Grok 4.5 is arguably #1 when taking speed and cost into account
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

On intelligence per dollar basis Grok 4.5 looking brilliant. AI. At $0.31 per Intelligence Index task (of Artificial Analysis), it delivers near-frontier performance at roughly 1/9 the cost of Claude Fable 5, 1/6 the cost of Claude Opus 4.8, and about 1/3 the cost of GPT-5.6 Sol or Kimi K3. That’s more relevant with the token-consumption data. Grok 4.5 uses nearly 6X fewer tokens than Fable 5 while still being near the top of the ranking, onFrontierSWE. For many real-life AI applications this is better than a small lead on a benchmark. Lower cost per completed task means cheaper agents, higher usage limits, faster testing and better margins at scale. The frontier model race must shift from “raw intelligence” to “efficient intelligence”.

Grok 4.5 uses less tokens than any other big model, performance great on almost all tasks, cost you cheaper than any big model, finishes the task faster than others. Makes me happy :)
you should give Grok 4.5 a try
Grok 4.5 is only 1.5T parameters. Kimi K3 is 2.8T... and costs 3× more per task. SpaceXAI cracked intelligence efficiency. Now imagine Grok at 3T.
