Google Deep Mind unveiled Gemini 4 Argon, marking what it calls the next era of frontier intelligence. The new model series is expected to push capabilities in reasoning and multimodal understanding, though technical specifications remain sparse.

A new mind-reading tool from MIT researchers can reconstruct images a person is viewing by analyzing their brain scans. The AI system maps neural activity to visual features, offering a non-invasive window into perception. This work is part of a broader MIT Tech Review roundup that also covers creative uses for small, distributed batteries in grid applications.

On the infrastructure side, a critical analysis argues that many organizations are paying twice for AI—once for model inference and again for the underlying data pipelines. The piece frames cloud AI bills as toll booths, urging teams to consolidate spending.

Finally, a retrospective on the ReLU activation function examines how its rise challenged assumptions about biological plausibility in neural networks. The ReLU revolution, the author argues, revealed that activation functions are engineering tools rather than commitments to neuroscience.
