Anthropic temporarily banned OpenClaw’s creator from accessing Claude

Peter Steinberger, the creator of the popular open-source AI agent framework OpenClaw, had his account for Anthropic's Claude model temporarily suspended on Friday. The ban, which Anthropic attributed to "suspicious" activity, was reversed within hours after Steinberger's post about the incident gained traction online. The event brings to light the growing friction between foundational model providers and the developers of third-party tools that build on their platforms, a situation complicated by Steinberger's recent employment at rival company OpenAI.

The suspension follows a recent policy change by Anthropic that directly affects OpenClaw users. The company stipulated that Claude subscriptions would no longer cover usage from "third-party harnesses," forcing users to pay for consumption directly through the API. Anthropic justified the move by citing the compute-intensive nature of agentic workflows. Steinberger, who claims he was complying with the new API-based payment rule when he was banned, had previously suggested the policy change suspiciously coincided with Anthropic adding new features to its own competing agent, Cowork.

This episode underscores the complex competitive dynamics shaping the AI ecosystem. When asked why he was using a competitor's model, Steinberger clarified that he was testing to ensure OpenClaw's continued compatibility for its users, separating his open-source work from his role at OpenAI. In a revealing comment about his decision to join OpenAI over Anthropic, he stated, “One welcomed me, one sent legal threats.” The incident also highlighted Claude's continued popularity among OpenClaw users, a market position Steinberger hinted he is now tasked with challenging, simply replying, “Working on that.”

This incident is a clear example of platform risk for open-source developers building on closed AI models. As model providers like Anthropic vertically integrate with their own applications, they can leverage API access and pricing policies to create a less hospitable environment for third-party tools, particularly those associated with direct competitors.
