- Optimized for conversational templates and chat-style prompts
- Retrieval-Augmented Generation (RAG) with grounding spans and citation modes
- Single-step and multi-step tool use templates for orchestrating external tools/APIs
- Multilingual generation (trained on 23 languages; evaluated in 10 languages)

Best for
- Document Q&A with RAG: Build systems that retrieve relevant document snippets (e.g., from a vector store) and produce citation-aware answers over long documents or corpora.
- Conversational Agents that Call Tools: Implement chat agents that call external APIs, databases, or tools in single-step or multi-step workflows to complete tasks like booking, data retrieval, or automation.
- Multi-step Automation Pipelines: Orchestrate sequences of tool invocations (e.g., search → extract → transform → submit) where the model plans and executes multiple steps to complete complex operations.
- Long-form Summarization and Analysis: Summarize, synthesize, or analyze very long documents, meeting transcripts, or multi-document corpora using the extended context window.
- Multilingual Support and Cross-Language Tasks: Provide question answering, summarization, or conversational support across numerous languages with evaluated performance in major languages.
- Research and Experimentation: Use the open-weights release to experiment with grounded generation techniques, citation modes, prompt templates, and custom tool-use strategies in research or prototype builds.
- Long-form document question-answering and summarization using RAG over large corpora
- Multi-step automation and agents that call and combine external tools/APIs
- Conversational assistants requiring grounded answers with source citations
- Document analysis pipelines (PDFs, knowledge bases) combined with semantic search like FAISS
- Multilingual customer support and knowledge retrieval across large contexts
