March 2026 monthly summary: Delivered reliability, clarity, and configurability across LiteRT-LM and Gallery. Key features include Tool Response Typing in Conversation to standardize response metadata and support downstream processing (commit e35abb74), extraContext support for C API Conversation messages enabling richer context (commit 41d6b964), and memory-safety improvements through Conversation destruction order fix to prevent dereferences during background-task teardown (commit d490099). In Gallery, implemented thinking mode for LLM configurations and user-visible thinking UI via a new ChatMessageThinking type to display agent thought process (commits 15a7e8ee and 9a5e1930). UI/UX and onboarding improvements include the ConfigDialog min tokens display enhancement and a dedicated Initializing Model screen on first load (commits bfd6a633 and 8629bab0). These changes collectively improve reliability, data quality, configurability, and user experience, enabling safer operations, better analytics, and faster model iteration.
