LLM Tokenization & Pricing FAQs
Why is output (completion) cost higher than input?
Generating new tokens requires sequential autoregressive generation on GPUs, whereas input prompt tokens can be processed in parallel during the prefill phase.
How can I reduce my AI API costs?
Use concise system prompts, trim unnecessary conversation history, utilize few-shot examples sparingly, and use high-speed models like GPT-4o Mini or Gemini Flash for routine tasks.
What is local offline LLM cost?
Running open-weight models (like LLaMA 3, Mistral, or DeepSeek-R1) via LM Studio or Ollama on your own machine costs $0.00 in API fees with 100% data privacy.
