OpenAI API Patterns for GTM

When to use OpenAI

OpenAI excels at: text embeddings for similarity search (finding similar leads/content), structured classification (routing leads, categorizing objections), and fast content generation.

Key patterns

1. Lead similarity scoring: Embed your best customers' descriptions, then embed new leads. Cosine similarity identifies lookalikes.
2. Email classification: Classify inbound replies as positive/negative/neutral/out-of-office using GPT-4o-mini (fast, cheap).
3. Content ideation: Generate content topic ideas based on your best-performing posts and ICP pain points.
4. Data normalization: Clean and standardize CRM data (company names, titles, industries) using structured outputs.

Setup

• API key from platform.openai.com
• Use gpt-4o-mini for classification and simple generation
• Use text-embedding-3-small for embeddings
• Always use structured outputs (JSON mode) for data processing tasks
