Who should pick which
- Enterprise RAG engineerPick: Voyage AI
Voyage AI's domain-specific models (finance, legal, code) and 32K context are ideal for high-accuracy retrieval in regulated industries, with SOC 2/HIPAA compliance.
- AI coding agent developerPick: Mythos Router
Mythos provides verifiable file edit verification via SWD and signed receipts, preventing hallucinated changes. Free CLI fits developer workflows.
- Startup with limited budgetPick: Mythos Router
Mythos is free (MIT) and requires only an Anthropic API key. Voyage's contact pricing is prohibitive for small teams.

Voyage AI offers SOC 2 and HIPAA compliance, essential for sensitive data. Mythos is local but lacks formal compliance certifications.
- Multi-model AI tool userPick: Voyage AI
Voyage integrates with any vector DB or LLM. Mythos currently supports only Anthropic models (Claude Opus 4.8), limiting flexibility.
