🔑 1. OpenAI API Key Usage

✅ 5 Key Points – Using os.getenv("OPEN_AI_API_KEY") for API Key:

1. os.getenv() Reads Env Vars – Fetches OPEN_AI_API_KEY from environment variables.
2. Must Export It 🔐 – Before running:

   export OPEN_AI_API_KEY="your_api_key"
   
   
   
   ## 🎙️ 2. Whisper AI – Speech to Text  
   

✅ 5 Key Points – Using Whisper AI with ChatGPT/OpenAI:

1. What is Whisper? 🎙️ – OpenAI’s automatic speech recognition (ASR) model for converting audio to text.
2. Usage in Code 💻:

   import openai
   
   openai.api_key = "your_api_key"
   
   audio_file = open("your_audio.mp3", "rb")
   transcript = openai.Audio.transcribe("whisper-1", audio_file)
   
   print(transcript["text"])

📦 3. Why Install multipart?

✅ 2 Key Points – pip install multipart:

1. Purpose – Parses multipart/form-data for handling file uploads in FastAPI and similar frameworks.
2. Example:

   from fastapi import FastAPI, File, UploadFile
   
   app = FastAPI()
   
   @app.post("/upload/")
   async def upload(file: UploadFile = File(...)):
       return {"filename": file.filename}
   

🆕 4. Using Latest OpenAI Version

✅ 5 Key Points – Updating to Latest OpenAI SDK:

1. API Key Change 🔑 – Old: openai.apikey ❌ → New: OpenAI(api_key=...) ✅
2. File Handling 📂 – Files are temporarily saved before being sent to the API.
3. Method Update 🛠️ – Old: transcribe() ❌ → New: client.audio.transcriptions.create(...) ✅
4. FastAPI Integration ⚡ – UploadFile = File(...) ensures proper multipart/form-data handling.
5. Future-Proofing 🚀 – v1+ syntax prevents deprecation issues and keeps code up-to-date.
