Understanding Halfred's key concepts including model profiles, pricing, credits, and tokens for optimal AI integration.
What You'll Learn
This section covers the fundamental concepts you need to know:
Model Profiles - How Halfred simplifies model selection with curated profiles
The Halfred Philosophy
Halfred was built on a simple principle: developers shouldn't need to become AI experts to build AI-powered features.
Instead of:
Comparing dozens of models
Managing multiple provider accounts
Worrying about which model is best for each task
Dealing with different APIs and billing systems
You get:
Profile-based selection - Choose based on your needs (speed, cost, quality)
Automatic routing - Halfred picks the best model behind the scenes
Unified interface - One API for all providers
Transparent pricing - Simple prepaid credit system

Credits & Billing
Prepaid system: Add credits before use
No surprises: You can't spend more than your balance
Transparent costs: Each request shows token usage and price
Flexible packages: Buy credits as needed
→ Learn more about pricing
What: Small units of text that models process
Why it matters: Billing is based on tokens
Context limits: Each profile has a maximum token capacity
Optimization: Shorter prompts = lower costs
