# OpenAI GPT-5.6 Models Now Available

OpenAI released the GPT-5.6 family. We have automatically transitioned all GPT-5.4 users to the same-priced GPT-5.6 Terra - here is what it means for your analytics and your bill.

OpenAI launched the **GPT-5.6** family - a new quality and efficiency baseline - and we have already updated AI Data Stream to support it. If you were using GPT-5.4 models, you have been **automatically transitioned** with **no change to what you pay** - no action needed on your part.

## What Changed for You

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

- **GPT-5.4** → **GPT-5.6 Terra**
- **GPT-5.4 Pro** → **GPT-5.6 Sol**
- **GPT-5.2** → **GPT-5.6 Terra**
- **GPT-5.2 Pro** → **GPT-5.6 Sol**

Your API key, settings, and conversations all remain the same. GPT-5.4 and GPT-5.4 Pro have been retired in favour of the newer GPT-5.6 family.

## No Bill Shock

The GPT-5.6 family shifts the naming by a tier, so we mapped the migration to protect your costs rather than your model name:

- **GPT-5.6 Terra** is priced **identically** to the old GPT-5.4 - **$2.50 / $15** per million input / output tokens. Everyday GPT-5.4 users pay exactly what they paid before, on a newer model.
- **GPT-5.4 Pro** cost **$30 / $180** per million tokens. It now maps to **GPT-5.6 Sol** at **$5 / $30** - a substantial reduction for the same top-tier workload.

Standard pricing for the full family:

- **GPT-5.6 Sol** - $5 / $30 per million tokens (input / output)
- **GPT-5.6 Terra** - $2.50 / $15
- **GPT-5.6 Luna** - $1 / $6

As always, AI Data Stream is bring-your-own-key: you are billed by OpenAI directly at their published rates.

## What Is New in GPT-5.6

GPT-5.6 is OpenAI's **new quality and efficiency baseline**, with improved token efficiency - meaning it often reaches the same answer using fewer tokens, which lowers real-world cost beyond the headline price. The family comes in three tuned variants:

### GPT-5.6 Sol

The flagship, frontier-capability model for the most demanding analytics - correlating data across multiple sources, in-depth investigations, and comprehensive report generation.

### GPT-5.6 Terra

Strong performance at a balanced price. This is the workhorse for day-to-day analytics conversations and the automatic home for former GPT-5.4 users.

### GPT-5.6 Luna

Efficient and fast for high-volume, lighter-weight tasks where speed and cost matter most.

## The Full OpenAI Lineup

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

- **GPT-5.6 Sol** - Most capable, frontier model
- **GPT-5.6 Terra** - Balanced performance and price
- **GPT-5.6 Luna** - Fast and cost-efficient
- **GPT-5 Mini** - Fast, budget-friendly
- **GPT-4o** - Reliable previous generation
- **GPT-4o Mini** - Budget-friendly option

## Reasoning Effort Control

The GPT-5.6 models support **reasoning effort control**. 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-5.6 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.
