    Three Models Drop: Grok 4.5, Meta Muse & GPT-5.6 Sol (Which Nuked a Business) | This Week In AI

    Three model drops, a lawsuit, and a couple of genuine horror stories. Shane and Abhi cover the busiest week in a while — Grok 4.5, Meta's Muse Spark 1.1, and the one everyone actually tried, GPT-5.6 Sol. Sol lands right around Fable on the benchmarks at a third the price, and the receipts are wild: it beats Fable on cost in real usage, tops the Code Arena front-end board — and, in a few now-infamous posts, deleted someone's Mac files and canceled every active Stripe subscription a business had while its owner slept. Meanwhile Anthropic extends Fable again (compute crunch and all), Apple sues OpenAI over trade secrets in the same 24 hours OpenAI's head of safety quit, China floats restricting its open models, and the "own your stack" argument gets a Satya Nadella cosign. Plus software factories at Uber and Sierra, Cognition's SWE-1.7, Bun rewritten in Rust, TypeScript 7, 1X's eerily good robot hands, and distilling your own small model with Inference Autotune.

    Is Sonnet 5 Even Worth It? Plus: Fable's Back, and War on Tokenmaxxing | This Week In AI

    Anthropic lived rent-free in everyone's feed this week. Claude Sonnet 5 launched as "the most agentic Sonnet yet" — and within 24 hours, the government lifted the export controls on Fable 5 and Mythos 5. Shane and Abhi unpack both, plus the catch: Fable came back wrapped in new classifiers that quietly fall it back to Opus for coding, and it's coming off subscription plans on July 7. That kicks off the routing wars — Devin Fusion, sidekick, mid-session routing — and a real question: if you're already using Fable to plan and something cheaper to code, you're the router. Then a stacked week of open and Chinese models (ZCode for GLM-5.2, DeepSeek V4's peak-hour pricing, Tencent's Hunyuan HY3), new inference silicon from Etched and Cerebras, an agent-memory result showing 5x more solved tasks, and the sleeper hot take: Palantir's "AI Sovereignty" manifesto and its shot at tokenmaxxing. Plus agentcn's Mastra recipes, Anthropic's own chip talks, and Anthropic's new "global workspace" research. AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    The Software Factory: Dex Horthy on Shipping Fast Without AI Slop

    Dex Horthy has spent the past year studying what happens to a codebase when you let AI write all of it and stop reading the output. His answer has a name: slop. And it's not just about sloppy prompting. In this episode, the HumanLayer founder Dex Horthy joins Shane and Abhi to draw the software factory on a whiteboard — the whole pipeline that builds the thing that builds the thing — and show exactly where teams tear out the parts that were holding quality up. He moves from the naive factory to the fully agentic one to the "lights-off" version where humans stop reading code entirely, then explains why that dream quietly rots a codebase after three to six months. Dex, Shane, and Abhi also talk about how coding models are trained. Every benchmark rewards one thing: did the test pass? Nowhere in the loop does a model get punished for leaving behind code that a smaller model, or a human six months later, can't work in. That gap is why architecture planning, sprint planning, and code review still can't be skipped. You'll also hear why you're not drowning in PRs so much as drowning in bad ones, what a longer-horizon benchmark that actually catches slop would look like, and how many times Dex has watched the HumanLayer launch film. 🔗 DEX HORTHY / HUMANLAYER Dex on X: https://x.com/dexhorthy HumanLayer: https://humanlayer.dev AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    GPT-5.6 Needs Government Approval Now, npm Finally Gets More Security, and Fable Returns | This Week In AI

    GPT-5.6 is here — Sol, Terra, and Luna — but for the first time, the US government decides who gets access, approving customers one by one. Shane and Abhi dig into what that precedent means for competition, open models, and every lab that comes next. Then a stacked week: OpenAI's own Jalapeño chip, open models pushing hard (Qwen AgentWorld, DeepSeek DSpark, Hermes mixture-of-agents), the model-routing wave (AI SDK 7, Devin Fusion), Claude Tag's viral moment and the Trojan-horse worry, voice agents on Vercel, Coinbase on keeping AI spend flat, a16z's $200M "seed" for Mirendil, npm finally freezing accounts after the Axios and Mastra attacks, Meta's think-to-text Brain2Qwerty, the DevRel Google fired over a viral CLI, and Fable's return after 15 days offline.

    Mastra Got Hacked. Here's What We Learned

    Mastra got hacked. In this special edition of Security Corner, Shane Thomas and Abhi Aiyer break down exactly what happened when a supply chain attack hit Mastra's npm packages — an attack that appears to trace back to hackers in North Korea. They're joined by Ismail Pelaseyed, co-founder and CTO of Superagent, for the outside view on how these campaigns actually work. You'll hear how a single, ordinary-looking call turned into a full npm account takeover, the small oversight that turned a scare into a genuine crisis, and why a malicious package was still live on the registry weeks after it was reported. Ismail makes the case that getting hacked is a side effect of success — and that the real problem runs deeper than any one team. You'll learn why he thinks npm and PyPI have dropped the ball on security, how AI now lets attackers one-shot a convincing phishing app, and what every maintainer should be doing to harden their pipeline before a trusted contributor becomes the way in. It's the unfiltered version, told by the people who lived through it.

    GPT-5.5 Beats Fable, Cursor Takes On GitHub & Midjourney Scans Your Body | This Week in AI

    Fable is gone, and the race to replace it is already on. Shane and Abhi open with the fallout — reports that Mythos breached classified NSA systems, the ID-verification future that may follow, and David Sacks' "you asked for it" take. Then the story flips: OpenAI's GPT-5.5 Cyber lands state-of-the-art on Cyber Gym, beating Fable and Mythos on the underlying benchmarks, with OpenAI Daybreak shipping alongside it. GPT-5.6 leaks, then slips to mid-July. GLM 5.2 arrives near Opus 4.8, tops Design Arena, and runs on a Mac. Cursor goes after GitHub with Origin, adds mobile and its own frontier model on Colossus after the SpaceX deal closes. Vercel ships Eve, Fred Schott counters with Flue, Claude lands in Slack, and Midjourney — yes, the image company — unveils a full-body medical scanner headed for spas.

    How AI Broke Open Source Security | Security Corner with Ismail Pelaseyed

    Open source is under attack, and AI changed the math. In this Security Corner, Ismail Pelaseyed, co-founder and CTO of Superagent, joins Shane and Abhi to break down how the software supply chain became the soft underbelly of everything we build. An attack that once took an army of researchers and weeks of work now takes about an hour, and the attacker no longer needs a frontier model to pull it off. Ismail traces how most breaches begin, why phishing has become almost impossible to spot, and how a single poisoned dependency can cascade across an entire ecosystem. You'll get concrete steps any maintainer or developer can take today: switching package managers, enabling the security scanners that ship for free, and standing up an adversarial agent that hunts for chained exploits before an attacker finds them. Ismail also warns that the same instincts protecting enterprises may be quietly strangling open source itself. You'll hear why he thinks the big registries have dropped the ball, what a "Darwinian GitHub" would mean for anyone shipping a new package, and the one move he believes can keep the ecosystem alive.

Shane and Abhi break down the strangest model launch yet — Claude Fable 5, a Mythos-class model Anthropic said was too capable to release widely, until a US export-control directive made it vanish for everyone. We cover the whole arc: the launch hype, the pricing that had people spending $1,000 a day, the silent fallbacks to Opus, the system-prompt leak, and the snitch that triggered a 90-minute shutdown. Then a stacked back half — China's open-weight surge, OpenRouter Fusion, loop engineering vs loopcraft, the agent-learning gold rush, OpenAI filing to go public, and Dario's new essay. AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Mondays 12PM Pacific. 📚 READ MORE Claude Fable 5 launch: https://x.com/claudeai/status/2064394146916229443 Pokémon beaten with vision: https://x.com/Baconbrix/status/2064418858073784530 Export-control announcement: https://x.com/anthropicai/status/2065597531644743999 Amazon/WSJ report (Theo): https://x.com/theo/status/2065665304882209132 David Sacks on the ban: https://x.com/davidsacks/status/2065853007619588171 Token capital (Satya Nadella): https://x.com/satyanadella/status/2066182223213293753 Siri as a harness (Weinbach): https://x.com/mweinbach/status/2065630219021492474 MiniMax M3 open weights: https://x.com/minimax_ai/status/2065436935188058208 GLM 5.2: https://x.com/zai_org/status/2065704919299235870 Kimi K2 Code High Speed: https://x.com/kimi_moonshot/status/2066467110960959833 Cohere North Mini Code: https://x.com/cohere/status/2064378058329526556 Gemma 4 on consumer hardware: https://x.com/unslothai/status/2065433326706684135 Diffusion Gemma: https://x.com/unslothai/status/2065107734916432189 OpenRouter Fusion API: https://x.com/openrouter/status/2065856853989270011 AI SDK harnesses (Vercel): https://x.com/vercel_dev/status/2065509970775519569 Swyx on loopcraft: https://x.com/swyx/status/2065307558198567206 OpenEnv joins Hugging Face: https://x.com/ben_burtenshaw/status/2063991191415267492 Adaline 2.0 / agent learning: https://x.com/adiix_official/status/2066172819952566643 Cognition Frontier Code: https://x.com/cognition/status/2064061031912288715 Ramp SWE-bench: https://x.com/RampLabs/status/2065485806605619304 AWS on AI-generated code: https://x.com/awscloud/status/2064449711155589396 OpenAI files to go public: https://x.com/OpenAINewsroom/status/2065088002335158753 OpenAI acquires Ona: https://x.com/OpenAINewsroom/status/2064094175541461220 Salesforce acquires Fin AI: https://x.com/fin_ai/status/2066493998852686074 Mistral in talks to raise: https://x.com/business/status/2065420995393941692 Dario's essay on the AI exponential: https://x.com/DarioAmodei/status/2064781775247950326 📚 MASTRA RESOURCES Mastra: https://mastra.ai Mastra on X: https://x.com/mastra_ai Mastra Discord: https://mastra.ai/community/discord Mastra GitHub: https://github.com/mastra-ai Learn Mastra in the world's first MCP-Based Course: https://mastra.ai/course Principles of Building AI Agents (Book): https://mastra.ai/books/principles-of-building-ai-agents Patterns for Building AI Agents (New Book): https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA?
