New release of LLM adds support for reasoning traces, OpenAI Responses, server-side tools, and smarter logging
LLM remains the default Swiss-army knife for developers who want one CLI across model providers, and this release keeps it current with the two biggest API shifts of the year: reasoning traces and Responses-style tool calling. Worth updating if you script against multiple providers, since it saves you from writing provider-specific glue code yourself.
