Grok 4.3 vs MiniMax M2.5
Token pricing, context window and real monthly cost, side by side. MiniMax M2.5 is the cheaper of the two for a typical workload — about 4.6× less.
Positioned by published specs — size, context and modality — not measured performance; a smaller model can sometimes outperform a larger one on your task.
Grok 4.3 is one class larger (Flagship vs Mid). Lean to the cheaper MiniMax M2.5 unless your task is demanding enough to need the larger class.

Which should you pick?
On a typical workload, MiniMax M2.5 costs $135/mo against Grok 4.3's $625/mo — roughly 4.6× cheaper. But the ranking depends on your output-to-input ratio: output is the pricier direction for both, so an output-heavy job (code generation, long answers) widens the gap while an input-heavy one (summarization, retrieval) narrows it. If you need to fit more in a single prompt, Grok 4.3 has the larger 1M-token window (~1,500 pages). Only Grok 4.3 accepts image input — decisive if your prompts include images. By technical class (size and context, not measured capability), Grok 4.3 is a Flagship and MiniMax M2.5 a Mid — so the lower price partly reflects a smaller class, not just a discount.
These are list and routed market prices, not measured outcomes. Two models at the same rate can still cost different amounts to finish the same task, because verbose or reasoning-heavy models emit more tokens. That gap is exactly what measured cost-per-task captures. The technical-class read above is likewise spec-based — size, context and modality, not measured performance — so a smaller model can still outperform a larger one on your specific task.
Frequently asked questions
Is Grok 4.3 or MiniMax M2.5 cheaper?
For a typical workload (1,500 input + 500 output tokens × 200,000 requests/month), MiniMax M2.5 costs $135/mo versus $625/mo for Grok 4.3 — about 4.6× less. Because output is priced higher than input, the winner can flip if your workload writes much more or less than this; check your own numbers in the calculator.
What's the main difference between Grok 4.3 and MiniMax M2.5?
On price, Grok 4.3 is $1.25/$2.50 per 1M (in/out) and MiniMax M2.5 is $0.15/$0.90. By technical class (size & context) it's Flagship (Grok 4.3) versus Mid (MiniMax M2.5). Grok 4.3 has the larger context window at 1M tokens. Only Grok 4.3 accepts image input.
Why is MiniMax M2.5 so much cheaper than Grok 4.3?
MiniMax M2.5 has a much lower per-token rate — $0.90/1M output versus $2.50, and it's a smaller technical class (Mid vs Flagship). The headline rate isn't the whole story, though: a verbose model can cost more to finish a task than its rate implies — that's what measured cost-per-task captures.
Which handles longer prompts, Grok 4.3 or MiniMax M2.5?
Grok 4.3 — its 1M-token context window (~1,500 pages of text) is the larger of the two, by roughly 5×.
