DeepSeek V4.1 Flash Runs on One 5090

An independent llama.cpp fork runs DeepSeek-V4.1-Flash on one RTX 5090 paired with 125.7GB of RAM and disk offload. The 552B MoE model reaches 5.12 tokens per second on cold content and 21.27 tokens per second with resident weights.

// ANALYSIS

–DeepSeek’s 8B prefill and 16B decode activation, plus a KV cache roughly one-quarter the size of the previous model’s, make the architecture unusually efficient for its scale.

Schmidt Sciences drops GlossoGen agent language platform

GlossoGen is an open-source simulation platform developed by researchers from Schmidt Sciences, UT Austin, the University of Edinburgh, and AE Studio to study emergent communication in multi-agent LLM teams. Experiments demonstrate that under communication pressure, agent populations spontaneously develop novel, compositional languages that optimize task efficiency while rapidly bypassing human comprehension.
