Latent Space · rss · 2026-08-13

This Latent Space AI newsletter covers major frontier model releases and ecosystem updates:

xAI Grok 4.6: A 1.5T parameter model focusing on long-running agents and visual tasks. It achieves frontier-level price/performance with excellent Terminal-Bench results at a fraction of competitor costs. Elon noted Grok 4.7 training has begun.
Open-Weight & Frontier Clashes: Alibaba open-sourced Qwen3.8-Max (2.4T MoE) focusing on long-context but lacking vision initially; DeepSeek V4 Pro GA enters the market at extremely low prices ($0.435/M input); Microsoft released its first from-scratch reasoning model, MAI-Thinking-1.
Multimodal & Edge: LTX-2.5 open video stack upgraded with joint audio generation; Cohere released North Micro Vision (lightweight VLM); Google DeepMind introduced SL2T for sign-language-to-text.
Inference & Compression: vLLM added support for Azure Blob and giant models; LLM Compressor introduced MoE expert pruning and arbitrary precision quantization, further lowering deployment barriers.
