OpenAI GPT integration that survives traffic spikes.
Function calling, JSON mode, structured output, vision, prompt caching, retry/fallback chains. The pieces that turn a GPT demo into a production feature.
What's included
Production-grade OpenAI GPT integration that ships, not theater.
- GPT-4o, o1, o3 tier routing
- Function calling with Zod/Pydantic validation
- JSON mode + structured output schemas
- Vision: screenshots, PDFs, images
- Prompt caching for cost reduction
- Retries, fallbacks, rate-limit handling
What you walk away with
Deliverables you keep — code, infrastructure, and the runbook.
- Production OpenAI integration
- Eval suite + monitoring
- Cost dashboard
- Provider abstraction for multi-vendor support
Frequently asked
How do you handle OpenAI rate limits and outages?+
Exponential backoff with jitter, request budgets per user, and fallback chains (GPT-4o → GPT-4 → Claude). Your product stays up when OpenAI has an incident.
When should I use o1 / o3 reasoning models?+
For tasks where the model genuinely needs to think — math, complex code, multi-step planning. They're slower and pricier; I use them when eval shows quality jump justifies cost.
Vision models — practical use cases you've shipped?+
OCR + structured extraction (NameGood does this with business cards). Document processing. UI bug-detection. Product photo analysis. Better than dedicated OCR for most messy real-world images.
