Model Detail

OpenAI: GPT-5.1 Chat is a multimodal model released by OpenAI. And supports text+image+file->text inputs.

OpenAI: GPT-5.1 Chat reports a Chatbot Arena ELO of 1,439 across 43,391 votes. On task-specific evaluations the model scores 66.0% resolved on SWE-Bench.

OpenAI: GPT-5.1 Chat is priced at $1.25/M input tokens and $10/M output tokens. Operationally the model offers a 272K-token context window, which matters when sizing it for prompt-heavy or latency-sensitive workloads. Pricing in this range is the working middle of the API market — neither the cheapest nor the most expensive option per token, so cost-fit is usually a function of how much output you generate.

OpenAI: GPT-5.1 Chat is published on Hugging Face but our pipeline has not yet captured architecture, license, or parameter-count metadata for this entry. The data is refreshed daily, so these fields typically populate within 24–48 hours of release.

OpenAI: GPT-5.1 Chat 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 (272K tokens). 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.
