Frequently Asked Questions

Which is better overall, Codestral 25.01 or Grok 3?

Grok 3 has the higher preference Elo in our latest snapshot (1,405). “Better” still depends on coding, price, and latency — see the table.

Which is better at coding, Codestral 25.01 or Grok 3?

Codestral 25.01 leads SWE-bench at 51.8% vs 51.4%. SWE-bench is one harness, not your repo.

Which is cheaper to run in production?

Codestral 25.01 output tokens are $0.9/1M versus $15/1M. Input prices and retry rates still move the real bill.

Which is faster, Codestral 25.01 or Grok 3?

Codestral 25.01 has the lower time-to-first-token (150 ms vs 250 ms). Tokens/sec is a separate column if you care about long completions.

Which has the larger context window?

Codestral 25.01 accepts 256k tokens versus 131k.

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. Codestral 25.01 and Grok 3 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
