thinkingLevel z modelami Gemini 2.5 (lub thinkingBudget z modelami Gemini 3) może powodować błędy. Używaj właściwego parametru dla wersji swojego modelu.streamGenerateContent?alt=sse jako operatora, aby odbierać Server-Sent Events podczas generowania treści przez model. Każde zdarzenie SSE zawiera linię data: z obiektem JSON GenerateContentResponse.
