Integrate Narev with Helicone for LLM Cost Optimization
Import production traces from Helicone into Narev to test and validate model optimizations. Reduce LLM costs by 99% using real production data through systematic A/B testing.
Helicone shows you what's happening. Narev shows you what to change. Helicone captures every LLM interaction in production, giving you visibility into costs, latency, and usage patterns. Narev uses those exact traces to test optimizations before you deploy them.
The Problem with Observability Alone
Helicone is an excellent LLM observability platform—it gives you complete visibility into your production LLM usage. You can see exactly:
- Which requests are most expensive
- Where latency bottlenecks occur
- Which models you're using and how often
- Total costs broken down by user, session, or endpoint
- Detailed request and response metrics
But observability alone doesn't solve the problem. Seeing the problem isn't the same as fixing it.
When Helicone shows you're spending $10,000/month on GPT-4, you're left wondering:
- Can I switch to a cheaper model without breaking quality?
- Which of the 400+ available models would work for my specific use case?
- Will GPT-4o Mini handle my prompts as well as GPT-4?
- Should I adjust my prompts or change models?
The result? Teams have full observability but still overspend by 10-100x because they lack a systematic way to test alternatives.
How Narev + Helicone Work Together
Narev and Helicone are the perfect pairing for LLM optimization:
Tool | Purpose | What It Tells You |
---|---|---|
Helicone | Monitor production LLM usage | "You're spending $10K/month on GPT-4" |
Narev | Test alternatives systematically | "Switch to GPT-4o Mini and save $9K/month" |
The workflow:
- Monitor production with Helicone to identify optimization opportunities
- Import traces from Helicone into Narev
- Test alternative models, prompts, and parameters with A/B experiments
- Deploy validated optimizations to production with confidence
- Verify improvements in Helicone and repeat
Integration Guide
Step 1: Export Production Traces from Helicone
Narev integrates directly with Helicone to import your production traces. These traces become the test dataset for your experiments—ensuring you're testing against real-world usage patterns.
To connect Helicone:
-
In Narev, go to Import Traces
-
Select Helicone as your provider
-
Enter your Helicone project credentials:
- Project Name: Your Helicone project identifier
- API Key: Your Helicone API key (starts with sk-helicone-...)
-
Select your date range (default: last 7 days)
-
Click Save Project to import traces
Narev will import your prompts, model configurations, and usage patterns to create realistic test scenarios.
Step 2: Identify Optimization Opportunities
Use Helicone to spot areas where optimization would have the biggest impact:
💰 High-Cost Requests
Which endpoints or users consume the most tokens? These are prime candidates for model switching.
⚡ Latency Bottlenecks
Where are users waiting? Test faster models to improve response times.
📊 High-Volume Sessions
Which sessions or features run most frequently? Small optimizations here yield big savings.
Step 3: Create Experiments with Real Production Data
Let's say Helicone shows you're spending heavily on a content generation feature using GPT-4. Import those traces to Narev and test alternatives:
Create an experiment comparing:
Variant A (Current)
claude-3-5-haiku-20241022
Variant B (Test)
gpt-4o-mini
Narev will run both variants on your actual production prompts from Helicone and measure:
- Cost savings in dollars and percentage
- Latency differences (time to first token, total time)
- Quality metrics (accuracy, completeness, formatting)
Step 4: Analyze Results with Statistical Confidence
Narev provides clear, data-backed answers:
Example results:
- ✅ GPT-4o Mini costs 49% less ($18.36 vs $35.85 per 1M requests)
- ✅ Quality improved by 33% (80% vs 60%)
- ✅ Latency improved by 13% (623.4ms vs 713.4ms)
Projected savings: Based on your Helicone volume data, switching to GPT-4o Mini reduces costs by nearly 50% while improving both quality and latency.
Step 5: Deploy and Monitor
With validated results, confidently deploy your optimization:
// Before: Current model from Helicone traces
import Anthropic from "@anthropic-ai/sdk";
const anthropic = new Anthropic({
apiKey: process.env.ANTHROPIC_API_KEY,
baseURL: "https://anthropic.helicone.ai",
defaultHeaders: {
"Helicone-Auth": `Bearer ${process.env.HELICONE_API_KEY}`,
},
});
const response = await anthropic.messages.create({
model: "claude-3-5-haiku-20241022", // ← Old model
messages: [{ role: "user", content: userMessage }],
});
// After: Switch to validated alternative
import OpenAI from "openai";
const openai = new OpenAI({
apiKey: process.env.OPENAI_API_KEY,
baseURL: "https://oai.helicone.ai/v1",
defaultHeaders: {
"Helicone-Auth": `Bearer ${process.env.HELICONE_API_KEY}`,
},
});
const response = await openai.chat.completions.create({
model: "gpt-4o-mini", // ← Tested winner
messages: [{ role: "user", content: userMessage }],
});
Monitor the impact in Helicone:
- Cost reduction appears immediately in your Helicone dashboards
- Track quality through user feedback and error rates
- Compare before/after metrics to validate experiment predictions
Step 6: Continuous Optimization
Use this workflow continuously:
- Weekly: Review Helicone for new optimization opportunities
- Test: Import the highest-cost traces into Narev
- Validate: Run experiments on new models or prompt variations
- Deploy: Roll out proven optimizations
- Repeat: As new models launch or usage patterns change
