I looked to define a term that’s being thrown around — #AI-native developer — with the help of @guypo.com @lmarsden.bsky.social and Thoughtworks’ Mike Mason so you can prepare your software teams for the near future.

What’s your definition? Only on @thenewstack.io
What Is an AI Native Developer?
We explain what an AI native developer is, how the role will evolve, and why spec-driven AI development is driving this trend.

Deepseek are clever fuckers. I wrote this about how Deepseek is pushing decision makers in large financial institutions to seriously consider running their own models instead of calling out to Microsoft, Amazon & Google

MS Teams in the UK this morning is the most grim experience imaginable, tons of jitter and bandwidth seems fucked - like trying to do a video call over a highly contended LTE connection - my network connection is fine (per mtr) - is there an outage in some MS data center somewhere?

We shipped a lot over Christmas and I came here to release it:

- You can now drag'n'drop files directly into knowledge for Helix apps (rather than having to go via the filestore).

- Initial support for MCP (more on this coming soon!)
Release 1.4.12 - apps drag'n'drop filestore, initial MCP support · helixml/helix

Thank you to @dciangot.com for doing the heavy lifting getting HelixML GPU runners running on Slurm HPC infra to take advantage of hundreds of thousands of GPUs running on Slurm infrastructure and transform them into multi-tenant GenAI systems!

This is so awesome! Imagine being able to combine the worlds of cloud-native scalable web services for LLMOps with the raw power of Slurm-powered supercomputers with some of the biggest compute power, networking and GPUs! Check out the writeup here: blog.helix.ml/p/running-ge...

Test Driven Development (TDD) for your LLMs? Yes please, more of that please!

Back to basics - write a test, see the test fail, improve the prompt, see it pass, check it in - just like you would with any other code 😄

Luke, this post, including the video, was very helpful. I loved the conference talk. I took my graduate students through a somewhat similar exercise last week for their last lab of the semester. Well done. Thank you.

@llm360.bsky.social please consider adding me to the open source LLMs starter pack ☺️

So how can we _actually_ do AI on Kubernetes? Here's my humble proposal: LLM apps and tests as data (CRDs). Deeply integrated into the existing CI/CD pipeline e.g GitLab and Flux. Self hosted LLMs on GPUs if you want to. Runnable code: github.com/helixml/gena...
