GPT-5.4 vs MiniMax M2.7

GPT-5.4 and MiniMax M2.7 come from different camps — OpenAI versus MiniMax — and they split most sharply on price and context. GPT-5.4 runs at $2.50/$15.00 per 1M tokens with a 256K window; MiniMax M2.7 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: Balanced performance and cost. The recommended model for most production workloads. Previous MiniMax generation. Still available for audio-focused applications. 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 M2.7 is the cheaper of the two (Save $2.20 per 1M input), which adds up fast once real traffic hits. Use the calculator below to model your own volume.

→If your workload involves long document reasoning or multi-step instruction following → GPT-5.4 performs better with its 256K context.

→If cost is your primary constraint → MiniMax M2.7 provides ~88% lower cost per 1M tokens.

→If you need function-calling AI agents → GPT-5.4 is the only option with tool use support.

On performance, GPT-5.4 leans into excellent performance and pairs it with 256K of context — enough for excellent performance and lower cost than 5.5. MiniMax M2.7 answers with previous m-series across 256K, which makes it the stronger fit when you need previous m-series and 256k context. The gap is real, but it's a question of fit rather than dominance.

Pricing is where they part ways. At $2.50/$15.00 versus $0.30/$1.18 per 1M tokens, MiniMax M2.7 is the clear budget pick. Run a typical workload of 1M requests/month at ~1K input / 500 output tokens and MiniMax M2.7 keeps roughly $9110.00/month in your pocket.

Our take: if cost efficiency drives the decision, MiniMax M2.7 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.

Since both GPT-5.4 and MiniMax M2.7 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

# Before: response = client.chat.completions.create(model="gpt-5.4", messages=[...])
# After:  response = client.chat.completions.create(model="minimax-m2.7", messages=[...])

import OpenAI from "openai";
const client = new OpenAI({apiKey: process.env.KEY, baseURL: "https://api.apiyihe.org/v1"});
// Before: model: "gpt-5.4"
// After:  model: "minimax-m2.7"
