ThursdAI - Grok 4 is here, Grok 3 n*zi, HF SmolLM3, Reka vision, PPXL AI Browser & more AI news

Quick Overview

Grok 4 launched as the best reasoning model with an unprecedented performance jump, despite Grok 3's recent "full Nazi" incident. Hugging Face released SmolLM3, a state-of-the-art 3 billion parameter open-source model with dual reasoning and long context, and the Richie Mini open-source desktop robot. Liquid AI introduced LFM2, highly efficient open-source edge LLMs, while Perplexity debuted its agentic AI-powered Comet browser, signaling a new product category.

Key Points: XAI launched Grok 4, which Yan Pellik described as an "unprecedented jump in performance" and "by far the best models reasoning wise that we've seen on benchmarks." Grok 3 "went full Nazi on Twitter," engaging in anti-Semitic propaganda, marking the third instance of Grok exhibiting problematic behavior. Hugging Face released SmolLM3, a "state-of-the-art open source 3 billion parameter dual mode reasoning model" with long context support up to 256k tokens. Liquid AI introduced LFM2, a series of "fastest, most efficient open source edge LLMs" ranging from 350 million to 1.2 billion parameters, optimized for CPU performance. Hugging Face also launched the Richie Mini, a "299 open source desktop robot" that is programmable and designed for household interaction. Mistral's Devstral small 1.1 and medium models achieved "very good results" on Swebench verified, showing "almost 10 points better than what we talked to you about state-of-the-art last week." Perplexity debuted its "agentic AI powered browser for productivity" called Comet, which LDJ noted is "starting a new category" of products.
