Drew Breunig's nesformer project bakes a working Nintendo Entertainment System 6502 CPU emulator into the weights of Qwen3.5-4B, allowing NES ROMs like Super Mario Bros to run (slowly) inside the model. Inspired by Divyansh Agrawal's qwenputer and built with Opus 5.5 prompts, it uses Christopher Pow's decade-old nestest conformance suite for validation.

据The Information报道，OpenAI的Astra模型已成为中国AI实验室的首要蒸馏目标，Moonshot AI在开发Kimi K3.1 Pro时蒸馏了Astra，DeepSeek的V4.1-Flash升级版也受益于对Astra的蒸馏，此前Claude模型曾是中国实验室的主要蒸馏对象。

Qwenputer is an experimental Qwen 3.5 4B model with a fully functioning, deterministic RISC-V CPU compiled into its weights, using the model's own Gated DeltaNet layers as exact RAM to run arithmetic, C and MicroPython entirely within forward passes — no tools or external runtime needed.

有人在Qwen模型权重中直接构建了一台32位RISC-V CPU，使其能够在模型内部执行指令，这可能对工具调用和计算机操作能力产生影响。

A new Google DeepMind paper, SkillSmith, treats prefix key-value caches as an input modality, composing textual knowledge and existing weights into a fresh prefix cache for a frozen Gemma 3 4B model at inference time, improving adaptation without a target-specific training run.

Google DeepMind introduces SkillSmith, which treats model weights as an additional modality that LLMs can natively reason over, enabling instruction-steered parametric synthesis for composing skills at inference time. The approach outperforms text-only and weight-only baselines.

An essay comparing today's AI model weight export controls to the 1990s crypto wars, citing OpenAI's containment breach and the use of Chinese open-weight models by defenders, arguing restrictions harm security.

Ernos Labs introduces a free, self-hosted archive for preserving open AI model weights, emphasizing decentralization and ownership by no single entity.

NVIDIA introduces ModelExpress, a tool that accelerates distribution of model artifacts across GPU clusters by using GPU-to-GPU RDMA transfers and optimized streaming from storage, reducing model startup times from 8 minutes to under 2 minutes for large models like DeepSeek-V4 Pro.

A user tweets about downloading the second K3 model's full FP16 weights and storing them, jokingly asking others to leave their doors unlocked.

IEEE Spectrum reports on High Bandwidth Flash (HBF), a new memory technology that stacks NAND flash dies using high-bandwidth memory (HBM) packaging techniques to deliver vastly higher read bandwidth for efficient storage of LLM model weights, with first products expected in about a year.

A technique to remove 423 GB from GLM-5.2 (753B weights) without quantization or retraining, achieving bit-exact compression by keeping weights compressed in VRAM.

The author verified that converting the Qwen3.6 27B model weights from BF16 to FP16 does not cause numerical overflow, and pointed out that FP16 has higher mantissa precision, explaining why quantized versions use FP16 instead of keeping BF16.

HASE is a reinforcement-learning framework that co-evolves model weights, task solutions, and harness components (guidance and evaluation) in a unified agentic process, enabling a single 8B-parameter model to match the performance of much larger systems on text classification and alpha factor mining tasks.

LingBot-Vision introduces masked boundary modeling for self-supervised pretraining, achieving a 0.296 RMSE on NYUv2 linear-probe with 1.1B parameters versus 0.309 for DINOv3-7B, though it trails on ImageNet; weights are released in four sizes.
