Today: OpenAI is giving developers the infrastructure behind Codex, allowing agents to run code, use tools, coordinate subagents, and continue working across long sessions. Plus, DeepSeek introduces a more efficient model, V0 builds apps from prompts, and GPT‑Rosalind expands globally.
Let’s get into it 👇
OpenAI launches an API for building agents that work for days
OpenAI introduced the Agents API in public beta, giving developers the same managed harness and infrastructure that powers Codex. A single API call can create an agent that runs code, works with files, uses tools, and saves results across long sessions.

Developers can use OpenAI-hosted sandboxes or their own infrastructure, while built-in context management keeps agents working across multiple context windows. The API also supports MCP tools and parallel subagents, with no additional fee beyond the tokens and tools used.
