Frequently Asked Questions

Which is better overall, Claude Opus 4.5 or DeepSeek: R1 Distill Llama 70B?
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, Claude Opus 4.5 or DeepSeek: R1 Distill Llama 70B?
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?
DeepSeek: R1 Distill Llama 70B output tokens are $0.8/1M versus $25/1M. Input prices and retry rates still move the real bill.
Which is faster, Claude Opus 4.5 or DeepSeek: R1 Distill Llama 70B?
We do not have TTFT for both models.
Which has the larger context window?
Claude Opus 4.5 accepts 200k tokens versus 8k.
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 4.5 and DeepSeek: R1 Distill Llama 70B Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
