What's the benchmark of GPT 5.6 ( Max ) when compared to Claude-Fable-5 ( Max )

Hi @long sedge. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

The knowledge sources you provided don’t contain any benchmarks that directly compare GPT‑5.6 (Sol/Terra/Luna) to a model named Claude‑Fable‑5 (Max), and they also don’t mention a Claude model with that exact name.

What we do have:

  • GPT‑5.6 Sol is described as a frontier model that advances coding, scientific reasoning, long‑horizon planning, and cybersecurity, with strong results on internal/third‑party benchmarks like Terminal‑Bench 2.1, ExploitBench, and several SecureBio evaluations. [GPT‑5.6 forum post; GPT‑5.6 preview help article]

  • A support reply on the OpenAI community forum notes that GPT‑5.6 Sol “slightly outperform[s] Claude Mythos 5” on certain tasks while using far fewer output tokens on ExploitBench, but this is an informal summary, not a full benchmark table, and it refers to Claude Mythos 5, not Claude‑Fable‑5. [GPT‑5.6 forum answers]

There is no table or score-by-score comparison vs any “Claude‑Fable‑5 (Max)” model in the sources, so I can’t provide a rigorous benchmark comparison between those two specific models.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
