Grok 4.5 is not just another benchmark launch. I ran the pricing math across coding agents, cache hits, tool calls, and EU access caveats.

xAI releases Grok 4.5, trained on tens of thousands of Nvidia GB300 GPUs. In coding benchmarks, the model trails Fable 5 and GPT-5.5 but needs 4.2 times fewer tokens than Opus…

SpaceXAI's new coding model is cheaper and faster than Anthropic and OpenAI's flagships—and by Musk's own account, at least one generation behind.

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…
