Ishi Meets GPT-4o

OpenAI's models remain the industry standard for many workflows. Here's how to integrate GPT-4o, o3, and the full OpenAI suite with Ishi.

Why OpenAI with Ishi?

OpenAI offers:

• GPT-4o — Fast, multimodal, great for everyday tasks
• o3 — Advanced reasoning for complex problems
• Whisper — Speech-to-text (built into Ishi!)
• Massive ecosystem — Widest third-party support

Quick Setup

API Key Configuration

1. Get your key from platform.openai.com
2. Configure in Ishi:

{
  "provider": "openai",
  "model": "gpt-4o"
}

Available Models

| Model | Speed | Context | Best For | |-------|-------|---------|----------| | gpt-4o | Fast | 128K | General tasks | | gpt-4o-mini | Fastest | 128K | Quick operations | | o3 | Slower | 200K | Complex reasoning | | o4-mini | Medium | 200K | Balanced reasoning |

Practical Example: PDF Data Extraction

Here's GPT-4o helping extract data from invoices:

You: "Extract vendor name, amount, and date from all PDFs in my Invoices folder"

GPT-4o + Ishi:
1. Scans 47 PDF files
2. Extracts structured data via vision
3. Creates invoices.csv with columns: Vendor, Amount, Date, Filename
4. Ghost preview shows the CSV before writing

GPT-4o can analyze images and screenshots:

• Read handwritten notes
• Extract text from photos
• Analyze charts and diagrams
• Process scanned documents

Cost Optimization

Ishi helps you manage API costs:

• Local caching — Don't re-process unchanged files
• Smart batching — Combine related requests
• Model selection — Use gpt-4o-mini for simple tasks

BYOK: Bring Your Own Key

Unlike subscription-based tools, Ishi uses your API key directly:

• Pay only for what you use
• No markup on API costs
• Full usage visibility
