Because the SERHANT. S.MPLE team was not spending its time rebuilding infrastructure or maintaining one-off AI integrations, they could shift their attention to testing models against real product tasks and choosing the right tool for each job: Claude Sonnet for complex, accuracy-critical analysis like comparative market analysis, where strong structured-data reasoning matters Claude Haiku for lightweight intent and field-filling tasks where speed matters OpenAI models for conversational voice and general chat behaviors Gemini for image generation, browser automation, and computer-use workflows where reliability and speed are the priority
