“Elon Musk’s xAI acquired X The deal creates a joint entity with a $113B valuation, combining both xAI and X’s data, models, compute, distribution and talent Will be interesting to see how xAI’s Grok evolves post this move! https://x.com/adcock_brett/status/1908913463407034527
“We’ve run independent evaluations of Grok-3 and Grok-3 mini on our suite of benchmarks! Grok-3 currently doesn’t do extended reasoning, while Grok-3 mini is a reasoning model. We ran Grok-3 mini with both “low” and “high” reasoning effort. Full results in thread! https://x.com/EpochAIResearch/status/1910685268157276631
“Grok-3-mini comes with two modes: low reasoning effort and high reasoning effort https://x.com/scaling01/status/1910102070125854755
“Grok-3 API just went live!!! grok-3: Input: $3.00/M – ($5.00/M) Output: $15.00/M – ($25.00/M) normal mode- (faster inference mode) grok-3-mini: Input: $0.30/M – ($0.60/M) Output: $0.50/M – ($4.00/M) https://x.com/scaling01/status/1910101532269302003?s=46

“Optimus job opening for Technical Animator was posted last week: “Optimus simulation team is responsible for building core components to visualize all aspects of Optimus… for understanding, testing bot functionality, and generating synthetic data for training deep NNs.” https://x.com/TheHumanoidHub/status/1909312550564774249
“Tesla made Optimus walk better with reinforcement learning in simulation and is now working to apply the same technique to manipulation tasks. https://x.com/TheHumanoidHub/status/1909312554838769813
“Tesla engineers talked about the in-house Autopilot simulation pipeline built on top of Unreal Engine on AI Day 2022, and also showed early work in simulating Optimus using the Autopilot simulator. https://x.com/TheHumanoidHub/status/1909312552636760391
“another thing i disagree with lots of AI people about: training large models is not inherently scientifically valuable! e.g. training that huge grok model killed lots of trees, and taught us nothing so many discoveries could’ve been made on 100M param language models -” / X https://x.com/jxmnop/status/1908994251909738682

“Scaling reasoning capabilities in LLMs using complex Reinforcement Learning (RL) methods lacks open, simple implementations. Open-Reasoner-Zero presents an accessible, open-source RL approach. It shows a minimalist setup using standard Proximal Policy Optimization (PPO) with https://x.com/rohanpaul_ai/status/1908776692140958153
““Your Tesla has better AI than any military aircraft.” — Palmer Luckey, CEO of Andruil, who earned a standing ovation at TED today. “Countries only go to war when they disagree who the victor will be.” “We have to prove we have the capacity to win.” “Manufacturing capacity is https://x.com/FutureJurvetson/status/1909726001770512473
