Disney drops Microsoft’s GitHub Copilot, shifts to OpenAI’s Codex for coding
Disney will stop using GitHub Copilot and several other AI coding assistants in the U.S. this August, opting to adopt OpenAI’s Codex instead.
Disney has announced that, beginning in August, it will cease using Microsoft’s GitHub Copilot and two Amazon AI coding products for its U.S. engineering teams, according to an internal memo seen by one outlet. The firm will keep Anthropic’s Claude Enterprise and the Cursor tool, but will transition to OpenAI’s Codex for future development work, without specifying a launch schedule. Staff feedback indicated that Copilot was rarely employed, with some engineers finding its code unnecessarily intricate and opting for alternatives like Cursor and Kiro.
Recent pricing adjustments by Microsoft, moving to a token-based model, added to user frustration. Disney’s internal AI adoption dashboard shows heavy reliance on Claude and Cursor, underscoring the company’s focus on accelerating development speed. The move highlights the competitive pressure on Microsoft’s AI suite from rivals such as OpenAI and Anthropic.
Why it matters
The shift shows how major media firms are re-evaluating AI tools to boost developer productivity and cut costs.
