Available AI models and capabilities

This guide lists all AI models and agent capabilities avaiable for your AI agent. You can customize your agent’s capabilities by choosing the model that fits your goals.

Standard Users

Standard users have access to the Optimal Choice agent capability which comes with a GPT-4.1 model.

Optimal Choice delivers balanced performance for accuracy, speed, and intelligence, ideal for most general-purpose use cases.

Premium Users

In addition to Optimal Choice, Premium users can switch between three additional capabilities:

  • Fastest Responses – Uses GPT-4o mini and pptimized for shorter, faster replies and high responsiveness.
  • Highest Relevance – Uses GPT-4.1 and optimizes how the AI agent selects and uses contextual information from your data.
  • Complex Reasoning – Uses GPT-5.1 Optimal for deeper reasoning, structured problem-solving, and more analytical or technical interactions.

Enterprise Users

Enterprise users can fully customize which AI model powers each agent. This includes access to the most advanced GPT and Claude models optimized for different use cases and reasoning needs.

  • Fastest Responses: GPT-4o mini, GPT-4.1 mini and Claude 3.5 Haiku.
  • Optimal Choice: GPT-4.1, GPT-4o, GPT-5, GPT-5.1 Optimal, GPT-5.1 Smart, GPT-4.1 mini, GPT-4o mini, Claude 4.5 Opus, Claude 4.5 Sonnet, Claude 4 Sonnet and Claude 3.5 Haiku.
