Tencent

2 models built

Tencent is the Shenzhen conglomerate behind WeChat, and its Hunyuan family covers language, video, and 3D generation models. On OpenKey you get two text models from that lineup: Hunyuan A13B Instruct and the newer Hy3 preview. Both are recent — A13B Instruct shipped July 2025, Hy3 preview followed in April 2026 — and both push large context windows (131,072 and 262,144 tokens respectively), which fits Tencent's pattern of building for long-document and long-conversation use cases rather than chasing benchmark headlines. Founded in 1998, Tencent runs Hunyuan as one arm of a much larger consumer and infrastructure business.

Lineup

With only two models, the choice comes down to context length and price. Hunyuan A13B Instruct costs $0.14 per 1M input tokens and $0.57 per 1M output tokens (OpenKey: $0.1442 in / $0.5871 out after the 3% fee), with a 131,072-token context window. Hy3 preview is cheaper on both ends — $0.063 input and $0.21 output per 1M tokens (OpenKey: $0.0649 in / $0.2163 out) — and doubles the context to 262,144 tokens. Unless you specifically need A13B Instruct's instruction-tuned behavior, Hy3 preview is the better default: lower cost and more room for long inputs.
