AI Wrapper / LLM App

Ship your AI-powered app with production-grade reliability

Code review and production services for AI wrapper apps, LLM integrations, and ChatGPT-powered applications built with AI coding tools.

AI wrapper apps — products built on top of OpenAI, Anthropic, or other LLM APIs — have unique production challenges. The AI model is a black box that's slow, expensive, and unpredictable. Your app needs to handle variable response times, API failures, cost management, and output quality control in ways that standard web apps don't.

AI Wrapper / LLM App challenges we solve

The most common issues in AI-built ai wrapper / llm app projects.

API cost management

LLM API calls are expensive. A single unoptimized prompt can cost cents per request — which adds up fast with real users. You need token counting, cost tracking, usage limits per user, and prompt optimization to stay profitable.

Response time variability

LLM responses take 1-30 seconds depending on prompt complexity, model load, and output length. Your UI needs streaming responses, loading states, and timeout handling. Users abandon apps that feel slow.

Error handling for AI responses

The AI model might: return an error, time out, return malformed output, refuse to answer, or hallucinate. Each case needs specific handling. AI tools build the happy path but not the many failure modes.

Prompt injection and security

Users can manipulate your AI's behavior through carefully crafted inputs — making it ignore instructions, reveal system prompts, or produce harmful output. Input sanitization and output validation are essential.

Rate limiting and queuing

LLM APIs have rate limits. When many users make requests simultaneously, you need a queue system to manage the flow and provide feedback to waiting users. Without this, users get API errors during peak usage.

Output quality control

LLM responses aren't deterministic — the same prompt can produce different quality results. You need output validation, retry logic for poor responses, and potentially human review for critical outputs.

What we review

Our ai wrapper / llm app audit covers these critical areas.

API key security — LLM API keys stored server-side, never exposed to client

Cost controls — per-user limits, token counting, usage monitoring

Streaming implementation — proper SSE/streaming for LLM responses

Error handling — timeouts, rate limits, model errors, malformed output

Prompt injection protection — input sanitization, output validation

Rate limiting — user-level and application-level limits

Caching — caching identical or similar requests to reduce costs

Monitoring — cost tracking, latency tracking, error rates

Frequently asked questions

How do I keep API costs under control?

Three strategies: 1) Set per-user usage limits to prevent abuse. 2) Cache responses for identical or similar prompts. 3) Optimize prompts to use fewer tokens — shorter system prompts, focused user prompts, and appropriate model selection (use a cheaper model for simple tasks).

How do I handle prompt injection?

Sanitize user input before including it in prompts. Use structured prompts that separate instructions from user content. Validate output before displaying it. Set up monitoring to detect unusual behavior. There's no perfect solution — it's about layered defenses.

Should I use OpenAI or Anthropic?

Both are excellent. OpenAI (GPT-4) has a larger ecosystem and more integrations. Anthropic (Claude) often produces better results for complex reasoning and longer contexts. Many production apps use both — routing different tasks to different models based on cost and quality.
