AI solves a 50-year-old math problem. Atlas wins CES. Musk lawsuit proceeds.

AI Solves 50-Year-Old Math Problem

Terence Tao confirms GPT-5.2 "more or less autonomously" solved Erdős Problem #728, a 50-year-old open problem in mathematics. The problem's original formulation was flawed and only properly reconstructed recently.

Tao notes this is "genuine increase in capability" and finds the AI's ability to "rapidly write and rewrite expositions" even more significant than the solution itself.

LTX-2 gets GGUF quantization, ComfyUI adds NVFP4 support, and turbo LoRAs speed up generation.

LTX-2 GGUF Quantized Models Available Kijai releases LTX-2 GGUF quantized models. Q6 quality reportedly better than FP8. Allows running LTX-2 video model on consumer GPUs with less VRAM. Requires specific ComfyUI-GGUF PR for compatibility.
ComfyUI Gets NVIDIA NVFP4 Support Official ComfyUI blog post on new NVIDIA GPU optimizations: NVFP4 quantization, async offload, and pinned memory. 3-4x throughput vs FP16/BF16 for linear layers. Models compressed up to 70% without losing quality.
Z-Image IMG2IMG Ultimate Photorealism Workflow Definitive Z-Image IMG2IMG workflow for character LoRAs achieving ultimate photorealism. Includes workflow, model links, LoRA, and exact training method.
Qwen-Image 20x Faster Turbo LoRA Wuli Art releases V3.0 of Qwen-Image-2512-Turbo-LoRA. 4 or 8-step turbo LoRA that's 20x faster than original while matching quality.
