License
Apache-2.0

The vendor reports 29B total and 4B active parameters, public Apache-2.0 weights, Transformers custom code and serving instructions. The native contract toggles enable_thinking; it does not declare distinct effort levels. Configure one enabled mode, using medium as the OpenRouter transport setting, plus thinking disabled, rather than publishing invented low/high differences. Phala is the current free-route provider and publishes training=false, retainsPrompts=false. Keep the exact :free execution ID; facts and fallback release-date keys use the base ID. Fallback date records this onboarding request date.
