Overview
o4-mini and MiniMax M3 come from different camps — OpenAI versus MiniMax — and they split most sharply on price and context. o4-mini runs at $1.10/$4.40 per 1M tokens with a 200K window; MiniMax M3 sits at $0.30/$1.18 with 256K of context. Neither is objectively "better" — the right pick depends on what you're shipping.
In practice: Faster, cheaper reasoning model. Best for everyday math, coding, and logic tasks. MiniMax's latest model. 256K context window with strong multilingual and audio capabilities. Both ship through AI API Hub on an OpenAI-compatible endpoint, so you can move between them by changing a single model name — and settle the bill with USDT or USDC, no credit card required.
On cost alone, MiniMax M3 is the cheaper of the two (Save $0.80 per 1M input), which adds up fast once real traffic hits. Use the calculator below to model your own volume.

Performance & Pricing Analysis
On performance, o4-mini leans into fast reasoning and pairs it with 200K of context — enough for fast reasoning and cost-effective. MiniMax M3 answers with latest minimax across 256K, which makes it the stronger fit when you need latest minimax and 256k context. The gap is real, but it's a question of fit rather than dominance.
Pricing is where they part ways. At $1.10/$4.40 versus $0.30/$1.18 per 1M tokens, MiniMax M3 is the clear budget pick. Run a typical workload of 1M requests/month at ~1K input / 500 output tokens and MiniMax M3 keeps roughly $2410.00/month in your pocket.
Our take: if cost efficiency drives the decision, MiniMax M3 wins. Either way, both run through AI API Hub with USDT/USDC payments and instant activation — start with $5 and one API key covers every model.
How to Switch Between Models
Since both o4-mini and MiniMax M3 are available through AI API Hub with OpenAI-compatible API format, switching between them requires only changing the model name parameter. Your existing SDK code works without modification.
from openai import OpenAI client = OpenAI(api_key="YOUR_KEY", base_url="https://api.apiyihe.org/v1") # Before: response = client.chat.completions.create(model="o4-mini", messages=[...]) # After: response = client.chat.completions.create(model="minimax-m3", messages=[...])
import OpenAI from "openai";
const client = new OpenAI({apiKey: process.env.KEY, baseURL: "https://api.apiyihe.org/v1"});
// Before: model: "o4-mini"
// After: model: "minimax-m3"curl https://api.apiyihe.org/v1/chat/completions \
-H "Authorization: Bearer YOUR_KEY" \
-d '{"model": "minimax-m3", "messages": [{"role":"user","content":"Hello"}]}'💡 AI API Hub supports both models through one API key. No separate accounts needed. Pay with USDT/USDC for all models.
Frequently Asked Questions
What is the difference between o4-mini and MiniMax M3?
They come from different providers and optimize for different things. o4-mini is OpenAI's reasoning model — 200K context, $1.10/1M input. MiniMax M3 is MiniMax's minimax model — 256K context, $0.30/1M input. The short version: pick based on context size, price, and which capabilities your app actually needs.
Which model is cheaper?
MiniMax M3 is cheaper at $0.30/1M input. At typical volumes that difference compounds — run the cost calculator above with your real request count to see the monthly gap.
Which model is better for coding?
Neither is a dedicated coding model. Check the features table above to see what each actually supports.
Which model has a larger context window?
MiniMax M3 wins on context — 256K versus 200K. That matters for long documents, large codebases, or multi-turn conversations that need to stay coherent.
Which model is faster?
MiniMax M3 generally responds faster — lighter models tend to have lower latency, though o4-mini may pull ahead on complex reasoning where its larger capacity helps. For latency-critical apps, benchmark both at your real workload.
Which model should I choose?
It depends on your priority. If cost drives the decision, go with MiniMax M3 ($0.30/1M). If you need to process long documents or large contexts, MiniMax M3 and its 256K window is the safer bet. When in doubt, start with the cheaper model and upgrade only if quality demands it.
Can both models use function calling?
Not equally. MiniMax M3 supports function calling; o4-mini does not. If agents are central to your app, that narrows the choice.
How much does o4-mini cost?
o4-mini runs $1.10/1M input and $4.40/1M output, with 200K of context. It's pay-as-you-go with no minimum — through AI API Hub you can start with $5 and scale up.
How much does MiniMax M3 cost?
MiniMax M3 runs $0.30/1M input and $1.18/1M output, with 256K of context. It's pay-as-you-go with no minimum — through AI API Hub you can start with $5 and scale up.
Which model is better for enterprise use?
Neither is exclusively enterprise-tier. For heavy enterprise use, look at the flagship options in each provider's lineup.
Which model is better for AI agents?
Agent support differs — see the function-calling answer above.
How do I access these APIs?
Both run through AI API Hub on one OpenAI-compatible endpoint. Register at api.apiyihe.org, deposit USDT or USDC (no credit card), grab your API key, and call https://api.apiyihe.org/v1 with model name "o4-mini" or "minimax-m3". One key unlocks every model.
Can I switch between these models without changing my code?
Yes — because AI API Hub is OpenAI-compatible, moving from o4-mini to MiniMax M3 (or back) is just a model-name change. Your SDK setup, message format, and streaming logic stay exactly the same.
Final Verdict: Which Should You Buy?
💰 Cheapest pricing · ⚡ Instant API key · 🚫 No credit card · 💎 Pay with USDT/USDC · 🔌 OpenAI-compatible
Conclusion: MiniMax M3 is the cheaper choice — save $2410.00/month (73%) at your volume. Buy MiniMax M3 API for the cheapest pricing and instant API key.
