StreamLake vs RunInfra: key differences
Both sell cheap subscriptions that plug coding agents into their models. StreamLake's KwaiKAT Coding Plan runs KAT-Coder-Pro V2.5, a proprietary model StreamLake says was trained for repository-level work over long runs, through OpenAI-protocol endpoints and a Claude-protocol proxy for Claude Code. RunInfra's coding plans start at $10 a month with limits that reset every five hours and weekly, and run mid-size open models like Nemotron 3.5 Lightning 30B and Qwen 3.8 27B across Claude Code, Codex, OpenCode, Cline and Aider.
Past the plans, their businesses differ. StreamLake is Kuaishou's AI cloud and sells model-as-a-service and bare-metal compute to internet businesses, mostly in China, where its data resides. That residency, plus yuan-first pricing, complicates Western procurement. RunInfra is a young company with little independent benchmarking, and its library sits far from frontier quality, but it offers an agent that benchmarks and deploys a tuned model for you, plus uploads up to 50 GB and voice pipelines. Western solo developers lean toward RunInfra. Chinese teams lean toward StreamLake.
What StreamLake and RunInfra do
StreamLake
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.
Example models: KAT-Coder-Pro V2.5, KAT-Coder-Air
Full StreamLake profileRunInfra
RunInfra pitches open models built for agents, with two ways in. Its hosted Model APIs serve a small curated library, including Nemotron 3.5 Lightning 30B, Qwen 3.8 27B and Ornith 1.5 35B, behind one key that works with both the OpenAI and Anthropic SDKs. Cached context bills at a discount. Coding plans start at $10 a month with limits that reset every five hours and every week, and they plug into Claude Code, Codex, OpenCode, Cline, Aider and dozens of other agent CLIs.
Example models: Nemotron 3.5 Lightning 30B, Qwen 3.8 27B

Running long-horizon agents?
If your agents run past 200K tokens, compare both against Subconscious. Our inference stack treats a long-horizon trace as the primary workload, so speed, cost, and accuracy hold up deep into the trace.
