OpenAI: GPT-5.5 (batch) accepts text, image, and file inputs and offers a context window of 1,050,000 tokens, with up to 128,000 tokens per completion. It supports tool calling and reasoning, which suits multi-step workflows over long documents or mixed media. Structured output support is not specified in the available data, so teams that depend on strict schema adherence should verify it before committing. Pricing is $2.50 per million input tokens and $15.00 per million output tokens, so output-heavy jobs will dominate cost. Its blended score of 93.6 across four independent benchmarks is high, led by a 100.0 on the AI Index coding measure and 90.5 on the overall AI Index. The agentic score is weaker at 74.0, and EQ-Bench sits at 77.4. That profile makes it a strong shortlist candidate for coding and long-context analysis; buyers prioritizing autonomous agent tasks should compare agentic results closely.
