Use case	Better pick	Why
Budget-constrained production	N/A	The standard workload estimate is unavailable because one or both models are missing numeric input or output prices.
High-volume input processing	Tie	Lower prompt-token price matters most when prompts, retrieved passages, or documents dominate the bill.
Long responses and chatbots	Tie	Lower output-token price matters most when assistants generate many completion tokens.
RAG or long-document work	Kimi K2.6	A larger context window leaves more room for retrieved passages, conversation history, or source files.
