GPT-5 for Developers: API Changes, Pricing, Model Router & Security

GPT-5: New API Features, Pricing & Security Explained: In-depth exploration of everything you need to know about GPT-5, focusing on the technical changes, new API features, pricing models, and advanced security implementations that go beyond the official launch presentation. ## Links - Code from the video: https://colab.research.google.com/gist/alejandro-ao/e852d7728ecca3bdfcf8020caefe6a7f/gpt-5.ipynb - 🚀 Complete AI Engineer Bootcamp: aibootcamp.dev - ❤️ Buy me a coffee... or a beer (thanks): https://link.alejandro-ao.com/l83gNq - 💬 Join the Discord Help Server: https://link.alejandro-ao.com/HrFKZn - ✉️ Get the news from the channel and AI Engineering: https://link.alejandro-ao.com/AIIguB ## References - Announcement: https://openai.com/index/introducing-gpt-5/ - Sam Altman's Tweet (1):https://x.com/sama/status/1953893841381273969 - Sam Altman's Tweet (2): https://x.com/sama/status/1953953990372471148 - GPT-4o vs GPT-5 Blindtest: https://gptblindvoting.vercel.app/ - CoT Monitoring for Misalignment: https://openai.com/index/chain-of-thought-monitoring/ - Jerry Liu's Tweet on pricing: https://x.com/jerryjliu0/status/1953582723672814054 - Reasoning Models Specs: https://platform.openai.com/docs/guides/reasoning?example=research#reasoning-summaries ## Topics We walk through what makes GPT-5 unique as a system of models, the updated API parameters, the shift to a model-router paradigm, detailed discussions on the new "reasoning tokens", and transparency issues around pricing and model selection. The demo includes practical coding examples using the updated OpenAI API, explains the critical new verbosity and reasoning effort parameters, and educates viewers about important changes regarding the Stateful Responses API and its implications for developers. The video closes with a review of OpenAI’s new, multi-layered security architecture, including real-time monitoring of model outputs and the significance of prompt hierarchy for safer application development. - Wha
