--- title: "GPT-3.5 Turbo AI model: facts and benchmarks | Kendr" canonical: "https://kendr.org/models/openai-gpt-3-5-turbo" date_modified: "2026-08-12" profile_kind: "reference" --- # GPT-3.5 Turbo model profile GPT-3.5 Turbo is a OpenAI model profile with a 16,385-token context window. The dated catalog snapshot records text modalities and interfaces for structured output, text generation, tool calling. GPT-3.5 Turbo is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt. GPT-3.5 Turbo accepts text and returns text. The snapshot records structured output, text generation, and tool calling as capabilities or interfaces. The dated reference snapshot lists $0.5 input and $1.5 output per million tokens. The 2026-08-12 snapshot includes 1 Artificial Analysis index. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable. No comparable popularity rank or traffic share is present in the 2026-08-12 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated. Profile data was reviewed for the 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated. ## Profile facts - **Profile type:** Model research profile - **Provider or publisher:** OpenAI - **Context window:** 16,385 tokens - **Snapshot date:** 2026-08-12 - **Reference catalog ID:** openai/gpt-3.5-turbo ## Context, modalities, and identity GPT-3.5 Turbo accepts text and returns text.
