Frequently Asked Questions

Which is better overall, Llama 3.1 70B or Yi-Large?

Yi-Large has the higher preference Elo in our latest snapshot (1,430). “Better” still depends on coding, price, and latency — see the table.

Which is better at coding, Llama 3.1 70B or Yi-Large?

Yi-Large leads SWE-bench at 53.8% vs 40.2%. SWE-bench is one harness, not your repo.

Which is cheaper to run in production?

Yi-Large output tokens are $0.3/1M versus $0.4/1M. Input prices and retry rates still move the real bill.

Which is faster, Llama 3.1 70B or Yi-Large?

Can I self-host either model?

Llama 3.1 70B is marked open-weights in our catalog. The other side is a closed API. Check the provider license before you ship weights.

Are these scores from CompareLLM’s own evals?

No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.

What does preference Elo mean on this page?

Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. Llama 3.1 70B and Yi-Large Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
