🚀 GPT-5 is now available in Release0: Build smarter agents, faster

You can now use OpenAI’s latest and most powerful language models — GPT-5, GPT-5-mini, and GPT-5-nano — in your Release0 agents.

Whether you're building sales bots, support assistants, onboarding flows, or multi-step automations, these new models unlock stronger reasoning, faster performance, and more cost control.


🔢 Overview of GPT-5, GPT-5-mini, and GPT-5-nano in Release0

Here’s a quick overview of the GPT-5 family now available in the OpenAI block:

ModelDescriptionBest For
GPT-5Full-power model with advanced reasoningPremium assistants, complex chat automations
GPT-5-miniLightweight model, good balance of cost & qualityOnboarding flows, surveys, multi-language UX
GPT-5-nanoFastest and cheapest, good for high-volume botsLead capture, routing, basic support

To use any of these models, select them from the Model dropdown in the OpenAI block inside the agent editor.

⚠️ Note: If you are using the family model GPT-5, there is an additional requirement you need to fulfill in your OpenAI account. Your organization must be verified to stream this model.

  1. Go to OpenAI’s organization settings
  2. Click on Verify Organization
  3. Follow the verification steps provided by OpenAI
  4. Wait up to 15 minutes for access to propagate

Without this verification, GPT-5 models family requests may fail silently or return authentication errors.


⚡ Best Use Cases for GPT-5 Family Models

Here’s how each model performs best in different Release0 scenarios:

  • GPT-5 → Create high-end AI agents with deep logic and rich, multi-turn conversations — ideal for sales and complex support.
  • GPT-5-mini → Use for dynamic onboarding, multilingual forms, or responsive UI flows.
  • GPT-5-nano → Deploy in massive-scale automations like lead funnels, routing bots, or newsletter integrations.

💡 Pro Tip: Combine GPT-5 models to maximize efficiency

You can chain multiple OpenAI blocks in Release0 — which means you can:

  • Use GPT-5-nano for quick classification
  • Then call GPT-5 for rich response generation only when needed

This gives you performance without sacrificing cost-efficiency.
