Mistral 7B Instruct - "cannot parse response" after one or two response

[Janaka-Steph]

See https://github.com/premAI-io/prem-app/issues/514

To replicate the regression bug (and maybe is time to have an end-to-end test to run automatically)

• Run Mistral 7B Instruct locally
• Assuming is running on http://localhost:8447

1. First HTTP request (usually successful)

curl --location 'http://localhost:8447/v1/chat/completions' \
--header 'Content-Type: application/json' \
--data '{
    "model": "mistral-7b-instruct-v0.1.Q5_0.gguf",
    "messages": [
        {
            "role": "user",
            "content": "explain Bitcoin like I am 5"
        }
    ],
    "stream": true,
    "temperature": 0.2,
    "max_tokens": 256,
    "top_p": 0.95,
    "frequency_penalty": 0,
    "n": 1,
    "presence_penalty": 0
}'

2. Second call with anything, it will return stop early on

curl --location 'http://localhost:8447/v1/chat/completions' \
--header 'Content-Type: application/json' \
--data '{
    "model": "mistral-7b-instruct-v0.1.Q5_0.gguf",
    "messages": [
        {
            "role": "user",
            "content": "do it with emoji"
        }
    ],
    "stream": true,
    "temperature": 0.2,
    "max_tokens": 256,
    "top_p": 0.95,
    "frequency_penalty": 0,
    "n": 1,
    "presence_penalty": 0
}'

Interesting: I assume you using in-process python to run it right? so it may be the packaging (ie. pyinstaller?) as the reason for the divergence?

[biswaroop1547]

tried again with cht-llama-cpp-mistral-1-aarch64-apple-darwin, but got similar response 🤔 can you try on a clean download maybe?
