Benchmark estimates put Grok 4.5 at $2.49 per coding task versus $5.07 for GPT-5.5 in Codex and $11.80 for Fable 5 in Claude Code; analysts say real-world enterprise testing remains key.

Elon Musk said the latest version of Grok is “faster, more token-efficient and lower cost” than one of Anthropic’s models.

Grok 4.5 is SpaceXAI's smartest model built for coding, agentic tasks, and knowledge work.
