🚀 Release0 now supports OpenAI’s GPT-5 family of models#

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.

🔢 Supported GPT-5 Models#

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

Model	Description	Best For
GPT-5	Full-power model with advanced reasoning	Premium assistants, complex chat automations
GPT-5-mini	Lightweight model, good balance of cost & quality	Onboarding flows, surveys, multi-language UX
GPT-5-nano	Fastest and cheapest, good for high-volume bots	Lead 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.

⚡ Use Case Examples#

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

• GPT-5 → Build premium AI agents with deep logic, long context handling, and natural conversations. Perfect for sales assistants, complex support bots, and multi-turn dialogues.
• GPT-5-mini → Ideal for user-facing flows that require speed and reliability (e.g., onboarding, localized surveys).
• GPT-5-nano → Best for large-scale use cases like lead generation, newsletter bots, or traffic-routing assistants where cost-efficiency is key.

💡 Tip: Mix models in the same flow#

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.
