Verdict

Choose Grok 4.3 for cost-sensitive workloads — it is roughly 200.0× cheaper on input tokens. Choose MiniMax-01 when you need its broader capabilities or stronger benchmarks.

Choose MiniMax-01 for long documents (4.1M tokens context). Choose Grok 4.3 for shorter prompts where the smaller window keeps latency and cost down.

These models serve different use cases (Multimodal vs Text & Chat) — pick the one whose category matches your workload.

Pricing example

A typical chat workload of 100,000 input tokens plus 50,000 output tokens.

Grok 4.3
€0.0003

100K in × €0.0010 + 50K out × €0.0030

MiniMax-01
€0.0750

100K in × €0.200 + 50K out × €1.10

For this workload, Grok 4.3 is cheaper than MiniMax-01 by €0.0747 per request.

Switch in one line

Both models live behind Railwail's OpenAI-compatible endpoint. Replace the model string and you are done.

JavaScript / TypeScript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://railwail.com/v1",
});

// Before — using Grok 4.3
let r = await client.chat.completions.create({
  model: "grok-4.3",
  messages: [{ role: "user", content: "Hello" }],
});

// After — switched to MiniMax-01
r = await client.chat.completions.create({
  model: "MiniMax-Text-01",
  messages: [{ role: "user", content: "Hello" }],
});
Python
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["RAILWAIL_API_KEY"],
    base_url="https://railwail.com/v1",
)

# Before — using Grok 4.3

Frequently asked questions

Which is cheaper, Grok 4.3 or MiniMax-01?
Grok 4.3 is cheaper. On a 100K input + 50K output example, Grok 4.3 costs about €0.0003 versus €0.0750 for MiniMax-01 — a saving of €0.0747.
Which has more context, Grok 4.3 or MiniMax-01?
MiniMax-01 has the larger context window at 4.1M tokens, compared to 1.0M tokens for Grok 4.3.
Is Grok 4.3 better than MiniMax-01 for coding?
For coding-heavy workloads we lean toward MiniMax-01 on this comparison — it scores higher on the relevant heuristics (category, tags, or context window). Both models are usable for code via Railwail's OpenAI-compatible endpoint, so the safest path is to A/B test on your own prompts.
Can I use both Grok 4.3 and MiniMax-01 via Railwail?
Yes. Both Grok 4.3 and MiniMax-01 are accessible through a single Railwail API key and the OpenAI-compatible /v1/chat/completions endpoint. You only change the "model" parameter to switch between them — no SDK swap, no separate billing.
How do I switch from Grok 4.3 to MiniMax-01?
Replace the model identifier "grok-4.3" with "MiniMax-Text-01" in your request payload. Everything else — API key, base URL, request shape — stays the same. See the code example on this page for the exact one-line change.
