ChatGPT Plugin Development

Extend ChatGPT with secure, real-time integrations.

Overview

ChatGPT plugins extend base LLM capabilities through secure, sandboxed API calls—enabling real-time data access, action execution, and two-way integrations with SaaS and enterprise systems.

State-of-the-Art Methods and Architectures

OpenAPI Spec

Defines plugin endpoints, input/output schemas, and authentication flows.

Plugin Manifest

JSON file registering name, description, auth type (OAuth, API key), and API routes.

Sandboxed Execution

LLM issues HTTPS requests within hardened environments to prevent injection attacks.

Market Landscape & Forecasts

Stock, Weather

Live Data Retrieval

Book, Buy, Invoice

Transactional Actions

Salesforce, Jira

Enterprise Integrations

Implementation Guide

Design API Contract

Define endpoint routes, parameters, and responses using OpenAPI.

Implement Backend

Build RESTful services in Node.js / Python / Go with robust authentication.

Create Manifest & UI Metadata

Include logo, entry points, help docs.

Test & Deploy

Use the OpenAI plugin CLI to simulate conversations and validate flows.

Technical Deep Dive

Data Preparation

Collect domain-specific text (e.g., medical records, legal documents). Clean and format data into JSONL.

Adapter Insertion

Insert LoRA/QLoRA adapters into the base model.

Training

Run training with domain data, using a learning rate schedule and early stopping. Monitor loss and validation metrics.

Evaluation

Use ROUGE, accuracy, or custom metrics. Compare outputs to base model.

Sample Code

from transformers import AutoModelForCausalLM, TrainingArguments, Trainer model = AutoModelForCausalLM.from_pretrained('llama-7b') # Insert LoRA adapters... # Prepare data... trainer = Trainer(model=model, args=TrainingArguments(...), train_dataset=...) trainer.train()

Why Fine-Tuning?

No Plugin

- LLM can't access real-time data - No external actions - Limited to static knowledge

With Plugin

- Real-time data access - Can trigger actions - Integrates with SaaS/enterprise systems
