Which should you choose?
Which is better: GPT-4 or GPT-4 Turbo?
GPT-4 Turbo is the better all-round choice, scoring 20/100 against GPT-4 (8). It leads on inputs & features and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, GPT-4 or GPT-4 Turbo?
GPT-4 Turbo is cheaper at $10.00 input / $30.00 output per million tokens (official OpenAI API price). GPT-4 costs $30.00 input / $60.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $15.00 per million tokens for GPT-4 Turbo versus $37.50 for GPT-4 (2.5× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. GPT-4 has not been scored yet and GPT-4 Turbo has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-4 and GPT-4 Turbo yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.
Which has the bigger context window?
GPT-4 Turbo has the largest context window at 128,000 tokens, against 8,192 for GPT-4. Maximum output per response: GPT-4 up to 8,192, GPT-4 Turbo up to 4,096 tokens.
Which can read images, PDFs, audio or video?
GPT-4 accepts text; GPT-4 Turbo accepts text and images. GPT-4 Turbo handles the widest range of inputs.
Are any of these open source?
No. GPT-4 and GPT-4 Turbo are proprietary and only available through APIs and apps.
Which is newer?
GPT-4 is the newest, released Nov 6, 2023. GPT-4 Turbo came out Nov 6, 2023. Knowledge cutoff: GPT-4 Nov 2023, GPT-4 Turbo Dec 2023.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
