Key Features & Support:
- Massive Context: Supports a context window of up to 500,000 tokens, along with text and image inputs.
- Adjustable Reasoning: Offers low, medium, and high reasoning effort levels to adapt to task complexity.
- Performance: Internal tests show strong results in terminal-based coding tasks within VS Code and Copilot CLI, particularly excelling at parallel tool dispatch and direct action—making it ideal for exploration and time-sensitive debugging.
- Availability: Supported across major IDEs including VS Code, Visual Studio, JetBrains, Xcode, and Eclipse.
- Billing: Billed at provider list pricing under usage-based billing. Available to Copilot Pro, Pro+, Max, Business, and Enterprise SKUs (admins must manually enable the policy for Business/Enterprise plans).
