Additionally, not all browsers and operating systems will have a built-in language model to expose, and not all devices will be able to run one. We are taking a variety of steps to attempt to mitigate these risks. For example, the specification is designed to allow the API to be backed by a cloud-based language model, which could help extend it to more users. And the high-level nature of the API, which hides the details of the specific language model, prompts, etc., makes it harder for developers to depend on specific outputs: they are getting generalizable data structure featuring three optional high-level proofreading functionalities, i.e. corrected text, error labeling and explanation in plain text format. Finally, the API surface is designed with many clear points of failure, that encourage the developer to probe for capabilities ahead of time and fall back to other techniques if a capability is not available. Nevertheless, interoperability and compatibility risk remains high for these sorts of APIs, and we'll be closely monitoring it during the prototyping period.Gecko: No signalWebKit: No signalWeb developers: Developers have expressed interest in our explainer and proposed more potential use cases for the API: https://github.com/webmachinelearning/proofreader-api/issues <https://github.com/webmachinelearning/proofreader-api/issues>Other signals:*WebView application risks *Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?None*Goals for experimentation *Although the feature has been behind-a-flag and instruction has been sent for Early Preview Program, we are interested in gathering more feedback from developers and several partners in testing out the API with real users. We're looking forward to getting feedback from such testing, especially with regards to output quality and latency, and what cases of proofreading are handled well vs. poorly. We also want to understand whether we've found the right shape of output to inform what corrections are made and if it's easy to use, and whether we've offered the right set of options (correction types and explanations) to control the output and if the resulting types and explanations reflect those controls to the extent that developers expect.*Ongoing technical constraints *None*Debuggability *It is possible that giving DevTools more insight into the nondeterministic states of the model, e.g. random seeds, could help with debugging. See related discussion at https://github.com/explainers-by-googlers/prompt-api/issues/9 <https://github.com/explainers-by-googlers/prompt-api/issues/9>.*Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? *NoNot all platforms will come with a language model. In particular, in the initial stages we are focusing on Windows, Mac, and Linux.*Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? *NoWe plan to expand the web platform test coverage of the API surface over the course of the origin trial.
