OPENAI LAUNCHES GPT-5.6 SOL, TERRA, AND LUNA ON APPS AND API

OpenAI has released its new frontier model family for ChatGPT Work, Codex, and the OpenAI API. The GPT-5.6 family has three tiers: Sol, the flagship model; Terra, a lower-cost everyday work option; and Luna, the fastest and most affordable model. The series features higher intelligence per token, lower estimated cost for complex work, and stronger agentic performance. There is a new 'ultra' setting that coordinates multiple agents across parallel workstreams for demanding tasks.

THE PULSE: INTERESTING AI CODING STATS FROM CURSOR

A recent report from Cursor shows large disparities in coding productivity among its users, with top 1% power users generating up to 40,000 lines of code per week, compared to the median user's 700 lines. The study also shows that input tokens make up about 90% of AI token usage during coding, suggesting that developers spend more time reading and understanding existing code than writing new code.

LOVABLE IS REPORTEDLY IN TALKS TO RAISE $300M AT A $13.2BN VALUATION

Lovable is reportedly in talks to raise $300m at a $13.2bn valuation, roughly double its $6.6bn December Series B, according to Sifted. The Swedish vibe-coding startup has surpassed $500m in annualized revenue with just 146 staff, though the round remains unconfirmed and Lovable declined to comment. The surge reflects both Europe's push to prove it can produce AI giants and broader concerns about a possible AI-funding bubble.

ZUCKERBERG PLEDGES ‘AGGRESSIVE' PRICING WITH META'S FIRST PAY-TO-USE AI

Meta's Muse Spark 1.1 includes a new paid tier for developers. Developers are able to use Meta's model for free up to a point, then they'll be required to pay for access. Meta's API pricing is roughly 25% of the cost of other top competing models. Mark Zuckerberg has described Muse Spark as having state-of-the-art - or very close to it - agentic reasoning and tool use.

HUMANOID ROBOTS CONTROLLED BY SURGEONS DID WORLD-FIRST OPERATION ON LIVE PIGS

Humanoid robots controlled by skilled human surgeons recently removed the gallbladders from living pigs in an unprecedented medical experiment. The approach takes a fraction of the space needed in an operating room and is easy to deploy. The experiment used a Unitree G1 humanoid robot, which has a starting price of $13,500. Unitree's humanoid robots teleoperated by surgeons are still very much in the experimental phase, but the approach could eventually be used in smaller hospitals and clinics that lack the resources to install expensive surgical robots.

APPLE EXPLORING WAYS TO RUN MUCH LARGER AI MODELS DIRECTLY ON IPHONES

Apple has reportedly held meetings with PrismML about how it could use the startup's technology to run much larger AI models directly on iPhones. PrismML has managed to shrink down Alibaba's Qwen 3.6 model, which has 27 billion parameters, to run entirely on an iPhone Pro. Larger models running directly on iPhones would allow for more Apple Intelligence features to run on-device, which could reduce Apple's costs and further enhance user privacy.

HOW GITHUB GAVE EVERY REPOSITORY A DURABLE OWNER

GitHub had over 14,000 repositories across its primary internal GitHub organization. Less than half had clear ownership. This post discusses how GitHub gave every active repository a validated owner in under 45 days, archived the rest, and made ownership the foundation for everything that followed.
