Overview
The latest GPT-4 Turbo model with vision capabilities. Vision requests can now use JSON mode and function calling. Training data: up to December 2023.
Our take
As an AI chatbot, OpenAI's GPT-4 Turbo distinguishes itself through its specific capabilities rather than broad affordability. While alternatives like Claude or Gemini offer similar core functions, this model's strengths lie in its structured output and vision capabilities. For instance, a developer needing to automate image analysis and integrate the results directly into a system could leverage its vision input combined with JSON mode and function calling. Unlike many current models, however, its 128,000-token context window is comparatively smaller, and its API pricing of $10 per 1M input tokens is above average. It is ideal for developers and researchers who require reliable, structured data extraction from images or text and are building agent-style workflows, provided their token usage is carefully managed. Those prioritising extensive context windows or lower API costs may find other options more suitable.
