LLM Cost Calculator

Q: Which LLM provider is cheapest?

It depends on your use case. For simple tasks, open-source models (Llama, Gemma) are cheapest. For complex reasoning, GPT-4 and Claude offer the best quality-per-dollar.

Q: How do I reduce LLM costs?

Use model routing, cache common queries, optimize prompts to reduce tokens, and use smaller models for simple tasks.

Q: Are open-source models good enough?

For many tasks, yes. Simple Q&A, classification, and extraction work well with smaller models. Complex reasoning still benefits from larger models.

Q: How does model routing work?

Route simple tasks to small, cheap models and complex tasks to larger, more capable models. This reduces overall cost while maintaining quality.

Compare LLM Pricing

Compare pricing across major LLM providers and estimate your monthly inference costs. Input your usage patterns to find the most cost-effective model for your needs.

Calculate LLM Cost See Model Routing Strategy

LLM costs range from $0.10–$0.60 per million tokens for small models to $5–$60 per million tokens for large models. The most cost-effective approach is model routing: use small models for simple tasks and reserve large models for complex reasoning. This can reduce costs 40–70%.

Cost Optimization Strategies

Budget Approach

Use smallest model that works
Cache common queries aggressively
Batch similar requests
Use open-source models where possible
Implement request throttling

Optimized Approach

Model routing (small + large)
Semantic caching
Prompt optimization to reduce tokens
Streaming to reduce timeout costs
Usage monitoring and alerts
