OpenAI maintains a public livestream archive that strings together every product reveal since late 2025. Developers can replay sessions on topics ranging from the ChatGPT Atlas launch to the GPT-5 debut, with each video hosted on the company’s blog. The collection serves as a one‑stop reference for engineers tracking the evolution of OpenAI’s API offerings for free to the community.

Earlier this year, gpt-realtime was introduced, a low‑latency model designed for production voice agents, and the Realtime API updates cut response times by half. The same month saw the rollout of GPT‑4.1 in the API, delivering higher token limits and improved reasoning. These tools enable developers to embed conversational AI into interactive products with minimal overhead.

Beyond model upgrades, OpenAI added new agent‑building primitives in March, allowing developers to define tool use and memory management via concise JSON schemas. Coupled with the 4o image generation release, the platform now supports multimodal pipelines that blend text, image, and audio in a single request. The archive demonstrates how OpenAI’s incremental releases have steadily broadened the practical scope of generative AI.
