Updates to Codex usage on Plus
The powerful code-generation model is now included at no extra cost for paying users.
OpenAI has made a significant change to the accessibility of its Codex model, the powerful AI system that underpins GitHub's Copilot. Previously, developers needed to pay for API calls to use Codex separately. Now, the company has announced that Codex usage is included at no additional charge for all users with an active ChatGPT Plus subscription. This effectively bundles advanced code-generation capabilities into the existing $20/month plan.
This move lowers the barrier to entry for developers and startups looking to build custom coding assistants or integrate AI-powered code completion into their own software. By removing the per-request cost, OpenAI is encouraging more experimentation and integration of its code models. It also represents a strategic bundling of services, making the Plus subscription more valuable as it now encompasses both conversational AI (GPT-4) and specialized code-generation AI (Codex) under one flat fee.
- Codex API access is now free for ChatGPT Plus subscribers, removing pay-per-call fees.
- The model is the engine behind GitHub Copilot, a leading AI pair programmer.
- This change lowers costs for developers building custom coding tools and integrations.
Why It Matters
Reduces development costs and accelerates the creation of new AI-powered coding tools and assistants.
