What is OpenAI Codex?

OpenAI Codex is an AI tool designed for coding tasks that is integrated into the ChatGPT platform. It allows users to generate and interact with code using natural language. OpenAI provides access to this capability through both the standard web interface and a dedicated command-line interface for developers.

Is OpenAI Codex available for free?

Yes, OpenAI confirmed that Codex remains available on the ChatGPT Free plan. While running advanced coding models requires significant computational power, the company stated that its current infrastructure and model efficiency allow them to continue offering access to the tool without requiring a paid subscription for basic use.

Which ChatGPT plans include access to OpenAI Codex?

OpenAI Codex is included in both the ChatGPT Free and the $20 per month ChatGPT Plus plans. Although OpenAI recently launched a $100 Pro tier for users with high compute demands, the company intends to keep Codex accessible to its broader user base on the standard consumer tiers.

OpenAI Maintains Free and Plus Access for Codex Coding Agents

OpenAI confirmed that Codex will remain available on both the ChatGPT Free and ChatGPT Plus ($20/month) plans. This follows the launch of a $100 Pro tier for heavy users, which sparked concerns that the company might restrict its flagship agentic coding (AI that autonomously writes and debugs code) tool.

The announcement signals a strategic push for market share as competitors like Anthropic begin testing changes to their prosumer tiers. By highlighting its efficient models and compute capacity, OpenAI is positioning its stack as the stable choice for developers who rely on autonomous workflows without the threat of price hikes.

You can continue using Codex for multi-step engineering tasks within your existing subscription without needing to upgrade to usage-based seats. While the company plans to engage with the community before making changes, the current access levels for the web interface and CLI remain unchanged for all users.
