Update Answer Model

3 stepsAgent View (JSON)

Overview

Nia's Answer Model setting determines which large language model powers your search and analysis responses. Claude Opus 4.7 is Nia's most advanced reasoning model, designed to handle complex, multi-step analysis and provide more nuanced answers compared to standard models. Upgrading to this model enhances the quality of cited answers you receive when searching across indexed sources. This change applies globally to all Answer API calls and chat sessions under your workspace account and requires an active Pro plan to access.

Before you begin

  • An active Nia account with access to app.trynia.ai (you must be logged in)
  • An active Pro plan subscription (Claude Opus 4.7 is not available on free or starter plans)
  • Access to workspace settings (typically available to workspace admins or account owners)

Step by step

1
ClickAnswer Model

Navigate to the Answer Model configuration page by clicking the 'Answer Model' link in your workspace settings. This opens the model selection interface where you can review all available AI models and their capabilities.

Tip. The Answer Model link is typically found in the left sidebar under Settings or in the main workspace configuration menu. If you can't locate it, use your browser's search function (Ctrl+F or Cmd+F) to find 'Answer Model' on the page.

Select Claude Opus 4.7 as your Answer Model by clicking the radio button next to its name. This model is described as 'Most capable model for deep reasoning and analysis' and is the premium option requiring a Pro plan.

Tip. Hover over the model description to see additional details about its capabilities and when to use it. Claude Opus 4.7 is best for complex reasoning tasks, technical analysis, and multi-step problem solving.
Warning. Ensure your workspace has an active Pro plan before selecting this model. Selecting it without Pro access may result in an error at save time or unexpected billing.
Step 2
