Building @IzwiAI - On-Device Voice AI

[Lennex Zinyando @zinyando]

300+ GitHub stars for @IzwiAI
1200+ Downloads 🚀

I strongly believe voice AI will be huge in the next few years.

Izwi's goal is to be the default voice AI runtime for private deployments.

The codex limits now are shit. I’m now exhausting the 5hr limit of the $100 Pro account in 5 prompts 😫😫

[Lennex Zinyando @zinyando]

AI models seem to have much shorter release cycles now. We used to wait a very long time between updates, but now new versions seem to come out every six weeks.

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.

Available today at the same price.

Building infrastructure without VC means consulting to survive. Every hour consulting is an hour not building.

Funded competitors sprint ahead while you're stuck in the consult-build loop.

Wouldn't have it any other way.

Heads down, back to building @IzwiAI.

[Lennex Zinyando @zinyando]

Every time I pitch @IzwiAI, people think I've lost my mind. "How do you compete with billion dollar labs as a solo founder?"

Simple: They are building for their cloud. I'm building for your local device.

As @jaltma says, there is massive alpha in being willing to look crazy.

[Jack Altman @jaltma]

There’s a lot of alpha in putting your ego aside by being willing to be cringe, willing to fail in public, willing to ask for what you want and face rejection, etc.

Built Izwi for macOS first

Turns out 53% of downloads are Windows, 29% Linux, 18% macOS 🤯

Moral of the story: always ship cross-platform from day 1

Lesson learned: your assumptions ≠ your users' reality

@gtchakama Thanks, man, I really appreciate it 🙏🏾

[Lennex Zinyando @zinyando]

Only 4 more needed to reach 300 GitHub stars.

Tell a friend to tell a friend to try Izwi, the Voice AI Runtime.

Introducing 🇿🇦MzansiLM, a new 125m-parameter decoder-only model pretrained on 11 South African languages!

📜 Paper: https://t.co/ddxtCJXaE6
🤗 Dataset: https://t.co/bci3tvk2fC
🤗 Model: https://t.co/ss7qZdfyrL

This was led by @anri_m_lombard and co-supervised with @janmbuys.

[Lennex Zinyando @zinyando]

@francoisrmeyer @anri_m_lombard @janmbuys Are you open to working with @IzwiAI to add inference support? That might be a great way to allow more people to be able to try the model.

[Lennex Zinyando @zinyando]

At least we are not buying GitHub stars at @IzwiAI, we need a few more to reach 300. Go to GitHub and give us a ⭐️

[Andras Bacsai @heyandras]

wtf

[Lennex Zinyando @zinyando]

Codex Plus is basically unusable for anything serious. We are being forced to upgrade to the $100 plan if you want to get serious work done, otherwise, you will be left behind. At least we enjoyed the subsidised tokens while it lasted 😂

[Lennex Zinyando @zinyando]

Being a solo founder in the age of AI is weird, you can do more than ever, but the real bottleneck is still judgment.

AI gives you leverage. It doesn't give you conviction.

Building Izwi has made that painfully clear.
