🤖 Altman responds to complaints over “rushed” GPT-5 launch

During a Reddit AMA, Sam Altman faced a flood of questions - from bugs in the new model to calls for bringing back GPT-4o.

The main gripe: GPT-5 felt “dumber” than its predecessor. Altman explained that on launch day, a new “router”, the system that chooses between a fast model and a deeper-thinking one, wasn’t working, hurting quality. The fix is now live.

🔸 Will make it clear which model answers each query
🔸 Plus user limits will be doubled
🔸 May bring GPT-4o back for Plus
🔸 Model-selection algorithm will be refined

One viral moment: during the launch, a chart showed a smaller value as a taller bar, instantly memed as a “chart crime.”

Altman called it a “mega-fail.”

He closed the AMA promising to “stabilize everything and keep listening to feedback.”

🧪 The AI "vaccine" against bad behavior

Anthropic has been experimenting with a curious safety trick — giving its AI a small, controlled “dose of evil” during training so it learns to recognize and avoid it later.

🔸 Researchers pick a negative trait (like aggression or manipulativeness)
🔸 They find its neural “signature” by tracking which neurons activate when the model shows it
🔸 They tweak this signature to see how the model’s behavior changes
🔸 During training, they filter out overly “toxic” data — but also inject a bit of the trait under supervision, so the AI learns to detect and block it

The idea is similar to a vaccine: expose the system to the problem in small amounts, so it builds resistance.

In theory, this could help AI spot and shut down its own toxic, manipulative, or overly flattering responses — without waiting for humans to catch them.

🧪 Chai Discovery secures $70M to revolutionize drug development with AI

Biotech startup Chai Discovery has raised $70M in Series A funding to advance its AI-driven drug discovery platform.

The round was led by Menlo Ventures and Anthropic, with backing from Yosemite, DST Global Partners, SV Angel, Avenir, DCVC, and existing investors like Thrive Capital, OpenAI, and Fred Ehrsam.

🔸 Founded in 2024 by veterans from Absci, Facebook AI, OpenAI, and Stripe, with former Pfizer R&D chief Mikael Dolsten on the board.

🔸 Flagship model Chai-2 designs antibodies de novo with up to 20% hit rates — compared to ~0.1% in traditional labs.

🔸 Works from target data alone, creating antibodies that bind precisely to their antigen.

🔸 Could drastically speed up and cut costs of developing treatments, including for rare diseases.

With this funding, Chai aims to expand its platform and deepen partnerships with pharma — pushing toward faster, more precise, and personalized medicine.

🚀 NASA kicks off the race for a “Martian internet”

NASA will no longer build its own Mars data relays - instead, it plans to buy communications “as a service,” just like it does for astronaut transport.

The goal: a full system to move data from the Martian surface, through orbit, and back to Earth.

🔸 Current Mars data comes via aging orbiters like MRO and MAVEN
🔸 New commercial solutions are needed before these satellites fail
🔸 Blue Origin is developing an orbital relay based on Blue Ring (launch planned for 2028)
🔸 Rocket Lab and SpaceX are also in the race - SpaceX wants to adapt Starlink for Mars comms

If successful, this could create the backbone of a true interplanetary internet.
