Frequently Asked Questions

Which is better overall, Anthropic: Claude Opus 4.5 (batch) or Llama 4 Scout?
We do not have preference Elo for both models, so we do not declare an overall winner. Compare the metrics that exist.
Which is better at coding, Anthropic: Claude Opus 4.5 (batch) or Llama 4 Scout?
SWE-bench is missing for at least one model, so we do not rank coding from a single number.
Which is cheaper to run in production?
Llama 4 Scout output tokens are $0.3/1M versus $12.5/1M. Input prices and retry rates still move the real bill.
Which is faster, Anthropic: Claude Opus 4.5 (batch) or Llama 4 Scout?
We do not have TTFT for both models.
Which has the larger context window?
Llama 4 Scout accepts 1.3M tokens versus 200k.
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. Anthropic: Claude Opus 4.5 (batch) and Llama 4 Scout Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
