Frequently Asked Questions

Which is better overall, Body Builder (beta) or Claude 3.5 Sonnet?: 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, Body Builder (beta) or Claude 3.5 Sonnet?: 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?: Body Builder (beta) output tokens are $-1,000,000/1M versus $15/1M. Input prices and retry rates still move the real bill.
Which is faster, Body Builder (beta) or Claude 3.5 Sonnet?: We do not have TTFT for both models.
Which has the larger context window?: Claude 3.5 Sonnet accepts 200k tokens versus 128k.
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. Body Builder (beta) and Claude 3.5 Sonnet Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
