gemini-3.5-flash uses thinking tokens that share the same budget as output tokens. With maxOutputTokens=200 (vision) or 100 (intent), the model would exhaust the budget on thinking (~288-1043 tokens) and truncate the actual response to 8-11 tokens, producing garbage output like "040825". Fix: 2048 for vision (needs full JSON), 1024 for intent, 512 for connection test. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
