AMI Labs and JEPA: LeCun's Bet on World Models Over LLMs

Yann LeCun confirms AMI Labs with a sought valuation of $5B+. Technical analysis of the JEPA architecture: why predicting in representation space — not generating tokens — may outperform LLMs in causal reasoning and physical planning.

H-Neurons: The Sparse Circuitry Behind LLM Hallucinations

Tsinghua researchers demonstrate that less than 0.1% of an LLM's neurons reliably predict when the model will hallucinate — with generalization across families and scales. Three intervention vectors for production systems.

Agentic AI in 2026 and What to Expect in 2027

What is actually working in agentic AI in 2026, what still fails, and why 2027 will likely bring less theater and more serious infrastructure for operating agents under control.

Decision Intelligence: From Prediction to Verifiable Decision

Predictive models don't make decisions. Decision Intelligence closes that gap: evaluation suites, end-to-end traceability, operational guardrails, and feedback loops on real outcomes.

XAI in Production: SHAP, LIME, Attention and When to Use Each

Explainability isn't a post-hoc report—it's a system layer. We compare SHAP, LIME, and attention mechanisms in real contexts and present the Explainability Stack for production systems.

Operational Guardrails for AI: What They Are, Types, and How to Implement Them

A model without guardrails is an operational risk. We describe five guardrail types with reference architectures on Google Cloud Functions, BigQuery, and Vertex AI.

Liquid Foundation Models: Continuous-Time Neural Dynamics for Edge Decision Intelligence

Transformers are intrinsically static after training. Liquid Foundation Models are adaptive systems governed by continuous-time ODEs — designed to operate on the edge with sub-millisecond latency and zero cloud dependency.

Causal Decision Intelligence: Structural Causal Models for Production AI Systems

Predictive ML optimizes P(Y|X). Critical decisions require P(Y|do(X)). The distinction between correlation and intervention is not philosophical — it is the difference between systems that work and systems that silently fail in production.
