In the real leaderboard data, HY3 (free) scores 82.9 and Nemotron 3 Ultra (free) scores 81.7, both provided by opencode-zen.
Among model choices, GLM-5.2 is the second-best option with stable overall performance, HY3 is suited for simple webpages, and the Auto default mode is not recommended because it may randomly select models and cause unstable output.
The instructor used Tencent's Work Buddy tool paired with the free HY3 model to live-demonstrate the complete FDE delivery process, producing an FDE position radar page that integrated 28 JD requirements from four major companies with real-time audience voting data.
During the live demo, the free HY3 model struggled in the self-testing and fault-finding segment, failing to produce output for an extended period before the instructor intervened, illustrating that different AI tools vary significantly in capability and that real work requires flexible switching among tools such as Claude Code, Codex, Trae, and Work Buddy.
WorkBuddy has a built-in membership model HY3, which is currently in a free trial phase.
