What happened
Tencent released Hy3, a 295B-parameter Mixture-of-Experts model (21B active) under Apache 2.0, with 256K context length. It reportedly rivals flagship open-source models with 2-5x more parameters and is available free on OpenRouter until July 21st. Simon Willison tested it on an SVG generation task and noted it performed well.
Why it matters
A strong Apache 2.0 MoE model from a major Chinese tech player adds another viable open-weight option for builders experimenting with self-hosted or API-accessible LLMs. The free OpenRouter window is a low-friction way to benchmark it against current favorites before committing. For Malaysian builders, more competition in open-weight models means more leverage on cost and deployment flexibility, especially for those exploring local inference or multi-provider setups.
Discussion angle
Compare Hy3's SVG/code generation quality and cost profile against current go-to models like Claude or DeepSeek, and discuss whether the Apache 2.0 license plus MoE efficiency makes it worth integrating into agent pipelines or self-hosted stacks.
