Always call GET /api/v2/models/supported?targetAccountId=... before selecting a model. The response provides exact model identifiers, providers, reasoning support, and Fast-mode compatibility for the selected account.

​
Agent fields

  • agentModel is the primary model for conversations and Computer Agent work.
  • With agentS2SEngine:"openai-live", agentModel is the delegation model used for reasoning and tool decisions while GPT Live handles real-time audio.
  • agentThinking enables a supported reasoning budget on a reasoning-capable primary model. Use null to disable it.
  • agentThinkingModel selects the model used by Pause & Think and optional post-conversation reasoning.
  • postConvoForceThinking uses the thinking model for summaries, reporting, and similar post-conversation work when the primary model is not already reasoning-enabled.

​
Fast processing

agentFastMode is optional and disabled by default. Enable it only when the selected model reports supportsFastMode:true. Vida then requests OpenAI Fast processing for compatible model calls, including GPT Live delegation. Billing follows the service tier OpenAI actually returns, so confirm the account’s product plan before enabling it for customer traffic. Model availability can vary by account and compliance requirements. Store the exact identifier returned by discovery; do not copy a static model list into an integration. After updating staging, read it again and confirm the selected model and reasoning settings. Test latency and behavior before publishing.
