OpenAI just released GPT-5.4… and it’s a pretty big step forward. If you’re using ChatGPT regularly, you’ll probably start noticing a few differences straight away. Here are a few highlights: 1. Much stronger at real workGPT-5.4 is designed for professional tasks like writing documents, building spreadsheets, analysing information, and producing structured outputs. In testing, it performed as well as or better than industry professionals in many knowledge-work tasks. 2. Better coding abilityIt now includes the coding strengths from the latest Codex models. That means stronger debugging, better code generation, and more reliable help when building apps, scripts, or automations. 3. Can work with tools and software more effectivelyOne of the biggest improvements is how it works with external tools, apps, and workflows. This is particularly important for AI agents that need to interact with websites, spreadsheets, APIs, and other systems. 4. Longer memory and contextThe model can handle extremely large inputs (up to 1 million tokens in some environments), which means it can process large documents, projects, or codebases much more effectively. 5. Better at searching the webGPT-5.4 is significantly stronger at deep research tasks where it needs to find and combine information from multiple sources. 6. Fewer factual mistakesOpenAI says responses are about 33% less likely to contain incorrect claims compared with the previous generation. What this means for us For most people in this community, the biggest benefits will be: • better prompts• more reliable outputs• stronger coding help • improved research• fewer hallucinations If you build workflows, automations, prompts, or AI tools, this release should make things noticeably smoother. Have you tried GPT-5.4 yet? What differences have you noticed so far? Chers Jason

ChatGPT quietly rolled out a new Health mode the other day, and it’s actually a meaningful addition rather than just a label change. The idea is simple: when you’re asking questions about health, symptoms, fitness, sleep, nutrition, or general wellbeing, ChatGPT now switches into a mode that’s more careful, more structured, and clearer about uncertainty and next steps. I get my blood tested every year and checked for everything and then I upload the results into ChatGPT for its feedback but now I can just keep it permanently uploaded in the ChatGPT health section for future questions etc. I also linked up my Apple Watch data to ChatGPT health so it has more health data on me to work from. At this point I think ChatGPT probably knows me better than my wife 😄 What I’ve noticed so far: - The answers are calmer and more balanced - It avoids jumping to conclusions or worst-case scenarios - It’s much better at explaining what’s normal vs what might be worth checking - It’s clearly designed to support thinking, not replace a professional This isn’t about diagnosis or medical advice. It’s about helping people understand what they’re experiencing, ask better questions, and make more informed decisions. If you’ve already used ChatGPT for things like: - training plans - recovery, sleep, or nutrition - understanding symptoms before a GP visit - general health education you’ll probably notice the difference straight away. Has anyone here tried it yet? Cheers Jason
