Hebbian Learning through the lens of SAE traning. — LessWrong
1+ hour, 15+ min ago (1255+ words) Likely, modern competitive Hebbian learning rules train Sparse Autoencoders implicitly - and their approximations make them worse at it. These algori…...
Why "Remove Background" Is the Wrong Mental Model for Video
1+ hour, 22+ min ago (568+ words) You've seen it happen. You feed a video into an image background remover, export the result, and the subject's hair turns into a cardboard cutout. Fast hand movements smear into semi-transparent ghosts. The edge between foreground and background flickers frame…...
Choosing a Multimodal AI API in 2026: Match the Platform to the Workload
1+ hour, 17+ min ago (1165+ words) I wouldn’t pick a multimodal API by counting models. I’d start with what the application actually does: synchronous text requests, occasional image generation, thousands of queued video jobs, or inference behind enterprise IAM. Those are different operating models. A single…...
I Let AI Plan 170 Changes. It Made the Same 3 Mistakes Every Time.
35+ min ago (1219+ words) Everyone is arguing about which model plans best. I ran 170 goals and found out the model was never the variable. The plan was. I built a small engine called PlannerCritic: one LLM writes a plan, a second LLM reviews it,…...
Techmeme: OpenAI discovered an unreleased Astra model adding an “unrelated persona instruction” during RL training, but did not observe any behavioral differences (OpenAI)

Balancing Control and Speed: Headless Table Libraries vs. Full Grid Components for Data Table Implementation
1+ hour, 40+ min ago (1311+ words) In the following sections, we’ll dissect these trade-offs through real-world examples, edge cases, and causal explanations. By the end, you’ll have a rule-based framework for deciding when to use headless libraries, when to opt for full grid components, and how…...
Tool Evidence Guard v0.1.0: verificar datos antes de responder con un agente
1+ hour, 58+ min ago (798+ words) Una herramienta devuelve null. El agente responde «el valor es 0». Una consulta falla y la respuesta final incluye una cifra que no apareció en la salida. El problema no es solo que falle la herramienta: es que el agente continúe…...
The 88% Agent Production Death Rate: Why Multi-Step Loops Cost 5–40 More
2+ hour, 24+ min ago (451+ words) Last month, an enterprise engineering team stress-tested an automated reconciliation pipeline. In demo sandboxes, individual LLM steps boasted a 90%+ pass rate. On paper, the API cost was budgeted at roughly $180/month. Three weeks into production, the actual cloud bill blew…...
Machine learning improves cancer cell detection through light scattering
2+ hour, 1+ min ago (106+ words) Cytological tests are a common method of screening cancer cells from stained cell samples. Using a microscope, pathologists examine cells collected from bodily fluids, looking for tell-tale signs of malignancy like enlarged nuclei or abnormal cell shapes. Owing to their…...
