Q1
A streamed response disconnects halfway through a request that can create invoices. What is the safest design?
A
Retry immediately with a new operation identifier and depend on the model to notice any invoice it may already have created
B
Execute when the partial stream first forms valid-looking JSON because syntactic completeness is enough to authorize the write
C
Buffer the text for display but trigger the invoice before receiving a final stop reason so the user experiences lower latency
D
Treat partial text as provisional and execute only a validated, idempotent action after a completed tool/result event
Q2
What does streaming primarily improve?
A
The factual accuracy of each token because the application can verify every fragment before the model generates the next one
B
Time to first visible output and perceived responsiveness
C
The model’s total computation budget because streamed requests automatically receive more inference steps than non-streamed requests
D
The final completion time in every workload because displaying an early token guarantees that the remaining generation also finishes sooner
