Frequently Asked Questions

Which is better overall, GPT-5.6 Sol or OpenAI o1-mini?: GPT-5.6 Sol has the higher preference Elo in our latest snapshot (1,608). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, GPT-5.6 Sol or OpenAI o1-mini?: GPT-5.6 Sol leads SWE-bench at 77.6% vs 56.4%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: OpenAI o1-mini output tokens are $4.4/1M versus $30/1M. Input prices and retry rates still move the real bill.
Which is faster, GPT-5.6 Sol or OpenAI o1-mini?: GPT-5.6 Sol has the lower time-to-first-token (270 ms vs 280 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: GPT-5.6 Sol accepts 1.1M 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-5.6 Sol and OpenAI o1-mini Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
