Ollama Support

[k2an]

I love your project, I want to use it with local ollama+llava and i tried many way including asking chat gpt. I am on Windows 11, i tried docker and no go. changed api address from settings in frontend also

api key as "ollama" and 
Api Url as http://localhost:11434/v1/ 

and i tested my local ollama+llava answering and running with postman.

changed frontend\src\lib\models.ts

// Keep in sync with backend (llm.py)
// Order here matches dropdown order
export enum CodeGenerationModel {
  GPT_4O_2024_05_13 = "llava", --> HERE
  GPT_4_TURBO_2024_04_09 = "gpt-4-turbo-2024-04-09",
  GPT_4_VISION = "gpt_4_vision",
  CLAUDE_3_SONNET = "claude_3_sonnet",
}

// Will generate a static error if a model in the enum above is not in the descriptions
export const CODE_GENERATION_MODEL_DESCRIPTIONS: {
  [key in CodeGenerationModel]: { name: string; inBeta: boolean };
} = {
  "llava": { name: "LLava", inBeta: false }, --> and here
  "gpt-4-turbo-2024-04-09": { name: "GPT-4 Turbo (Apr 2024)", inBeta: false },
  gpt_4_vision: { name: "GPT-4 Vision (Nov 2023)", inBeta: false },
  claude_3_sonnet: { name: "Claude 3 Sonnet", inBeta: false },
};

also backend\llm.py

Actual model versions that are passed to the LLMs and stored in our logs

class Llm(Enum):
    GPT_4_VISION = "gpt-4-vision-preview"
    GPT_4_TURBO_2024_04_09 = "gpt-4-turbo-2024-04-09"
    GPT_4O_2024_05_13 = "llava"
    CLAUDE_3_SONNET = "claude-3-sonnet-20240229"
    CLAUDE_3_OPUS = "claude-3-opus-20240229"
    CLAUDE_3_HAIKU = "claude-3-haiku-20240307"


 Will throw errors if you send a garbage string
def convert_frontend_str_to_llm(frontend_str: str) -> Llm:
    if frontend_str == "gpt_4_vision":
        return Llm.GPT_4_VISION
    elif frontend_str == "claude_3_sonnet":
        return Llm.CLAUDE_3_SONNET
    elif frontend_str == "llava":
        return Llm.GPT_4O_2024_05_13
    else:
        return Llm(frontend_str)

If can be use on local server it'll be awesome! Thanks for consideration
