OpenAI Assistants API Tutorial

OpenAI Dev Day showcased groundbreaking AI services, including the Assistants API, GPTs, the GPTs App Store, and GPT-4 Turbo. This tutorial explores the Assistants API, detailing its capabilities, diverse applications, and implementation using Python.

The Assistants API (currently in beta) leverages OpenAI models (GPT-4, GPT-4 Turbo, GPT-3.5, GPT-3, DALL-E, TTS, Whisper, Embeddings, Moderation) and tools (Code interpreter, Knowledge Retrieval, and custom tools via Function Calling).

Assistant implementation involves five steps:

1. Create and describe the Assistant: Define its purpose, instructions, model, and tools.
2. Initiate a Thread: Start a conversation.
3. Add Messages: Input user requests (text, files, images).
4. Trigger the Assistant: Initiate processing.
5. Receive the Response: Obtain the Assistant's output.

Industry Applications:

• Development Support: Code translation, language learning assistance.
• Enterprise Knowledge Management: Centralized knowledge repository for internal documents.
• Customer Support Automation: Automated responses to common queries.
• Data Analysis: Natural language data manipulation and report generation.
• IT Operation Automation: Automation of routine IT tasks.

Hands-on: Knowledge Retrieval from PDFs:

This section guides you through building an assistant that retrieves information from PDFs. A complete notebook is available on DataLab.

Setup:

Requires Python, the OpenAI package, and the OS package. Obtain your OpenAI API key (see image below for steps) and set it as an environment variable:

import os
OPENAI_API_KEY = "<your_private_key>"
os.environ["OPENAI_API_KEY"] = OPENAI_API_KEY</your_private_key>

Code Example (Excerpts):

File Upload:

def upload_file(file_path):
    file_to_upload = client.files.create(file=open(file_path, "rb"), purpose='assistants')
    return file_to_upload

transformer_paper_path = "./data/transformer_paper.pdf"
file_to_upload = upload_file(transformer_paper_path)

Assistant Creation:

def create_assistant(assistant_name, instructions, uploaded_file, model="gpt-4-1106-preview"):
    my_assistant = client.beta.assistants.create(name=assistant_name, instructions=instructions, model=model, tools=[{"type": "retrieval"}], file_ids=[uploaded_file.id])
    return my_assistant

# ... (rest of the code)

Best Practices:

• Clearly define objectives.
• Use high-quality, relevant data.
• Prioritize user privacy.
• Test and iterate.
• Provide clear documentation.

Conclusion:

The Assistants API offers powerful capabilities across diverse industries. This tutorial provided a practical introduction to its functionality and implementation. For further exploration, consider our Comprehensive Guide to the DALL-E 3 API or our Working with the OpenAI API course.
