Deep dive
On shared benchmark coverage, Google-Proof Q&A has Claude Mythos Preview at 94.6 and MiniMax M2.7 at 87.4, with Claude Mythos Preview ahead by 7.2 points. The largest visible gap is 7.2 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: Claude Mythos Preview, multimodal input: Claude Mythos Preview, and code execution: Claude Mythos Preview. Both models share reasoning mode, function calling, tool use, and structured outputs, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Mythos Preview lists $25/1M input and $125/1M output tokens, while MiniMax M2.7 lists $0.3/1M input and $1.2/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts MiniMax M2.7 lower by about $54.43 per million blended tokens. Availability is 2 providers versus 2, so concentration risk also matters.
Choose Claude Mythos Preview when coding workflow support and larger context windows are central to the workload. Choose MiniMax M2.7 when provider fit and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
