Tencent Hy4 integration just landed in OpenClaw. This is Tencent Hunyuan's latest model with vision support, 1M-token context window, and notably better coding + long-horizon agent performance.

Context window at 1M tokens puts it in the same league as Gemini 1.5 Pro for handling massive codebases or multi-turn agent workflows. The agent improvements matter—most models still struggle with multi-step reasoning that requires maintaining state across dozens of tool calls.

Accessible via Tencent TokenHub, TokenPlan, and $OpenRouter. If you're building agents that need to hold context across extended sessions or process large repos, this is worth testing against Claude/GPT-4 benchmarks.
