AI News Summary

Industry strategy is converging on agents. OpenAI's Greg Brockman signaled an agent-first pivot ahead of a likely IPO filing, while AI21 shut down its model team and DeepSeek built its first 'Harness team'.

Policy and safety developments:

Trump reversed course on an executive order requiring AI safety reviews, citing China competition — a win for big tech.
Nous Research released Contrastive Neuron Attribution (CNA), identifying MLP neurons that encode refusal; ablating 0.1% of activations cut refusal rates >50% across Llama and Qwen models (1B–72B).

Open-source infrastructure tooling:

Tencent open-sourced TencentDB Agent Memory, a 4-tier local memory pipeline (MIT license) for long-horizon agents.
Perplexity released Bumblebee, a Go-based supply-chain scanner for developer endpoints covering packages, extensions, and MCP configs.
NVIDIA Nemotron-Labs unveiled diffusion language models targeting speed-of-light text generation.

[AINews] All Model Labs are now Agent Labs

By Unknown

85 score

AI Analysis

Building on yesterday's Social buzz from Greg Brockman, Greg Brockman signaled OpenAI's pivot toward agents-as-product ahead of a likely IPO filing, reversing prior 'pure model' stance. AI21 shuttered its model team to pivot to agents, and DeepSeek is building its first 'Harness team', signaling industry-wide convergence on agent products.

Ahead of OpenAI’s likely IPO filing next week, Greg makes the latest in a series of comments where Model Labs are increasingly also building Agents as the product:The quote is a big reversal of stance from a position ~uniformly held by anyone who worked at Team Big Model, including his previous head of OpenAI Labs:This comes with the shuttering of AI21’s model team, which is now pivoting to agents:and even the venerable DeepSeek is now building a “Harness team” for the fi

How big tech got its way on Trump’s AI executive order

By Nick Robins-Early

82 score

AI Analysis

Continuing our coverage from yesterday, Trump abruptly reversed course on signing an executive order requiring government safety reviews of new AI models before release, citing competition with China. The reversal is seen as a victory for big tech lobbying against AI regulation.

The US president’s reversal on calling for a safety review of new AI models is a green light for tech’s unchecked powerOnly hours before Donald Trump was set to sign a long-awaited executive order on Thursday that would have called for a government safety review of new artificial intelligence models before their release, the president abruptly backed out. Despite growing public backlash to the technology and experts warning new models will pose critical security risks, Trump vowed the US governm

Nous Research Releases Contrastive Neuron Attribution (CNA): Sparse MLP Circuit Steering Without SAE Training or Weight Modification

By Asif Razzaq

75 score

AI Analysis

Nous Research released Contrastive Neuron Attribution (CNA), a method to identify MLP neurons responsible for refusal behavior in instruct-tuned LLMs. Ablating just 0.1% of activations reduced refusal rates by over 50% across Llama and Qwen models from 1B to 72B parameters.

Instruction-tuned language models refuse harmful requests. But which part of the model is actually responsible — and how does that mechanism get installed during training? A new research from Nous Research team takes a neuron-level look at this question. The Nous research team developed contrastive neuron attribution (CNA), a method that identifies the specific MLP neurons whose activations most distinguish harmful from benign prompts. By ablating just 0.1% of MLP activations, they reduced refus

Tencent Open-Sources TencentDB Agent Memory: A 4-Tier Local Memory Pipeline for AI Agents

By Michal Sutter

68 score

AI Analysis

Tencent open-sourced TencentDB Agent Memory under MIT license, a 4-tier local memory pipeline for AI agents combining symbolic short-term and layered long-term memory. It uses local SQLite with sqlite-vec by default and integrates with OpenClaw and Hermes Agent.

Tencent has released TencentDB Agent Memory, an open-source memory system for AI agents. The project ships under the MIT license. It targets a problem familiar to anyone shipping long-horizon agents: context bloat and recall failure. It is symbolic short-term memory along with layered long-term memory. It integrates with OpenClaw as a plugin and with the Hermes Agent through a Gateway adapter. The default backend is local SQLite with the sqlite-vec extension, so no external API is required.

Perplexity Open-Sources Bumblebee: A Read-Only Supply-Chain Scanner for Developer Endpoints

By Asif Razzaq

30 score

AI Analysis

As first announced on Social yesterday, Perplexity open-sourced Bumblebee, a Go-based read-only supply-chain inventory scanner for macOS/Linux developer endpoints. It targets packages, editor extensions, and MCP configs to address growing developer-machine attack surface.

Attackers increasingly target the packages, editor extensions, and AI tool configs on developer machines and not just production systems. Perplexity has open-sourced an internal tool it uses to address this problem. Perplexity released Bumblebee on GitHub. The tool is a read-only inventory collector for macOS and Linux developer endpoints. It is written entirely in Go and carries zero non-stdlib dependencies. Perplexity already uses it internally to protect developer systems behind its search

Build a SuperClaude Framework Workflow with Commands, Agents, Modes, and Session Memory

By Sana Hassan

AI Analysis

Tutorial demonstrating how to build workflows using SuperClaude Framework on top of the Anthropic API, with commands, agents, modes, and session memory.

In this tutorial, we build an advanced workflow using the SuperClaude Framework as a structured layer on top of the Anthropic API. We clone the framework, discover its commands, agents, and modes, and create a Python bridge that dynamically loads the relevant Markdown behavior files into the system prompt before each model call. Through practical examples, we explore brainstorming, frontend implementation, security analysis, business strategy, deep research planning, token-efficient responses, a
