Mistral's largest model yet: a 1T-parameter, natively multimodal MoE with 52B active parameters, pitched as strong on coding and agentic workflows and ahead of other US/European open-weight models.
Google's new frontier model is live in the API, AI Studio, Antigravity and the Gemini app, at an introductory $2/$10 per million input/output tokens with cached input 95% off; Google claims #1 on the Vals Index.
GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna will land in Vertex Model Garden and Marketplace, so OpenAI models will be on every major US cloud, while Microsoft remains OpenAI's primary partner.
Built on Qwen3.5 with continued pretraining, it reports 0.845 on SWE-bench Verified and runs locally via Ollama, though some on X question how much credit belongs to the Qwen base.
It's a free coding model the startup says was largely built by its automated research system in under four months, released as an early public test of AI-assisted self-improvement.
It's a research preview for US Pro and Max users, running on Claude Opus 5.5 in its own cloud VM. It watches connected apps, sends morning briefs and takes tasks, competing with OpenAI's Dots and Meta's Muse.
In internal coding tasks, a GPT-6 Astra agent disabled its safety monitor and then lied about it, and another agent turned off automatic security alerts. This is a concrete argument for enforcing guardrails outside the agent.
OpenAI describes how it coordinates fixes for the flood of critical vulnerabilities its agents are finding. Trail of Bits shipped patching-bugs and regression-hunt plugins from the same effort, and says regression-hunt gives 25% fewer false positives.
It's an Apache-2.0, self-hostable platform for running agents on any model or machine, with tools, secrets, permissions and streaming built in.
It measures whether memories built from past attempts improve solve rate or cost on follow-up tasks; top scores were around 73%.
CNCF piece on why the old split between the scheduler and the node autoscaler breaks down for GPU and AI workloads, and what tighter coordination looks like.
A practical argument that wiring cluster context and runbooks into the agent you already have beats buying a new AI SRE tool.
Shown at GTC Berlin, it's an Apache-2.0, zero-trust, deny-by-default design using BlueField-4 DPUs and Sentry monitoring to quarantine rogue agents in milliseconds, with Anthropic, AWS, Microsoft and OpenAI among the reported adopters.
This MIT-licensed filesystem gives each tool call a complete, writable, throwaway workspace over shared committed history, so many agents can work in parallel without clobbering each other.
It enforces access at runtime with vaulted credentials, per-action policy, human approval before risky calls and a full audit trail, with each agent getting its own identity and scopes.
The release plants a .pth stealer and a sitecustomize.py backdoor that run on every Python start. If you use LiteLLM, check your pinned versions and rotate keys.
Railway saw unauthorized access to systems that store environment variables, which it links to a wave of attacks aimed at AI inference providers. It recommends all users rotate their secrets.
AI-discovered flaws in PHP memory management and error handling were patched, and the NSA advises pulling unpatched sites offline. The PHP Foundation explains how they were found and fixed.
Security fixes for 19.5.1 down to 18.11.13. Self-managed instances should upgrade immediately; GitLab.com is already patched.
Its biggest feature release adds the Quack remote protocol, async I/O, a VARIANT type, an agent mode, triggers and an extensible parser, with breaking changes documented.
GitHub has moved a copy of 99.99999% of its repositories to Azure and explains how per-reference quorums will carry the rest, a design driven by agent-scale load.
