Chat Mode vs. Reasoning Mode

May 8, 2025

What is Reasoning Mode?

Reasoning Mode is Otto™’s advanced setting powered by reasoning models, designed for deep, multi-step thinking before presenting a final answer.

Rather than responding immediately like in Chat Mode, Otto™ in Reasoning Mode internally processes your instructions more extensively – evaluating evidence, checking consistency, and synthesizing facts into a comprehensive response.

This extra “invisible reasoning” enables stronger legal analysis but may also require more context up front and can take longer to produce results.

Think of Reasoning Mode like briefing a new attorney at your firm – the more context you supply, the stronger the analysis.

Chat Mode vs. Reasoning Mode: Key Differences

When to Use Which Mode

Chat Mode

• Simple Q&A: “What are the rejections against my claims?”

• Fast iteration: “Draft a short paragraph,” “Revise for tone,” “Provide a bullet list.”

• Ongoing conversation: stepping through small tasks or clarifications.

Reasoning Mode

• Deep case analysis: “Review this office action and identify ways to overcome the rejections, including claim amendments.”

• Strategy building: “Draft a detailed litigation roadmap, including recommended motions.”

• Cross-checking multiple documents: “Identify contradictions between the rejections and the claims that we have submitted.”

Bottom Line

• If you want quick, iterative dialogue, go with Chat Mode.

• If you need thorough, step-by-step legal reasoning or multi-step tasks over large sets of data, Reasoning Mode is your best bet—just be ready for longer wait times

Prompt Guidelines for Reasoning Mode

To leverage Otto™’s new Reasoning Mode, you must learn to craft effect prompts. Reasoning Mode enable Otto™ to produce robust legal analyses by “thinking internally” before returning a final answer. You should include each of the following in your prompts:

1. Goal – the specific task you want accomplished

2. Return Format – how you want Otto™ to structure its final response

3. Warnings – caveats, limitations, constraints

4. Context Dump – all the background details, case, info, and instructions you want Otto™ to use.

5. (Optional) Intro – a short summary introducing and tying it all together
