The Rundown: French startup Mistral AI just released Mixtral, an open-source 45B parameter AI model using advanced “mixture of experts” architecture to match rivals with far lower cost — while also announcing an eye-popping $415M Series A round that values the company at $2B.

The details:

  • Mixtral matches or outperforms models like LLaMA 2 and GPT-3.5 on most benchmarks while running 6x faster.

  • It significantly improves on past Mistral multilingual and scientific reasoning abilities in areas like math and code generation.

  • Mistral also introduced La Plateforme, which provides API access to hosted versions of Mixtral and its other models to quickly build apps.

Why it matters: With lean team of top researchers and rapid iterations, Mistral continues pushing boundaries on efficient yet powerful open models. Notably, the new $415 Series A round comes about 6 months after a $113m seed round — showing serious money is flooding into open-source.

The Rundown: In the wake of Google’s backlash around the ‘faked’ Gemini demo (covered yesterday), creator Greg.Technology just replicated the video using GPT-4V in real-time —  prompting without edits to highlight how far ahead GPT-4V is when even compared to the staged Gemini demo.

The details:

  • Greg recreated key parts of the polarizing Gemini demo, which wowed viewers before being exposed as a misleading representation of the model’s capabilities.

  • Greg voiced over GPT-4V generating live reactions to his drawings, emoji signals and games, achieving a responsive back-and-forth.

  • He published the code and acknowledged the remake wasn't as polished as Google's production, but demonstrated ChatGPT's prowess in real-time.

The relevance: GPT-4 looks to still set the gold standard, excelling at voice tasks even without edits. Videos like this make the Gemini misstep look even worse — presenting serious questions heading into a critical launch for Google.

Demo drama aside, Google has reportedly floated "Project Ellmann" to leverage Gemini AI and generate users' life events from just data from your phone. Envisioning AI that knows "everything about your life," features could include chatbots detailing your bio and travel history from photos.

Stanford researchers just introduced W.A.L.T., an AI system that generates photorealistic and consistent video from text prompts or still images — while also capable of outputs with consistent 3D camera motion. Check out some of the the wild demo generations here.
