AI Model
A trained algorithm that takes inputs (text, images, data) and produces outputs (predictions, classifications, generated content).
What is AI Model?
An AI model is a trained algorithm that processes inputs and produces useful outputs.
Think of it as the brain that powers AI features. You feed it data (text, images, code, numbers), and it returns predictions, classifications, or generated content based on patterns it learned during training.
Most builders interact with models through APIs like OpenAI, Anthropic, or Google AI. You pick a model (GPT-4, Claude 3.5, Gemini), send it a prompt, and get back a response. Different models excel at different tasks: some are better at code, others at creative writing, some at analyzing images.
Pricing varies wildly. GPT-4 costs around $30 per million input tokens. Claude 3.5 Sonnet runs about $3 per million. Smaller models like GPT-3.5 or Gemini Flash cost pennies. Open-source models like Llama 3 are free to run yourself but require infrastructure.
Good to Know
Models are trained on massive datasets to learn patterns, then frozen and used for inference
Different model types: language models (GPT, Claude), vision models (DALL-E, Midjourney), multimodal models (GPT-4V, Gemini)
Model size matters: larger models (GPT-4) are smarter but slower and pricier; smaller models (GPT-3.5) are faster and cheaper
You can fine-tune existing models on your own data or use pre-trained models via API
Open-source models (Llama, Mistral) let you run locally or customize fully, but require more technical setup
