STR stretch + greenfield/terminal skill. Vendor launch table Terminal-Bench 2.1 83.3% — AA article places Grok 4.5 at/near frontier on TB (peer Fable 84.3%, GPT-5.5 83.4%, Opus 78.9%). Prefer AA harness row when float is re-scraped.
Caveats
Known limitations
- Vendor-reported; cannot receive confidence S.
- Harness may be Grok Build-class, not Terminus-2 — compare carefully to AA Terminus rows.
Weighting
