OpenAI has released GPT-4 Turbo with Vision through its API, bringing numerous improvements to the upgraded model, including JSON mode and function calls for visual data processing. The model also promises performance enhancements and plans to integrate with the popular ChatGPT, providing users with an even better experience. What is GPT-4 Turbo? It is a powerful multimodal model that can handle both text and image inputs. Leveraging its vast knowledge base and exceptional reasoning capabilities, this model delivers precise outputs. It features a larger context window of 128k tokens (compared to GPT-3's 2048 tokens), allowing users to add over 300 pages of text in a single prompt, greatly enhancing flexibility and convenience. The true appeal of GPT-4 Turbo lies in its optimized performance. The price of input tokens has been reduced by three times, while the price of output tokens has been halved compared to previous models. This upgrade makes GPT-4 Turbo an efficient and cost-effective solution, resulting in substantial cost savings for users. However, GPT-4 Turbo is not the sole focus of OpenAI. The company has also teased its upcoming Voice Engine technology, which generates natural-sounding speech from text inputs and short audio samples (currently limited to 15 seconds). While this technology remains out of reach for the general public, its potential applications are highly anticipated. Furthermore, OpenAI has hinted at the arrival of its next large-scale model, GPT-5. It is claimed that GPT-5 will achieve "substantially better" performance. Interestingly, Microsoft inadvertently revealed the existence of GPT-5 Turbo in its Copilot Pro subscription, further fueling speculation and anticipation for OpenAI's future technological developments. Overall, OpenAI's release of GPT-4 Turbo with Vision once again showcases its innovative prowess and leadership in the field of artificial intelligence. We look forward to seeing more astonishing technological breakthroughs and application scenarios from OpenAI in the future.
