Frequently Asked Questions

Which is better overall, Claude Opus 5 or DeepSeek R1?: Claude Opus 5 has the higher preference Elo in our latest snapshot (1,624). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Claude Opus 5 or DeepSeek R1?: Claude Opus 5 leads SWE-bench at 79.2% vs 65.2%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: DeepSeek R1 output tokens are $2.5/1M versus $50/1M. Input prices and retry rates still move the real bill.
Which is faster, Claude Opus 5 or DeepSeek R1?: Claude Opus 5 has the lower time-to-first-token (310 ms vs 420 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Claude Opus 5 accepts 1M tokens versus 64k.
Can I self-host either model?: DeepSeek R1 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 Opus 5 and DeepSeek R1 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
