Not yet sourced — OpenAI GPT-4 Turbo: Power, Capacity, Dimensions, Weight, Warranty, Starting MSRP. OpenAI GPT-4o: Power, Capacity, Dimensions, Weight, Warranty, Starting MSRP. No manufacturer, official or retailer source we read publishes these yet; we don't estimate them.

Skip both if

Neither publishes power, capacity, dimensions, weight and 2 more decision fields yet.

OpenAI GPT-4 Turbo and OpenAI GPT-4o represent successive iterations in the same model family, each balancing capability against operational cost in distinct ways. Public benchmarks and API documentation show GPT-4 Turbo delivering strong reasoning. And output quality at a lower per-token rate, making it attractive for high-volume applications where every cent of inference expense matters. GPT-4o, released later, brings measurable gains in instruction following, multimodal handling, and response coherence according to independent evaluations, yet these improvements come at a higher price per token. Neither model has disclosed exact power consumption, context-window capacity in every usage tier, or additional operational metrics that developers often request for large-scale deployment planning. The short version: choose OpenAI GPT-4 Turbo when token cost is the deciding factor and OpenAI GPT-4o when the newest architecture justifies the added expense.

Verdict: GPT‑4o is the stronger choice if you need image or audio input alongside text, offering a clear feature advantage. GPT‑4 Turbo remains preferable for pure text workloads where cost and simplicity matter. Both are discontinued, so future updates are unlikely.

Provisional pick: OpenAI GPT-4o — not enough sourced decision facts for OpenAI GPT-4 Turbo and OpenAI GPT-4o. We don't rank on specs we can't verify.
