In a test on atomic.chat, locally hosted Kimi K3 (8X B300s) produced the most convincing physics in three browser-based crash scenes, outperforming GPT 5.6. Kimi K3 used 32.7K tokens at $0 cost, while others cost $0.15-$0.45. The test involved generating self-contained HTML simulations; Kimi K3 handled damage persistence best.

NVIDIA becomes OpenAI's loan guarantor? AI bubble may have entered circular financing phase
Published Jul 27, 2026The author analyzes that NVIDIA is guaranteeing a $250 billion loan for OpenAI to lease SoftBank's data center, suggesting the AI bubble has entered a phase where sellers need to prop up demand. They also note that low-cost Chinese AI (e.g., Kimi K3) and open models are challenging the assumption that high-performance AI requires expensive GPUs, potentially leading to overinvestment in data centers.
