What usually stops PyTorch training from scaling out to a cluster is the container, not the model code. Every container needs the same CUDA runtime, a PyTorch build compiled against it, NCCL (NVIDIA Collective Communications Library), the Elastic Fabric Adapter (EFA) userspace libraries, the AWS OFI NCCL plugin that connects NCCL to EFA, and a…

Using torchtitan on AWS Trainium means using it the way you always have. TorchNeuron registers Trainium as a native PyTorch device, which lets torchtitan use it through standard PyTorch interfaces. You can use these configurations to pre-train from random initialization or fine-tune published weights. You can also customize the model implementation and kernels for your…

At 35 years old, I’m under no illusion that I’m “old” (what even counts as “old” these days?), but I am aware that I’m dangerously close to the perimenopausal years and the inevitable battle that comes with maintaining strength, mobility, bone density, lean muscle and a healthy metabolism as I steamroll toward my 40s.

Every “best AI image generator” list eventually runs into the same wall: none of the big names, not Midjourney, not Flux 2, not Nano Banana Pro, can reliably draw your face, your dog, or your brand’s mascot without a nudge. That nudge is a LoRA. Training one used to require a research background and a…
