GLM-5.2: Benchmarks, Pricing & Context Window
GLM-5.2 is a language model from ZAI, released in June 2026, with a 1.0M-token context window, and pricing from $0.750/M input, $0.140/M cached input, $2.40/M output.
GLM-5.2 is Z.AI's flagship foundation model built for long-horizon tasks, delivering a solid 1M-token context that stably sustains long, messy coding-agent trajectories. It improves substantially over GLM-5.1, becoming the strongest
