GLM-5.3
GLM · Released 2026-08-14
Z.ai's August 2026 coding refresh of the GLM-5.2 base. API list price $1.40 / $4.40 per 1M tokens — same slot as GLM-5.2.
Current Z.ai coding-plan and API model for long-horizon agent work. Prefer sourced ledger rows over vendor coding/cyber tables; AA scores sync from the public snapshot. Open weights were promised after a safety delay, not at launch.

Editor's note
Same base as GLM-5.2; gains are post-training. Vendor Terminal Bench / Z.ai Code Bench / cyber figures stay off the ledger until they appear in a mapped source. Editorial depth still needs a desk pass.Benchmark placements
Per-benchmark positions
Where GLM-5.3 places on each public benchmark source that publishes a row. Rank counts every model with a latest row in the same test — not a universal quality score.
