Reviewed model profile

What to know

Grok 4.5 is included in Spring Prompt's first current-model profile cohort. The linked provider page verifies the canonical family identity; it is not treated as benchmark evidence.

The current release records 1 calculated, 3 insufficient-evidence and 0 withheld results across 4 capability and task scopes. An insufficient-evidence result is not a zero score.

Scores on this profile come only from reviewed, source-exact configurations in the public catalogue. Missing coverage is not inferred from provider claims or neighbouring model families.
