Phi 4 vs MiniMax M2.1
MiniMax M2.1 leads Phi 4 on the Artificial Analysis Intelligence Index, 20.9 to 5.9, and Phi 4 costs 8.6x less per output token ($0.14 vs $1.20 per million). Updated October 21, 2026; 11 benchmarks have a result for both.
Phi 4 or MiniMax M2.1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Phi 4 for output tokens 8.6x cheaper ($0.14 vs $1.20 per million) and work measured by LiveCodeBench (Artificial Analysis run) or Terminal-Bench Hard (Artificial Analysis run), where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
Phi 4 costs less
Repository review
50K input + 3K output tokens
Phi 4 costs less
Agent loop
200K input + 10K output tokens
Phi 4 costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
