- All download data will be downloaded at
~/catai
folder by default. - The download is multi-threaded, so it may use a lot of bandwidth, but it will download faster!
There is also a simple API that you can use to ask the model questions.
const response = await fetch('http://127.0.0.1:3000/api/chat/prompt', {
method: 'POST',
body: JSON.stringify({
prompt: 'Write me 100 words story'
}),
headers: {
'Content-Type': 'application/json'
}
});
const data = await response.text();
For more information, please read the API guide
You can also use the development API to interact with the model.
import {createChat, downloadModel, initCatAILlama, LlamaJsonSchemaGrammar} from "catai";
// skip downloading the model if you already have it
await downloadModel("meta-llama-3-8b-q4_k_m");
const llama = await initCatAILlama();
const chat = await createChat({
model: "meta-llama-3-8b-q4_k_m"
});
const fullResponse = await chat.prompt("Give me array of random numbers (10 numbers)", {
grammar: new LlamaJsonSchemaGrammar(llama, {
type: "array",
items: {
type: "number",
minimum: 0,
maximum: 100
},
}),
topP: 0.8,
temperature: 0.8,
});
console.log(fullResponse); // [10, 2, 3, 4, 6, 9, 8, 1, 7, 5]
(For the full list of model, run catai models
)
You can use the model with node-llama-cpp@beta
CatAI enables you to easily manage the models and chat with them.
import {downloadModel, getModelPath, initCatAILlama, LlamaChatSession} from 'catai';
// download the model, skip if you already have the model
await downloadModel(
"https://huggingface.co/QuantFactory/Meta-Llama-3-8B-Instruct-GGUF/resolve/main/Meta-Llama-3-8B-Instruct.Q2_K.gguf?download=true",
"llama3"
);
// get the model path with catai
const modelPath = getModelPath("llama3");
const llama = await initCatAILlama();
const model = await llama.loadModel({
modelPath
});
const context = await model.createContext();
const session = new LlamaChatSession({
contextSequence: context.getSequence()
});
const a1 = await session.prompt("Hi there, how are you?");
console.log("AI: " + a1);
