Software
The Supernova inference cloud
A drop-in inference service for open models. Point your workload at our API and serve the same models far below standard cost — we keep the KV cache resident on cheap NAND and optimise the whole memory hierarchy for you. Strongest exactly where it hurts most: long context, high batch, and agent workloads.
- Lower cost per token on open models — GLM-5.3, GLM-5.3 Fast and GLM-5.2 today, more on the way

GLM-5.3 Fast
GLM-5.3 in fp4 on a faster lane — higher throughput and priority scheduling for latency-sensitive agents and interactive coding.

GLM-5.2
The previous GLM generation, served in fp8 at the same rate as GLM-5.3 — for workloads already tuned to 5.2 or that need a stable target.
