I'm sorry, but the knowledge sources provided do not contain any information about "GPT-5" or "GPT-5 Low," nor do they reference LiveBench scores or rankings for these models. The available sources cover models such as GPT-4.1, GPT-4o, o3, o4-mini, and related variants, but there is no mention of GPT-5 or its performance on LiveBench or any other benchmark. If you need information about currently available OpenAI models and their benchmark results, I can help with that, but I cannot provide details on GPT-5 or its LiveBench scores as they are not present in the knowledge sources.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
