Tencent: Hy3 preview (free)
Analysis Summary
Tencent Hy3 preview is a free model released in April 2026, with a 262,144-token context window, tool use, and function calling. Its intelligence index is 41.9 and agentic index is 63.4, alongside strong GPQA and long-context results. The coding index is 36.5, so its strongest supplied evidence is for reasoning and agent-style execution rather than top-tier software engineering.
The profile makes it a promising candidate for research, document-heavy workflows, and automation that depends on tools. Its preview status is a practical limitation: teams should validate stability and behavior before placing it on a critical client workflow. Free access supports low-cost evaluation and potentially high-volume use, but does not remove the need for review on consequential outputs. Test its function-calling behavior and failure recovery before allowing autonomous actions.
