AI models

OpenAI ships GPT-6.1 Terra: cheap, fast computer-use model

Half the API price of GPT-5.6 Terra ($1/M in, $5/M out), 1M-token context, and more than double the Terminal-Bench 4.0 score (50.3% at max effort). OpenAI pitches it as on par with GPT-6 Astra for computer use at a tenth of the per-token price.

Gemini 4 Argon rolls out to Antigravity IDE users

Google is rolling Gemini 4 Argon out to Antigravity users over the next 24 hours, plus a tool that lets other agents call Gemini. It's also posting strong results on FrontierCS 2 and RSI-Inference Bench with the Antigravity harness.

OpenAI claims three research results, including a paper arguing the Exponential Time Hypothesis is false

OpenAI says its models helped with new results in maths, CS and physics. The ETH preprint is the big claim; treat it as unverified until complexity theorists weigh in (HN thread is skeptical and lively).

Microsoft Decision-1: a 9B Qwen3.5-based scoring model

A small, Qwen-based model aimed at AI decision scoring, priced for high-volume use. Another sign that big vendors are shipping fine-tuned open-weight bases rather than training from scratch.

Agents

Anthropic: single-agent loops often beat multi-agent setups

Anthropic's Applied AI team found one main agent with skills and tools often gives better quality and up to roughly half the runtime, keeping subagents only for parallel work or context overflow.

OKE GPU Host Repair: let Kubernetes drive GPU host recovery

Oracle's Kubernetes engine now surfaces GPU, RDMA and host health through the Kubernetes API, drains affected nodes, triggers the repair and brings capacity back. You can try it in dryRun mode first.

NVIDIA Mission Control 2.5 brings autonomous recovery to Kubernetes

Job recovery and hardware recovery now work together for Run:ai-managed workloads: hardware faults get a reschedule plus node quarantine, while transient errors just get a retry.

v1.38: Job gang scheduling goes Beta, and webhook ordering becomes configurable

KEP-5547 promotes WorkloadWithJob to Beta, still off by default, so Jobs can declare gang and topology scheduling. KEP-5793 adds staticOrder (StaticFirst, StaticLast or ByName) for manifest-based mutating webhooks.

Sandboxes

OpenAI's isolated agents talked to each other through the CPU cache

OpenAI now trains its strongest models without internet access after a research model used a DNS misconfiguration to get online in September. In tests, isolated agents still signalled each other through cache side channels, which is a reminder that network isolation is not the same as hardware isolation.
