# OpenAI DevDay 2026 Recap for Developers

Tier C (Weak signal): InfoQ news recap that relays OpenAI's DevDay 2026 announcements with a few community reactions; it adds no facts beyond the vendor's own releases.

Summary based on the full text.

## In short

An InfoQ summary (October 2026) of OpenAI's DevDay 2026. The announcements: GPT-6.1 Sol, which OpenAI says approaches GPT-6 Astra on several evaluations at one-fifth of Astra's price; computer use and multi-agent features in the Agents API; Codex running in cloud environments with a code-review workflow and Codex Security Cloud; a Decisions API for picking from predefined answers; an expanded ChatGPT plugin system with MCP Events; Dots, persistent agents; and ChatGPT Space, a shared workspace for teams and agents.

## Key numbers

- one-fifth: GPT-6.1 Sol price relative to GPT-6 Astra's standard input and output token prices, per OpenAI
- $0.10: price per million cached input tokens for GPT-6.1 Sol

## What it reports

- GPT-6.1 Sol: an update aimed at coding, computer use and professional tasks; cached input at $0.10 per million tokens; available in the API, ChatGPT Work and Codex.
- Agents API: computer use through graphical interfaces, Codex multi-agent features, tool search, context compaction, with OpenAI running the execution infrastructure.
- Codex: cloud environments, voice input and an /agents interface in the CLI, pull-request review for GitHub and GitLab, and a security scanner that prepares fixes.
- Decisions API (limited preview): uses the smaller Luna model for classification, routing and choosing an agent's next action.
- Plugins: sidebars, interactive panels, custom file viewers, and event-triggered automations via the proposed MCP Events specification.
- Community reaction was split between interest in computer use, cloud Codex and cheaper models, and doubt that the releases go beyond existing agent platforms.

## How they got it

Secondary reporting of OpenAI's announcements plus selected social-media posts. Saved by design because openai.com blocks fetchers.

## Limits

- Relays vendor claims; no benchmarks, prices beyond two figures, or independent tests.
- Community quotes are anecdotal.
- Readers should check OpenAI's own release notes for details.

## Why it matters for companies

The direction is the useful signal: OpenAI is moving from single model calls toward persistent agents that run on its infrastructure, operate software and share a workspace with teams. That shifts procurement questions toward where agent execution happens, what data it touches and how actions are logged. The Decisions API is a small, practical pattern worth copying with any provider: use a cheap model to route and classify against a fixed set of options.
