How We Cut Our LLM Costs by 85%
(Without Changing a Single Prompt)
Last week, our AI agents burned $45 in a single day. Not because they were doing something complex — but because a health check was sending "are you alive?" to Claude Opus every 30 minutes. At $15 per million tokens, that little ping cost us $40/day.
That's when we decided to build HiWay2LLM.
The Problem Every AI Developer Has
If you're building with LLMs, you probably pick the best model because you want reliable outputs. Makes sense. But here's the thing: 70% of your requests don't need the best model.
- "Bonjour" → Does this need Opus? No.
- "What time is it in Paris?" → Does this need Sonnet? No.
- "Summarize this email" → Maybe Haiku is fine.
- "Refactor this 500-line module and deploy" → OK, now you need Sonnet.
You're paying premium prices for greetings. Every. Single. Time.
The Numbers That Hurt
| Daily cost | $45 |
| Monthly cost | $1,350 |
| Average tokens per request | 142,000 (!) |
| Requests routed to cheap models | 0% |
What We Built
HiWay2LLM is a proxy that sits between your app and your LLM provider. It analyzes every request in under 1 millisecond and routes it to the optimal model.

Guardian: The Anti-Loop System That Saved Us $40/Day
After living through the health check nightmare, we built Guardian — a real-time protection layer that catches the patterns that silently drain your budget.
Health Check Loops
Same request hitting your API every 30 minutes? Guardian fingerprints requests and blocks duplicates. Our $40/day incident? Killed in the first hour.
Context Bloat
Your agent's prompt growing from 10K to 142K tokens? Guardian warns at 50K, throttles at 100K, blocks at 200K. No more runaway context.
Zombie Agents
An automated agent running at 3am with no human interaction? Guardian detects off-hours activity and blocks it.
Cost Spikes
Spending 3x your hourly average? Guardian throttles before the damage is done. You get a notification, not a surprise bill.
Every rule is toggleable. You set the thresholds. We're guardrails, not a firewall.
Advanced Budget Controls: What No Provider Offers
After building Guardian, we realized reactive protection isn't enough. You need proactive budget control — the ability to define exactly how your money should be spent, before it's spent.
We built something no LLM provider offers:
- $Daily and monthly caps — hard limits that block requests when reached. No surprises.
- $Per-model limits — max $2/day on Opus, unlimited on Haiku. Control where the money goes.
- $Off-hours rules — nights and weekends? Haiku only, $0.50/hour max. Your staging environment can't burn your budget overnight.
- $Automatic degradation — at 80% of daily budget, downgrade to cheaper models. At 95%, Haiku only. At 100%, block. Smooth, not sudden.
- $Max per request — no single request can cost more than $0.50. Prevents 200K-token prompt bombs.
Why don't Anthropic or OpenAI offer this? Because they sell tokens — the more you spend, the better for them. We make money when you save money. Our incentives are aligned with yours.

How to Get Started
Change one line of code. Point your base_url to HiWay2LLM. Works with OpenAI SDK, LangChain, Vercel AI SDK, n8n, curl — anything OpenAI-compatible.
We charge a 5% fee on routed tokens. No subscription. No minimum. You save way more than you pay.
No credit card required
HiWay2LLM is built by Mytm-Group, a French AI company. The name? Highway to Hell. AC/DC. Because that's where your LLM budget goes without smart routing. 🤘
