What is Magic.dev?
Magic.dev built a frontier coding model with the largest context window in the industry — 100 million tokens. That is enough to load most entire codebases (Linux kernel, React, etc.) into one prompt. Specialised purely for software engineering.
Key features
- 100M+ token context window (largest in industry)
- Trained exclusively on code + technical text
- Strong on cross-file refactors
- Enterprise focus
- Integration with popular IDEs via API
Pros
- Unmatched for whole-codebase tasks
- Token efficiency is genuinely impressive
- No need for RAG when whole repo fits
Cons
- Enterprise pricing — not for individuals
- API access only, no consumer UI
- Newer player vs entrenched Anthropic / OpenAI
