Responsive mobile web interface for AI Agents, continuous multi-scene video generation, and integration of Gemini 3 and Byteplus models.

See what’s new and improved in our latest update.

### AI Agentic Responsive Mobile Interface

* Access and converse with your autonomous AI Agents seamlessly from any mobile browser on iOS and Android devices.
* Touch-optimized controls, virtual keyboard adaptation, and fluid message streaming provide a native app feel without downloading an app.
* Review agent execution plans, inspect tool calls, and approve automated steps on the go.

### Video Generator "Last Frame Image" Scene Chaining

* New toggle in Video Generation nodes (supporting Byteplus and BYOK providers) that automatically captures and outputs the `last_frame_url`.
* Pass the ending frame directly into the next scene's prompt to generate continuous, multi-scene video stories with consistent character and background continuity.
* Eliminates disjointed transitions in automated AI video storytelling pipelines.

### Frontier Model Integrations: Gemini 3, Byteplus & GPT-5-mini

* **Google Gemini 3:** Native integration delivering enhanced multimodal comprehension, faster response times, and expansive context windows.
* **Byteplus Models:** Direct API access for high-speed creative text and visual generation.
* **GPT-5-mini:** Available in the OpenAI Private Key node, offering an optimal balance of intelligence, low latency, and reduced credit consumption.

### Customizable Chatbot Widget Button Text

* Workspace admins can now freely customize the launcher button text on embedded website chat widgets (e.g., *"Ask our AI"*, *"Talk to Support"*, *"Instant Quote"*).
* Increases engagement and click-through rates by aligning the chatbot CTA with specific landing page goals.
