This talk details Jane Street's approach to integrating large language models (LLMs) into their developer workflow, focusing on overcoming challenges posed by their unique technology stack, particularly their extensive use of OCaml. The core thesis is that building custom LLM solutions, including fine-tuned models and tailored editor integrations, is necessary to maximize value when off-the-shelf tools are insufficient due to specialized languages and internal development environments.
