The GPT-5 Cheat Sheet: 13 Things to Know About OpenAI's Latest AI Leap

Key Points

1. GPT-5 is now available on ChatGPT and via its API, with Microsoft integrating it into its products immediately.

2. Free tier users get standard GPT-5 initially, then switch to 'GPT-5 mini' after quota depletion; Pro subscribers ($200/month) have unlimited access, while Plus subscribers ($20/month) get standard GPT-5.

3. GPT-5 is multimodal, capable of processing and generating different types of data, eliminating the need for separate models like Vision or Sora.

4. The model has a 256,000 token input context window (400,000 tokens total), allowing it to process roughly 200,000 words at once.

5. GPT-5 is 'significantly less deceptive' and makes 80% fewer factual errors than previous models, improving reliability for enterprise applications.

6. Pricing for API users: GPT-5 costs $1.25 per million input tokens and $10.00 per million output tokens; GPT-5 mini and nano are cheaper alternatives.

7. GPT-5 does not yet generate videos (Sora remains separate) and is not AGI, but OpenAI emphasizes its advanced reasoning capabilities.

8. The model offers better persistent memory and personalization, allowing users to set long-term objectives.

9. OpenAI may hand over user data to governments if legally required, raising privacy considerations.

10. GPT-5 is designed to replace previous specialized models, though users can still choose between GPT-5, GPT-5 mini, and GPT-5 nano based on needs.
