https://swelljoe.com/post/will-it-mythos/: "Poor performer here, only found the one bug that almost every model found, despite its performance on other benchmarks being excellent for its size. […] It also performs poorly in a chat without tools, exhibiting an ehthusiasm for hallucination. I’m currently working on a replication of this with full tool access, including bash/Python, which may allow this model to be competitive."

Can anyone explain what’s the story here? Is this just a re-skinned qwen? Who is deepreinforce-ai and why isn’t this model listed on their website?

How does it self-improve, does the model change on disk - or just during a single context run it gets better?

It doesn't self-improve, that's a misleading headline.

As far as I can tell they trained it by running their own reinforcement learning on top of Qwen and Gemma 4 (not sure how they combined weights from both, or if they used Qwen as the basis and Gemma 4 to help train?) - so the "self-improving" is about their training process, not how you use the weights.

Looking at the models weights, they seem to be Qwen fine tunes with the 31b being a Gemma 4 fine tune

Gotcha. That makes more sense. We ran the model to train the model -> “self-improving”.

Yes, it's "another post-train of Qwen 3.5/3.6 MoE intended for agentic use", according to https://swelljoe.com/post/will-it-mythos/.
