I wrote the first lines of AIA three years ago. Back then it was just a front end to a Rust CLI called mods – it managed prompt text files and piped them into mods, which talked to OpenAI’s GPT. Today AIA handles 20+ providers and hundreds of models on its own. Prompt files are now markdown with YAML front matter, shell integration, and ERB.

AIA has a batch mode for running prompts non-interactively and a chat mode for conversation. You can run a prompt against one model or several at once. The part I find most useful: throw the same prompt at multiple models, see the responses side by side with their costs, and pick the cheapest one that gives you a good enough answer.
