llmstep: [L]LM proofstep suggestions in Lean

https://github.com/wellecks/llmstep

This model is a Pythia-2.8b-deduped language model fine-tuned on LeanDojo Benchmark 4.

The model is fine-tuned on sequences of the form:

[GOAL]tactic-state[PROOFSTEP]next-tactic<|endoftext|>

This format corresponds to the proofstep objective from Han et al ICLR 2022.
The python/train directory in the repository shows how the model was fine-tuned.

Please see the repository for more details.
