MiniMax M3 pricing for code refactoring

Quick start

Call MiniMax M3 with the OpenAI Python SDK pointed at api.minimax.chat:

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.minimax.chat/v1",
    api_key=os.environ["MINIMAX_API_KEY"],
)
response = client.chat.completions.create(
    model="minimax-m3",
    max_tokens=4000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.006000 per call at standard rates
# Input:  $0.30/MTok
# Output: $1.20/MTok

How MiniMax M3 compares on cost

Per-call cost for all models scoring 50+ on code refactoring benchmarks. Hover for details.

Highest-quality affordable option: Claude Haiku 4.5 at $0.0240/call (4.0x the cost, 72/100 quality). MiniMax M3 is already the cheapest choice for code refactoring.

What drives code refactoring cost

Refactoring sends existing code and gets a rewritten version back, so input and output are roughly symmetric, unusual for a code task. That symmetry means neither rate dominates and total cost tracks the size of the file. The practical lever is scope: refactoring one module per call rather than a whole package keeps you off the long-context pricing tier, where some providers re-rate the entire request.

For MiniMax M3 specifically, that means output tokens cost 4.0x more than input, at $1.20 vs $0.30 per MTok. At this use case’s 4,000/4,000 token split, output accounts for 80% of the $0.006000 per-call cost.
