This page compares DeepSeek Coder V2 (DeepSeek) and GLM-5.3 (Zhipu) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, GLM-5.3 is ahead by 193 points (1,558 vs 1,365; seed-bootstrap (Aug 16, 2026)). On SWE-bench coding, GLM-5.3 resolves 76.4% versus 60.5% (seed-bootstrap (Aug 16, 2026)). GLM-5.3 streams faster (90 tok/s) while DeepSeek Coder V2 is the cheaper output token ($0.28/1M). GLM-5.3 has the larger context window (200k 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, DeepSeek Coder V2 or GLM-5.3?: GLM-5.3 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, DeepSeek Coder V2 or GLM-5.3?: GLM-5.3 leads SWE-bench at 76.4% vs 60.5%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: DeepSeek Coder V2 output tokens are $0.28/1M versus $1.8/1M. Input prices and retry rates still move the real bill.
Which is faster, DeepSeek Coder V2 or GLM-5.3?: GLM-5.3 has the lower time-to-first-token (255 ms vs 290 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: GLM-5.3 accepts 200k tokens versus 128k.
Can I self-host either model?: DeepSeek Coder V2 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. DeepSeek Coder V2 and GLM-5.3 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
