1/8 Looped transformers are coming.
OpenMythos, recurrent-depth architectures, weight recycling — the frontier labs are all exploring this.
But here's what nobody's talking about: the hardware implications are massive.
Let me break it down. 🧵
Introducing OpenMythos
An open-source, first-principles theoretical reconstruction of Claude Mythos, implemented in PyTorch.
The architecture instantiates a looped transformer with a Mixture-of-Experts (MoE) routing mechanism, enabling iterative depth via weight sharing and conditional computation across experts.
My implementation explores the hypothesis that recursive application of a fixed parameterized block, coupled with sparse expert activation, can yield improved efficiency–performance tradeoffs and emergent multi-step reasoning.

Such a big deal. Alternatives are @UnslothAI and @axolotl_ai
Introducing Trellis for Kimi K2 Thinking.
It's post-training code that's 50x faster than the best single-node open-source version and 2x cheaper than training APIs.
After safety testing, we're open-sourcing it, giving builders the best tools to customize a frontier model.

Curious to see whether they will release medium-size models to compete with Alibaba Qwen3.5 series
Finally, V4 is coming
* Set to release next week ahead of the Two Sessions
* Optimised for Chinese chips led by Huawei and Cambricon
* Multi-modal and early tests results are “impressive”
Exclusive: DeepSeek to release long-awaited AI model

This is a fantastic playbook for autoscaling inference of multiple LLMs with Ray and vLLM. vLLM by itself can only serve one model per process.
