What is the maximum length or complexity of a question or prompt you can give to DeepResearch?

DeepResearch doesn’t enforce a strict maximum length for prompts, but practical limits exist based on how the system processes input. The platform is designed to handle detailed technical questions, including code snippets, data structures, or multi-part queries, but overly long or unstructured prompts may reduce response quality. For example, while you could theoretically submit a prompt with thousands of words, the model might prioritize earlier sections and lose focus on critical details buried in later paragraphs. A good rule of thumb is to keep prompts under 400-500 words for optimal results, roughly equivalent to a few paragraphs of code plus explanatory text.

Complexity is managed through clear structuring. DeepResearch excels at parsing technical content like error logs, API documentation excerpts, or algorithm design challenges, but it requires logical flow. For instance, a prompt asking to “debug this Python function that throws a null pointer exception when processing JSON input” will work better than a meandering description of a problem without code or specific error messages. Developers should break complex tasks into numbered sub-questions (e.g., “1. Why does this loop crash? 2. How to optimize the SQL query below?”) and use code fences (```) to separate technical details from explanatory text. This helps the system distinguish between problem statements and supporting context.

For maximum effectiveness, balance depth with precision. Include necessary technical specifics—like language versions, library dependencies, or sample inputs/outputs—while avoiding redundant information. For example:

// Include relevant code snippets 
def failing_function(data: list) -> None: 
 for item in data: 
 print(item.trim()) # Fails when item is None 

A prompt combining this code with “Why does this Python 3.8 function crash on empty lists?” works better than generic descriptions. If your question requires analyzing multiple components (e.g., a distributed system with frontend/backend issues), split it into separate prompts or explicitly partition sections using headers like “Frontend Error:” and "Database Layer:". Test your prompt by asking: “Could a colleague understand this without extra context?” If yes, DeepResearch likely will too.
