OpenAI GPT-5.4 Models Now Available

OpenAI launched GPT-5.4 and GPT-5.4 Pro this week, and we have already updated AI Data Stream to support them. If you were using GPT-5.2 models, you have been automatically transitioned - no action needed on your part.

What Changed for You

Nothing you need to do. AI Data Stream automatically migrates your model selection:

• GPT-5.2 → GPT-5.4
• GPT-5.2 Pro → GPT-5.4 Pro
• GPT-5.2 Instant → GPT-5 Mini

Your API key, settings, and conversations all remain the same. GPT-5.2 Instant has been retired by OpenAI and replaced by GPT-5 Mini, a faster and more cost-efficient model.

What Is Better in GPT-5.4

1M Token Context Window

GPT-5.4 offers a 1,050,000 token context window - ideal for feeding large datasets, lengthy conversation histories, or multiple reports into a single request.

Built-in Computer Use

GPT-5.4 is the first mainline OpenAI model with built-in computer use capabilities. While AI Data Stream does not use this directly, it reflects the model’s improved ability to understand and execute multi-step tasks - exactly what happens when the AI gathers data across your connected properties.

GPT-5.4 Pro

GPT-5.4 Pro uses additional compute to think harder on complex problems, producing smarter and more precise responses. This is ideal for in-depth analytics tasks like correlating data across multiple sources or generating comprehensive reports.

The Full OpenAI Lineup

With this update, the complete OpenAI model lineup in AI Data Stream is:

• GPT-5.4 - Most capable, frontier model
• GPT-5.4 Pro - Maximum intelligence for complex tasks
• GPT-5 Mini - Fast and cost-efficient
• GPT-4o - Reliable previous generation
• GPT-4o Mini - Budget-friendly option
• o3 - Deep reasoning
• o4-mini - Fast reasoning

Reasoning Effort Control

GPT-5.4 models support reasoning effort control, just like Claude 4.6. This lets you decide how much thinking the model does before answering:

• Low - Faster responses, lower cost
• Medium - Balanced speed and depth
• High - Thorough reasoning for complex analysis

You can set a team default in Settings > AI Providers for your OpenAI provider, and override it per message using the effort dropdown in the chat interface.

Switching Models

If you want to try GPT-5.4 or switch between models:

1. Go to Settings > AI Providers
2. Click your OpenAI provider
3. Select your preferred model from the dropdown
4. Save

Or simply select it from the model picker when starting a new conversation.
