Z.AI: GLM 5.3 PrimeActive

z-ai/glm-5.3-prime

GLM-5.3-Prime is the high-speed variant of Z.ai's GLM-5.3, inheriting its full capabilities while delivering 1.5–2× higher output throughput through inference acceleration. It supports text input and output with a 1M-token context window and up to 128K output tokens, and is optimized for coding and agentic workloads, including long-horizon multi-turn agent orchestration, real-time conversation, and streaming code generation.
