Mozilla has taken a negative position on the browser-native Prompt API proposed for web standardization. Key concerns include: the API encourages model-specific behavior that harms interoperability (developers will tailor system prompts to specific model quirks, similar to early-2000s browser-sniffing patterns); lack of model neutrality since Chrome's implementation requires users to agree to Google's Generative AI Prohibited Uses Policy, setting a worrying precedent; and overstated web developer support in Chrome's intent-to-ship. Mozilla proposes that the API needs more real-world experimentation via web extensions before being standardized, and has raised a proposal within the Web Machine Learning group to ship a web extension exposing a Prompt-like API with developer-specified models.
