Free, project-first programming courses with an AI coding tutor
Lessons are anchored in engaging projects with genuine use cases, so what you build is useful rather than purely academic.
Move between topics freely and forge your own route through the material instead of being locked to one fixed order.
Paste or write code and the assistant looks through it, flags mistakes and suggests improvements with explanations and examples.
Ask the tutor to walk through a tricky problem in stages rather than simply revealing the final solution.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
