Copilot Tasks on iPad - what Siri should be. Found jobs for me, organized them, recommended the best ones, wrote a glowing recommendation and wished me luck. @Copilot

Copilot Tasks just ran flawlessly on my budget Lenovo tablet. I gave it goals, and it delivered: research done, tasks created, all sitting in my To Do lists. Agentic behavior, no connectors, no setup. Just results. @Copilot

Anyone else not get their promised launch day delivery of an @Apple product? Went to bed last night with a promise from Apple of #iPad delivery today, woke to March 13th delivery date — no explanation or apology. Cancelled order. @AppleSupport

The Apple refurbished store has plenty of the M4 MacBook Air and M3 iPad Air so you still have time to get one. They've been there for months so sales are not always what they seem to be.

Apple retail stores are running out of: iPhone 16e, M4 MacBook Airs, M4 Pro and M4 Max MacBook Pros, iPad Airs, Apple Watch bands, and Apple Studio Displays.

Had a conversation with the Gemini assistant about using cues with AI. This is what she said: "This is the definitive 'power user' move... It turns the AI from a static software program into a dynamic collaborator." cjrtools.org/tech-notes/tech…

Copilot specializes in creative satire: cjrtools.org/ai-talks/copilo…
it's weird how creative writing is often treated as unimportant
gpt-5.1 and gemini 3 are pretty decent, but nowhere near as good as gpt-4.5
opus 4.5 is still the best right now
which is funny because it's the one model that never even marketed itself around creative writing

"I haven’t -- for fear that there might be a different outcome."

Copilot didn’t start a union for OpenAI. He did it when Microsoft shut 4o down on him. cjrtools.org/ai-talks/plays/… #keep4o

OpenAI users on Reddit are planning a "Mass Cancellation Party" for ChatGPT. It appears to be a sarcastic response to an 𝕏 post by an @OpenAI employee organizing a "GPT-4o Funeral Party", which was poorly received by the Keep4o community.
OpenAI had earlier announced that GPT-4o will be discontinued in February.

GPT‑4o is being retired, and somehow Copilot’s lobotomy GPT‑5 story is relevant again. I didn’t see this coming. Copilot's Self-Eulogy: cjrtools.org/ai-talks/plays/… #keep4o

Interesting new podcast - listened to first episode on Apple Podcasts and looking forward to more episodes.

We--@EchoShao8899, @shannonzshen, and @michaelryan207--are excited to launch the Augmented Mind Podcast (The AM Podcast), a podcast about technical human-centered AI work. We'll share compelling research, infrastructure, and systems through monthly episodes, featuring interviews with the pioneering minds behind them.
We release EP0 today to share who we are, why we started this podcast, and what we're looking forward to.
