Frequently Asked Questions about Logic
Can I write Logic agents in plain English without learning a framework?
Yes. Logic specs are written entirely in plain English, not code or YAML. You describe what the agent should do, what inputs it accepts, and what outputs it produces, then Logic generates a fully typed REST API and deploys it immediately. No SDKs or frameworks required.
How does Logic's version control work, and can I roll back an agent?
Logic uses Git-like version control, so every spec change creates a new version with transparent diffs. You can roll back to any previous version instantly if something breaks. Combined with built-in regression testing, this means you can iterate on agent behavior without fear.
Does Logic route requests across different AI models automatically?
Yes. Logic includes intelligent model routing that can automatically choose between OpenAI, Anthropic, Google, and Perplexity based on cost and latency. It also handles automatic failover if your primary model is unavailable, and caches results for deterministic tasks so repeated requests return instantly.
Can I use Logic agents inside Claude or Cursor without building custom integrations?
Yes. Logic runs as an MCP server, so you can integrate agents natively into Claude, Cursor, and ChatGPT without writing any glue code. You can also trigger agents via REST API for CI/CD pipelines or batch processing through CSV files.
