Smart Routing Strategy
Don't pick one model. Use the right model for each task:
import { CostLens } from 'costlens';
const client = new CostLens({
apiKey: process.env.OPTIRELAY_API_KEY,
routing: {
// Simple tasks → Cheapest models
classification: 'claude-3-haiku',
summarization: 'gpt-3.5-turbo',
// Moderate tasks → Balanced models
content: 'claude-3-sonnet',
analysis: 'gemini-1.5-pro',
// Complex tasks → Premium models
reasoning: 'gpt-4-turbo',
code: 'claude-3-sonnet'
}
});
// Automatically routes to optimal model
const resp client.chat.completions.create({
messages: [{ role: 'user', content: prompt }],
task: 'classification' // Uses claude-3-haiku
});
