OpenAI Agents API in 10 steps: GPT-6.1 Sol nears GPT-6 Astra at one-fifth the price
Roger_M_Taylor · x · 2026-10-05
An OpenAI engineer's walkthrough shows how to run agents without building the loop yourself: pick GPT-6.1 Sol (launched at DevDay Sep 29, near GPT-6 Astra on agentic coding/computer use at 1/5 price), create a session via client.beta.agents.sessions.create(), choose hosted (Codex/ChatGPT sandbox infra) or self-hosted runtime, plug in MCP servers, functions, web search and computer use, and cut tool costs with tool search and programmatic tool calling. The quoted article argues DevDay quietly assembled most of an 'agent operating system.'
