AI doctors, Siri shakeup & more (July 1, 2025)

Good morning!

From AI doctors to AI crackdowns, today’s headlines show just how fast the tech is accelerating, and colliding, with politics and platforms.

Let’s get into it👇

🧠 AI Power Plays

🏥 Microsoft’s AI Doctor Crushes Human Accuracy

Microsoft unveiled its new diagnostic AI, the MAI Diagnostic Orchestrator, which outperformed human doctors by over 4x on tough medical cases. Simulating an expert medical team, the AI achieved 85.5% accuracy, far ahead of physicians’ 20% average. CEO Mustafa Suleyman called it a “step towards medical superintelligence.” It even slashed costs per case.

🍏 Apple Might Dump Siri’s Brain

Apple is reportedly weighing whether to replace its in-house LLM powering Siri with Claude from Anthropic or OpenAI’s ChatGPT. This comes as Apple doubles down on AI with iOS 19, and suggests even the world’s biggest company might not be happy with its homegrown AI. Apple playing the LLM field? That’s new.

🧱 Cloudflare Blocks AI by Default

Cloudflare, which powers traffic for over 20% of the internet, is now blocking AI crawlers by default. Tools like GPTBot and ClaudeBot won’t get access unless a site explicitly opts in. This shifts the burden back to AI makers to prove their data access is legit, and gives publishers more control over who gets to train on their content.

⚖️ Regulation, Politics, and Protection

🧾 Trump’s Megabill Cuts AI Protections

Trump’s sweeping new economic bill has quietly dropped several AI oversight provisions. Senate gridlock and lobbying from the AI sector gutted key safety clauses. If passed, it could be a major rollback of proposed AI protections, just as use cases like autonomous weapons and surveillance heat up.

🧬 AI Designs Functional Antibodies

Chai Discovery, backed by OpenAI, revealed Chai-2, an AI tool capable of designing fully functional antibodies with a 100x improvement over standard methods. The model nailed targets in drug development at a near 20% success rate (normally <0.1%) and delivered them in just two weeks. This could slash time and cost for rare disease research.

🇨🇳 Baidu Open-Sources ERNIE 4.5

Baidu is going open-source with 10 versions of its ERNIE 4.5 model family, including a 424B parameter beast that outperforms DeepSeek V3 despite being half the size. With Apache 2.0 licensing and strong multimodal performance, Baidu’s entering the Western open-source race, and bringing China’s AI rivalry to a global stage.

🧾 TLDR

Microsoft’s AI diagnoses 4x better than doctors. Apple’s thinking about ditching its own Siri model for Claude or ChatGPT. Cloudflare is blocking AI bots by default, and Trump’s megabill is dropping key AI protections. Meanwhile, Chai’s AI designs antibodies at lightning speed, and Baidu's open-source play puts China firmly in the AI race.
