## How they compare

Z.ai makes GLM, and Crusoe hosts GLM 5.3, so the comparison is between the lab and a host. Z.ai lists GLM-5.3 at $1.40 in and $4.40 out per million with cached input at $0.26 and a 1M context, and GLM-5.3-Flash at $0.075 in and $0.25 out. Several older Flash models cost nothing. Crusoe's serverless range starts at $0.05 in and tops out at $1.74 in and $4.40 out, across DeepSeek, GLM, Kimi, Gemma, gpt-oss and Nemotron, with cached input billed well below list through its cluster-wide KV cache. GLM-5.3 runs about 80 tokens per second on Z.ai. Crusoe's speed claim is up to 9.9x faster time to first token versus vLLM on prefix-heavy work.

Z.ai's pull is the GLM Coding Plan. For $18 a month on Lite, developers get a quota that resets every five hours and weekly, and an Anthropic-compatible endpoint runs Claude Code on GLM with a few environment variables. The trade-offs are location and throttling: servers sit mostly in China, adding 100 to 200ms from the US or Europe, and quota burns 2 to 3x faster on premium models during Beijing peak hours. Crusoe offers an OpenAI-compatible API, LoRA fine-tuning, dedicated endpoints with SLAs and raw GPUs. Since GLM ships under MIT, a fine-tune on Crusoe carries no license limits. Pick Z.ai for cheap flat-rate coding, and Crusoe for GLM in production with dedicated capacity and customization.

## What each one does

### Z.ai

Z.AI is the international brand of Chinese lab Zhipu AI, maker of the GLM models. Its current flagship, GLM-5.3, shipped August 17, 2026 at $1.40 in and $4.40 out per million tokens, with cached input at $0.26. GLM-5.3-Flash costs $0.075 in and $0.25 out, and several older Flash models are priced at zero, a real free tier instead of trial credits. GLM-5, released in February 2026, is a 744B mixture-of-experts model under an MIT license, and at launch it ranked first among open-weight models on the Artificial Analysis index with a record-low hallucination score.

### Crusoe

Crusoe started in 2018 turning wasted natural gas into power for computing and has since become a vertically integrated AI infrastructure company: it sources energy, builds data centers and rents GPUs through Crusoe Cloud. It designed and built the Abilene, Texas campus behind the OpenAI and Oracle Stargate project, planned at 1.2 GW, and in March 2026 announced an adjacent 900 MW campus for Microsoft. On September 17, 2026 it closed the first part of a $3.9B Series F at a $30.9B post-money valuation, and it reports over 6 GW of contracted capacity. Crusoe Cloud lists GB200 NVL72, B200 and AMD MI355X by quote, with H100 at $3.90 and H200 at $4.29 per GPU-hour on demand.
