Barely two weeks into the AI industry’s new “pacing” era, the frontier’s two biggest rivals are still launching on each other’s heels.Anthropic and OpenAI shipped models just 90 minutes apart, with a powerful new Opus 5.5 topping leaderboards and GPT-6 Sol and Luna cutting prices in half for near-frontier intelligence. The pace? Still feels pretty fast! In today’s AI rundown:

• Anthropic, OpenAI deliver dueling frontier AI discounts
• OpenAI taps mathematicians to check its AI
• Build, test, and publish an app without leaving Codex
• a16z’s new AI-driven college alternative

LATEST DEVELOPMENTSANTHROPIC & OPENAI Anthropic, OpenAI deliver dueling frontier AI discountsImage source: Anthropic / OpenAIThe Rundown: Anthropic just released Claude Opus 5.5, a model that surpasses its predecessor and even the top-tier Fable 5.1 at 40% less price, with OpenAI answering with GPT-6 Sol and Luna, two new models at half the price of the versions they replace. The details:

• Opus 5.5 takes the top overall spot on AA’s Intelligence Index at 58, blowing past previous leaders Fable 5.1 and GPT-6 Astra at 53.
• Anthropic addressed Claude’s much-criticized “Claudish” writing, saying that 5.5 skips jargon and sticks more closely to users’ own style rules.
• Anthropic also said 5.5 scored “the best score to date” on internal alignment benchmarking, noting it as the first release following Anthropic’s “pacing” calls.
• GPT-6 Sol and Luna come in with slight score increases over their 5.6 counterparts, but are 50% cheaper at $0.10/$0.50 per M (Luna) and $2/$10 (Sol).

Why it matters: Anthropic wins the day if we’re comparing releases head-to-head, with Opus showing some serious leaps at a reduced cost. OAI’s rollout is largely cost-driven, but a 50% cut for still powerful models isn’t something to dismiss. Sam Altman said pacing “does not mean stopping,” and that seems to be true for both AI leaders so far. TOGETHER WITH COREWEAVE Fully Connected 2026: F1, BattleBots, and PitbullThe Rundown: What do Pitbull, BattleBots, and AI agents all have in common? They’re all happening at Fully Connected 2026.

• OpenAI says its internal model has resolved problems across most branches of mathematics, alongside its claimed Navier–Stokes breakthrough.
• A new advisory group, hosted at Princeton’s Institute for Advanced Study, includes mathematicians Timothy Gowers, Martin Hairer, and Melanie Matchett Wood.
• It will advise on vetting and releasing results and can weigh in on its views, but members aren’t paid by OAI and won’t advise on how fast it pushes math work.
• Earlier this month, 27 Fields Medalists, including Hairer, signed a letter accusing AI labs of rushing out results without proper credit or understanding.

Why it matters: That’s 100+ results in under four weeks, each needing human review for correctness, originality, and credit — the pile-up the Fields Medalists warned about. The advisory group can shape how those results are vetted and released but has no say over how fast the model produces them.AI TRAINING Build, test, and publish an app without leaving CodexThe Rundown: In this guide, you will learn how to use Codex to prep your app for the App Store. You just need an app, Xcode installed on your Mac, and an Apple Developer account. Codex can handle the rest.Step-by-step:

• If you don’t have a ready-to-publish app, Codex can create one. Try: “Build me a calendar planning iOS app for couples. No database or payments”
• Make sure you have Xcode installed, along with at least one iOS simulator. Ask Codex for help if you’re not sure how to do this
• Tell Codex to test the app in the simulator. When it opens, prompt: “Scan for App Store readiness, list what’s missing, then fix it and package it for Xcode”
• Sign up for the Apple Developer Program and subscribe at $99/year. Then, push the final Xcode project to the App Store via App Store Connect

Pro tip: Have Codex create the required privacy policy and support pages in Notion.

Stack workshops, code talks, and builders’ sessions back to back, or leave room to go deep on one track.While onsite, you can:

• Map a personalized agenda around the services you’re actually shipping with
• Swap between structured sessions and open sandbox time as the week unfolds
• Pressure-test your build against edge cases with the engineers who built the service

• Udemy’s Gagan Biyani leads the Academy, promising courses from instructors “your textbooks are written about” like Sam Altman and Brian Armstrong.
• The founding class will be roughly 50 students in Fall 2027, with admissions based on what students have built or shipped over grades or test scores.
• Students will also receive $50K in compute credits, a $5K travel budget, and time inside partner startups, with no homework or tests in the program.
• A two-year version planned for 2028 would charge elite-college tuition if regulators approve it, though for now students leave without any degree.

Why it matters: The educational system is facing an upheaval from AI, but there have been few options (Alpha School being one of the few) to challenge the pre-AI classroom model. a16z’s Academy arrives with a learning overhaul and tie-ins to major labs and tech leaders, making it a potentially elite pipeline for the AI builders of the future. QUICK HITSCOMMUNITY AI WORKFLOW OF THE DAY▸ Adriana used ChatGPT to build a local grain supply chainToday’s workflow comes from reader Adriana Pausenwein:“I built an AI-assisted vertical grain supply-chain resilience workflow after discovering that the rye flour we normally use for homemade bread had been discontinued.I started by asking ChatGPT to locate alternative retail and bulk suppliers for rye and spelt flour. We compared package sizes and prices, contacted local mills and bulk-food suppliers, and expanded the search from finished flour to locally available whole grain.The workflow then moved offline. ChatGPT helped us identify the resources we already had: agricultural land, grain bins, a cultivator, a seeder, an old but functional industrial grain crusher, and even a combine. We also realized that a friend owns a seed-cleaning plant and that our farming neighbors can connect us with local rye and spelt growers.Our next steps are to test whether a household coffee grinder can produce sufficiently fine flour from grain, source fresh food-grade rye and spelt locally, and investigate growing a small crop ourselves.AI was most useful not because it gave us one answer, but because the conversation kept changing the question. We began with, ‘Where can I buy rye flour?’ and ended with, ‘Why are we buying rye flour when we have most of the infra to produce it ourselves?’”See Adriana’s workflow here. How do you use AI?
