DELIVERED

When you buy an Office license, you're paying for features or capabilities. With AI, features and capabilities are nearly unlimited, and THE VALUE OF SOFTWARE BECOMES WHAT IT ACTUALLY DOES. That's why OpenAI and Anthropic charge by tokens used rather than seats.

META'S VISION FOR PERSONAL SUPERINTELLIGENCE

Meta is betting on personal superintelligence as the future of computing: AI that knows you deeply, lives on devices like smart glasses, and helps you pursue your goals, relationships, and creativity. Unlike centralized visions of automation and universal basic output, Meta argues that progress comes from individual agency and empowerment. The company plans to invest heavily in infrastructure and safety to bring this technology to billions.

AMAZON INVESTS IN ‘NETFLIX OF AI' START-UP FABLE, WHICH LAUNCHES SHOWRUNNER: A TOOL FOR USER-DIRECTED TV SHOWS

Amazon has invested in Fable, a startup with an AI-generated TV show service called Showrunner. The money from the investment will help develop Showrunner, which allows users to create scenes (or entire episodes) of a TV show using prompts. Showrunner will be free at launch, but the company eventually plans to charge $10-$20 per month for credits. Fable's AI models have guardrails that block offensive, illegal, or copyrighted material.

QUERY FAN-OUT TECHNIQUE IN AI MODE: NEW DETAILS FROM GOOGLE

Google's query fan-out technique, available in AI Mode, Deep Search, and some AI Overview experiences, makes multiple background searches based on an initial question. It uses a large language model to interpret queries and 'fan out' to multiple related searches, including on topics the user never explicitly mentioned. The responses are then combined into a single response with links.

30% OF "HUMANITY'S LAST EXAM" ANSWERS ARE LIKELY WRONG

FutureHouse researchers found that nearly a third of biology and chemistry questions in the prominent PhD-level AI benchmark contain answers directly contradicted by peer-reviewed literature. The errors stem from HLE's unusual design that created "gotcha" puzzles that even confused human experts.

PRICING AI PROOFS-OF-CONCEPT: FREE PILOTS WILL KILL YOU

AI agents deliver real business value, so they should be priced accordingly from day one. Companies that position their products as pilots or technical proof-of-concepts are competing on features instead of outcomes. They should charge enough to filter out the curious and co-create the ROI model that closes the deal. Customers who see how agents help save time, reduce errors, and increase throughput won't be able to argue with the business value.

AGENT INTERACTION GUIDELINES (AIG)

Agents are reshaping roles and workflows, changing how software is planned, built, reviewed, and deployed. Developer's roles have shifted to orchestrating input and reviewing output. The Agent Interaction Guidelines are a set of foundational, evolving principles and practices for designing agent interactions that integrate naturally into human workflows. They are still being written, and more is expected to be added as the community gains more experience.

GEPA: REFLECTIVE PROMPT EVOLUTION CAN OUTPERFORM REINFORCEMENT LEARNING

Traditional RL approaches need thousands of expensive trial-and-error runs to learn from simple success/failure scores. GEPA uses natural language reflection to diagnose what went wrong and evolve better prompts through a Pareto-based selection strategy. GEPA (Genetic-Pareto) dramatically outperforms both reinforcement learning methods like GRPO and leading prompt optimizer MIPROv2 while requiring up to 35× fewer training attempts.

SOMETHING THAT HAS BECOME UNDENIABLE THIS MONTH

The best available open weight models new come from Chinese AI labs. The delay in the release of OpenAI's open weights model may be due to a desire to be notably better than the truly impressive lineup of Chinese models. This post lists the biggest Chinese model releases of this month, along with links to notes on each one.

‘VIRTUAL SCIENTISTS' TO SOLVE COMPLEX BIOLOGICAL PROBLEMS

Stanford Medicine developed a team of AI agents that mimic real research labs, complete with a virtual PI, specialized scientists, and a built-in critic. The system has already designed promising COVID-19 nanobodies in days that outperformed existing antibodies in lab tests.
