Hy4 preview vs MiniMax M3

What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Input price
- MiniMax M3 at $0.3/M against $0.834/M — 2.8× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- MiniMax M3 at $1.2/M against $2.501/M — 2.1× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — Hy4 preview under Apache-2.0, MiniMax M3 under Open-weight (HuggingFace). Check the licences rather than assuming they permit the same commercial use.
- Recency
- Hy4 preview shipped 88 days after MiniMax M3 (2026-08-28 vs 2026-06-01).
