Rename OpenAIProcessorConversationConfig DB model to more apt AiModelApi (#998) 
* Rename OpenAIProcessorConversationConfig to more apt AiModelAPI

The DB model name had drifted from what it is being used for,
a general chat api provider that supports other chat api providers like
anthropic and google chat models apart from openai based chat models.

This change renames the DB model and updates the docs to remove this
confusion.

Using Ai Model Api we catch most use-cases including chat, stt, image generation etc.

LiteLLM

:::info This is only helpful for self-hosted users. If you're using Khoj Cloud, you're limited to our first-party models. :::

:::info Khoj natively supports local LLMs available on HuggingFace in GGUF format. Using an OpenAI API proxy with Khoj maybe useful for ease of setup, trying new models or using commercial LLMs via API. :::

LiteLLM exposes an OpenAI compatible API that proxies requests to other LLM API services. This provides a standardized API to interact with both open-source and commercial LLMs.

Using LiteLLM with Khoj makes it possible to turn any LLM behind an API into your personal AI agent.

Setup

  1. Install LiteLLM 
    pip install litellm[proxy]
  2. Start LiteLLM and use Mistral tiny via Mistral API 
    export MISTRAL_API_KEY=<MISTRAL_API_KEY>
litellm --model mistral/mistral-tiny --drop_params
  3. Create a new API Model API on your Khoj admin panel
    • Name: proxy-name
    • Api Key: any string
    • Api Base Url: URL of your Openai Proxy API
  4. Create a new Chat Model Option on your Khoj admin panel.
    • Name: llama3.1 (replace with the name of your local model)
    • Model Type: Openai
    • Openai Config: <the proxy config you created in step 3>
    • Max prompt size: 20000 (replace with the max prompt size of your model)
    • Tokenizer: Do not set for OpenAI, Mistral, Llama3 based models
  5. Go to your config and select the model you just created in the chat model dropdown.
