Model Detail

OpenAI: GPT-5.6 Sol is a multimodal model released by OpenAI. And supports text+image+file->text inputs.

OpenAI: GPT-5.6 Sol is priced at $4/M input tokens and $20/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 2026-02-16, so newer events will not be reflected in zero-shot answers without retrieval.

OpenAI: GPT-5.6 Sol 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.
