Frequently Asked Questions

Which is better overall, Claude Opus 4 or Gemini 1.5 Pro?
Claude Opus 4 has the higher preference Elo in our latest snapshot (1,490). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Claude Opus 4 or Gemini 1.5 Pro?
Claude Opus 4 leads SWE-bench at 72.5% vs 38%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?
Gemini 1.5 Pro output tokens are $5/1M versus $75/1M. Input prices and retry rates still move the real bill.
Which is faster, Claude Opus 4 or Gemini 1.5 Pro?
Gemini 1.5 Pro has the lower time-to-first-token (240 ms vs 390 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?
Gemini 1.5 Pro accepts 2M tokens versus 200k.
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 and Gemini 1.5 Pro Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
