Kuaishou’s StreamLake Unveils Full AI-Coding Ecosystem

Kuaishou Technology, through its enterprise technology arm StreamLake, has officially entered the AI coding market with a comprehensive “tools + models + platform” product suite designed to redefine intelligent software development.

The new ecosystem includes three core components:

• CodeFlicker — an intelligent development tool serving as an AI coding companion. It offers two modes, Jam and Duet, supporting real-time code generation, design-to-code conversion, one-click deployment, and full DevOps workflows.
• KAT-Coder — a family of AI coding models featuring Pro V1 (enterprise), Air V1 (lightweight, free for all users), and Exp-72B-1010 (academic open-source). The Pro V1 model achieved a 73.4% problem-solving rate on the SWE-Bench Verified benchmark, outperforming leading competitors.
• WanQing (Vanchin) Platform — a high-availability large-model hosting platform (99.95% SLA) with Level-3 cybersecurity certification. It supports mainstream models including DeepSeek, Qwen, and Kimi, enabling large-scale enterprise deployments.

Strategic Move Beyond Social Media

The launch marks Kuaishou’s strategic expansion beyond its short-video and live-streaming roots into enterprise AI infrastructure and developer tools. By integrating intelligent coding assistants, foundational models, and secure hosting into a unified ecosystem, StreamLake aims to address the growing demand for AI-driven software engineering solutions among enterprises and developers.

Industry analysts view this as part of a broader trend among major Chinese tech firms investing heavily in vertical AI ecosystems—moving from consumer applications toward full-stack industrial intelligence.

Outlook

With its new AI coding matrix, Kuaishou positions StreamLake as a credible challenger in the global AI-developer tools space. The company expects the ecosystem to lower coding barriers, boost productivity, and accelerate digital transformation across multiple industries.
