Adding message parameter support for OpenAI models

[Hkllopp]

OpenAI models uses the message parameter for the prompt. ScrapegraphAI also use this parameter to link to the prompt argument on scrapper invocation.
However, sometimes when using openAI models, we need to make multiple prompts to better guide the response (like in this article and this documentation).

Is it possible to replace the standart scrapGraphAI prompt when providing message argument in the graph_config ?

Example :

import os
from scrapegraphai.graphs import SmartScraperGraph

OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")

system_prompt = "Provide output in valid JSON."
user_prompt = "List me all the news article with a brief description for each one."

graph_config = {
    "llm": {
        "api_key": OPENAI_API_KEY,
        "model": "gpt-3.5-turbo",
        "response_format": {"type": "json_object"},
        "seed": 0,
        "temperature": 0,
        "messages": [
            {"role": "system", "content": system_prompt},
            {"role": "user", "content": user_prompt},
        ],
    },
    "verbose": True,
}

smart_scraper_graph = SmartScraperGraph(
    prompt=user_prompt,
    # also accepts a string with the already downloaded HTML code
    source="https://perinim.github.io/projects",
    config=graph_config,
)

# TypeError: openai.resources.chat.completions.Completions.create() got multiple values for keyword argument 'messages'```

ok, it could be an idea but please provide me a use case for the system prompt.
The output is already in the json format

Well, another example is that users that want to use groq with llama3-70b they need to mention the word JSON in the system-prompt message, its mandatory.

Even if the output format is in json?

[ehecatl]

Yes, according to the groq playground, the system message should contain the word JSON El El sáb, 15 de jun de 2024 a la(s) 12:38 a.m., Marco Vinciguerra < ***@***.***> escribió:
