Deep reasoning model controls, multimodal document chat with embedded images, verified inline citations, and Google Ads integration.

See what’s new and improved in our latest update.

### Reasoning & Thinking Parameters for AI Models

* Configure advanced reasoning and thinking parameters across supported models (including Byteplus and frontier LLMs) to handle rigorous cognitive tasks.
* Adjust reasoning budgets and chain-of-thought depth for intricate data analysis, financial modeling, and complex coding workflows.
* Provides complete transparency into model thinking steps during interactive chat and automated flow execution.

### Multimodal Vector Chat & Embedded Image Q\&A

* AI chat now extracts and understands visual assets embedded inside uploaded documents, including financial graphs, architecture diagrams, and infographics.
* Ask visual questions such as *"What does the Q3 revenue trend show on page 14?"* without manually cropping or extracting images.
* Bridges the gap between structured text retrieval and visual comprehension in RAG knowledge bases.

### Precise Inline Citations & Sentence Highlighting

* Every generated AI answer now includes interactive, clickable citation tags directly adjacent to referenced facts.
* Clicking a citation opens the document viewer and instantly navigates to the exact page, highlighting the source sentence in bright yellow.
* Eliminates AI hallucinations by providing immediate visual verification for compliance, legal, and operational teams.
