Where they differ most
Europe
OpenAI offers data and inference residency in Europe for new ChatGPT Enterprise and Edu workspaces at no extra cost. The Codex app and CLI are covered; Codex Web is not. Anthropic's Team and Enterprise pages we checked state no EU option.
Zero data retention
OpenAI says local computer access with Work Cloud does not provide strict zero data retention. Anthropic offers zero data retention for Claude Code to qualified Enterprise accounts through the account team.
Usage on Enterprise
ChatGPT Enterprise with flexible pricing has no fixed rate limits and draws on credits. Claude Enterprise charges the seat plus usage at API rates.
Choose OpenAI Codex or Claude Code
Choose OpenAI Codex if
- Your company already runs on ChatGPT Business or Enterprise.
- You need data and inference residency in Europe and can start a new Enterprise workspace.
- Your developers prefer OpenAI's GPT models.
Choose Claude Code if
- Your developers prefer Claude models and Anthropic's own agent.
- You need zero data retention for coding sessions on Enterprise.
- You want published spend limits per member on the Team plan.
A third option for companies
If you would rather not pick one model vendor for every developer, Standard Compute is a third option. Point Claude Code at Standard Compute and your team stops hitting 5-hour and weekly caps: agents run until the monthly budget is used, with Claude, GPT, Gemini and open models through one API.
Cost per step
Each step goes to the cheapest model that can do it and the cheapest provider fast enough to serve it.
Models
Claude, GPT and Gemini alongside open models such as GLM, DeepSeek, MiniMax and Kimi, through one API.
Processing in Europe
A Europe rule per company, team or key: every request, including retries and fallbacks, is served only by approved European inference endpoints, or refused before your prompt is sent.
Zero data retention
Required per company, team or key, and Standard Compute never trains on your prompts or outputs.
Single sign-on
Microsoft Entra ID or any SAML provider, and Claude Desktop and Claude Code sign-in with a Microsoft work account.
Budgets
A fixed monthly budget per person and app that never overruns, and spending caps per key and for the whole company.
Allow-lists
Approved providers per company, team or key, and approved models per key. Fallbacks never route around them.
Audit log
Admin changes with before and after values, and a 12-month export of every request's model, provider and region rule.
