GPT-4 Turbo

GPT-4 Turbo is OpenAI's enhanced variant of GPT-4 released in November 2023 at OpenAI's DevDay, bringing several improvements over the original GPT-4: a 128K context window (up from 32K), improved instruction-following, better cost (50-66% lower input pricing than GPT-4), and updated knowledge cutoffs. The model became the default GPT-4 offering in ChatGPT Plus and a popular choice for production API workloads through 2024 before being largely replaced by GPT-4o. GPT-4 Turbo supports vision (with the gpt-4-turbo-vision variant), function calling, and JSON mode. The model was tuned for better performance on coding and instruction-following tasks compared to original GPT-4. Pricing at roughly $10 per million input tokens and $30 per million output tokens made it more accessible than GPT-4 while remaining a premium option. AI governance, AI compliance, and AI risk management programs track GPT-4 Turbo as a legacy production model in many enterprises — supporting responsible AI through clear version tracking across enterprise AI inventories.
