BYOM (Bring Your Own Model)
A pricing pattern where the user supplies their own API key for the underlying LLM provider (OpenAI, Anthropic, Google, OpenRouter) and the platform passes the model cost through at zero markup. VULK supports BYOM on Pro and above.
BYOM (Bring Your Own Model)
BYOM — Bring Your Own Model, sometimes written BYOK (Bring Your Own Key) — is the option to plug a personal API key from OpenAI, Anthropic, Google AI Studio, OpenRouter, or DeepSeek directly into the generation platform, so the model usage is billed against the user's account at provider list price rather than re-sold by the platform with a margin. For heavy users this can cut the effective cost of generation by 40-60%.
In VULK, BYOM is unlocked on Pro and higher. The user pastes their key in Settings → BYOM, picks which provider routes to which task tier, and from then on every generation routes through their key with zero markup. VULK still operates the agent loop, prompt engineering, quality gate, and Firecracker preview — it just stops paying for the model. Internally code uses both BYOM (user-facing) and BYOK (legacy column name) — both refer to the same feature.
See /docs/account/byok.
Firecracker microVM Preview
VULK's live preview system — every generated project runs in an isolated Firecracker microVM with sub-second cold-start, full Node + Vite, and a public URL. Replaces fragile WebContainer / iframe sandboxes.
Auto-CRUD API
A backend pattern where Create / Read / Update / Delete endpoints are generated automatically from a database schema or entity manifest, instead of being hand-written per resource. VULK uses auto-CRUD via vulk-api-engine.
