Florian Brand, Research Engineer at Prime Intellect, posted that the model is not slop and avoids deepfried textual outputs. He noted it latches onto technical details without immediate token vomit on screen. Brand added that its reasoning trails by about one generation, making responses verbose and token-heavy, yet more engaging to read. He called the full version a potential top-three open model contender. The posts reference a Tencent Hy4 Preview release described elsewhere as a 770B-A49B MoE model with 1 million token context and Apache 2.0 license.
