Model Detail
OpenAI: GPT-5.5
—OpenAI: GPT-5.5 is a multimodal model released by OpenAI. And supports text+image+file->text inputs.
OpenAI: GPT-5.5 is priced at $5/M input tokens and $30/M output tokens. Operationally the model offers a 922K-token context window, which matters when sizing it for prompt-heavy or latency-sensitive workloads. This is frontier pricing, so cost-fit usually depends on whether the per-call quality justifies running a smaller commodity model two or three times to compare.
The published knowledge cutoff is 2025-12-01, so newer events will not be reflected in zero-shot answers without retrieval.
OpenAI: GPT-5.5 is best fit for mixed text-and-image reasoning tasks such as document understanding, and long-context tasks such as full-codebase analysis or book-length summarization (922K tokens). It is a less obvious choice for cost-sensitive batch processing where a commodity-tier model could be retried cheaply. Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
Autonomous disproofs of the sum-product conjecture over $\mathbb R$ with GPT-5.5 Pro
arXiv:2607.20525v1 Announce Type: new Abstract: OpenAI's recent disproof of the Erd\H{o}s unit distance conjecture marked a milestone for AI in mathematics. It also inspired another breakthrough: a human disproof of the Erd\H{o}s--Szemer\'edi sum-product conjecture over $\mathbb R$. In this paper, w
