"157 models. 30 providers. One command to find what runs on your hardware" by @axjns.dev github.com/AlexsJones/l...

Have main outline/"scaffolding" in place now for my Live Coding talk at @kotlinconf.com this year....really happy with how it's turning out.

Updated first of #KMP samples I have to use Swift export (given Flow support now available in recent Kotlin 2.4 dev builds). Key usage here is that data is exposed from shared code as a Kotlin StateFlow and observed in iOS app using Swift's for await. github.com/joreilly/chi...

Your builds and remixes have brought us to the finish line. 🏁 Because of your collective effort, the #GoogleIO dates are unlocked. Join us May 19-20, 2026. 🗓️ Register today → goo.gle/io2026reg-6

I started programming as a hobby in 1982 (using BASIC on a ZX81) and then professionally from 1990. Industry has of course seen several major transitions since then but probably none as big as what we're experiencing right now. Will be very interesting to see what future holds.

Best Local LLMs to Run On Every Apple Silicon Mac in 2026 apxml.com/posts/best-l...

Roses are red, Violets are blue, I put my heart in commonMain, So it runs where you do. 😀 #KMP

Anyone aware of any comparisons of Claude Code and Junie....with both using same LLM (e.g. Opus 4.6)?

Updated Koog agent in ClimateTrace KMP sample to use a sub agent (that wraps tool to get population data). Seems like this approach provides option to 1. Reduce context 2. Potentially use different LLM (maybe sub agent can work with simpler/cheaper one) github.com/joreilly/Cli...

Looks like the Junie AI coding agent now provides option to use Claude Opus 4.6

Instant Compose - "Start building your Compose app within a minute using any editor, share it on GitHub minutes later." emilflach.github.io/instant-comp...

I asked Junie to make use of more of the @climatetrace.org APIs available (at api.climatetrace.org/v6/swagger/i...) in the ClimateTraceKMP sample (github.com/joreilly/Cli...) and it added UI/requests etc to allow showing more detailed "asset" information....very interesting to see!

I asked Gemini about best way to to manage pricing of FormAI app (play.google.com/store/apps/d...) to ensure LLM token costs are covered. Nothing too unexpected but lots of good advice. Also recommended I should use @revenuecat.com ....probably time I tried that out anyway!

Great to see trends like this! This btw is Claude Desktop using an MCP Server (developed using Kotlin MCP SDK) that's part of the ClimateTrace #KMP/#CMP project (github.com/joreilly/Cli...)

Maybe I'm impatient but I still really like the speed of Gemini 3 Flash (used with Junie) for the type of relatively targeted code changes I've been making....happy for the most part with the changes it makes (and fine I think to make occasional follow up requests if needed).

Opus 4.6 now top of Kotlin-bench Leaderboard firebender.com/leaderboard

The pace of #AI innovation is undeniable, but the constant barrage of new models, agents etc, and associated social media posts is becoming exhausting. Feels like we're collectively drowning in the noise.

Wonder how many layers of clothes I should wear next week! 🥶

Caoimhín Kelleher has single-handedly done so much for the ability of British commentators to pronounce Irish names 😃🇮🇪

Koin now has a native Kotlin Compiler Plugin ✨ - Compile-time auto-wiring - DSL + Annotations - KMP & Compose Multiplatform ready - No KSP needed Same simplicity, compile-time power. #Kotlin #Koin #AndroidDev

Really looking forward to speaking at @kotlinconf.com in Munich this May!

Now have a Kotlin Koog AI agent running in a Minecraft mod (thanks to @csinco.com for suggestion!). The agent is using a Gemini LLM and is configured with set of local tools that wrap the Minecraft API.

I know I overpronate but cool to be able to get Gemini to confirm that (I had initially asked it what kind of video it needed for analysis). It then provided strengthening exercises designed to target the weaknesses identified in the video.

Building AI Agents in Kotlin – Part 5: Teaching Agents to Forget blog.jetbrains.com/ai/2026/01/b...

Sons have me hooked on Minecraft and thought I should try to create a mod for it. This one is written in Kotlin (generated using Junie/Gemini) and provides access to Gemini from within the game!

Finally got Openclaw up and running with local Ollama model (trying gpt-oss:20b for now). Looked like I needed Ollama 0.15.3 (released last night) to run "ollama launch openclaw" for example docs.ollama.com/integrations...

I asked Gemini what it thought about Moltbook 😀

Wow, pretty crazy! youtu.be/-fmNzXCp7zA?...

Close to where I entered this world....and why I've always had somewhat of an affinity with this bear 😀

Why, thank you clawdbot (or I guess moltbot now!) 😀. Have it setup now on *really* old mac mini I had here gathering dust (could only update to Monterey but seems fine so far). Interacting with it through WhatsApp.

Some software developers are very focussed on the code itself while others are more interested in the solutions that the code can create. I believe that the latter will be more successful in the AI era.

Ktor 3.4.0 includes nice capability for dynamically generating a Swagger frontend. Example here from the backend that's part of the PeopleInSpace #KMP sample (github.com/joreilly/Peo...)

Our 12 year old son has been setting up his own Minecraft server...along with some custom mods. He's run into several problems but each time he's asked Gemini and has got the answer he needed. This is their world!

A lot happened around setting up Compose Multiplatform previews recently, with changes like the original AndroidX annotation becoming multiplatform in 1.10. So here's a shiny new documentation page with all the guidance you need to set up previews: kotlinlang.org/docs/...

Here's our overview and links to our initial materials to help you with AGP 9.0 migrations of your Kotlin projects! blog.jetbrains.com/k... More to come later still, such as updates in the KMP wizard and in our samples.

Was updating ClimateTrace #KMP sample (github.com/joreilly/Cli...) to use latest version of the Koog AI agent framework which included several breaking changes.....very nice example I think of value of using something like Junie AI coding agent (as used here) to make the changes.

Kingfisher supercharges app development across its brands mindera.com/blog/kingfis... Nice example of #KMP being used for B&Q (and other brands). "Featuring over 1.2 million products, the app used 200,000 lines of KMP and Swift code, natively shared between iOS and Android"

And then there were 6! From i0S SwiftUI client in PeopleInSpace #KMP sample (github.com/joreilly/Peo...)

KMP WorkManager - Production-ready Kotlin Multiplatform library for scheduling and managing background tasks on Android and iOS with a unified API. github.com/brewkits/kmp... Haven't tried it yet but looks very interesting. Kudos as well for comprehensive docs provided.

Very cool to have Compose Hot Reload bundled now with Compose Multiplatform v1.10.0! Example here from BikeShare #KMP/#CMP sample (github.com/joreilly/Bik...)

Compose Multiplatform 1.10.0 is out! 🎉 What’s new: ✨ Common @​Preview annotation 🧭 Support for Navigation 3 on non-Android targets 🔥 Stable and bundled Compose Hot Reload Learn more: https://blog.jetbrains.com/kotlin/2026/01/compose-multiplatform-1-10-0/

How can sub-agents make your AI agent cheaper and better? In part 4 of our series, we experiment with a dedicated `find` sub-agent. By limiting context growth and using a faster, cheaper model, we explore how Koog enables smarter agent design without sacrificing performance. Read more: jb.gg/49mxzp
