- Reads PDFs and documents
- Thinks step by step on hard questions
What people use it for
Produce and review code snippets
Generate complete functions, unit tests and small modules from a short spec, then ask for line-by-line explanations and targeted fixes. Review and refactor code with concrete diffs you can paste back into your editor.
Multi-file debugging with context
Feed project files or stack traces and get prioritized error causes and step-by-step reproduction instructions. The model holds long context so it can track cross-file state across the session.
Long-form technical summaries and documents
Summarize design notes, convert research into structured sections, or extract exact tables and JSON from long documents or mixed text and images. Ideal for reports that must preserve structure across many pages.
Why it is worth it
- Multimodal input: understands images and files for visual debugging and document extraction.
- Large dense context: keeps long drafts, logs, and code bases in memory for coherent outputs.
- Designed for agent use: reliable tool calls and step-wise reasoning for multi-step tasks.
- Consistent structured output: JSON, tables or code blocks suitable for downstream automation.
