When to Choose Google AI Studio vs OpenAI API
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Prompt testing iterates escalation logic with actual customer messages before going live. The 2M context window holds full ticket histories and knowledge bases in one API call.
Multimodal input ingests PDFs and images; Function calling outputs JSON directly into accounting software. System instructions lock the extraction schema across all documents.
speech-to-text API transcribes inbound calls; LLM categorizes urgency and routes tickets in a single API call. Batch API handles off-peak volume spikes without extra infrastructure.
The Embeddings API indexes internal knowledge bases weekly. A team chat bot queries semantically at $0.02 per 1,000 embeddings - no infrastructure rebuild needed.
