GPT: how to connect to model

how do i connect an agent to a model that is a small experimental model i created?
ChatGPT said:

To connect an agent to a small experimental language model you've created, you'll need to establish an interface between the two. Here's a high-level breakdown of the steps, followed by more detailed options depending on your setup.


πŸ”§ Key Concepts

  • Agent: A system that sends prompts/queries and handles responses (e.g., a chatbot, script, or tool).

  • Model: Your experimental language model, likely a trained model (e.g., a small transformer or RNN).

  • Interface: The way the agent communicates with the model (API, function call, socket, etc.).


βœ… Options to Connect an Agent to a Model

1. Function-based Interface (Python)

If your model is just a Python object or function:

python
CopyEdit
# Define your model as a callable function def my_model(prompt): # Your generation logic here return "This is a response to: " + prompt # Your agent uses this function def agent(): user_input = input("You: ") response = my_model(user_input) print("Agent:", response)

agent()

Use this if your model runs in the same Python environment.


2. Web API Interface

Wrap your model in a small web API using something like FastAPI or Flask:

python
CopyEdit
from fastapi import FastAPI, Request import uvicorn

app = FastAPI()

@app.post("/generate") async def generate(request: Request): data = await request.json() prompt = data["prompt"] # Call your model here result = your_model(prompt) return {"response": result} if name == "main": uvicorn.run(app, host="0.0.0.0", port=8000)

Your agent can then send HTTP POST requests to http://localhost:8000/generate.


3. Command-line / Process Communication

If your model runs in a separate process (e.g., it's a compiled binary or separate script), use subprocess:

python
CopyEdit
import subprocess def call_model(prompt): result = subprocess.run(["python", "my_model.py"], input=prompt.encode(), capture_output=True) return result.stdout.decode() print(call_model("What is AI?"))

4. Socket-based Communication

For more robust setups or real-time systems, use sockets (TCP/UDP). Useful when model and agent run on different machines.


πŸ”„ Bonus: Using LangChain or Autogen

If you’re building agents with frameworks like LangChain, you can register your model as a custom LLM wrapper class.

python
CopyEdit
from langchain.llms.base import LLM class MyCustomModel(LLM): def _call(self, prompt, stop=None): return your_model(prompt) # Then use it in LangChain tools or chains

πŸ“¦ Summary

Method | When to Use -- | -- Function Call | Same process, simplest form Web API (FastAPI) | Reusable or remote access Subprocess | Model is external script or binary Sockets | Custom setups, distributed agents LangChain Wrapper | Using agent frameworks like LangChain

If you tell me more about:

  • What framework or model you're using (PyTorch? Hugging Face? Something custom?)

  • What kind of agent you're building (chatbot? CLI? web?)

  • Whether you want to run it locally or expose it as a service

…I can give a more tailored answer or code snippet.
