Frequently Asked Questions
How much does it cost to use GPT or Claude?
Costs depend on the model and usage. A typical chatbot message (~500 input + 300 output tokens) costs $0.001-$0.006 depending on the model. At 1,000 messages/day, expect $1-6/day. Use cheaper models (Haiku, GPT-4o-mini) for simple tasks and premium models only when quality matters.
What is a token in AI?
A token is the basic unit that language models process. In English, one token is roughly 4 characters or 0.75 words. 'Hello, world!' is about 4 tokens. The word 'calculator' is 3 tokens. APIs charge per token for both input and output, with output typically costing 3-5× more.
How much does it cost to fine-tune a model?
Fine-tuning a 7B parameter model costs roughly $10-100 on cloud GPUs. A 70B model runs $500-5,000. Training from scratch is dramatically more expensive: $100K-500K for a 7B model, and $50M+ for GPT-4 class models. Fine-tuning is almost always the right starting point.
