It is crucial to carefully examine claims of this nature. Automatic code generation via AI is a rapidly evolving field, but transforming millions of lines of code into stable and usable software is a complex challenge. Before accepting sensational claims, it is always advisable to verify the facts and analyze the supporting evidence.

For those evaluating on-premise deployments, there are trade-offs to consider. AI-RADAR offers analytical frameworks on /llm-onpremise to evaluate these aspects.
