or newer, pull it with `ollama pull` and send requests to the local server; the others ship their own server. Each variant page shows the exact commands for that model.
