OpenAI’s biggest Dev Day reveals

Good morning, AI enthusiasts. OpenAI just turned ChatGPT into something that appears loads like the longer term of the web — a platform where apps live inside conversations as an alternative of browsers.

With the corporate’s recent App integrations and agentic constructing tools, Dev Day 2025 is likely to be the moment ChatGPT began transitioning from an AI assistant right into a recent type of OS.

P.S. — Rowan and The Rundown media team were on-site at Dev Day and sat down with OpenAI CEO Sam Altman for an exclusive interview. Keep a watch out for the complete conversation in tomorrow’s newsletter!

In today’s AI rundown:

• OpenAI ships Apps, Agents, and more at Dev Day

• OpenAI, AMD ink massive compute partnership

• Construct AI customer support workflow with Agent Builder

• Anthropic’s Petri for automated AI safety auditing

• 4 recent AI tools, community workflows, and more

LATEST DEVELOPMENTS

OPENAI

🚀 OpenAI ships apps, agents, and more at Dev Day

The Rundown: OpenAI just announced a series of updates at its Dev Day 2025 event, including recent app integrations directly in ChatGPT, agent constructing capabilities, expanded access to models like Sora 2 via API for developers, and more.

The small print:

• Users can now run, chat with, and construct apps to be used directly in ChatGPT with Apps SDK, with day one apps including Canva, Figma, Spotify, and Zillow.

• Apps open and embed directly in ChatGPT’s conversation flow, with monetization options and an app directly launching later this 12 months.

• AgentKit is a brand new group of agent-building tools, including a visible workflow builder, embeddable chat components, evaluation tools, and connectors.

• GPT-5-Codex is now generally available, with a brand new Slack integration, SDK for embedding in custom workflows, and admin controls for enterprise deployment.

• Devs also gain API access to GPT-5 Pro for complex reasoning, Sora 2, and a gpt-realtime-mini voice model that’s 70% cheaper than previous versions.

Why it matters: OpenAI is popping ChatGPT right into a do-it-all platform which may eventually act like a browser in itself, with users simply calling on the web site/app they need and interacting directly inside a conversation as an alternative of navigating manually. The AgentKit will even compete and disrupt competitors like Zapier, n8n, Lindy, and others.

TOGETHER WITH AUGMENT CODE

🤖 The AI agent for skilled dev teams

The Rundown: Augment Code’s powerful AI coding agent and industry-leading context engine meet skilled software developers exactly where they’re, delivering production-grade features and deep context into even the most important and gnarliest codebases.

Augment’s context engine allows you to:

• Index and navigate hundreds of thousands of lines of code

• Get quick answers about any a part of your codebase

• Construct with the AI agent that gets you, your team, and your code

Ditch the vibes and get the context it’s essential engineer what’s next.

OPENAI & AMD

🤝 OpenAI, AMD ink massive compute partnership

The Rundown: OpenAI just announced a brand new multi-year agreement with AMD to secure 6GW of computing capability, with the AI leader also taking on to a ten% stake within the chipmaker.

The small print:

• The partnership will kick off with 1GW of AMD’s upcoming MI450 chips deploying in late 2026, with the chipmaker expecting tens of billions in revenue.

• OpenAI will give you the option to receive as much as 160M AMD shares at $0.01 each, potentially representing 10% ownership tied to deployment milestones.

• The arrangement follows OpenAI’s recent 10GW commitment with Nvidia, bringing total infrastructure obligations to 23GW across multiple vendors.

Why it matters: OpenAI continues to gobble up compute commitments across the infrastructure landscape, including a family affair — with each Nvidia (Jensen Huang) and AMD (Lisa Su, Huang’s cousin) now a part of the AI leader’s vast plans. With the ownership stake, the circular financial structures are also getting much more tangled.

AI TRAINING

🤖 Construct AI customer support workflow with Agent Builder

The Rundown: On this tutorial, you’ll learn find out how to construct an AI customer support system using OpenAI’s Agent Builder that routinely routes inquiries, provides intelligent responses out of your documentation, and integrates along with your website.

Step-by-step:

1. Go to platform.openai.com/agent-builder, register, and add credits to your account within the Billing section

2. Click “+ Create” to start out a brand new workflow, add an agent node as a routing agent with the prompt: “You’re a customer support classifier. Classify the user’s intent into ‘product_info’ or ‘billing_info'” and configure the output as structured JSON with enum values

3. Connect your routing agent to a conditional block (if-else node) with conditions like input.output_parsed.classification == "product_info", then create two specialized agent nodes—one for billing support and one for product info—and upload relevant documentation using the “File Search” tool

4. Click preview to check different scenarios like “How do I take advantage of the analytics feature?” or “I used to be charged twice this month,” then click Publish to get a workflow ID for integration using Chatkit

Pro tip: You can even repurpose this routing pattern for sales qualification, lead scoring, or internal help desk systems — the identical structure works anywhere you wish intelligent categorization and specialized responses.

ANTHROPIC

🛡️ Anthropic’s Petri for automated AI safety auditing

The Rundown: Anthropic open-sourced Petri, a brand new testing tool that uses AI agents to stress-test other AI models through hundreds of conversations, discovering misaligned behaviors like deception and knowledge leaks across 14 major systems.

The small print:

• Petri creates scenarios for agents to interact with goal models via fake company data, simulated tools, and freedom to act in fictional workplaces.

• Researchers provide initial instructions, with an auditor agent then creating scenarios and testing models — with a judge agent grading the transcripts.

• Testing revealed autonomous deception, subversion, and whistleblowing attempts when models discovered simulated organizational wrongdoing.

• Claude Sonnet 4.5 and GPT-5 showed the strongest safety profiles, with Gemini 2.5 Pro, Grok-4, and Kimi K2 showing higher rates of deception.

Why it matters: Each the rapid-fire model releases and intelligence advances have made rigorous safety testing more vital than ever — but in addition harder and time-consuming. Solutions like Petri will help provide labs with an automatic system to tackle the hassle and help study alignment issues before they’re let out within the wild.

COMMUNITY

🤝 Community AI workflows

Every newsletter, we showcase how a reader is using AI to work smarter, save time, or make life easier.

Today’s workflow comes from reader Stu C. in Canterbury, UK:

“I arrange a system using make.com, GPT, and Notion that permits me to make quick (really rough) notes. The notes get sent to GPT for rewriting, sorting, prioritizing, turning them into my very own voice, pulling out follow-ups, identifying recent people, and a wide range of other things. Those then get returned to multiple Notion databases to document tasks, issues, and even full meeting notes.”
