OpenAI will launch GPT-5.6, its most advanced AI model, on Thursday after a delay prompted by U.S. government concerns over the potential national security risks posed by increasingly powerful AI systems.
The release comes amid intensifying competition among AI developers who are racing to improve model performance, cut costs and expand capabilities for enterprise customers, fueling a wave of new systems and reasoning models across the industry.
Meanwhile, Chinese developers are reshaping the economics of AI by delivering increasingly capable models at a fraction of the cost.
Here's a look at some of the AI models on the market for consumers:
