Output tokens cost $6.00 per million on Grok 4.5 and $3.10 per million on Longcat 2.0. Input tokens cost $2.00 per million on Grok 4.5 and $0.77 per million on Longcat 2.0. Cached input tokens are billed at $0.50 per million on Grok 4.5 and $0.02 per million on Longcat 2.0. Time to first token (TTFT) measured on AIHubMix is 1.9s on Grok 4.5 and 6.1s on Longcat 2.0. Measured output throughput is 26.7 tok/s on Grok 4.5 and 38.5 tok/s on Longcat 2.0.
Grok 4.5
Longcat 2.0Grok 4.5 was trained on datasets spanning knowledge in coding, science, engineering, and math. With both intelligent and efficient reasoning, Grok 4.5 excels at real engineering tasks and exceeds comparable leading models at these tasks.
Designed for agent development scenarios, it natively supports tool invocation, multi-step reasoning, and long-context tasks; it excels at code generation, automated workflows, and executing complex instructions; and it is deeply adapted to productivity tools such as Claude Code, OpenClaw, OpenCode, and Kilo Code.
Prices are per million tokens. Time to First Token and throughput are rolling averages measured on AIHubMix.
Promotional prices show the discounted rate; see each model page for promotion windows.
Daily traffic served through AIHubMix — how demand for each model is trending.
Measured on real AIHubMix traffic, hourly buckets. Gaps mean no traffic in that hour.

Monthly = daily × 30. Discounted rates applied where a promotion is active.
Longcat 2.0: $3.10/M output tokens; Grok 4.5: $6.00/M. Use the cost calculator above to estimate your own workload.
Grok 4.5: 1.9s time to first token measured on AIHubMix; see the live performance charts above for how each model behaves across the day.
Longcat 2.0 at 38.5 tok/s and Grok 4.5 at 26.7 tok/s, measured as output throughput on AIHubMix — a separate metric from time to first token.
Grok 4.5 accepts text and image input and supports thinking, tool calling, function calling, structured outputs and long context; Longcat 2.0 accepts text input and supports thinking and tool calling.
Yes. AIHubMix serves every model on this page behind one OpenAI-compatible endpoint, so switching between them is a one-line change to the model field — no second account, key or SDK.
