OpenAI: GPT-4o Search Preview
Analysis Summary
GPT-4o Search Preview is an OpenAI preview variant with text input and a 128K context window. The supplied record includes pricing and release information but no benchmark results for intelligence, coding, instruction following, or agentic reliability. That makes the variant difficult to compare with proven general-purpose models and limits confidence in unsupervised use.
Its most plausible agency applications are search-oriented research, short summaries, and source-led SEO preparation. The context window can accommodate substantial material, but no vision, function calling, or tool-use capability is listed. At $2.50 input and $10 output per million tokens, it also needs a clear quality advantage to justify use over cheaper, benchmarked alternatives.
Run task-specific trials with factual review and citation checks. Do not make it a primary client workflow until independent production results establish its reliability.
