# Track 06: OpenAI & the Model Landscape

The first heavily API-driven track: every OpenAI endpoint you'll
actually use, then the wider provider landscape (Anthropic, Google,
open-weight models via Hugging Face), small language models and
on-device inference, and how pricing and rate limits shape system
design. From here on, every track builds on real API calls.
