Frequently Asked Questions

Which is better overall, GPT-4.5 Orion or OpenAI: o1-pro (batch)?: 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, GPT-4.5 Orion or OpenAI: o1-pro (batch)?: 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?: GPT-4.5 Orion output tokens are $150/1M versus $300/1M. Input prices and retry rates still move the real bill.
Which is faster, GPT-4.5 Orion or OpenAI: o1-pro (batch)?: We do not have TTFT for both models.
Which has the larger context window?: OpenAI: o1-pro (batch) accepts 200k 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. GPT-4.5 Orion and OpenAI: o1-pro (batch) Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
