			* extract & return thoughts in reasoning_content field (unless --reasoning-format) for DeepSeek R1 & Command R7B * tool-calls: add deepseek r1 template (models/templates/llama-cpp-deepseek-r1.jinja) + hackommodate broken official template * tool-calls: accommodate variety of wrong tool call opening tags both R1 Qwen 32B and 7B distills like to spit out * server/oai: ensure content is null when there are tool calls, and reasoning_content appears before content for readability * tool-calls: add DeepSeek R1 Qwen distills to server/README.md & server tests Co-authored-by: Georgi Gerganov <ggerganov@gmail.com> --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
