Description

For the same model in different providers some properties are inconsistent at times.

Some examples for Openai's model gpt-5.1:

models.dev/providers/302ai/models/gpt-5.1.toml -> release_date = "2025-11-14"
models.dev/providers/abacus/models/gpt-5.1.toml -> release_date = "2025-11-13"
models.dev/providers/aihubmix/models/gpt-5.1.toml -> release_date = "2025-11-15"
models.dev/providers/jiekou/models/gpt-5.1.toml -> release_date = "2026-02"

There are some properties that must be identical across providers.
Including but not limited to:

  • release_date
  • update_date
  • knowledge
  • reasoning
  • open_weights
  • family

Review how provider model records are maintained, then verify that properties required to be identical match across providers for the same model.
