Grok 4.5’s efficiency is ridiculous 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
