BexAI offers different Claude AI models developed by Anthropic. These models provide different levels of processing speed, reasoning capability, and analytical depth.

Selecting a model allows users to match the AI's capabilities to the complexity of their task. The model determines how BexAI processes a request; Chat or Agent determines how the user interacts with BexAI.

AI model

Primary strength

Recommended BexAI use

Claude Haiku 5

Speed and efficiency

Quick compliance questions, definitions, summarizing documents, and routine information requests

Claude Sonnet 5

Balanced speed and reasoning

Trade compliance research, HTS and ECCN classification assistance, regulatory explanations, and document analysis

Claude Opus 5

Advanced reasoning and complex analysis

Claude Haiku 5 — Fast, Everyday Assistance

Haiku is designed for speed and efficient processing of straightforward requests. It is useful for obtaining quick answers, summarizing information, and handling routine questions that do not require extensive analysis.

Example: “What does EAR99 mean?”

Claude Sonnet 5 — Balanced Analysis and Performance

Sonnet provides a balance between response speed and analytical capability, making it suitable for many everyday trade compliance activities. It can assist with interpreting regulatory requirements, reviewing product information, and explaining classification considerations.

Example: “Explain the differences between HTS classification and ECCN classification for electronic components.”

Claude Opus 5 — Advanced Research and Reasoning

Opus is designed for complex tasks requiring more extensive reasoning, detailed analysis, and consideration of multiple factors. It is particularly useful when evaluating complicated regulatory scenarios or working through multi-step compliance questions.

Example: “Analyze the potential US import duty considerations for a product manufactured in multiple countries, including applicable trade remedies and country-of-origin requirements.”

Choosing the Appropriate BexAI Model

For most routine questions and research, Sonnet provides a practical balance of speed and analytical capability. Haiku is appropriate for simpler requests where quick responses are preferred, while Opus is better suited for complex research requiring additional depth.

Important: AI-generated responses are intended to assist with research and decision-making. Users should independently verify classifications, regulatory interpretations, license requirements, and other compliance-sensitive information against authoritative sources before taking action.
