What GPT integration actually requires in 2026
2026 OpenAI default: Vercel AI SDK or OpenAI Node/Python SDK, structured outputs (JSON mode + Zod schemas), function calling for tool use, Responses API for stateful conversations, and Batch API for cost-savings on non-realtime workloads. OpenAI integrations look easy in a demo, hard in production. Senior engineers handle rate limits, retry-with-backoff, content-moderation pre-checks, prompt-injection mitigation, and cost-per-tenant accounting. None of these are in the OpenAI quickstart.
