## FAQ

### Can I compare GPT-OSS 120B and BERT base / Fine-tuned on case law and contract corpora Chalkidis et al. (2020) (ContractNLI) on BenchLM yet?

Not fully yet. BenchLM is tracking both models, but sourced benchmark coverage is still incomplete for a fair score-level comparison.

### Why does this page show "coming soon" values?

BenchLM only calls winners when public benchmark coverage is available on both sides of the comparison.
