Some Notes: The released benchmarks for GPT 5.5 showed marginal gains; if anything I thought GPT 5.5 might have been of an improvement on OpenAI's end than the consumer end (providing the same level of outputs with much less thinking tokens and compute power), but after benchmarking them here, I was pretty impressed.
