<https://github.com/webmachinelearning/meetings/blob/main/telcons/2022-03-09-cg-agenda.md#%E2%84%B9%EF%B8%8F-versioning>ℹ️ Versioning

  *   How to version the API? (supported ops and formats)

<https://github.com/webmachinelearning/meetings/blob/main/telcons/2022-03-09-cg-agenda.md#%E2%84%B9%EF%B8%8F-streaming-inputs>ℹ️ Streaming inputs

  *   Dedicated interface for streaming inputs (e.g. buffered inputs for video, audio)?

<https://github.com/webmachinelearning/meetings/blob/main/telcons/2022-03-09-cg-agenda.md#%E2%84%B9%EF%B8%8F-model-format>ℹ️ Model format

  *   Prototype vs standard format requirements
  *   "The Model Loader API needs a standard format supported across browsers and devices for broad interoperability." condition for standards adoption into WebML WG

<https://github.com/webmachinelearning/meetings/blob/main/telcons/2022-03-09-cg-agenda.md#%E2%84%B9%EF%B8%8F-support-for-non-ietf-754-float-point-types>ℹ️ Support for non-IETF 754 float point types

  *    issue: Open question: support for non-IETF 754 float point types #23 https://github.com/webmachinelearning/model-loader/issues/23


Some accelerators use non-standard float point types (e.g. bfloat16 and TF32) for performance, memory usage optimization. Discuss Model Loader experimentation with these types, open questions:

  *   Could WebNN and Model Loader API use a common approach for these types?
  *   How to represent, manipulate these types in JavaScript? Or auto-convert at runtime with some heuristic?
  *   How to have the two specs complement each other?
  *   WebNN provides general purpose feature that runs everywhere (write once, run everywhere), Model Loader optionally makes use of accelerator specific features, and could run extremely efficiently based on the model?
  *   How much information would this give away, privacy risk?
