When a field evolves quickly, its vocabulary often evolves faster than its shared understanding. Terms start to blur, get reused in different contexts, or become shorthand for ideas that are never fully explained. We are currently seeing this happen in the field of AI Agents, where concepts are getting mixed together, some are renamed, and others are widely used for a few months before quietly disappearing. This can be overwhelming for newcomers, and even for practitioners trying to keep up […]

TL;DR, because you have models to train and we respect that: Async RL has a dirty secret: every step, the trainer has to ship the whole model to the inference engine. For a 7B in bf16 that is 14 GB. For a frontier 1T model checkpoint that is on the order of a terabyte. Per step. It turns out you do not have to. Between two consecutive RL optimizer steps, roughly 99% of bf16 weights are bit-identical (and never less […]

After building your Reachy Mini, you’ll install the conversation app and start talking to it. Until now, you had to send your audio to a server. But not anymore. Today we’ll walk you through running the whole stack locally. This stack is powered by speech-to-speech, our cascaded VAD → STT → LLM → TTS pipeline that exposes a Realtime API-compatible /v1/realtime WebSocket. Once you launch the backend, point the robot at it from the UI. Cascades are the most flexible […]

Artificial Analysis and IBM Software Innovation Lab are launching ITBench-AA, the first in a new series of benchmarks evaluating models on agentic enterprise IT tasks, starting with Site Reliability Engineering tasks where frontier models score below 50% ITBench-AA’s SRE tasks benchmark model performance on Kubernetes incident response, where models and agents must diagnose live systems by reading logs, tracing dependencies, and identifying root-cause entities across complex infrastructure. The underlying ITBench dataset has been developed by IBM, leveraging deep expertise in […]

What you cannot profile, you cannot optimize. Whether you are trying to squeeze more tokens per second out of a Large Language Model (LLM), shave milliseconds off inference, or just understand why your training loop runs slower than the spec sheet promises, the path eventually runs through profiling. The catch is that profiling has a steep on-ramp. The traces are dense walls of colored rectangles. The events carry intimidating names. Most tutorials assume you can already read them. So even […]
