About GLM-5.3 Prime

GLM-5.3-Prime is the high-speed variant of GLM-5.3, inheriting its full capabilities while achieving 1.5–2× the output TPS through inference acceleration. It delivers state-of-the-art coding and agentic performance among open-source models, supports 1M context and 128K output tokens, and can produce production-grade results end-to-end — along with emergent cybersecurity capabilities such as vulnerability discovery. Designed for latency-sensitive scenarios including real-time conversation, multi-turn agent orchestration, and streaming code generation.

GLM-5.3 Prime is a chat model by Z.ai, available on Eden AI through 1 endpoint from 1 provider, from $1.82 per million input tokens and $5.72 per million output tokens, with a context window of up to 1M tokens.
