Frequently Asked Questions

Which is better overall, Ernie 4.5 Turbo or Gemini 2.5 Flash?
Ernie 4.5 Turbo has the higher preference Elo in our latest snapshot (1,450). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Ernie 4.5 Turbo or Gemini 2.5 Flash?
Ernie 4.5 Turbo leads SWE-bench at 57% vs 48%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?
Gemini 2.5 Flash output tokens are $0.4/1M versus $1.2/1M. Input prices and retry rates still move the real bill.
Which is faster, Ernie 4.5 Turbo or Gemini 2.5 Flash?
Gemini 2.5 Flash has the lower time-to-first-token (110 ms vs 200 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?
Gemini 2.5 Flash accepts 1M 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. Ernie 4.5 Turbo and Gemini 2.5 Flash Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
