Notes from the official page: Batch API is 50% off; US-only inference (inference_geo=us) is 1.1×; Claude 4.7+ uses a tokenizer producing ~30% more tokens for the same text. OpenAI, Google and xAI prices will be added after verifying their official API pages (OpenAI's page returned business-plan info, not API rates, on our check).
