Model reference · open weights
MathForm is an open-weight language model from openbmb, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
MathForm-8B is an autoformalization model that translates natural-language mathematical statements into Lean 4. It is released with the paper MathForm: Scaling Mathematical Autoformalization with Knowledge Retrieval and Verification-Guided Refinement. The model is trained on FormalVerse through supervised fine-tuning followed by reinforcement learning using Lean compilation and semantic-consistency feedback. Results Usage Transformers vLLM SGLang Both servers expose an OpenAI-compatible API at http://localhost:8000/v1/chat/completions. Recommended Settings Evaluation The evaluation pipeline, benchmark files, and Pass@k scripts are available in the MathForm repository. Compilation checks require a running Kimina Lean Server. The experiments use Lean 4.21.0. License This project is licensed under the Apache License 2.0. Citation

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API
Once AxForge deploys mathform for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (mathform below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/chat/completions \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"mathform","messages":[{"role":"user","content":"Hello"}]}'
Licence
Open weights under apache-2.0 — commercial use is permitted. Deploy it on AxForge EU hardware on request. Read the licence ↗
