An update on Anthropic model access in Ona

Name: Ona
Author: Ona

What is changing now for Ona Cloud and enterprise customers

Today, Anthropic told us it intends to end Ona's access to its models sometime this week. It did not provide a firm date. Anthropic linked its decision to OpenAI's planned acquisition of Ona.

The transaction has not closed, and Ona remains independent. But we expect Anthropic model access to end before the transaction is complete.

We do not want customer workloads depending on an uncertain deadline, so we are acting now.

Effective immediately, our Anthropic harness, until now called Ona Agent, will no longer be available in Ona Cloud with Ona-managed model access. New environments will no longer offer this option.

Existing automations will move automatically to the closest equivalent OpenAI model. No action is required.

Enterprise customers who bring their own Anthropic API key using Ona's Anthropic harness can continue to do so today. Anthropic has not asked us to disable BYOK access, but we are not confident that will remain the case.

We therefore strongly recommend that these customers move to the open-source Codex harness, which Ona supports as a first-class experience. Our team will help customers make the transition.

Choice has been part of Ona from the beginning. Customers can run the agent harness that works best for them in an Ona environment, including Claude Code, Codex CLI, OpenCode, and others. We have invested in first-class support for both the open-source Codex harness and our Anthropic harness.

We are sorry for the short notice.

As we prepare to join OpenAI, our commitment to choice will not change. We believe the best tools should win through quality and value, not because customers are locked in or competitors are locked out.

Codex is open source, runs anywhere, and supports models from multiple providers. We look forward to building with a partner that shares our belief in open competition and customer empowerment.
