“Why would the open weights providers need their own tools for agentic workflows when you can just plug their OpenAI-compatible API URL into existing tools?”

“It's crazy how often this happens. For a tool that's usualy so hesitant to create "offensive" content, AI sure will throw that out the window if you give it a "persona" it can follow.”
