  3. I finally plugged GPT-3 into @pastelapp to generate color palettes from text prompts, and it just does exactly what I hoped it might do.

    Finally trying Apple's Foundation Models for palette generation, side by side with what I generated with ChatGPT.

    The first image is the prompt "Planets of the Solar System" with Apple's on-device LLM, the second image is the same prompt using GPT-3.5 as of 2 years ago.

    It can certainly do what I need it to do; whether the results are any good is an open question. I think it's inoffensive, and harmless, at the very least, so maybe I can move forward with it

    As a proof of concept, it confirms that the Foundation Models can indeed be applied to any kind of silly little task, and it’s so easy to get structured, deterministic output from it using the new @-Generable macro. No JSON, no parsing, just perfectly formed structs as output

      Even though the concept works, the performance is a little worrying. It takes an M1 iPad Air about 30 seconds to generate a handful of color palettes — which are just some hex codes with a name, nothing complex. Streaming the results in one by one becomes a necessity with those kinds of processing times

        Enabling streaming, you can see that the Foundation Models API is slow — I would say alarmingly slow — on M1 hardware. I'm not even sure what kind of optimization I might be able to do to speed this up, as it's seemingly purely on the token generation side 🤔

        It's going to take more than a little care and attention before you start sprinkling this all over your apps, that's for sure. Good to know

          Initial bringup on macOS 26 for Pastel. There are some significant system-level performance regressions that I'm going to have to debug my way through — I've lost my 60fps window resizing, that's for sure 😐 Other than that, it was a modern app with a forward-thinking design language, and it fits Liquid Glass on iOS and macOS without much trouble

            Slowly iterating on the design language for Pastel and fixing all the weird little bugs the new SDK introduced. Only now is it functional again

              Not making a whole lot of forward progress with my apps right now, so I'm gonna get some lateral progress done. Pastel still has about 5,500 lines of Objective-C code remaining that is all ripe for translating to Swift via Xcode's new ChatGPT feature. It'll give me a chance to sanity-check some of my legacy code in the process

                  Still a long way to go, but here's a before/after on Pastel on macOS 26 as of the current build.

                  During development, you spend so much time looking at the new design that you kinda forget how it used to look

                    Pastel on iPad is going to look effectively indistinguishable from the Mac version by the time I'm finished updating it for Liquid Glass

                      With today's work out of the way, I think Pastel's iOS 26 update is done for Mac and for iPhone. The iPad build is blocked by my earlier radar, and I haven't figured out a mitigation strategy yet, but we're nearly there

                        I've started the TestFlight process for Pastel for iOS and macOS 26. There are some known issues on iOS, including a severe hang, but most things are in place now, and there are still slots available 😄

                        Using TestFlight is a great way to help developers test beta versions of their apps.

                                  Giving Pastel a v2.4.1 today on macOS to update everything that looked blurry on a non-Retina display, as it's been a long time since I've given it a pass and some system metrics have changed lately that need round()ing. It's real hard to tell the difference from a JPEG, but here's a before/after

                                    The next minor version of @pastelapp will support exporting color palettes to Pixelmator Pro (on the Mac, at least, as they don't support that on iOS)

                                    Update: now available!

                                        The next version of Pastel tackles a bunch of things, including revamped undo/redo support. I recently added pinch-zoom to the image importer, too. Paying attention to lots of little corners of the app that haven't seen love in a while — time for a polish pass now that Liquid Glass is no longer taking up all of my development time

                                          Venturing out into the Great Unknown, I have finally made the switch from single-purchase to subscriptions in @pastelapp, for new customers, after talking about it for years.

                                          I should have done it years ago, but the risk of the floor falling out from under me scared me off. Better late than never!

                                          I'm much better prepared to handle the initial financial shock today, and as I've migrated everything to StoreKit 2 I've been really impressed by how easy Apple has made it to implement subscriptions
