LLM Observability & Cost Control

Aden provides SDKs for TypeScript and Python that automatically track every LLM API call in your application - usage, latency, costs - and give you real-time controls to prevent budget overruns.

TypeScript SDK

Instrument OpenAI, Anthropic, and Gemini in Node.js applications.

Python SDK

Track LLM usage in Python with support for FastAPI, Django, and more.

​
Key Features

Multi-Provider Support

Works with OpenAI, Anthropic Claude, and Google Gemini with a single integration.

Zero Code Changes

Automatic instrumentation - just call instrument() once at startup.

Real-Time Cost Control

Set budgets, throttle requests, and automatically degrade to cheaper models.

OpenTelemetry Compatible

Trace IDs, span IDs, and agent stacks for multi-agent observability.

​
Quick Start

import { instrument, createConsoleEmitter } from "aden";
import OpenAI from "openai";

// Instrument at startup
await instrument({
  emitMetric: createConsoleEmitter({ pretty: true }),
  sdks: { OpenAI },
});

// Use your SDK normally - metrics captured automatically
const openai = new OpenAI();
const response = await openai.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "Hello!" }],
});

​
What Gets Tracked

Every LLM API call is captured with comprehensive metrics:
MetricDescription
input_tokensPrompt/input tokens used
output_tokensCompletion/output tokens generated
cached_tokensTokens served from prompt cache
latency_msRequest duration in milliseconds
modelModel name (e.g., gpt-4o, claude-3-5-sonnet)
providerProvider name (openai, anthropic, gemini)
tool_callsFunction/tool calls made
trace_idOpenTelemetry-compatible trace ID
agent_stackNamed agent context for multi-agent systems

​
Cost Control Actions

Prevent budget overruns with real-time controls:
ActionEffect
allowRequest proceeds normally
blockRequest rejected when budget exhausted
throttleRequest delayed for rate limiting
degradeSwitch to cheaper model when approaching budget
alertProceed with notification at warning threshold
