Hy3

by Tencent

All Tencent releases

Hy3 is the third generation of Tencent's Hunyuan line, released in July 2026 under a fully permissive Apache 2.0 license with no geographic carve-outs. That last detail matters, because the April preview of the same family had excluded the EU, UK and South Korea from its terms, and the full release removed those restrictions. Architecturally it is a Mixture-of-Experts with 295 billion total parameters and roughly 21 billion active for any given token, so serving cost tracks a far smaller model than the headline count suggests. It carries a 256K token context window and a hybrid reasoning system that moves between fast and slow modes by task, and the weights are published on Hugging Face, ModelScope and GitHub in both BF16 and FP8 formats, which suits self-hosted agentic coding and reasoning work.

Uptime and availability

One of Hy3's 2 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.

100%route uptime, last 30 days

Its other routes aren't measured here yet.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 1 further route is not on the board yet. See uptime for every provider Opper monitors.

Data handling per route

Each route hosting Hy3 has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
