OpenAI announced a free version of ChatGPT designed specifically for teachers on 19 November 2025 [source]. The offering includes access to GPT-4o, the company's most capable model, alongside features such as canvas for collaborative editing and advanced voice mode.

The announcement states that teachers can use the tool to generate lesson plans, create quizzes, and provide feedback on student writing. OpenAI positions the release as part of its effort to support educators, citing partnerships with organisations including the American Federation of Teachers and Common Sense Media.

The free tier for teachers removes the usage caps typically applied to GPT-4o in the standard free ChatGPT product. Teachers must verify their status through an unspecified process to access the offering. OpenAI did not disclose whether usage data from teacher accounts will be used for model training, nor whether student data protections apply when teachers use the tool to process classroom materials.

The company also announced a curriculum resource called "ChatGPT Edu Foundations" intended to help educators integrate AI tools into instruction. Materials include sample prompts and guidance on evaluating AI-generated content.

This release follows OpenAI's August 2024 launch of ChatGPT Edu, a paid enterprise product for universities. The teacher-focused free tier represents an expansion into K-12 education without the institutional licensing model.

No technical specifications were provided regarding how the teacher version differs from standard ChatGPT beyond the removal of usage limits. The announcement did not address concerns raised by education researchers about accuracy of AI-generated educational content or the implications for student assessment integrity.
