Grok 4.5
A versatile model, balanced across most use cases.
Overview
Grok 4.5 is xAI's agent-oriented model, built to chain complex tasks such as coding and automation, with a 500,000-token context window and competitive API pricing ($2/$6 per million tokens). Its agentic focus and speed make it a plausible fit for developer tooling and workflow automation, but it remains a closed, proprietary model with no open weights or on-premise option — data runs through xAI's US infrastructure, a real consideration for European buyers with data-residency constraints.

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
- No documented EU residency
Who is it for
- you handle sensitive data with no EU option
Ideal use cases
- Agentic workflow automation
- Software development agents
- Long-document analysis
- Cost-sensitive API integration
