# Twitter Thread: A3M Router Launch

## Tweet 1/10 - The Hook
Our OpenAI bill hit $2,400 last month.

We're 5 people. 1,000 queries/day. Customer support, code gen, summarization.

We were using GPT-4 for everything. Even simple questions that any model could answer.

So we built a router. Cut costs by 70%. Open sourced it 🧵

## Tweet 2/10 - The Problem
The issue wasn't OpenAI. GPT-4 is great.

The issue was using it for EVERYTHING:

"How do I reset my password?" → GPT-4 ($0.03)
"Summarize this email" → GPT-4 ($0.02)
"Write Python function" → GPT-4 ($0.05)

We were paying Ferrari prices for grocery runs.

## Tweet 3/10 - The Insight
Not every query needs the premium model.

Simple Q&A → Any decent model works
Code generation → Speed matters more than perfection
Complex reasoning → That's where you need GPT-4

We needed something that routes each query to the right provider.

## Tweet 4/10 - The Solution
Built A3M Router:

```javascript
const { createA3MRouter } = require('adaptive-memory-multi-model-router');

const router = createA3MRouter();

// Analyzes query, picks optimal provider
const result = await router.route("Your query");
// Returns: cheapest capable provider + fallbacks
```

Zero config. Works immediately.

## Tweet 5/10 - How It Works
1. Analyze query (code? math? simple?)
2. Check provider profiles (cost, speed, quality)
3. Route intelligently
4. Track costs + fallback if needed

Simple → cheap provider
Code → fast provider
Complex → premium provider

## Tweet 6/10 - The Results
After 30 days:

Before: $2,400/month (GPT-4 only)
After: $720/month (mixed providers)

Savings: 70% 🎉
Speed: 2x faster
Quality: 94% (vs 100% GPT-4)

Trade-off: 6% quality for 70% savings

## Tweet 7/10 - Real Examples
Customer support: "Reset password?"
Before: GPT-4 ($0.03, 2.1s)
After: Cheapest provider ($0.001, 0.8s)
Savings: 97%

Code: "Write Python function"
Before: GPT-4 ($0.05, 2.1s)
After: Fast provider ($0.0004, 0.4s)
Savings: 99%, 5x faster

## Tweet 8/10 - What You Get
Out of the box:
• 12 providers configured
• Automatic routing
• Cost tracking
• Provider fallback
• Batch processing
• Response caching
• CLI tools

npm install adaptive-memory-multi-model-router

## Tweet 9/10 - Try It
```bash
# See routing decisions
npx a3m-router route "Your query"

# Compare providers
npx a3m-router compare "Write Python to sort"

# Benchmark everything
npx a3m-router benchmark
```

## Tweet 10/10 - CTA
872+ weekly downloads. 33 tests passing. Production-ready.

If your LLM bill is >$500/month, you're probably overpaying.
