BES normalizes admitted public benchmark evidence for measured Index rows. Its legacy score and observables prior do not define the public language rank.
These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

GPT-4 Turbo holds ModelCap Index position #168 of 248 ranked language models as of 22 September 2026, with an Index score of 28.8 (interval 23.8–33.8); evidence: measured. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.
GPT-4 Turbo is listed at $10.00 per 1M input tokens and $30.00 per 1M output tokens as of 22 September 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $35.00 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
GPT-4 Turbo has a published context window of 128K tokens (128,000) and a maximum output of 4K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.
