How Do I: Choose the Right AI Assistant for AL Development?

GitHub Copilot's usage-based billing with model multipliers, starting June 1, prompts a task-based choice of AI tool for AL work. Copilot in VS Code suits code generation that needs workspace context, while Claude.ai or the desktop app gives frontier reasoning models without multipliers for architecture, review and error analysis. The author later noted that this post conflated two billing models and pointed readers to a follow-up correction.

Key points

  • GitHub Copilot has structural advantage in VS Code due to editor integration and access to workspace symbols and AL objects
  • Claude.ai and Claude desktop app provide frontier reasoning models without Copilot multipliers, making them cheaper for complex analysis and architecture work
  • Pricing multipliers vary significantly by model: Haiku at 0.33x, Sonnet at 1x, and Opus at 27x under Copilot’s usage-based billing
  • Different AI tools suit different workflows: Copilot for inline completions, Claude for reasoning, and Copilot Agent for multi-file refactoring
  • The June 1 pricing change makes the cost of frontier models inside Copilot visible and may justify moving reasoning work to separate tools
