# StreamLake > Kuaishou's AI cloud, home of the KAT-Coder agentic coding models. Canonical: https://www.subconscious.dev/providers/streamlake · By The Subconscious Team · Updated September 30, 2026 - Founded: brand launched around 2024 (Kuaishou dates to 2011) - Example models: KAT-Coder-Pro V2.5, KAT-Coder-Air - Website: https://www.streamlake.ai ## Overview 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. The headline model is KAT-Coder-Pro V2.5, a proprietary agentic coding model from Kuaishou's KwaiKAT team. StreamLake says large-scale agentic reinforcement learning trained it to handle repository-level work: reading an issue, finding changes across files, running tests and fixing its own errors over long runs. Developers can pay per token or buy a KwaiKAT Coding Plan, and both come with OpenAI-protocol endpoints plus a Claude-protocol proxy that drops into Claude Code or OpenClaw. Earlier KAT-Coder versions spread through resellers like 302.AI and OpenRouter. ## Upsides - Direct access to Kuaishou's in-house coding model, with a Claude Code-compatible endpoint. - Backed by a large company with hyperscale video infrastructure. ## Core use cases - Low-cost agentic coding through a subscription plan. - Chinese internet businesses that want domestic MaaS and bare-metal capacity. ## Downsides - Pricing and much of the documentation lead with China and yuan, which complicates Western procurement. - Data residency in China rules it out for many US and EU enterprise buyers. ## At a glance | Attribute | Value | |---|---| | Model access | Proprietary coding models | | Flagship models | KAT-Coder-Pro V2.5, KAT-Coder-Air | | Speed | - | | Price | Per token or KwaiKAT Coding Plan | | Customization | - | | Deployment | MaaS API, bare metal | | Long context | - | ## FAQ ### What is StreamLake?
