OpenAI’s biggest dev day ever

Together with

Good morning, AI enthusiasts. OpenAI unveiled AgentKit at Dev Day—a visual builder that lets companies create AI agents without complex coding, already helping Klarna automate two-thirds of customer support.

Will this platform approach make OpenAI the dominant force in enterprise AI, or will competition keep the field open?

In today's recap:

• OpenAI launches visual agent builder and apps inside ChatGPT

• AMD partnership brings 6 gigawatts of computing power to OpenAI

• Anthropic open-sources Petri for automated AI safety testing worldwide

OpenAI Dev Day: Apps, agents and more tools

Recaply: OpenAI hosted its biggest Dev Day yet on October 6, 2025, unveiling a suite of powerful new tools that transform how developers build with AI. The company announced apps that work inside ChatGPT, a visual agent builder called AgentKit, and made its advanced GPT-5 Pro model available through its API. CEO Sam Altman demonstrated how these updates help developers create software in minutes instead of months. With over 800 million weekly ChatGPT users, these tools open massive opportunities for developers worldwide.

Key notes:

• Apps now run directly inside ChatGPT conversations with partners like Spotify, Zillow, Canva, and Figma going live immediately using the new Apps SDK built on Model Context Protocol.

• AgentKit offers a visual canvas for building AI agents without complex coding, helping companies like Klarna handle two-thirds of support tickets automatically.

• GPT-5 Pro joined the API with 400,000 context tokens and advanced reasoning capabilities, though it costs significantly more at $15 per million input tokens.

• Sora 2 became available in API preview, letting developers generate videos with synchronized audio and speech capabilities.

• Codex reached general availability with Slack integration and a new SDK, showing 70% more pull requests merged weekly at OpenAI.

Impact: OpenAI's Dev Day announcements signal the company's aggressive push to become the dominant platform for AI development. By making agent building visual and embedding apps directly into ChatGPT's 800 million user base, OpenAI positions itself against competitors like Anthropic and Google while creating new revenue streams for developers. These tools lower barriers to AI development, potentially democratizing access to powerful capabilities.

OPENAI & AMD

OpenAI, AMD sign massive chip contract

Recaply: OpenAI just made a huge move by partnering with AMD to power its future AI systems. The deal involves deploying 6 gigawatts of AMD's powerful Instinct GPUs over several years. This massive agreement kicks off in late 2026 with 1 gigawatt of AMD's newest MI450 chips. The partnership shakes up the AI hardware world, giving AMD a major role in building the infrastructure behind ChatGPT and other OpenAI products.

Key notes:

• OpenAI will deploy 6 gigawatts of AMD GPUs through a multi-year, multi-generation agreement starting with MI450 series chips in the second half of 2026.

• AMD granted OpenAI warrants for up to 160 million shares (roughly 10% ownership) that vest as deployment milestones are reached.

• The deal is expected to generate tens of billions in revenue for AMD over the partnership duration.

• AMD shares jumped over 34% on Monday following the announcement, signaling strong investor confidence.

• This marks AMD's biggest AI partnership to date and positions the company as a core compute partner alongside Nvidia.

Impact: This partnership signals a major shift in AI infrastructure. OpenAI is diversifying beyond Nvidia to meet growing compute demands, while AMD gains credibility as a serious player in AI chips. The deal shows how companies are racing to build massive data centers to keep up with AI's explosive growth. For everyday users, more competition in AI hardware could mean faster innovation and better AI tools down the road.

ANTHROPIC

Anthropic releases Petri for AI safety

Recaply: Anthropic just open-sourced Petri, a free tool that helps researchers spot risky behavior in AI models before things go sideways. Think of it as a safety inspector that runs thousands of test conversations with AI systems to catch problems like deception or power-seeking tendencies. The company tested 14 major AI models and found Claude Sonnet 4.5 came out as the safest option, though even it showed some concerning behaviors.

Key notes:

• Petri automates AI safety testing through simulated multi-turn conversations with target models.

• The tool tested 14 frontier models across 111 scenarios checking for deception, sycophancy, and self-preservation behaviors.

• Claude Sonnet 4.5 scored as the lowest-risk frontier model, slightly outperforming GPT-5.

• Researchers can test AI behavior hypotheses in minutes instead of weeks of manual work.

• The UK AI Security Institute already used a pre-release version to build evaluations for Sonnet 4.5.

Impact: Petri represents a shift toward making AI safety testing accessible to everyone, not just tech giants with massive resources. As AI systems gain more autonomy and power, having open tools to catch misalignment early becomes essential for the entire industry.
