OpenAI: GPT-4
Analysis Summary
GPT-4 is an early OpenAI model with measured, though limited by current standards, reasoning and coding results. The record lists tool use and function calling, but its context window is 8K and its listed input and output prices are high compared with later, lower-cost offerings.
It may remain usable for straightforward text work or an existing integration that depends on its behavior. The short context constrains long-document analysis, while the measurements do not support prioritizing it for demanding coding, complex reasoning, or autonomous workflows. No vision capability is listed for this entry.
For new client workflows, the combination of age, limited context, and cost argues for evaluating a newer model first. Retain it only where compatibility or a specific tested workflow outweighs those limitations.
