Smart routing: lite vs. full prompts
Voxcode automatically decides how much context to send with each request based on query complexity.- Simple queries — short questions, quick edits, single-line changes — use a lite system prompt. This reduces the token count and makes responses significantly faster.
- Complex queries — multi-file generation, architecture questions, component scaffolding — use the full system prompt, which includes complete project context and detailed instructions.
Prompt caching
When you continue an existing conversation, Voxcode uses prompt caching to avoid re-processing the same context on every message. Repeat conversations and iterative sessions are 30–50% faster than a fresh start, and consume fewer credits because the cached portion of the prompt is not re-billed at full rate.Free models are available on all plans. Beta models (excluding the two free Beta models) require a Starter plan or higher. Premium models require a Starter plan for limited access (2 models) or a Premium plan for full access.
