Grok 4.5在成本效率方面取得突破性进展,单任务成本仅为竞品的1/3到1/9
展开原文
On Artificial Analysis, it costs just $0.31 per Intelligence Index task while delivering frontier intelligence
For comparison:
• Claude Fable 5 (max): $2.75
• Claude Opus 4.8 (max): $1.80
• GPT-5.6 Sol (max): $1.04
• Kimi K3: $0.95
• Grok 4.5: just $0.31
That makes Grok 4.5 roughly:
• Nearly 9× cheaper than Claude Fable 5
• Nearly 6× cheaper than Claude Opus 4.8
• 3× cheaper per task than Kimi K3
• 3.4× cheaper than GPT-5.6 Sol
On FrontierSWE, Grok 4.5 also used nearly 6× fewer total tokens per task than Fable 5 while still ranking near the very top
SpaceXAI has figured out how to deliver top-tier intelligence with extraordinary token efficiency
At this level of performance, no other frontier model is operating in the same cost-efficiency league
Grok 4.5 does not brute-force every problem with endless tokens and compute
It makes every token and every dollar work harder
