Frequently Asked Questions

Which is better overall, Claude 3.7 Sonnet or DeepSeek Coder V2?: DeepSeek Coder V2 has the higher preference Elo in our latest snapshot (1,365). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Claude 3.7 Sonnet or DeepSeek Coder V2?: Claude 3.7 Sonnet leads SWE-bench at 70.3% vs 60.5%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: DeepSeek Coder V2 output tokens are $0.28/1M versus $15/1M. Input prices and retry rates still move the real bill.
Which is faster, Claude 3.7 Sonnet or DeepSeek Coder V2?: Claude 3.7 Sonnet has the lower time-to-first-token (240 ms vs 290 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Claude 3.7 Sonnet accepts 200k tokens versus 128k.
Can I self-host either model?: DeepSeek Coder V2 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. Claude 3.7 Sonnet and DeepSeek Coder V2 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
