Same here. Since I started using LLMs a bit more, the killer step for me was to set up API access to a variety of providers (Mistral, Anthropic, Gemini, OpenAI), and use a unified client to access them. I'm usually coding at the CLI, so I installed 'aichat' from github and it does an amazing job. Switch models on the fly, switch between one-shot and session mode, log everything locally for later access, and ask casual questions with a single quick command.
I think all providers guarantee that they will not use your API inputs for training, it's meant as the pro version after all.
Plus it's dirt cheap, I query them several times per day, with access to high end thinking models, and pay just a few € per month.
