Please welcome GPT-6 Sol and GPT-6 Luna to the GPT-6 universe. GPT-6 Sol and Luna build on the advances behind GPT-6 Astra, bringing much of its strengths into faster and more affordable models to support work at scale. We’ve also made caching and inference more efficient, and we’re passing the savings directly to you: 50% lower API prices for Sol and Luna compared with GPT‑5.6 promotional pricing.

GPT-6 Astra is here. We hope it will begin to enable a new generation of entrepreneurship, scientific discovery, and building. We believe it is the best model in the world for computer use, professional work, science, coding, cybersecurity, and more. It took us some extra time to ensure that we could meet the safety and alignment standards required for this capability level, but we think you’ll find it worth the wait. It scores 98% on FrontierMath Tier 4, 99.9% on ARC-AGI 3, and 100% on ExploitBench.

Everyone is waking up to the fact that code-review is the bottleneck of 2026 I'm bullish on ramping review agents - but the vibes coming from - 0github.com - asi.review - pierre.co start to hit closer to home on where we need to go

Trying to visualize that Server-Side Rendering (SSR) isn't just about SEO, it actually makes the site faster. And why PPR is the goat. Main cost = 🟥 JS load & Hydration 🟡⇆🔵 Region Latency
A diagram comparing four web content rendering methods: Client-Side Rendering (CSR), Dependent Data CSR, Server-Side Rendering (SSR), and Streaming SSR, showing the data flow between the server, APIs, and the client during webpage generation.

A visualization of three web content delivery strategies: CSR with Cached HTML, where the client fetches data from two APIs; CSR with Cached HTML and GraphQL, where the client fetches data from a single GraphQL API; and Partial Pre-Rendering with Streaming SSR, where pre-rendered HTML is streamed to the client and additional data is fetched from two APIs. Each strategy includes an 'Edge' server that serves cached HTML shell to the client.

I love node.js so much, overnight it multiplied my earning power, made me full stack where it counts, introduced to me to life long friends and collaborators, literally took me across the world many many times, and now I’m building a company on top of it. Unbelievable software.

The View Transitions API now supports MPAs (Multi-page applications) and it's truly mind-blowing. This is a server-side rendered @astrodotbuild website where every interaction is a full-page load. There is _zero_ JavaScript on this site ✨

We added priority hints <img fetchpriority="high"> to the main image of the @eBay item page and immediately saw an LCP improvement of ~150ms (Chrome). This is easily one of the most effortless speed wins for us. Truly a 1-line change @ebaytech. #velocity
