When this model fits

Practical guidance. Keep this model in a comparison when an existing application already uses its reasoning behavior. Evaluate the final answer and the sequence of tool calls separately. For a long case file, ask for the exact passages behind each conclusion and distinguish missing evidence from a negative finding. Compare with S5 using the same documents and tools so changes in the surrounding workflow do not obscure model differences.
