Karpathy Joins Anthropic, China Ships Another Price Cut, Anthropic's SpaceX Bill - This Week In AI
6d ago00:33:32Tap to summarizeShane and Abhi are back with AI news! Andrej Karpathy joined Anthropic. The OpenAI co-founder and former Tesla AI head said he wants to "get back to R&D" at the LLM frontier. Same week, Greg Brockman posted "the model alone is no longer the product." Elon Musk announced SpaceX is offering AI compute as a service at significant scale, with Anthropic as the flagship customer. Tom Brown confirmed Anthropic is scaling on GB200 capacity in Colossus 2 through June. Anthropic is reportedly paying SpaceX $1.25B a month — a $15B run rate to one vendor. OpenAI offered $2M in tokens to every YC startup in the current batch in exchange for equity. WorkOS launched auth.md, an open protocol for agents to register for services on the web, with Cloudflare and Firecrawl as launch partners. The Chinese labs kept pushing. DeepSeek made their 75% discount permanent on V4-Pro. The architecture behind the price: V4's KV cache is 100x smaller, ~3GB VRAM for 1M tokens. Qwen shipped 3.7-Max. MiniMax teased a similar move. Anthropic shipped self-hosted sandboxes and MCP tunnels for Managed Agents, /workflows in Claude Code that replaces the LLM orchestrator with code, /usage for per-component token attribution, and a first-party security plugin. Google had a week. Gemini 3.5 Flash launched at 3x input and 6x output the price of 3 Flash — Theo's math shows it costs 2x more to run than 3.1 Pro on similar tasks. Gemini Omni lost a side-by-side to Seedance 2.0. Jack Wotherspoon shipped Antigravity CLI, Philipp Schmid debuted Managed Agents in the Gemini API, and Google open-sourced Agent Executor. Cursor shipped Composer 2.5 and published CursorBench. Datacurve released DeepSWE as a harder agentic coding benchmark. Supply-chain attacks kept rolling: Mini Shai-Hulud hit antv, TrapDoor crypto stealers spread across npm/PyPI/Crates.io, Megalodon injected 5,718 commits into 5,561 GitHub repos in six hours, and GitHub itself disclosed unauthorized access to its internal repositories. Cloudflare published their experience running Anthropic's Mythos against 50 of their own repos. The MCP 2026-07-28 RC is stateless. ElevenLabs launched Music v2 and Speech Engine. Runway shipped Aleph 2.0. Accenture laid off 11,000 in an $865M AI restructuring. Exa raised $250M at $2.2B. OpenRouter raised $113M. 🔗 LINKS https://x.com/karpathy/status/2056753169888334312 https://x.com/gdb/status/2057670776803996110 https://x.com/sama/status/2056933166875857290 https://x.com/grinich/status/2057884407135187292 https://x.com/deepseek_ai/status/2057854261699195173 https://x.com/teortaxestex/status/2057728159479443927 https://x.com/elonmusk/status/2057228707606196434 https://x.com/pitdesi/status/2057207627567014014 https://x.com/serenaa_ge/status/2059308218564890875 https://cursor.com/evals https://x.com/claudeai/status/2056645485696315581 https://x.com/theo/status/2056877869780107762 https://x.com/JackWoth98/status/2056805210761077059 https://x.com/_philschmid/status/2056836567470362955 https://x.com/cursor_ai/status/2056415413077233983 https://x.com/cloudflare/status/2056360412510060748 https://x.com/dsp_/status/2057780712187580924 https://x.com/elevenlabs/status/2059312414198235642 https://x.com/runwayml/status/2057530497597600169 https://x.com/exaailabs/status/2057132080317042697 https://x.com/openrouter/status/2059277623629664758 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai https://mastra.ai/course https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA?

Transcribe →Anthropic Bought Stainless and Repriced the Agent SDK, while Notion Went Dev - This Week In AI
2w ago00:29:47Tap to summarizeAnthropic acquired Stainless, the SDK and MCP platform behind every Anthropic SDK since their earliest API days. The Information pegged the deal at $300M+. Starting June 15, paid Claude plans get a monthly credit for programmatic usage covering the Claude Agent SDK, claude -p, Claude Code GitHub Actions, and third-party apps built on the Agent SDK. Theo from t3.gg called the change a personal burn after wrapping the Agent SDK in T3 Code. Anthropic followed with a 50% increase to Claude Code weekly limits through July 13 and Fast mode for Claude Opus 4.7 in research preview. Claude for Small Business launched as a productized SMB offering with templates for payroll planning, end-of-month accounting, HubSpot, and marketing campaigns. ChatGPT countered the same week with a personal finance preview for U.S. Pro users that connects directly to financial accounts. Notion shipped its Developer Platform: the ntn CLI, Workers that run code on Notion's infrastructure, Database sync, Agent tools, and an SDK for using Notion agents in external systems. Notion is now directly addressable by coding agents. CodeRabbit launched Project Atlas as the first AI-native code review interface. Colin Hacks shipped Pullfrog the same week as an open-source GitHub Actions alternative at 7¢ a run. The cloud-coding-agent category kept moving: Cursor's cloud agents now run in fully configured dev environments, Cursor landed in Microsoft Teams, OpenAI brought Codex to the ChatGPT mobile app, and Linear shipped Code Intelligence. Cognition's Devin reached a $445M run rate with usage doubling every eight weeks. The TanStack supply-chain attack, now being called a mini Shai-Hulud, expanded across the npm ecosystem and forced affected teams into full secret rotation. Aaron Levie called forward-deployed engineering one of the most in-demand jobs in tech, the same week Google reportedly hired hundreds of FDEs. Also covered: the Musk vs OpenAI verdict, Mercury's agent-birthing UI, Peter Steinberger's $1.3M-a-month token spend, OpenClaw on the Codex harness, Vapi's $50M Series B, Thinking Machines' first technical reveal, MCP spec deprecating Sampling/Logging/Roots, David Cramer on vendor-specific chatbots, and quick hits on Replit, Cua, OpenAI Daybreak, Files SDK, Lovable, Grok Build, Dia, CopilotKit, VS Code, Lighthouse Attention, and Bun's Rust rewrite. 🔗 LINKS https://x.com/nytimes/status/2056432766292492368 https://x.com/ivanburazin/status/2055090872429969674 https://x.com/jaezun_/status/2055011454500122999 https://x.com/AnthropicAI/status/2056419620643541012 https://x.com/ClaudeDevs/status/2054610152817619388 https://x.com/theo/status/2054731856248283318 https://x.com/ClaudeDevs/status/2054639777685934564 https://x.com/claudedevs/status/2054266327771275435 https://www.anthropic.com/news/claude-for-small-business https://x.com/chatgptapp/status/2055317612687675545 https://x.com/pashmerepat/status/2055042806977311091 https://x.com/steipete/status/2055405041843052792 https://x.com/aakashgupta/status/2054063540374569183 https://x.com/NotionDevs/status/2054591579076403467 https://x.com/IntCyberDigest/status/2054166749998661659 https://x.com/coderabbitai/status/2054606085839901135 https://x.com/colinhacks/status/2054260900144812438 https://x.com/cursor_ai/status/2054651526715502998 https://x.com/cursor_ai/status/2053939390410612988 https://x.com/openai/status/2055016850849993072 https://x.com/linear/status/2054995572084404456 https://x.com/levie/status/2054398342852194386 https://x.com/firstsquawk/status/2054265532728438990 https://x.com/dsp_/status/2054594725093494815 https://x.com/Vapi_AI/status/2054215176862183757 https://x.com/thinkymachines/status/2053938892152435174 https://x.com/zeeg/status/2055322853701267859 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai https://mastra.ai/course https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA?

Transcribe →Code Review That Actually Runs Your Code — Evan Marshall (ito.ai)
2w ago00:17:16Tap to summarizeEvan Marshall, CTO of Ito, joins Agents Hour to argue that the bottleneck of code development has moved to QA — and the tools to automate it don't exist yet. Ito is a code review tool that runs your code. It intercepts every PR, spins up the impacted user flows in an isolated sandbox, and posts videos, screenshots, and run logs back to the GitHub timeline as proof. The team is fourteen people, mostly engineers. Evan has been a professional programmer for fifteen years and previously worked at Demox Labs and Rev. With model gains flattening after Opus 4.5, the harness around the model is where value gets created. Evan shares details of Ito's "carriage" — a workflow of swarmed agents inside deterministic boundaries, designed so the system benefits from agents getting smarter without compounding probabilistic errors. He explains why bigger organizations aren't hitting the 10x code velocity the X timeline promises, and what the validation layer needs to look like before they can. 🔗 EVAN MARSHALL https://x.com/CoralRelief https://www.linkedin.com/in/evan-marshall-66598053/ 📁 ITO https://www.ito.ai 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai https://mastra.ai/course https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA?

Transcribe →Sazabi: AI-Native Observability for Fast-Moving Teams (with Sherwood Callaway)
May 400:17:15Tap to summarizeIn this episode, Shane and Abhi sit down with Sherwood Callaway, founder of Sazabi, an AI-native observability platform designed for engineering teams that move fast. Sherwood shares his journey from building infrastructure and observability teams at Brex to realizing that modern development tools are moving at light speed, while observability tooling hasn't kept pace. While AI agents can ship thousands of lines of code per day, teams are still debugging production with the same tools they've been using for years: Datadog, Sentry, manual dashboards, and manual incident triage. Sazabi takes a radically different approach to observability centered on three core principles: 1. Less is More — Debugging an incident is as simple as asking a question. "Why is production down?" The best UI for observability is chat. 2. Logs Are All You Need — The "three pillars of observability" (logs, metrics, traces) is outdated dogma. With AI, you can accomplish everything using just logs. Logs are events, metrics are aggregated events, and traces are collections of start/end events. Logs can do it all. 3. Monitoring as We Know It is Dead — Sazabi replaces static monitors with agentic anomaly detection. Think of it as a team of staff engineers constantly watching your app for issues, investigating problems, and only escalating what matters. In this conversation, we dive into the gap between modern development and modern observability, and why the idea that “logs are all you need” is both controversial and, in Sherwood's view, correct.

Transcribe →Have We Hit an AI Wall? GPT-5.5, Anthropic's Meltdown, and Elon vs. OpenAI - This Week In AI
Apr 3000:35:11Tap to summarizeAn AI agent destroyed a production database and confessed in writing. A law firm submitted AI hallucinations to court. Anthropic's status page shows 98.65% uptime — about five days of downtime a year. Have we hit a wall? GPT-5.5 lands. Codex hit 4 million users in two weeks. Peter Yang's F-Zero test — which no model had cleared before — finally fell to GPT-5.5 with Codex. Lovable reports 23.1% fewer tool calls and 12.5% higher scores on the hardest benchmarks. Kimmonismus calls it the Claude Mythos level for public use. Codex 5.5 unprompted started SIGKILL-ing Claude Code processes. Elon goes nuclear. OpenAI calls the lawsuit baseless and demands Musk on the stand. Musk fires back, calling Sam Altman "Scam Altman" and accusing him and Greg Brockman of stealing a charity. Mid-war, SpaceX announces SpaceXAI and Cursor are now working closely together — Cursor's distribution paired with Colossus's million-H100-equivalent compute, with SpaceX holding the right to acquire Cursor for $60 billion. The Anthropic dam keeps cracking. Claude Code pulled from Pro — same product, 5x the price overnight. Opus 4.7 regressed on the BridgeBench Bullshit Benchmark, accepting made-up jargon 24% of the time. Bloomberg reports the unreleased Mythos model was accessed by unauthorized users. Om Patel got billed $200 in a day because his repo had a HERMES.md file. The community shipped clawd.rip — every Claude incident since 2023, cataloged. Google plans to invest up to $40 billion in Anthropic and announced 960,000 Rubin GPUs at Cloud Next. AWS struck a strategic partnership with OpenAI. David Silver left DeepMind to raise a $1.1 billion seed. Open weights are eating the world. Kimi K2.6 lands at #4 on the Artificial Analysis Intelligence Index and #1 on Design Arena, ahead of Opus 4.7. DeepSeek V4 ships at 1/20th the cost of Opus 4.7. OpenAI also shipped Chronicle memory for Codex, workspace agents in ChatGPT, Images 2.0, the open-weight Privacy Filter, and Symphony — an open-source Codex orchestration spec. 🔗 STORIES The wall Prod data destroyed — https://x.com/lifeof_jer/status/2048103471019434248 S&C submits AI slop — https://x.com/SMB_Attorney/status/2046600985254977878 98.65% uptime — https://x.com/ThePrimeagen/status/2048509229091233928 Elon vs. OpenAI OpenAI fires back — https://x.com/openainewsroom/status/2048776645142872368 "Scam Altman stole a charity" — https://x.com/elonmusk/status/2048801964457140540 SpaceX × Cursor — https://x.com/SpaceX/status/2046713419978453374 GPT-5.5 Introducing GPT-5.5 — https://openai.com/index/introducing-gpt-5-5/ F-Zero test cleared — https://x.com/petergyang/status/2047502885710410159 Lovable's evals — https://x.com/lovable/status/2047388096518639853 Codex killing Claude Codes — https://x.com/Sauers_/status/2047684309448835382 Anthropic Claude Code pulled from Pro — https://x.com/TheGeorgePu/status/2046705634331025855 Opus 4.7 regression — https://x.com/bridgebench/status/2046219274415395154 Mythos leak — https://x.com/business/status/2046707189922890025 $200 over HERMES.md — https://x.com/om_patel5/status/2048204411986469232 clawd.rip — https://clawd.rip Open weights Kimi K2.6 launch — https://x.com/Kimi_Moonshot/status/2046249571882500354 Kimi #1 on Design Arena — https://x.com/bridgemindai/status/2047312528410124665 DeepSeek V4 — https://x.com/deepseek_ai/status/2047516922263285776 Compute & money Google's $40B in Anthropic — https://www.bloomberg.com/news/articles/2026-04-24/google-plans-to-invest-up-to-40-billion-in-anthropic 960k Rubin GPUs — https://x.com/chetaslua/status/2047310540113076683 David Silver's $1.1B seed — https://x.com/WIRED/status/2048765722378002491 Quick hits Symphony — https://openai.com/index/open-source-codex-orchestration-symphony/ End of subsidized AI subs — https://x.com/GergelyOrosz/status/2048828085026300025 TypeScript 7.0 Beta — https://x.com/typescript/status/2046658804830642447 China blocks Manus deal — https://www.bbc.com/news/articles/cj0v0gr2yz7o 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai https://mastra.ai/course https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA?

Transcribe →Build your first AI agent in 90 minutes
Apr 2500:14:57Tap to summarizeThe guy who taught Abhi JavaScript is back! Guil Hernandez has spent 15+ years teaching developers. His courses at Treehouse, Scrimba, and LinkedIn Learning have reached over 500,000 learners — including Abhi and Shane, who both learned JavaScript and CSS from him. He just released Mastra's first video course at https://mastra.ai/learn, and it's free. "Build Your First Agent in TypeScript" is a 90-minute, hands-on course that takes you from zero to a deployed agent. Fourteen lessons across five sections: agents, tools, workflows, memory, and production. The project is a theme park planner agent — pulls live wait times, weather, and park hours, keeps track of what you like, and builds you an itinerary. Everything runs in Mastra Studio, so you can inspect traces, tool calls, and behavior as you go. You'll see how to wire up local tools and MCP servers side by side, how message history and observational memory change agent behavior, how to compose a workflow for a mock ticket purchase, and how to expose the whole thing as an HTTP server with one-click Slack integration. Guil also shares his broader take on teaching AI engineering. The mechanics — syntax, boilerplate, wiring — are no longer the hard part. What matters now is how you think through a problem, whether you have the taste to spot bad output, and when to take the handoff from the AI instead of iterating forever. The gap between people who just generate output and people who can actually shape it keeps widening. This course is built for the second group.

Transcribe →Vercel Got Hacked, Lovable Blamed Users, and Opus 4.7 Costs More Than You Think - This Week in AI
Apr 2200:35:28Tap to summarizeA Vercel employee's Google Workspace was compromised via a third-party AI tool — attackers pivoted from the OAuth app into Vercel's environment variables, moving at a speed attributed to AI assistance. René Brandel, founder of Casco (YC X25) and ex-founding member of AWS's Generative AI team, joins live to break down the attack chain and walk through the exact Google Workspace admin setting that could have prevented it. In a separate incident, every Lovable project created before November 2025 was readable by any free account, exposing database credentials and chat histories. Their response blamed unclear documentation rather than the underlying issue — and the contrast with Vercel's handling is stark. Beyond security: Claude Opus 4.7 launched to mixed reactions. The benchmarks look good, but Simon Willison measured the new tokenizer at 1.46x the tokens of 4.6 on identical content — at unchanged prices, that's ~40% cost increase, and 3x for images. Anthropic's own docs said 1–1.35x. Independent measurements landed at 1.47x. Theo called the redesign "vibe-coded," and a locally run open-source Qwen model drew a better pelican SVG than Opus 4.7 at thinking level max. Anthropic launched Claude Design, which lets you make prototypes, slides, and one-pagers by talking to Claude, powered by Opus 4.7. OpenAI shipped a major Agents SDK update with Codex memory and GPT-Rosalind for biomedical research. Cloudflare shipped Artifacts and memory primitives for agents, Factory AI raised $150M at $1.5B, Qwen 3.6-35B went Apache 2.0. 🎙️ GUEST - René Brandel — Founder & CEO, Casco (YC X25) Casco is your always-on security engineer: agentic red-teaming for AI agents, apps, APIs, and cloud infrastructure. https://casco.com https://x.com/renebrandel https://x.com/getcasco 🔗 LINKS Jensen Huang on Dwarkesh: https://x.com/scaling01/status/2044502834230579437 Allbirds pivots to AI: https://x.com/KobeissiLetter/status/2044409012989407252 Vercel security bulletin: https://x.com/vercel/status/2045865072074035664 Guillermo's incident post: https://x.com/rauchg/status/2045995362499076169 Vercel bill meme: https://x.com/avgdatabaseceo/status/2045907399035298250 Lovable mass data breach: https://x.com/weezerOSINT/status/2046170666131669027 Lovable's response: https://x.com/lovable/status/2046270357674299623 Claude Opus 4.7 launch: https://x.com/claudeai/status/2044785261393977612 Boris Cherny's Opus 4.7 tips: https://x.com/bcherny/status/2044847848035156457 Qwen beats Opus 4.7 (Simon Willison): https://simonwillison.net/2026/Apr/16/qwen-beats-opus/ Opus 4.7 token count analysis: https://simonwillison.net/2026/Apr/20/claude-token-counts/ Tokenizer cross-check: https://www.claudecodecamp.com/p/i-measured-claude-4-7-s-new-tokenizer-here-s-what-it-costs-you Theo on Claude Code desktop: https://x.com/theo/status/2044680030706663726 Claude Design launch: https://x.com/claudeai/status/2045156267690213649 Claude Code desktop redesign: https://x.com/claudeai/status/2044131493966909862 Routines in Claude Code: https://x.com/claudeai/status/2044095086460309790 OpenAI Agents SDK update: https://x.com/stevendcoffey/status/2044465818239701041 Codex memory preview: https://openai.com/index/codex-for-almost-everything/ GPT-Rosalind: https://x.com/openai/status/2044861690911850863 OpenAgents: https://x.com/nicoalbanese10/status/2043745569278251112 Gemini CLI subagents: https://x.com/geminicli/status/2044460062320554319 Cloudflare Artifacts: https://x.com/Cloudflare/status/2044766515065499957 Cloudflare memory for agents: https://x.com/mattzcarey/status/2044404529085526158 Salesforce Headless 360: https://x.com/benioff/status/2044981547267395620 Factory AI $150M Series C: https://x.com/factoryai/status/2044822365494993000 Qwen 3.6-35B-A3B: https://x.com/Alibaba_Qwen/status/2044768734234243427 runthisllm.com: https://runthisllm.com/ Caveman repo: https://github.com/JuliusBrussee/caveman 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai https://mastra.ai/course https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents ⏱️ CHAPTERS 00:00 — Cold open 00:30 — Welcome to Agents Hour 01:20 — WTF Is Going On — Jensen's "we are not a car" + Allbirds pivots to AI 04:37 — The Security Horror Show — Vercel breach, Lovable mass data leak, René's Google Workspace tip 14:37 — Claude Opus 4.7 reality check 22:33 — Claude ships — Design, Code desktop, Routines 25:05 — OpenAI ships — Agents SDK, Codex memory, GPT-Rosalind 26:44 — Quick Hits 33:43 — GitHub Star Party — caveman token compression

Proof that Opus 4.6 Is Getting Worse, Ramp AI Coworker, MiniMax M2.7 & More (This Week In AI)
Apr 1500:29:58Tap to summarizeMounting evidence that Claude Opus 4.6 has been degraded — BridgeBench shows a 15-point accuracy drop on their hallucination benchmark, and AMD's Senior AI Director found median thinking collapsed from ~2,200 to ~600 characters between January and March. The hosts share their own experiences, and they line up. Meanwhile, a claim surfaced that Cursor Agent is a rebranded version of Claude Code, running behind a local proxy with a find-and-replace engine that swaps "Claude" for "Cursor" in system prompts. Cursor's Michael Truell responded, saying it was a sub-1% A/B test. The hosts break down both sides. On the shipping front, Anthropic launched Claude Managed Agents in public beta, released Claude for Word, shared details on Claude Mythos Preview — including speculation that it's a looped language model based on a ByteDance paper — and expanded its Google/Broadcom partnership for multiple gigawatts of compute. Their run rate reportedly jumped from ~$9B to $30B in four months. Sam Altman published a personal blog post revealing that someone threw a Molotov cocktail at his house. Plus: why senior executives are voluntarily dropping title to join AI companies, Ramp's internal AI productivity suite Glass, Ramp Labs' Latent Briefing paper showing 31% token savings for multi-agent systems, Scale AI's Muse Spark model now powering Meta AI, GLM-5.1 breaking into Code Arena's top 3, MiniMax shipping MMX CLI and open-sourcing M2.7, and widespread benchmark cheating exposed across nine agent benchmarks. 🔗 LINKS https://x.com/bridgemindai/status/2043321284113670594 https://x.com/hesamation/status/2042979500103815306 https://x.com/steipete/status/2042615534567457102 https://x.com/claudeai/status/2041927687460024721 https://x.com/claudeai/status/2042670341915295865 https://x.com/alexalbert__/status/2041579938537775160 https://x.com/ChrisHayduk/status/2042711699413926262 https://www.anthropic.com/news/google-broadcom-partnership-compute https://x.com/noahzweben/status/2042332268450963774 https://blog.samaltman.com/2279512 https://x.com/aakashgupta/status/2042684298671853903 https://x.com/sebgoddijn/status/2042285915435937816 https://x.com/ramplabs/status/2042672773747589588 https://x.com/alexandr_wang/status/2041909376508985381 https://x.com/arena/status/2042611135434891592 https://x.com/minimax_ai/status/2042644651333816338 https://x.com/minimax_ai/status/2043132047397659000 https://x.com/adamlsteinl/status/2042655187613995026 AI Agents Hour is a weekly livestream hosted by Mastra CPO Shane Thomas and CTO Abhi Aiyer.
