GPT-6 Astra
A good performance / EU-hosting balance for a European company.
Overview
GPT-6 Astra is OpenAI's latest general-purpose model, built around coding, agentic workflows and an always-on reasoning mode, with a context window said to reach one million tokens - a figure OpenAI has not yet confirmed. It ships first through a Trusted Access Program limited to enterprise customers, so independent testing remains scarce at launch. Like the rest of OpenAI's lineup, it runs on US-based infrastructure with no on-premise option, meaning data leaves the EU by default unless a specific contract states otherwise.

Three independent measures
What people prefer, what the model can do, what the market uses. Each source has its biases and none is enough on its own: we show them side by side, never blended.
Strengths
- World-class on Arena
- Very long context
Limitations
- High output cost
Who is it for
- your data must stay in the EU
- your budget is tight
Ideal use cases
- Complex business agents
- AI-assisted code review
- Long document analysis
- Multi-step automation
- Continuous critical reasoning
