GPT-5: OpenAI’s Biggest Leap Yet

After months of speculation, GPT-5 has landed, and it’s not just a marginal upgrade. This model blends speed, deep reasoning, and better real-world usefulness into one system that knows when to think fast and when to think harder.
Key upgrades:
Adaptive reasoning: A built-in “router” decides on the fly whether you get a quick answer or GPT-5’s longer “thinking” mode.
Massive coding gains: From complex frontend builds to debugging big repos, GPT-5 can now turn a single prompt into polished websites, apps, and games, with actual design taste.
Sharper writing: Handles structural nuance, subtle tone, and literary depth, from business reports to poetry that doesn’t sound like a fridge magnet.
Best-in-class health partner: Tops HealthBench, proactively flags issues, and adapts to your knowledge level (without trying to play doctor).
On benchmarks, GPT-5 sets new state-of-the-art scores in math, coding, multimodal reasoning, and health. It’s also ~45% less likely to hallucinate than GPT-4o, and six times more accurate than o3 in long-form factual answers.
For the toughest tasks, there’s GPT-5 Pro, a longer-thinking variant that external experts preferred nearly 70% of the time over GPT-5 Thinking.
Rollout: GPT-5 is now the default for all ChatGPT users, with Plus and Pro subscribers getting higher usage caps and access to Pro mode. Enterprise and Edu follow next week.

NASA & Google’s AI Medic for Mars

When you’re months from Earth, you can’t just call Houston for a check-up. Enter Crew Medical Officer Digital Assistant (CMO-DA), a joint NASA-Google experiment in autonomous astronaut healthcare.
Running on Google’s Vertex AI, CMO-DA takes speech, text, and images, then guides astronauts through diagnosing and treating issues in comms-blackout scenarios. Early tests on ankle injuries, ear pain, and flank pain saw up to 88% diagnostic accuracy.
NASA plans to make it more “situationally aware” for space-specific conditions like microgravity, but the same tech could eventually land in terrestrial clinics.

Pinterest Pumps the Brakes on Agentic Shopping
CEO Bill Ready says fully autonomous AI shopping agents are still “a very, very long cycle” away—but Pinterest is already leaning into AI-driven personalization and search. Revenue beat expectations at $998M, but EPS missed, and shares dipped.
Meta Buys Voice AI Startup WaveForms
Hot on the heels of acquiring PlayAI, Meta snapped up WaveForms, an eight-month-old startup chasing the “Speech Turing Test” and “Emotional General Intelligence.” Expect deeper voice tech integration in Meta’s Superintelligence Labs.
Nvidia & HPE Build Germany’s Next AI Supercomputer
The Blue Lion supercomputer system will run on Nvidia’s upcoming “Vera Rubin” chips, going live in 2027. Nvidia also unveiled its “Climate in a Bottle” AI model, which can forecast decades-long climate scenarios at kilometer-level resolution.
