Claude Fable 5.1 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 $10/M — 33.3× 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 $50/M — 41.7× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- MiniMax M3 publishes weights (Open-weight (HuggingFace)); Claude Fable 5.1 is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Claude Fable 5.1 shipped 92 days after MiniMax M3 (2026-09-01 vs 2026-06-01).
