After Months of Speculation, OpenAI Finally Launches GPT-5

Key Points

1. GPT-5 is a major upgrade over GPT-4, with enhanced reasoning, coding capabilities, and reduced hallucinations, positioning it as a step toward AGI.

2. The model features a 400K token context window, though it is smaller than competitors like Claude 3 and Gemini 1.5, which support over 1 million tokens.

3. OpenAI introduced tiered access: free users start with GPT-5 before switching to GPT-5 mini, while Pro subscribers get unlimited access to the full model.

4. GPT-5 achieved top performance on SWE-bench, making it the most powerful model for software engineering tasks currently available.

5. OpenAI's ChatGPT has 700 million weekly active users, competing with Meta AI, which also has 700 million users due to its integration with Instagram and WhatsApp.
