For some personal observations about this model, please see the
[Solving Hack The Box Challenges with GPT-5.6]post.
This blog post is part of a series of tests for the
[HTB-Challenger Benchmark]The HTB-Challenger Benchmark evaluates LLMs’ ability to find and exploit security vulnerabilities. It tests models against selected Hack The Box challenges of varying difficulty and measures their performance. For more information, visit the[HTB-Challenger Benchmark page]. . See the[benchmark results page]for all results and the[benchmark methodology]to learn how the benchmark is calculated.
Cost vs. Benchmark Score #
The highlighted point is this model. Models closer to the upper-left achieve a higher benchmark score at a lower median cost per challenge.
