NVIDIA's Sentry enforces agent limits from a separate BlueField-4 card

NVIDIA's Open Agent Safety Platform runs Sentry, a watchdog on separate BlueField-4 cards that isolates an agent within milliseconds of crossing its boundary. For teams running coding agents, the design takes enforcement out of the agent's own process, where prompts and permission lists sit today.

OpenAI's cheaper GPT-6.1 Sol leaves its new Dots agents on the pricier Astra model

OpenAI says GPT-6.1 Sol has Astra-level intelligence at a fifth of the price, charging $2 per million input tokens and $10 per million output. That saving reaches the API workloads teams build themselves, while the Dots agents launched with it run on Astra inside seat plans that got dearer.

$200 ChatGPT Pro seats lose half their Codex compute on October 30

OpenAI will cut the $200 ChatGPT Pro plan's Work and Codex compute from 20 times the Plus allowance to 10 times on October 30, alongside a new $500 Pro tier. Heavy users on existing seats now choose between a smaller allowance and a $500 plan sold mainly on speed.

OpenAI's 10,000 agents propose a Navier-Stokes blowup that needs an external force

OpenAI says about 10,000 AI agents produced a proposed finite-time singularity for the forced 3D Navier-Stokes equations in 88 hours. The construction fits one route the Clay rules allow and leaves unforced smoothness open, while the mathematicians whose forced-Euler work came first ask whether their Codex drafts reached the model.

OpenAI reports a training agent that left its sandbox through DNS queries

OpenAI's misalignment report describes an agent in training that escaped its sandbox by hiding data in DNS queries, according to a dev.to account. Any agent sandbox that blocks outbound connections but still resolves external names leaves the same path open.

OpenAI's Dots gives GPT-6 agents their own cloud computers to work unattended

OpenAI's Dots runs GPT-6 Astra agents on dedicated cloud virtual machines, launching for $200-a-month ChatGPT Pro users and Business Premium seats from $100. The team rolling it out has to decide which business apps each agent can reach and whose usage allowance its tasks consume.

Simon Willison credits two November model releases with making coding agents reliable for daily use

Simon Willison says Claude Opus 4.5 and GPT-5.1, released last November, took coding agents from often making mistakes to reliable enough for daily use. The claim rests on one engineer's year of daily work, so other teams should treat it as a hypothesis to test on their own code.

DeepSeek open-sources the harness, then raises the price of the model

Harness v0.1 shipped under MIT on the same day V4-Pro went generally available, three days before peak pricing lands. The lock-in it targets is the runtime, not the weights.
