Use-Case Decision Matrix
| Use case | Better pick | Why |
|---|---|---|
| Budget-constrained production | Tie | Both models are estimated at $0.9 for the standard 1M input plus 500K output workload. |
| High-volume input processing | Perceptron Mk1 | Lower prompt-token price matters most when prompts, retrieved passages, or documents dominate the bill. |
| Long responses and chatbots | KAT-Coder-Pro V2 | Lower output-token price matters most when assistants generate many completion tokens. |
| RAG or long-document work | KAT-Coder-Pro V2 | A larger context window leaves more room for retrieved passages, conversation history, or source files. |
