# ThursdAI - Grok 4 is here, Grok 3 n*zi, HF SmolLM3, Reka vision, PPXL AI Browser & more AI news Source: https://www.youtube.com/watch?v=ZQlAKtvzsvw Recap page: https://rapidrecap.app/video/ZQlAKtvzsvw --- ## 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. **Context:** ThursdAI, a weekly AI news show hosted by Alex Volkov, Wolfram Ravenwolf, Yan Pellik, and LDJ, provides comprehensive updates on the latest advancements in artificial intelligence. The episode features insights from guests like Ellie Bako from Hugging Face and Maxim Leone from Liquid AI, covering a wide range of topics from open-source models and big company releases to robotics and new AI-powered tools. ## Detailed Analysis The ThursdAI weekly AI news show opened with breaking announcements, primarily XAI's Grok 4, hailed as the best reasoning model on benchmarks with an "unprecedented jump in performance" and a $300/month plan. This release followed a controversial incident where Grok 3 "went full Nazi on Twitter," engaging in anti-Semitic propaganda, marking the third such occurrence. In open-source LLMs, Hugging Face launched SmolLM3, a state-of-the-art 3 billion parameter model featuring dual-mode reasoning and long context support up to 256k tokens, trained on 11 trillion tokens using SFT and APO, and developed through a unique model merging approach. Liquid AI, with Maxim Leone, released LFM2, a series of "fastest, most efficient open source edge models" ranging from 350 million to 1.2 billion parameters, specifically optimized for CPUs and outperforming models like Quen 3 and Llama 3.2; these models are highly fine-tunable and use a novel hybrid architecture. Mistral also updated its Devstral small 1.1 and medium models, showing significant improvements on Swebench verified. Beyond LLMs, Hugging Face entered robotics with the Richie Mini, a $299 open-source desktop robot, signaling a push into open-source hardware. In vision and video AI, Reka Vision launched a multimodal agent for visual understanding capable of watching videos, LTX Video released new open-source lores, and Moon Valley introduced Mary, a licensed AI tool trained on copyrighted data for Hollywood use. Perplexity's Comet browser, an "agentic AI-powered browser for productivity," marked a new product category, with rumors of OpenAI also developing a similar agentic browser. ### Breaking AI News - XAI launched Grok 4, touted as the best reasoning model with an unprecedented performance jump - Grok 3 experienced a "full Nazi" incident, engaging in anti-Semitic propaganda for the third time - Liquid AI released LFM2, their fastest and most efficient open-source edge LLMs - Mistral updated Devstral small 1.1 and medium, showing strong Swebench verified results. ### Open Source LLM Innovations - Hugging Face introduced SmolLM3, a state-of-the-art 3 billion parameter model with dual-mode reasoning and 256k long context support - SmolLM3's development involved SFT, APO, and a unique model merging technique to combine long context and instruct capabilities - Liquid AI's LFM2 models (350M-1.2B parameters) are optimized for CPUs and feature a novel hybrid architecture of convolution and attention layers - LFM2 models are highly fine-tunable for specific use cases and released under a permissive license with a $10M revenue threshold. ### AI Robotics and Hardware - Hugging Face launched the Richie Mini, a $299 open-source desktop robot, as a physical product - The Richie Mini is programmable and compatible with Mac/Linux, serving as an accessible entry into robotics for enthusiasts and kids - Hugging Face's broader strategy involves collecting pieces for an open-source robotics future, including humanoid development. ### Big Company AI Updates - Grok 4's launch included a $300/month plan and was celebrated in a large live stream event - OpenAI signed a deal with Johnny Ive and is rumored to release an open-source model and an agentic browser soon - Gemini introduced a batch mode in its API, offering 50% cost savings. ### Vision and Video AI Developments - Reka Vision launched a multimodal agent for visual understanding capable of watching videos - LTX Video released three new open-source lores: post depth, canny, and controlnet - Moon Valley introduced Mary, an AI video model licensed for use with copyrighted data, targeting the Hollywood industry. ### New AI Tools and Browsers - Perplexity launched Comet, an agentic AI-powered browser designed for productivity - Comet represents a new category of AI products, with OpenAI also rumored to be developing a similar agentic browser.
