Models / Open weights
Power reasoning, tool use, and long-running agent workloads through OpenAI- and Anthropic-compatible APIs.
01 / Model catalog
Access models from the top open-source labs through a single, unified Inference API. Pay only for the tokens you use.
GLM-5.3
prism/glm-5.3
Z.AI’s strongest GLM-5 agentic coder — the same base as GLM-5.2, with every gain coming from post-training.

02 / Production workloads
Prism serves open-weight models through one reliable inference API built for long tool traces, large context windows, and production-scale agent workloads.
Speculative decoding and batching shaped around code generation, not general chat.
Batched serving across a GPU fleet so a customer agent can stay in a tight loop.
Redundant serving paths keep inference available when individual workers or GPUs go offline.
