Nebius vs StreamLake: key differences
StreamLake is the AI cloud of Kuaishou, and its headline product is a proprietary agentic coding model, KAT-Coder-Pro V2.5, sold per token or through a KwaiKAT Coding Plan with a Claude-protocol proxy for Claude Code. Nebius is a neutral host: open models from many labs through Token Factory, dedicated endpoints, uploaded fine-tunes and raw GPUs. Both sell bare-metal style compute, but StreamLake's is pitched at Chinese internet businesses and Nebius's at European and global buyers. Kuaishou built that infrastructure to serve short video at massive scale.
Residency is the sharpest difference. StreamLake's data sits in China, which complicates Western procurement. Nebius offers EU or US placement and is backed by capacity deals with Microsoft and Meta. The case for StreamLake is the model itself: direct access to Kuaishou's in-house coder on a subscription plan, trained with agentic reinforcement learning for repository-level work. The case for Nebius is choice and control across open models, plus the option to fine-tune and serve your own.
What Nebius and StreamLake do
Nebius
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

StreamLake is the AI cloud brand of Kuaishou, the Chinese short-video company behind the Kling video models. It sells model-as-a-service inference and bare-metal compute to internet businesses, drawing on the infrastructure Kuaishou built to serve video at massive scale. Its developer site offers APIs, SDKs and integration guides aimed at taking teams from testing to production, and its Vanchin platform also hosts third-party open models from DeepSeek and GLM, most recently DeepSeek V4.1 Flash 1017.
Example models: KAT-Coder-Pro V2.5, KAT-Coder-Air V2.5
