OpenAI GPT-5.6 Models Now Available

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.
