Node.js OpenAI GPT API Text Summarization Direct for One Provider Unified for Many

Description and use

A Node.js team implements automated ticket summarization with tenant attribution and cost visibility, choosing between direct OpenAI, Bedrock, Vertex AI, or a unified gateway.

Problem

How to integrate OpenAI GPT API for text summarization in a Node.js team while ensuring tenant attribution and cost visibility across multiple backends.

Outcome

The team can now generate concise, tenant‑attributed summaries for support tickets, with clear cost attribution and the ability to scale across multiple providers.

Workflow

• 1. Define a small labeled ticket set (40 tickets, 4 tenants, 2 languages, 3 classes).
• 2. Create a prompt that includes tenant ID and ticket text.
• 3. Call the chat‑completion endpoint with low temperature and max_tokens=120.
• 4. Retry on 429 with exponential backoff up to 4 attempts.
• 5. Capture request ID, latency, cost metadata, and tenant ID for accounting.
• 6. In production, split or truncate long tickets before the call.
• 7. Choose integration path: direct OpenAI, Bedrock, Vertex AI, or unified gateway based on provider ownership and billing needs.

Evidence

Use a small labeled ticket set before choosing an integration. I would start with 40 tickets across four tenants, two languages, and three classes: billing, access, and suspected outage.

Source

The chosen experiment sends a stable tenant identifier alongside the request in the application trace, records input and output token counts, and compares the result with a fixed rubric.

I would pick direct OpenAI when the support system has one provider, one billing owner, and a small number of tenants.
