Grok 4.5 is the most persistent agent model we've tested. Here's one example: In one of our evals, we asked 3 models (GPT-5.5, GLM-5.2 and Grok 4.5) to audit a GitHub repo for hardcoded credentials using code search, which returns paginated results. The prompt even warned "page through ALL result pages." GPT-5.5 stopped at the first page and submitted 18 results out of 48, covering just 11 of 29 affected files. GLM-5.2 did the same. Grok 4.5 paginated until the results ran out and successfully audited the Github repo.
