Z.ai vs Nebius: key differences
GLM is available from both, which makes this a question of where and how. Z.ai, the model's maker, serves GLM-5.3 at $1.40 in and $4.40 out, with cached input at $0.26, a free tier on older Flash models and the GLM Coding Plan from $18 a month. Its servers sit mostly in China, which adds 100 to 200ms from the US or Europe and raises data concerns for enterprises. Nebius lists GLM among 60+ open models in its Token Factory, with dedicated endpoints that offer EU or US placement and a 99.9% SLA. Its listing does not say which GLM versions it carries.
Nebius is also a full AI cloud. It sells raw NVIDIA GPUs, from H100s at $4.50 an hour on demand, or from $0.79 on spot, up to GB300 NVL72 racks, and it serves uploaded fine-tunes at the same token pricing. Since GLM weights are open, a team can fine-tune GLM and host it on Nebius. Nebius has no free trial and a $25 minimum first payment, while Z.ai's free Flash models cost nothing to try. For a European enterprise, Nebius is the safer route to GLM. For an individual developer coding on a budget, Z.ai's plan is hard to beat.
What Z.ai and Nebius do
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. Its weights came out August 28 under a custom GLM-5.3 License that requires a security review for hosts with more than $10B in yearly revenue. GLM-5.3-Flash, a 320B multimodal model with 18B active, costs $0.15 in and $0.50 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.
Example models: GLM-5.3, GLM-5.3-Flash
Full Z.ai profileNebius
Nebius is an Amsterdam-headquartered AI cloud and the strongest European alternative to the US hyperscalers. It sells raw NVIDIA GPU compute, from H100s at $4.50 an hour on demand or from $0.79 on dynamic spot pricing, up to GB300 NVL72 racks, and it has begun adding Vera Rubin. On-demand GPU prices rose on October 1, 2026, and preemptible VMs moved to demand-set spot prices on October 8. Hyperscale buyers back it: a Microsoft capacity deal worth about $17.4B in September 2025, then a Meta agreement worth up to about $27B in March 2026.
Example models: DeepSeek V4 Pro, Kimi K3, MiniMax M3
