Response Example

The expected response structure for the AI21 model might look like this:

{
  "id": "chatcmpl-12345example12345",
  "object": "chat.completion",
  "created": 1729535643,
  "provider": "openrouter",
  "model": "jamba-instruct",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy. Here's how it works:\n\n1. **Light Absorption**: Plants capture light energy using a pigment called chlorophyll, which is found in chloroplasts.\n\n2. **Water and Carbon Dioxide**: They absorb water through their roots and carbon dioxide from the air.\n\n3. **Glucose Production**: The light energy is used to convert water and carbon dioxide into glucose (a sugar) and oxygen. The equation is:\n   \n   6CO2 + 6H2O + light energy → C6H12O6 + 6O2\n\nThis process provides energy for the plant and releases oxygen into the atmosphere."
      },
      "logprobs": null,
