Gotchas

Gotcha	Detail
SDK method	Python: client.chat.completions(...), JS: client.chat.completions({...}) — no .create() in either. OpenAI SDK uses .create() as usual.
JS constructor	new SarvamAIClient({ apiSubscriptionKey: "..." }) — NOT SarvamAI(). Key is passed explicitly.
content can be None	Models produce reasoning_content before content. If max_tokens is too low, reasoning consumes the budget and content is None. Omit max_tokens or set 500+. Check reasoning_content as fallback.
reasoning_effort	reasoning_effort="low"|"medium"|"high" for thinking mode. NOT thinking=True.
