Frequently Asked Questions

Which is better overall, GPT-4.5 Orion or MiniMax M2.5?
GPT-4.5 Orion has the higher preference Elo in our latest snapshot (1,540). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, GPT-4.5 Orion or MiniMax M2.5?
MiniMax M2.5 leads SWE-bench at 75.8% vs 71%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?
MiniMax M2.5 output tokens are $0.9/1M versus $150/1M. Input prices and retry rates still move the real bill.
Which is faster, GPT-4.5 Orion or MiniMax M2.5?
MiniMax M2.5 has the lower time-to-first-token (250 ms vs 350 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?
MiniMax M2.5 accepts 205k tokens versus 128k.
Can I self-host either model?
MiniMax M2.5 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. GPT-4.5 Orion and MiniMax M2.5 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
