I Built primarily using models from @AnthropicAI. However, I’m now completely unable to use any of the models to continue working on this app due to the extremely aggressive censorship and “guardrails” implemented. I have a premium subscription to Claude Code and Cursor. I’m curious to know if @cursor_ai or @AnthropicAI can provide a solution to allow me to continue using Anthropic models to develop legitimate security software products. Alternatively, I’d appreciate any recommendations you may have.
