I couldn't keep track of all the local AI tools flying around anymore. New engines, harnesses, tooling, benchmarks... every week. So I started awesome-local-ai: a list sorted by what you want to do, not by hype. The twist: it's built for agents too. Point your coding agent at it and ask it to recommend a setup for your hardware. It's early and DGX Spark-heavy. Help me fill the gaps: github.com/SeraphimSerapis/a…

Loved hearing about Sovereign AI at GTC Berlin. Throughout the sessions, the keynote, and conversations at the @GoogleCloudTech booth it was crystal clear that this topic is top of mind for people across the industry

Another cool setup I’ve seen at @NVIDIAAI GTC Berlin. This one by ABA Technology was very much about deploying a cohesive unit powered by the DGX Spark FEs

Met the one and only @christopherowen and GTC Berlin. Great chat about agents, models, inference, benchmarks, evals, and more. We could’ve probably spent the whole afternoon given how much there is to talk about in this ecosystem. Thanks for stopping by, Christopher!

If I say “DGX Station“ three times @digitalix might appear at GTC Berlin 😁

Found my kind of place at @NVIDIAAI GTC Berlin. Including the (for now) proof-of-concept switch. I counted 2 pairs of 5 ports - so you’d be able to pair up to 10 DGX Spark systems with breakout cables.

So cool. Blazing fast @vllm_project and @sgl_project deployments coming your way!
Native PyTorch on TPUs is here—and TorchTPU is officially open source. Train and serve models using the tools you already know: @vllm_project, @sgl_project, @_llm_d_, TorchTitan, @huggingface, and @raydistributed. Learn more from #PyTorchConf2026 → goo.gle/4hWxEVH

Gemini 4 Carbon checkpoint in Arena vs. Argon vs. GPT-6 Astra >Carbon is already better than Argon >GPT-6 Astra is starting to look outdated.

Had a blast at @NVIDIAAI GTC today in Berlin. I spent a good chunk of the day at the @GoogleCloudTech Hub just across the street of Station F to meet builders from across the region and will be at the conference for most of tomorrow, too!

Running LiteLLM? Check which version you run asap.
❗️LiteLLM was compromised (Again). The latest version 1.107.0 contains an infostealer and RAT. All 7 compiled wheels are backdoored. Anyone who ran pip install litellm==1.107.0 on any platform should assume credentials are compromised. More details soon!

OpenAI models are coming to Google Cloud, next to Gemini and Claude in Model Garden 🚀 If you pay for Google AI Pro or Ultra, your plan includes monthly Google Cloud credits. You'll be able to spend them on these models, too. What a great time to be a builder with @GoogleCloudTech 🔥 openai.com/index/openai-mode…

Attending @nvidia GTC in Berlin this week? Find me at the @googlecloud Space at w3.hub right next to the Technikmuseum. I'll be there to throughout the keynote and we have a full day of exciting content ahead of us. PS: We have probably some of the nicest coffee at GTC ☕️

I’m very proud of the team and the countless hours that went into carefully selecting these startups for the program! So much cool AI innovation is coming out of Sub-Saharan Africa, so this one is a cohort to follow closely.
🇿🇦 Meet the 15 startups joining the 2026 Google for Startups Accelerator: South Africa cohort. They’re building what’s next for South African innovation, backed by mentorship from experts at @Google, specialized AI infrastructure, global networks and R15M in equity-free funding. Meet the cohort: goo.gle/4BjPEkA
