# Returning Log probabilities

In some cases you might want to get the log probabilities for each token
generated by our LLM streaming API. By default, our streaming API returns the
generated tokens on by one and the log probabilities are attached to each
token.

## Example

Here is quick example.

    
    
    curl -X POST \   
        -d '{"input": "I have this dream", "stream": true}'  \
        -H "Authorization: bearer YOUR_API_KEY"  \
        -H 'Content-Type: application/json'  \
        'https://api.deepinfra.com/v1/inference/meta-llama/Llama-2-7b-chat-hf'
    data: {"token": {"id": 29892, "text": ",", "logprob": -2.65625, "special": false}, "generated_text": null, "details": null}
    data: {"token": {"id": 988, "text": " where", "logprob": -0.39575195, "special": false}, "generated_text": null, "details": null}
    data: {"token": {"id": 1432, "text": " every", "logprob": -3.15625, "special": false}, "generated_text": null, "details": null}
    data: {"token": {"id": 931, "text": " time", "logprob": -0.1385498, "special": false}, "generated_text": null, "details": null}
    
    
    copy

The `logprob` field is the log probability of the token generated.

Log probabilities are currently not returned for the non-streaming API, or out
OpenAPI compatible API.
