Use cases & scenarios

Compromises

  • Data leakage or unintended disclosure of sensitive inputs
  • Vendor lock-in due to proprietary APIs and formats
  • Compliance and data protection issues with personal data
  • Version control prompt templates and example sets
  • Implement fallback strategies for erroneous or unexpected responses
  • Restrict cost and rate limits per environment

I/O & resources

  • API key with appropriate permissions
  • Input prompt or user data
  • Configuration parameters (model, temperature, max tokens)
  • Generated text, image or embedding vector
  • Usage metrics and token consumption
  • Error and status responses

Description

The OpenAI API is a hosted cloud service providing access to advanced AI models for text, image and embedding tasks. Developers use REST endpoints and official SDKs to send requests, configure models, and integrate outputs into applications. Common uses include prototyping, automation, and generative assistance features.

✔

  • Fast access to powerful models without owning infrastructure
  • Rapid prototyping and iteration
  • Wide model range for diverse tasks

✖

  • Ongoing operational costs due to pay-per-use pricing
  • Limited control over model internals and updates
  • Latency and availability depend on the service provider

  • Latency (p50/p95)

    Measurement of round-trip time for API requests, critical for UX.

  • Tokens per request

    Number of tokens processed influences cost and performance.

  • Error rate (4xx/5xx)

    Rate of erroneous responses or system failures.

Customer support chatbot (pilot)

Pilot project classifying customer queries and delivering standard replies.

Search index with semantic embeddings

Embedding integration to improve relevance in product search.

Automated report summarization

System summarizes incoming reports and generates executive summaries.

1

Set up API access, store keys securely and verify permissions.

2

Install SDK, implement a simple request and add response validation.

3

Configure monitoring, rate-limit handling and cost alerts.

⚠️ Technical debt & bottlenecks

  • Tight coupling to specific API endpoints without abstraction
  • No mechanisms for cost monitoring and budget control
  • Missing tests for model output stability during updates
Network latencyAPI rate limitsCost control
  • Using the API to store personal data without legal basis
  • Automated decisions without human oversight
  • Excessive parallel requests that exceed rate limits
  • Underestimating token costs for large prompts
  • Missing monitoring alerts for error states
  • Ignoring usage policies and content guidelines
