Agents, Subtasks, Local RAG, MCP improvements, and more!

What's New

• Agents / Subtasks: You can now build agentic systems in Kiln! Any Kiln task can be made into a tool, allowing you to create a hierarchy of agents. See our docs for details
• Local + Open RAG: Our Search Tools / RAG system now supports local and open models. Use models like Qwen VL for extracting documents, and models like Gemma Embedding for embeddings.
• Save your Run Configuration & Set Default: Our Run tab now allows you to save a specific run configuration (model, prompt, parameters). This makes it easy to jump between configs. Set your preferred config as "Default", which will load automatically.
• Tools & MCP Updates: fixed a bug impacting some MCP servers on Windows, better error messages when a MCP servers errors
• New Models: Sonnet 4.5, GLM 4.6, GLM 4.5 Vision, Mistral Medium 3.1, Qwen 3 VL, Qwen 2.5 VL
• And More: UI improvements, faster tagging on large datasets, tagging UI shows all tags you've used, simplified onboarding, new intro
