Frequently Asked Questions

Which is better overall, MoonshotAI: Kimi K2.5 or Llama 4 Scout?: MoonshotAI: Kimi K2.5 has the higher preference Elo in our latest snapshot (1,515). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, MoonshotAI: Kimi K2.5 or Llama 4 Scout?: MoonshotAI: Kimi K2.5 leads SWE-bench at 71.3% vs 52.4%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: Llama 4 Scout output tokens are $0.3/1M versus $2.85/1M. Input prices and retry rates still move the real bill.
Which is faster, MoonshotAI: Kimi K2.5 or Llama 4 Scout?: Llama 4 Scout has the lower time-to-first-token (130 ms vs 270 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Llama 4 Scout accepts 1.3M tokens versus 262k.
Can I self-host either model?: Llama 4 Scout 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. MoonshotAI: Kimi K2.5 and Llama 4 Scout Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
