With React Native AI, we ship precompiled libraries for the most popular models. This setup is reduced to zero.
100
Mike @grabbou.com · 19/09/2025
What are prebuilds in this context? (Not React Native this time!) MLC needs its runtime and model libraries compiled before use. Until now, that meant extra manual steps before you could run a model locally.

With React Native AI, you can choose the right provider for your use case: - Apple provider → system models built into iOS - MLC provider → run any supported model locally

It's an interesting alternative: you can mix both providers, e.g. run Apple on-device first while your remote model downloads in the background. x.com/grabbou/sta...

Mike @grabbou.com · 17/09/2025
Unlike the Apple provider, the MLC provider doesn’t rely on system-wide models. It downloads weights for each model you use, which can take time.
100
Mike @grabbou.com · 17/09/2025
What is going on here? - MLC is an optimized runtime for running different models on iOS, Android, and desktop GPUs - We download the model weights onto the device - Finally, we load it into the engine and set up everything needed for inference

Thank you Dan for all your work on Bluesky and React Native! I enjoyed discussions on decentralization, I think you did make it much easier for all of us, and moved React Native even further! Excited for what's next for you, and enjoy your family time! I'll try to catch you next time I am in London!

bittersweet news: today is my last day at Bluesky. 💙 i’m very thankful to the team for letting me learn many new things on the job (including React Native). i’m wishing them luck in the improbable — but inevitable — task of making decentralized social media usable and competitive.

Microfrontends for mobile? It always felt like an R&D project—until now. With Re.Pack & Zephyr Cloud, you can actually deploy them today. On React Universe On Air, I spoke with Zack Chapple & @jbroma.dev about what makes this possible & how it changes mobile dev. 🎧 Listen here: hubs.li/Q034sJZt0

Might have more to do with the API pricing itself. I am not any other app (Threads in particular - I shut down my IG), so this won’t be too much useful

Our work in that field is tightly coupled with WebAssembly work that we're doing some groundwork behind the scenes to move this module forward.

Mike @grabbou.com · 20/12/2024
We've been very busy working on the I/O primitives and you can expect a complete revamp of them in January. Right now, you can use WebSockets (that is not going to change) and treat the rest as a playground of what's possible.

Really excited about this! Nitro Modules are awesome (more on that in my next post), and that's exactly what we need to build more modules with it!
