This page compares Gemini 1.5 Pro (Google) and GLM-5.2 (Zhipu) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, GLM-5.2 is ahead by 232 points (1,492 vs 1,260; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, GLM-5.2 resolves 69.3% versus 38% (seed-bootstrap (Aug 1, 2026)). GLM-5.2 streams faster (84 tok/s) while GLM-5.2 is the cheaper output token ($0.97/1M). Gemini 1.5 Pro has the larger context window (2M 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, Gemini 1.5 Pro or GLM-5.2?: GLM-5.2 has the higher preference Elo in our latest snapshot (1,492). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Gemini 1.5 Pro or GLM-5.2?: GLM-5.2 leads SWE-bench at 69.3% vs 38%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: GLM-5.2 output tokens are $0.97/1M versus $5/1M. Input prices and retry rates still move the real bill.
Which is faster, Gemini 1.5 Pro or GLM-5.2?: Gemini 1.5 Pro has the lower time-to-first-token (240 ms vs 270 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Gemini 1.5 Pro accepts 2M tokens versus 1M.
Can I self-host either model?: GLM-5.2 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. Gemini 1.5 Pro and GLM-5.2 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
