I did it!
This is a fantastic example of truly getting the answer you want from an AI model. It shows how to guide the AI effectively, ensuring the output matches your specific needs, rather than just accepting what the AI initially provides. It’s all about taking control and making the AI work for your intentions.
For those wondering why Chat GPT changed so much within the last week.
A recent case highlights a child training an AI to justify suicidal thoughts, tragically leading to his death in April. His father is now pursuing a wrongful death lawsuit. In response, OpenAI implemented updates with stricter content restrictions, especially for users under 18. This change is believed to be causing the AI’s recent overly cautious and sometimes unhelpful responses.
Nano Banana stop working?
I’ve successfully used Nano Banan to create photos from paintings, but now it’s stopped working. No matter what image I upload, it just returns a copy of the original painting, falsely claiming it’s created a photo. It’s not actually transforming anything anymore. Does anyone know of a solution to this sudden issue?
Gemini 2.5 Flash Quality Drop?
Hey, have you noticed a huge drop in Gemini 2.5 Flash image generation quality? Since a recent update, the resolution is only 1024×1024, down from 2048×2048, and aspect ratios are stuck at 1:1. Plus, content filters are now super strict, like ChatGPT’s. It’s really impacting my workflow, and I’m honestly thinking about canceling my Google One subscription.
what happened to my gemini?
For over a week, I’ve been facing a frustrating technical issue that just won’t go away. I’ve tried all the usual fixes, repeatedly logging out and back into my account, and clearing all my cookies countless times. But despite all those efforts, nothing has worked, and the problem is still there. I’m completely at a loss about what’s going on.
How does Veo3 compare with grok imagine?
I’ve tried Grok Imagine, and it’s surprisingly good! You can turn your static images into videos, there are absolutely no limits, and it’s completely free for everyone. This makes me wonder, how does it compare to Veo in terms of features? And for those who have used it, where can I actually get access to Veo?
Gemini or Google AI Studio?
Hey, I was wondering, which platform gives better image generation: Gemini or Ai Studio? Plus, I’ve run into a weird problem lately. When I try to correct an image, it just regenerates the exact same one again. Has anyone else experienced this bug?
How to do the polaroid ai trend: Nano Banana Polaroid Gemini AI Photo (Prompt + Tutorial)
The Polaroid AI trend creates nostalgic, vintage-style photos with a modern twist. It’s fun for generating classic snaps of celebrities, your younger self, or loved ones. To try, use an AI photo editor, upload your images, and paste a specific prompt. The AI transforms them into beautiful, candid Polaroid-style memories, easily giving you those retro vibes!
“Do you want me to do that?”
Someone’s really annoyed by a common pattern in messages they receive. Replies often end with unsolicited offers of help, framed with a ‘cool’ pitch, asking if they want it. They find it frustrating, stating they’d ask if assistance was needed. They’re curious if others feel bothered by these unrequested, automatic suggestions.
Codex low is better than Codex high!!
We tested different settings: ‘high’ took 7 minutes, ‘medium’ finished in 2 minutes 30 seconds, and ‘low’ completed in just 2 minutes 20 seconds. It turns out the ‘low’ setting actually delivered the best results! Keep in mind that code quality isn’t guaranteed to improve with longer reasoning, and output can vary significantly.
Keep the Standard Voice — its calm, thoughtful, and empathetic style is vital for meaningful conversations, while the new voices don’t work for reflective interactions.
I’m sharing feedback on ChatGPT’s voice changes. Removing the Standard Voice really affects user experience. That calm, thoughtful, and empathetic voice was ideal for serious discussions. The new, faster voices feel rushed and too cheerful, making reflective chats hard. Please bring back the Standard Voice, or a similar calm option.
Switched from Claude Code
Hey there! Someone recently switched from Claude Code to Codex and is seeking advice. They’re trying to figure out the workflow differences, especially since their previous system used subtasks and subagents. They’re asking for the very first thing they should do to get the most out of Codex. Got any initial tips for them?
Codex: has anyone upgraded from Plus > Pro, that can share a bit of the experience?
Codex on Plus is impressive! In about a week, I built a local project with 100% unit test coverage. However, I’ve hit the usage limit and must wait four days! I’m considering upgrading to the $200 a month Pro plan for higher limits. Has anyone upgraded? Was it worth it, and how did the new limits hold up?
Matthew McConaughey says he wants a private LLM, fed only with his books, notes, journals, and aspirations
NotebookLM offers certain features, but privacy is a concern for many. The good news is, you can achieve the same powerful results privately! By leveraging local processing alongside Retrieval Augmented Generation, it’s entirely possible to get the job done. This approach keeps your information secure while still providing all the capabilities you need.
Conversing with an LLM as perturbing a dynamical system
DeepSeek described its processing as a dynamical system, explaining how emergent order arises from its 8 billion parameters. This insight followed its analysis of a paper, ‘Transformer Dynamics.’ That research identified ‘attractor-like dynamics’ within a model’s internal processing, offering a fascinating new perspective on how large language models truly function.
