Tencent: Hy3 (free) now available on OpenRouter (262k context, $0.00/M in, $0.00/M out)
TL;DR
Tencent's Hy3, a 295B-parameter MoE model with 21B active parameters, launches free on OpenRouter with 262k context.
What changed
Tencent's Hy3 model is now offered free on OpenRouter with 262k context. Developers access its Mixture-of-Experts setup for reasoning tasks while Basic Users run queries at no cost. Vibe Builders apply the configurable effort levels in their agentic setups.
Why it matters
Developers gain a 21B active parameter option for production agentic workflows using the full 262k context window. This zero-cost entry lets Vibe Builders test real-world use cases against paid MoE alternatives that charge per million tokens. Basic Users explore the same routing features without budget limits.
What to watch for
Compare outputs against the standard paid Hy3 variant on the same platform. Developers should verify token usage directly in the OpenRouter console after a 10k context test run.
Who this matters for
- Vibe Builders: Test complex agentic workflows for free using the 262k context window and MoE reasoning.
Amy’s take
Tencent is aggressive with the Hy3 release on OpenRouter. Offering a 295B parameter MoE model for free is a direct shot at established frontier models. The 21B active parameter count suggests high efficiency for the performance tier, making it a prime candidate for long-context agentic tasks.
Operators should jump on this immediately. Free access to a 262k context window allows for massive document ingestion and complex state management without the usual token anxiety. While free tiers often imply rate limits or lower priority, the technical specs here are robust enough for serious prototyping.
Use this to benchmark your current RAG pipelines against a high-expert MoE architecture.
