1/ Sam Altman Shuts Down Musk’s OpenAI Takeover Attempt—For Now

Elon Musk just threw a $97.4B bid at OpenAI’s nonprofit arm, hoping to take control and bring back its open-source roots. Sam Altman shut it down fast, joking he’d buy Twitter for $9.74B instead. Musk’s backed by xAI and big investors, but OpenAI’s already eyeing a $40B SoftBank deal at a $260B valuation. The feud between these two just keeps escalating, and this definitely won’t be the last move in their AI power struggle.

2/ GPT-4.5 Lands Soon, But GPT-5 Is the Real Showstopper

OpenAI just scrapped its o3 model and is going all-in on GPT-5, bundling everything into one streamlined system. Before that, GPT-4.5 ("Orion") drops in a few weeks as the last non-chain-of-thought model. Free users get standard GPT-5, while paid tiers unlock more power. Altman says 4.5 is coming in weeks, GPT-5 in months. This move simplifies things—no more model confusion, just one AI that picks the best tools for the job.

3/ Is Mistral’s ‘le Chat’ the Sleeper Hit of the AI Assistant Race?

Mistral just dropped new mobile apps for its ‘le Chat’ AI assistant, plus a big upgrade with faster responses and enterprise options. It’s got web search, docs, coding, and image gen, plus a ‘Flash Answers’ feature that’s 10x faster than ChatGPT. Pricing starts free, with Pro at 15/monthandTeamat15/monthandTeamat25/user/month. Enterprises get custom deployment, like on-premise setups. Mistral’s not the top dog, but its speed and flexibility could win over more users. Cool moves!

4/ AI-Generated Video Without the Lawsuits? Adobe Says Yes

Adobe just dropped its Firefly Video Model in public beta, calling it the first “commercially safe” AI video tool. It generates 1080p clips from text or images, with solid camera and motion control. Firefly won’t train on user data and starts at $9.99/month for 20 videos. New features include AI lip sync, translation, and 3D scene references. With legal safety as its selling point, Firefly could be the go-to AI video tool for brands.

5/ DeepMind’s New AI Solves 84% of Insane Geometry Problems—Can You?

Google DeepMind just launched AlphaGeometry2, a new AI that aced 84% of International Math Olympiad geometry problems—outperforming the average gold medalist. It combines a Gemini model with a symbolic engine to handle complex proofs, solving 42 out of 50 problems. Trained on 300M+ synthetic theorems, it’s a huge leap from its predecessor. This breakthrough could seriously boost progress in math-heavy fields like physics. Pretty impressive!
