Overview

GPT-3.5 Turbo is OpenAI's fastest model. It can understand and generate natural language or code, and is optimized for chat and traditional completion tasks. Training data up to Sep 2021.

History

GPT-3.5 Turbo (older v0613) became available via the OpenAI API on 2024-01-25.

Training & availability

Training data has a knowledge cutoff of 2021-09-30 — information about events after that date is unlikely to appear in the model's responses. OpenAI has not released the underlying model weights — access is via their hosted API only.

Capabilities

Context window: 4K tokens.
Input modalities: text.

Limitations

The knowledge cutoff is 55 months old — this model will not know about recent events, releases, or API changes.
The context window (4K tokens) is modest by 2026 standards — unsuitable for processing long documents in a single request.
Text-only — cannot process images, audio, or video inputs.

Pricing

Input: $1.0000 per 1M tokens
Output: $2.0000 per 1M tokens

Quick start

Minimal example using the openai API. Copy, paste, replace the key.

from openai import OpenAI

client = OpenAI(api_key="sk-...")
resp = client.chat.completions.create(
    model="gpt-3-5-turbo-0613",
    messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
)
print(resp.choices[0].message.content)
