Red Hat vs Together AI

CISA flags three actively exploited Linux kernel flaws

The US Cybersecurity and Infrastructure Security Agency (CISA) has added three Linux kernel vulnerabilities to its Known Exploited Vulnerabilities Catalog (KEV), indicating they are being actively exploited. The flaws, tracked as CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964, are rated as 'critical' or 'high' severity. Red Hat has confirmed exploitation via publicly known exploits. The vulnerabilities can lead to system crashes, privilege escalation, and remote code execution. CISA has ordered US federal agencies to patch affected systems within three days or temporarily take them offline. Patches are available in the kernel, and administrators are urged to apply them urgently. No details on the threat actors or targets have been disclosed yet.

• CISA added three Linux kernel vulnerabilities to its KEV catalog: CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964.
• Red Hat confirmed that all three vulnerabilities are exploited in real attacks via publicly known exploits.
• CVE-2025-39682 involves an error in processing empty TLS records in kernel TLS, potentially leading to system crashes and code injection.

Tokens-per-Second Benchmarks Explained

This technical guide explains what "tokens per second" (tok/s) actually measures for local LLM inference, why single-user tok/s numbers can be misleading, and how concurrency, batching, and prompt processing change the observed speed. It contrasts single-user latency with server throughput, highlights vLLM's continuous-batching advantage versus Ollama under high concurrency, defines related metrics (P99 latency, time to first token / TTFT), and provides practical measurement advice using tools like Ollama and vLLM and calculators from notAcalculator. The article also gives realistic tok/s expectations for different model sizes on consumer hardware and lists practical tips for reading and running benchmarks yourself.

• Tokens are the unit of both billing and speed for LLMs; tokenization affects cost and measured tok/s.
• Under a Red Hat benchmark on an A100 40GB with Llama 3.1 8B, vLLM peaked around 793 tok/s combined throughput versus about 41 tok/s for Ollama at high concurrency (~19x gap).
• vLLM's key innovation is continuous batching (plus PagedAttention), which increases total throughput under concurrency compared with single-request processing tools.

Introducing Together Link: Run open models inside the harness you already use

Together AI announces Together Link, a new product that allows running open models within existing harnesses, alongside new research blog posts on ThunderKittens for NVIDIA Vera Rubin NVL72, ThunderAgent, and ICML 2026 participation.

Open or Closed AI: Founders' Choices at TechCrunch Disrupt 2026

The article previews upcoming discussions at TechCrunch Disrupt 2026 (Oct 13-15, San Francisco) on AI model strategy. It highlights how startups increasingly use multiple models—open and proprietary—for different tasks, weighing cost, performance, and flexibility. Sessions feature leaders from Together AI, Pathway, Oumi, Nvidia, and Ricursive Intelligence. Topics include whether to build, customize, or rent AI models, optimizing AI hardware (chip design), and trade-offs between frontier APIs (like OpenAI, Google) and open-weight models. The article emphasizes that model choice shapes product differentiation, infrastructure needs, and long-term business viability. It's a conference promotion with substantive insights on AI architecture decisions.

• TechCrunch Disrupt 2026 takes place Oct 13-15 at Moscone West, San Francisco.
• The conference features 200+ sessions, 250+ speakers, and 300+ exhibiting startups.
• Sessions cover multi-model strategies, custom model development, and AI-designed hardware.

Together AI Product Team Shares AI-Native Workflow Stack

Together AI's product team, including CPO Charles Zedlewski and PMs Necoline Hubner and Pavneet Ahluwalia, outlined their AI-native product development stack in a podcast. The stack comprises four components: a shared context repository accessible by any AI harness, skills for feature research and PRD writing, an orchestrator for leadership, and agent evals. The team emphasizes collective productivity over individual gains, using multiple models like GLM and Kimi instead of relying solely on Anthropic. They validate products through agent-based tests, checking if AI agents can complete tasks using their documentation and API. The article also highlights Together AI's $8.3 billion valuation from its Series C round.

• Together AI is valued at $8.3 billion.
• Together AI's product team uses a four-component AI-native stack: shared context repo, skills, orchestrator, and agent evals.
• The team uses multiple AI models (e.g., GLM, Kimi) rather than only Anthropic's models.
