Anthropic's 2021 roadmap sparks a look back at AI tool use

A poster looking at Anthropic's 2021 roadmap says the company was early on reinforcement learning and tool use. They suggest two pre-training terms, “periodic batched backprop” and “skeletokenization,” might correspond to papers they link. In a reply, another commenter points to a LaMDA paper mentioning tool use in January 2022 as an example of how old the concept is.
