Frequently Asked Questions

Which is better overall, Claude Opus 4.5 or Krea 2 Medium Turbo?
We do not have preference Elo for both models, so we do not declare an overall winner. Compare the metrics that exist.
Which is better at coding, Claude Opus 4.5 or Krea 2 Medium Turbo?
SWE-bench is missing for at least one model, so we do not rank coding from a single number.
Which is cheaper to run in production?
List prices are missing for at least one model.
Which is faster, Claude Opus 4.5 or Krea 2 Medium Turbo?
We do not have TTFT for both models.
Which has the larger context window?
Context window is missing for at least one model.
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. Claude Opus 4.5 and Krea 2 Medium Turbo Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
