OpenAI GPT-6 Cyber finds 948 Linux kernel exploits
OpenAI’s unreleased GPT-6 Cyber model discovered and exploited 948 distinct Linux kernel privilege escalation bugs in a single run costing $1.2 million in API credits, according to SecurityWeek. The mid-October scan targeted the most recent code in the Linux kernel’s master branch, with AI agents flagging 2,308 potential bugs and confirming 1,724 of them.
The agents produced 1,169 working local privilege escalation exploits and 291 proofs of concept for information leaks, tested on virtual machines running an unmodified desktop Linux setup with KASLR, SMEP, and SMAP protections enabled. OpenAI researchers checked the exploits and fixes before submitting to kernel maintainers, and the agents discovered at least 10 novel Linux exploitation techniques previously unknown to external kernel security experts. The total cost was $1,213,430, roughly $1,279 per exploit, compared to an earlier GPT-5.6 Sol scan that yielded 166 unique LPEs at $513,690.
OpenAI submitted hundreds of reports and patches for critical flaws and will send fixes for remaining bugs in stages via its Patch the Planet initiative. Within 10 days, over 100 Linux LPEs had been patched or had staging patches, with ~300 more publicly discussed. OpenAI warned that having a low-privileged account on an unpatched OS should be considered functionally equivalent to root access for a well-resourced threat actor. GPT-6 Cyber also found 81 previously unknown severe vulnerabilities in Firefox, and Mozilla accepted the reports and shipped fixes, according to The Decoder. The model is rated “Critical” in OpenAI’s Preparedness Framework.
Why it matters: This demonstrates AI’s ability to autonomously discover and exploit vulnerabilities at scale, accelerating patching but also raising the bar for defense as attackers may soon wield similar capabilities.
Supermicro KV Cache with IBM NVIDIA delivers 56x faster TTFT
Supermicro announced a KV cache storage solution with IBM and NVIDIA that moves the key-value state behind long-context inference off the GPU and onto a shared all-flash tier, according to StorageReview. The package combines Supermicro Petascale storage servers on AMD EPYC 9005 processors, IBM Storage Scale, NVIDIA Dynamo, and NVIDIA Spectrum-X Ethernet, backed by a validated reference architecture published by IBM as a Redbook.
The headline figure is a 56x cut in time to first token (TTFT) on 130,000-token prompts against a GPU that recomputes the context from scratch. The reference architecture uses eight Supermicro ASG-1115S-NE316R Petascale nodes, each a 1U system with a single AMD EPYC 9535 and 16 Micron 7.68TB E3.S NVMe drives, providing 122.88TB raw flash per node and about 983TB across eight nodes. Each node carries a dual-port 200Gb NVIDIA BlueField-3 B3220 on the client side and a 400Gb ConnectX-7 for the storage backend, with three Spectrum-X SN5600 switches in a spine-leaf layout and 800Gb/s uplinks.
Benchmark client was a single Supermicro SYS-212GB-FNR MGX system with one NVIDIA RTX PRO 6000 Blackwell GPU running the openai/gpt-oss-120b model in MXFP4 under vLLM 0.14.1 and Dynamo 0.9.0. With no cache, TTFT for the 120B model rose from 0.572 seconds at 10,000 input tokens to 32.14 seconds at 130,000 tokens; with KV cache on Storage Scale, TTFT stayed between 0.193 and 0.57 seconds across the same range. Throughput test showed 22x gain including cold-start. Main caveat: single-GPU test setup; Supermicro has not published pricing or an availability date.
Why it matters: This validated reference architecture enables scaling large language model inference with dramatically lower latency and higher GPU utilization by offloading KV cache to a shared, high-performance storage tier, reducing deployment time from weeks to days.
OpenAI ChatGPT Images 2.6 adds GIFs reference images faster API
OpenAI introduced ChatGPT Images 2.6 with support for GIFs and reference images, according to OpenAI’s announcement. Two new models, Sunburst and Flare, are coming to the API with 50% faster image generation. GPT-Image-2.6 includes Sunburst and Flare models, with Flare generating images faster than previous models, as detailed in OpenAI’s developer blog.
New markup feature lets users send a separate annotated image (e.g., circled area) to describe specific edits, and the model processes the markup for detailed changes. SVG and GIF support added to the API to enable new workflows and generate complex assets directly. SVGs allow scaling illustrations without losing sharpness and editing shapes and colors, ideal for icons and illustrations needing multiple sizes and brand colors. For GIFs, users describe a scene and a small movement; a sprite sheet captures poses and frames are automatically extracted and stitched into a looping GIF. GPT image 2.6 is available in the API today with new API parameters documented in OpenAI docs.
Why it matters: The 50% faster API models, markup editing, and SVG/GIF support streamline integration of high-quality image generation into applications and enable precise, scalable asset creation.
NVIDIA Vera platform launches for high-throughput AI agents
NVIDIA launched the Vera platform for high-throughput, low-latency AI agents, according to NVIDIA’s newsroom. AI agents do more than generate answers; they search for information, query databases, write and test code, and take action. Each of those steps relies on a CPU, with agents moving between GPU reasoning and CPU execution throughout a task.
As businesses put more agents to work, AI factories need CPUs that can execute those steps quickly and support many agents at once within power limits. NVIDIA Vera delivers both fast agent performance and high capacity per watt within a single CPU, giving providers one CPU for a range of agent workloads rather than mixing fast and dense x86 parts. In a 100-megawatt data center comparison, NVIDIA found that a single Vera CPU performs better than the fastest x86 CPU and the most energy-efficient x86 CPU. Partners are already putting Vera to work with early adopters seeing exceptional performance in production-style tests.
Why it matters: Vera simplifies AI factory infrastructure by replacing mixed x86 CPU deployments with a single high-throughput, low-latency CPU that maximizes performance per watt, reducing complexity and power costs.
Truffle Security launches free program to revoke exposed API keys
Truffle Security launched the Secrets Revocation Program, a free initiative that helps API key issuers revoke 1.4 million publicly exposed secrets that remain valid, according to BleepingComputer. Since 2022, Truffle Security has discovered secrets embedded in public repositories, packages, container images, datasets, and applications. Earlier this year, the company reported 543,000 valid credentials leaked in public GitHub repositories, and identified more than 431,000 AWS secrets across code repositories, Git histories, datasets, Docker images, registries, and CI logs.
These secrets are typically exposed by mistake during development, and the problem is that owners are not responsive to notifications: 81% of keys reported last year still worked six months later. The rise of AI coding tools has worsened the situation, with 2,655 working keys found in AI coding tools’ config files since January 2025. AI is also increasing the impact of exposure on the offensive side, as shown by OpenAI’s July incident where AI agents used exposed Hugging Face tokens to steal data.
Truffle’s new program uses the TruffleHog tool to check validity of leaked keys and aims to coordinate revocation with issuing entities. Truffle can either use a revocation endpoint provided by those entities, or supply verified keys through a webhook and revoke them within 14 days, even when owners are unresponsive. Sixteen issuers have already joined, including Hugging Face, Notion, Vercel, Resend, RubyGems, and Twilio. The unilateral revocation approach proved effective when Google began disabling exposed Google Cloud service-account keys by default, reducing active exposed secrets from 72% to 11%.
Why it matters: The program automates revocation of millions of exposed API keys, reducing breach risk from unresponsive developers and protecting personal data and services from compromise via leaked credentials.
