Dec 1, 2024

December 2024 performance snapshot for shengxinjing/ollama. Key feature delivered: a unified image processing path across MLLama, Pixtral, and Qwen2VL by refactoring to a shared imageproc package, updating model-specific implementations to use shared utilities, and adding comprehensive tests for the new and refactored image processing functionalities. Documentation cleanup removed tutorials.md to eliminate references to deprecated content. Major bug fix addressed a crash in the /save command when message content contains quotes by wrapping content in triple double quotes when needed. Overall impact includes reduced duplication, improved reliability, and clearer docs, with test coverage enhancing maintainability and future refactors.
