PrismML compressed a 27B-parameter Qwen model from 54GB to under 4GB using 1-bit and ternary weights, and Apple is evaluating the technology for on-device Siri.

Bonsai 27B compresses Alibaba's Qwen3.6-27B into 1-bit and ternary weights, shrinking a 54GB model to as little as 3.9GB so it runs on an iPhone.

Three new arXiv papers reveal hidden costs in quantized reasoning models, single-token failure triggers, and a new framework that cuts agent memory errors by up to 79%.

Google DeepMind's new QAT checkpoints shrink the Gemma 4 E2B model to under 1GB, making serious on-device AI viable for phones and budget laptops.

Top open-weight models for self-hosting in 2026, with verified VRAM requirements, benchmark data, and tools to deploy them on consumer and server hardware.

The definitive guide to open-weights AI models in 2026 - top picks by size tier, use case, benchmark scores, and deployment hardware. From 400B+ MoE giants to 1B edge models.

How much quality do LLMs lose when quantized from BF16 to INT8, Q6, Q5, Q4, Q3, Q2? Per-model delta tables across MMLU, HumanEval, and perplexity, with VRAM and throughput data for every major quantization format.

A benchmark-driven comparison of the top open-source LLM inference servers - vLLM, SGLang, TGI, llama.cpp, TensorRT-LLM, LMDeploy, and more.

Two researchers fused all 24 layers of Qwen 3.5-0.8B into a single CUDA kernel launch, making a five-year-old RTX 3090 deliver 1.8x the throughput of an M5 Max at equal or better efficiency. The gap was software, not silicon.

Google Research's TurboQuant compresses LLM key-value cache by 6x and delivers 8x speedup on H100 GPUs with zero accuracy loss - no fine-tuning required.
