Sam Altman announces major improvements to Codex, highlighting a new computer use capability that allows the model to control Mac applications in parallel without interfering with user workflows.

OpenAI's Codex has been significantly expanded with new capabilities including macOS app integration, multi-tool connectivity, image generation, action memory, and persistent task automation.

OpenAI releases a major update to Codex, enabling it to operate computers via cursor control, generate images, manage long-term tasks with memory, and deeply integrate with developer workflows like SSH and PR reviews.

Cloudflare and OpenAI have partnered to make OpenAI's frontier models, including GPT-5.4, directly accessible within Cloudflare Agent Cloud, enabling enterprises to deploy AI agents for real-world tasks at scale. The integration also includes Codex tools now generally available in Cloudflare Sandboxes and upcoming availability in Workers AI.

CyberAgent, a Japanese internet company, has adopted ChatGPT Enterprise and Codex as foundational AI technologies to accelerate business operations across advertising, media, and gaming divisions. The enterprise adoption addresses security, governance, and compliance concerns while enabling broader AI use across the organization.

OpenAI introduces flexible pay-as-you-go pricing for Codex on ChatGPT Business and Enterprise teams, removes rate limits, and lowers ChatGPT Business seat costs from $25 to $20 annually. The update aims to make Codex adoption easier for teams with promotional credits available for new users.

OpenAI announced its acquisition of Astral, a company behind widely-used open source Python developer tools including uv, Ruff, and ty, to integrate their tools with Codex and enhance AI-powered software development workflows. The acquisition aims to accelerate Codex's capabilities to assist developers across the entire development lifecycle.

OpenAI and Figma launch a seamless code-to-design integration using the Figma MCP Server, enabling developers to generate Figma designs from Codex and implement designs back into code with a bidirectional workflow.

OpenAI introduced a hybrid real-time access engine combining rate limits and pay-as-you-go credits for Codex and Sora, enabling users to seamlessly exceed rate limits by spending credits while maintaining system fairness and performance.

OpenAI describes an internal experiment building a production software product with zero manually-written code using Codex agents, achieving approximately 10x faster development with 1.5M lines of code written by AI in five months. The team learned that effective agent-driven development requires engineers to focus on systems design, scaffolding, and feedback loops rather than writing code directly.

OpenAI introduces GPT-5.3-Codex, an advanced agentic coding model that combines frontier coding capabilities with reasoning and professional knowledge, achieving state-of-the-art performance on SWE-Bench Pro and Terminal-Bench while being 25% faster than its predecessor.

OpenAI introduces the Codex App Server, a standardized protocol and architecture enabling developers to integrate Codex's agent capabilities across different products and IDEs. The system evolved from a practical harness reuse solution into a stable platform supporting rich interaction patterns like workspace exploration, streaming progress, and diff emission.

OpenAI introduces the Codex app for macOS (with Windows support added March 2026), a desktop interface for managing multiple coding agents in parallel, supervising long-running tasks, and collaborating on software development. The app features project-based threading, worktree support for conflict-free multi-agent work, skill extensions, and is available to ChatGPT Free/Go users with doubled rate limits on paid plans.

OpenAI publishes the first post in a series detailing how the Codex CLI agent loop works, explaining the core logic that orchestrates interactions between users, LLMs, and tool calls for software development tasks. The post covers inference, tool call execution, and the design decisions behind Codex's agent harness.

Cisco and OpenAI collaborated to transform Codex from a code completion tool into an enterprise-grade AI engineering agent capable of autonomous workflows at scale, achieving significant productivity gains including 20% build time reduction and 10-15× improvement in defect resolution throughput.
