Model Selection

Choose between different AI models powering Viete to balance speed, cost, and capability based on your needs. Different models excel at different tasks, giving you control over performance and efficiency.

Available Models

Viete offers multiple AI model options, each optimized for different use cases:

Claude Sonnet (Default)

RECOMMENDED

The optimal balance of intelligence, speed, and cost for most Excel modeling tasks.

Best For:

  • • Standard Excel model generation
  • • Most automation and workflows
  • • Typical business analysis
  • • General-purpose use

Characteristics:

  • • Fast response times
  • • Cost-effective
  • • High quality outputs
  • • Reliable and consistent

Claude Opus

The most capable model for complex, nuanced Excel modeling requiring deep reasoning.

Best For:

  • • Complex financial models
  • • Advanced formula logic
  • • Ambiguous or nuanced requirements
  • • Critical client deliverables

Characteristics:

  • • Highest intelligence
  • • Best reasoning capability
  • • Slower than Sonnet
  • • Higher cost

Claude Haiku

The fastest, most cost-effective model for simpler Excel tasks and high-volume processing.

Best For:

  • • Simple data formatting
  • • High-volume batch processing
  • • Straightforward conversions
  • • Cost-sensitive applications

Characteristics:

  • • Fastest response
  • • Most cost-effective
  • • Good for simple tasks
  • • Lower capability vs Sonnet/Opus

How to Choose

Select models based on task complexity and requirements:

Use Haiku When:

  • • Converting CSV to formatted Excel tables
  • • Simple data restructuring
  • • Processing hundreds of similar files in parallel
  • • Basic automation with clear data patterns
  • • Cost is a primary concern and tasks are straightforward

Use Sonnet When:

  • • Most business analysis and reporting
  • • Standard financial models and dashboards
  • • Typical automation and workflow scenarios
  • • You need good results without premium cost
  • • General-purpose Excel modeling (90% of use cases)

Use Opus When:

  • • Complex financial modeling with advanced formulas
  • • Ambiguous requirements needing interpretation
  • • Critical client deliverables requiring perfection
  • • Novel or unusual Excel modeling challenges
  • • Quality is paramount regardless of cost/speed

Model Selection in Practice

You can specify models in different contexts:

Ad-Hoc Generation

Choose model when creating one-off Excel files. Start with Sonnet, upgrade to Opus if results need refinement.

Automations

Set default model for automation. Haiku for simple data pulls, Sonnet for standard reporting, Opus for complex analysis.

Workflows

Configure per-workflow model selection. Use Haiku for high-volume batch processing, Sonnet/Opus for critical transformations.

Cost vs. Quality Trade-off

Relative Comparison

Haiku
Speed: ⚡⚡⚡⚡⚡Cost: $Quality: ⭐⭐⭐
Sonnet
Speed: ⚡⚡⚡⚡Cost: $$Quality: ⭐⭐⭐⭐
Opus
Speed: ⚡⚡⚡Cost: $$$Quality: ⭐⭐⭐⭐⭐
Tip
When in doubt, start with Sonnet. It handles 90% of Excel modeling tasks excellently. Only move to Opus if you encounter complexity Sonnet struggles with, or to Haiku if you're doing high-volume simple processing.
Note
Model selection can be changed mid-session. If Sonnet produces good results but you want to refine further, switch to Opus for the refinement iterations.
