Which should you pick?

On a typical workload, MiniMax M2.5 costs $189/mo against Claude Haiku 4.5's $800/mo — roughly 4.2× 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, MiniMax M2.5 has the larger 205K-token window (~307 pages). Only Claude Haiku 4.5 accepts image input — decisive if your prompts include images. By technical class (size and context, not measured capability), MiniMax M2.5 is the larger class (Mid) and the cheaper of the two — on spec, the stronger pick here.

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 Claude Haiku 4.5 or MiniMax M2.5 cheaper?

For a typical workload (1,500 input + 500 output tokens × 200,000 requests/month), MiniMax M2.5 costs $189/mo versus $800/mo for Claude Haiku 4.5 — about 4.2× 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 Claude Haiku 4.5 and MiniMax M2.5?

On price, Claude Haiku 4.5 is $1.00/$5.00 per 1M (in/out) and MiniMax M2.5 is $0.27/$1.08. By technical class (size & context) it's Mini (Claude Haiku 4.5) versus Mid (MiniMax M2.5). MiniMax M2.5 has the larger context window at 205K tokens. Only Claude Haiku 4.5 accepts image input.

Why is MiniMax M2.5 so much cheaper than Claude Haiku 4.5?

MiniMax M2.5 has a much lower per-token rate — $1.08/1M output versus $5.00, and it's a smaller technical class (Mid vs Mini). 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.
