Cost Intelligence

Stop guessing your AI infrastructure spend

Track and compare costs in real time.

Token-based estimates are outdated. Bear Lumen hooks asynchronously into your AI architecture to map exact infrastructure costs down to specific requests, features, and custom parameters, with zero latency overhead.

The Core Problem

Blended margins hide where your AI product bleeds money

Before Bear Lumen

Blended cloud margins hide unprofitable agentic loops. Engineering teams are blind to which user queries or heavy tool-calls are bleeding money until the monthly cloud billing invoice arrives.

  • Monthly billing surprises with no real-time visibility
  • Token estimates miss actual compute and routing costs
  • No attribution by user, feature, or workflow phase
  • Runaway agentic loops invisible until invoice day
With Bear Lumen

Continuous cost observability. Our system ingests metadata asynchronously to map multi-provider rate cards instantly to active requests. You capture real-time cost-to-serve metrics while preserving your core application's execution performance.

  • Real-time per-request cost attribution, always
  • Exact dollar mapping across all LLM providers
  • Custom dimensions: user, workspace, workflow phase
  • Surface unprofitable loops the moment they start


Developer-First Implementation

Drop in the SDK. Start tracking in minutes.

Initialization is a few lines. After that, every tracked response carries its own cost attribution, and exact cost schemas are queryable straight from the SDK.

import OpenAI from 'openai';
import { BearLumen } from '@bearlumen/node-sdk';

const openai = new OpenAI();
const bear = new BearLumen({ apiKey: process.env.BEAR_LUMEN_API_KEY });

const response = await openai.chat.completions.create({
  model: 'gpt-4o',
  messages,
});

// Attribute cost to a user, feature, and custom dimensions
bear.track(response, {
  userId: 'user_123',
  feature: 'doc_parse',
  metadata: { workflowPhase: 'extraction' },
});

// Query exact cost allocations programmatically
const costs = await bear.costs.summary();

Business Impact

From cost blindness to strategic clarity

Eliminate Underwater Accounts

Instantly surface runaway loops and high-volume accounts that are costing more to support than their subscription fee brings in.

Spot overspend before it compounds, by customer, feature, and model

Data-Backed Product Strategies

Feed actual historical data directly into your backend architecture to test alternative graduated or volume pricing models before migrating users.

Test volume and tiered models on real history before you migrate users

Enterprise Security Focus

Your live text data stays yours. Bear Lumen strictly ingests non-identifiable usage tokens and processing metadata over secure, certified connections.
