This page compares GPT-5 (OpenAI) and Qwen 2.5 Coder 32B (Alibaba) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, GPT-5 is ahead by 133 points (1,558 vs 1,425; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, GPT-5 resolves 68.4% versus 65.2% (seed-bootstrap (Aug 1, 2026)). Qwen 2.5 Coder 32B streams faster (110 tok/s) while Qwen 2.5 Coder 32B is the cheaper output token ($0.72/1M). GPT-5 has the larger context window (400k tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

Frequently Asked Questions

Which is better overall, GPT-5 or Qwen 2.5 Coder 32B?: GPT-5 has the higher preference Elo in our latest snapshot (1,558). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, GPT-5 or Qwen 2.5 Coder 32B?: GPT-5 leads SWE-bench at 68.4% vs 65.2%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: Qwen 2.5 Coder 32B output tokens are $0.72/1M versus $10/1M. Input prices and retry rates still move the real bill.
Which is faster, GPT-5 or Qwen 2.5 Coder 32B?: Qwen 2.5 Coder 32B has the lower time-to-first-token (180 ms vs 290 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: GPT-5 accepts 400k tokens versus 131k.
Can I self-host either model?: Qwen 2.5 Coder 32B 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-5 and Qwen 2.5 Coder 32B Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
