Frequently Asked Questions

Which is better overall, GPT-5 mini or Mistral Large 3?
Mistral Large 3 has the higher preference Elo in our latest snapshot (1,456). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, GPT-5 mini or Mistral Large 3?
Mistral Large 3 leads SWE-bench at 55.4% vs 52.4%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?
GPT-5 mini output tokens are $2/1M versus $6/1M. Input prices and retry rates still move the real bill.
Which is faster, GPT-5 mini or Mistral Large 3?
GPT-5 mini has the lower time-to-first-token (140 ms vs 190 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?
GPT-5 mini accepts 400k tokens versus 256k.
Can I self-host either model?
Neither model is marked open-weights here. You are comparing hosted APIs.
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. GPT-5 mini and Mistral Large 3 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
