| 4 | * OpenAI Engine implementation. |
| 5 | * |
| 6 | * This engine supports both the standard Chat Completions API and the new Responses API. |
| 7 | * The Responses API is used automatically for models that support it (models with the 'responses' tag). |
| 8 | * |
| 9 | * Key differences when using the Responses API: |
| 10 | * - Function calls and results use specific message types instead of role-based messages |
| 11 | * - MCP (Model Context Protocol) tools are executed remotely by OpenAI |
| 12 | * - Different streaming event structure |
| 13 | * |
| 14 | * @see https://platform.openai.com/docs/api-reference/responses |
