AI-Generated Summary
Key Takeaways
- ✓Responses API Architecture: The new API operates as a strict superset of chat completions and assistants, supporting both stateful and stateless modes. Developers can pass store false for stateless operation while maintaining backward compatibility. OpenAI stores state free for thirty days, enabling visual debugging through the dashboard where developers can inspect prompts, tool calls, and configurations without additional cost.
- ✓Web Search Implementation: GPT-4o search preview uses synthetic data techniques and O-series model distillation to achieve 90% accuracy on Simple QA versus 38% for base GPT-4o. The model provides paragraph-level citations and combines with structured outputs to create an API for the internet, enabling developers to extract web data into custom JSON schemas in real-time for application integration.
- ✓File Search Strategy: Developers use file search as a managed RAG service for storing user preferences and company documents, avoiding the complexity of building custom chunking and embedding strategies. Metadata filtering enables efficient retrieval once vector stores exceed five to ten thousand records. The tool works alongside web search in single API calls to combine private data with real-time information.
- ✓Computer Use Model: The computer use tool operates as a separate fine-tuned model that processes screenshots and outputs actions including clicks, scrolls, and typing. Tasks can span multiple minutes with twenty-plus steps, representing early-stage capability comparable to GPT-1 or GPT-2 level maturity. Developers can automate browser-based workflows for end users through the Responses API integration.
- ✓Agents SDK Evolution: The production-ready SDK adds TypeScript support, guardrails for parallel execution blocking, and multi-provider tracing that defaults to OpenAI dashboard but supports third-party observability tools. The handoff pattern enables triage agents to route requests to specialized agents, with full trace visibility replacing monolithic agents with numerous tool calls that prove difficult to monitor and debug.
What It Covers
OpenAI launches the Responses API, merging chat completions and assistants capabilities into one unified endpoint. The release includes three built-in tools: web search with GPT-4o search preview model achieving 90% accuracy on Simple QA, improved file search with metadata filtering, and computer use for browser automation. The Agents SDK upgrades the experimental Swarm framework with production-ready features.

Notable Moment
Roman revealed that anything supporting the chat completions API format can plug into the Agents SDK, not just OpenAI models. This architectural decision enables developers to use any provider while maintaining access to OpenAI's tracing infrastructure and orchestration patterns, creating an open ecosystem rather than a locked-in platform approach for multi-agent workflows.
Episode Transcript
Hey, everyone. Welcome back to another Latent Space lightning episode. This is Alessio, partner and CTO at Decibel, and I'm joined by SpooX, founder of Small AI. Hi. And today we have a super special episode because we're talking with our old friend, Roman. Hi. Welcome. Thank you. Thank you for having me. And Nikunj who is most famously is if anyone has ever tried to get any access to anything on the API, Nikunj is the guy. So I I know I know I know your emails because I look forward to them. Yeah. Nice to meet all of you. Yeah. I think that we're basically convening today to talk about the new API. So perhaps you guys wanna just kick off, what is opening and launching today? Yeah. So, I can kick it off. We're launching a bunch of new things today. We're gonna do three new built in tools. So we're launching a web search tool. This is basically chat GBD for search, but available in the API. We're launching, an improved file search tool. So this is you bringing your data to OpenAI. You upload it. We, take care of parsing it, chunking it, embedding it, making it searchable, give you this like ready vector store that you can use. So that's the file search tool. Then we're also launching our computer use tool. So this is the tool behind the operator product in Chat GPD. So that's coming to developers today. To support all of these tools, we're going to have a new API. So we launched chat completions like I think March 2023 or so. It's been a while. So so we're looking for an update over here to support all the new things that the models can do. And so we're launching this new API called the responses API. It is, you know, it works with tools. We think it'll be, like, a great option for all the future agentic products that we build. And so that is also launching today. Actually, the last thing we're launching is, the agents SDK. We launched this thing called Swarm last year where, you know, it was an experimental SDK for people to do multi agent orchestration and stuff like that. It was supposed to be like educational experimental, but like people people really loved it. They like ate it up. And so we are like, alright, let's let's upgrade this thing. Let's give it a new name. And so we're calling it the agents SDK. It's gonna have built in tracing in the OpenAI dashboard. So lots of cool stuff going out. So yeah. Sorry about that. That's a lot. But we said 2025 was a year of agents. So there you have it. Like, a lot of new tools to build these agents for developers. Okay. I guess I guess we'll just kinda go one by one and we'll leave the Aegis SDK towards the end. So responses API, I think the sort of …
