OpenAI launched Codex, a new coding agent that builds features and fixes bugs autonomously It can work on many tasks in parallel, navigate codebases, implement changes, and propose pull requests for review Available for Pro, Enterprise, and Team users

Significant progress in AI and Robotics this week. So, I summarized everything from OpenAI, Google, Tesla, Salesforce, Alibaba, Notion, Foundation Robotics, CMU Robotics, and more. Here's everything you need to know and how to make sense out of it:

Google dropped AlphaEvolve, an AI that discovers algorithms for scientific and computational challenges —Uses Gemini models with auto-evaluation & iteration —Found the first improvement on 1969's Strassen's algorithm —Also boosting efficiency for Google

Google also announced plans to expand Gemini to more platforms, including smartwatches, cars, and XR headsets. Plus, it debuted 'AI Futures Fund' to give startups early access to advanced models, funding, and technical expertise to boost development

OpenAI also dropped multiple product updates, including: —GPT-4.1 and GPT 4.1-mini coding for ChatGPT free and paid users —PDF exports for reports generated via ChatGPT Deep Research —A new Safety Evaluations Hub showing models' safety levels

The Tesla team behind Optimus shared a clip of the humanoid, showing its dance moves, using sim-to-real reinforcement learning Elon shared that Optimus is operational in the Tesla office, moving around unsupervised

Salesforce released xGen-Small family of small AI models It includes two variants, 4B & 9B params, with the larger one proving competitive on long-context understanding up to 128K tokens Both also deliver strong performance on math + coding benchmarks

Alibaba's Qwen team made Deep Research for Qwen Chat available for all users It's pretty much like ChatGPT's Deep Research, providing users the ability to prepare detailed reports on different subjects in a matter of minutes.

Alibaba's Wan dropped Wan2.1-VACE, a unified AI for video creation and editing Available in 1.3B, 14B sizes, the model can handle reference-to-video generation, video-to-video editing, and masked video-to-video editing Open-sourced under Apache 2.0

Notion launched an "AI for Work" suite for its business plan subscribers, offering: —AI meeting notes —Access to different AI models, including GPT-4.1 —Enterprise Search to find answers across different platforms —A research ode to draft docs

California-based Foundation Robotics shipped its production humanoid to its first customer The company says it will be working over coming months to ensure the deployed fleet manages to "perform full shifts"

Researchers at CMU Robotics presented DexWild, a data collection system to gather human hand data across environments In tests, it enabled AI policies to generalize in unseen scenes 3.8x better when compared to training with robot data only

Tsinghua University researchers detailed HuB, a unified framework to help humanoids handle extreme balancing tasks It integrates reference motion refinement, balance-aware policy learning, and robustness training to improve sim-to-real consistency

Stability AI open-sourced Stable Audio Open Small, a text-to-audio AI —341M-parameters —Generates 11s of audio, including drum loops, foley, riffs, and textures —Optimized for Arm-based consumer devices
