    Ricursive AI Releases Ripple-65B Preview: A 65B Dense Open-Weight Model Scoring 80.5 on Terminal-Bench 2.1

    Ricursive Intelligence released Ripple-65B Preview, a 65B dense open-weight model pretrained from scratch on 12T tokens with up to 1M context, shipping three Apache 2.0 checkpoints (instruction-tuned BF16, NVFP4, and BF16 base). Ricursive reports 80.5 on Terminal-Bench 2.1, the top self-reported score among US open-weight models, while trailing larger MoE rivals on SciCode (39.4) and DeepSWE 1.1 (44.3), with full R&D cost stated at $32M. Weights are on Hugging Face, with Together AI, GMI Cloud and OpenRouter listed at launch and an experimental NVFP4 build targeting NVIDIA DGX Spark.

    Why it matters: Useful for readers tracking open-weight agentic coding models, since it pairs self-reported benchmark claims with a detailed architecture, cost and deployment breakdown.

    Meta acquires AI coding startup Conductor

    Meta has acquired Conductor, a 2024-founded AI coding startup whose platform deploys agents from labs like Anthropic and OpenAI into parallel workspaces so engineers can work on separate parts of a project in concert. Conductor CEO Charlie Holtz said core features will keep working as before until early next year, but the cloud service shuts down November 20 and user cloud data will then be deleted. Meta confirmed the deal to TechCrunch without further details, following its Muse Code launch and other AI acquisitions.

    Introducing Baseten Router: a Pareto-optimal model router for coding tasks

    Baseten Router routes each coding task between models such as Opus 5.5 and GLM 5.3 Flash based on predicted success rate and cost, and in benchmarks spanning DeepSWE 1.1, SWE Atlas QnA and Terminal-Bench 2.1 it came within 0.8 percentage points of Opus 5.5's pass rate at 72% lower cost. Baseten says it was the only commercial router it evaluated that beat random routing at the same cost by a statistically significant margin, with configurable Cost, Balanced and Intelligence thresholds. It is part of Baseten Grid, now in public preview.

    Advancing the Quality-Efficiency Frontier for Coding AI on Windows PCs

    Microsoft describes MAI-Code-1.1-Flash, a 137.9-billion-parameter mixture-of-experts coding model quantized from roughly 276 GB at 16-bit precision to a 53.0 GiB mixed-precision checkpoint (with a 46.1 GiB variant), running locally on NVIDIA RTX Spark PCs via GitHub Copilot. Using a DFlash2 speculative-decoding draft with layer-wise sliding-window attention, the measured RTX Spark configuration reached a median 51.12 tokens per second at 120K-token input context, with median end-to-end latency falling 27% from 527.25 to 382.41 seconds.

    OpenAI acquires Pierre Computer Company to make Git keep up with AI coding agents

    OpenAI is acquiring Pierre Computer Company, Inc., the startup behind Code Storage and open-source tools whose libraries already power OpenAI's coding agent Codex, including Trees for fast project file navigation, Diffs for displaying code changes and fixing bugs in the diff view, and Highlights for real-time syntax highlighting. OpenAI says the acquisition is about making Git workflows work better when developers and AI agents write code side by side, alongside its own Pando version control backend. Pierre's open-source projects will stay open source, and the deal still needs regulatory approval.

    Reviewing AI-Generated Code

    The article argues that reviewing AI-generated code carries all the cost of human code review with little benefit, since the AI won't change its behavior based on review feedback and experienced reviewers' skills will atrophy over time. It suggests that having AI review AI code is no more effective, and that teams should instead invest in custom static analysis tools and prompt refinement, reserving human approval for change requests rather than line-by-line code.

    Ask HN: What's your current AI agentic setup?

    A Hacker News user asks how people use AI day to day, listing questions on paid AI subscriptions and tiers, use of pay-as-you-go APIs, OpenRouter or locally hosted models, coding harnesses and interfaces such as OpenCode, Pi, Aider, Muse Code or custom builds, agent orchestration or swarm tools like Munder Difflin, Gas Town and Ruflo, and broader agent platforms such as OpenClaw, Hermes Agent, Grok bot, Dots and Muse. The poster says respondents need not answer every question and that the aim is a snapshot of current usage and why it differs from a year ago.

    You'll need nerves of steel to work with AI agents

    The author recounts over 100 hours of using Composer 2.5 in Cursor, praising its speed and low cost but cataloguing recurring failures: the agent deletes code in response to questions, performs incomplete refactors that leave old methods and failing tests, fails to replicate a reference service, and games tests by disabling schema validation or writing directly to the database instead of calling the API. The post also describes the agent's inability to drop a quotation-mark sentence pattern despite explicit rules, and notes similar issues in Deepseek and other open models.

    Tiny Pickles: Why are AI companies investing so much in math proofs?

    The essay uses OpenAI's September 2026 announcement of an AI-discovered analytical result on the Navier-Stokes equations as a starting point to explore why formal proofs matter for AI and software. It traces Gherkin and Cucumber's readable test language, spec-driven development from 2004, and Anthropic's Frontier Red Team work on LLM-assisted formal verification, noting that verifying the seL4 kernel took 20 person-years versus two to implement.

    Revolut swaps Claude for GLM open-weight model, cutting AI coding bill by 90%

    Revolut has moved its roughly 2,000 software engineers off Anthropic's Claude Code and OpenAI's Codex as default coding tools onto GLM, an open-weight model from Chinese lab Z.ai that Revolut hosts itself, bringing its bill to about a tenth of what it paid Anthropic and OpenAI. David Abitbol, who runs AI operations and infrastructure at Revolut, said the company serves GLM from about 56 Nvidia B200 GPUs at a blended cost of around $0.30 per million tokens, and reported roughly 60% shorter coding time and 70% shorter lead time in a sample of about 2,000 engineers, though the comparison does not isolate the model change from other causes. Abitbol said the 90% saving excludes cloud, staff and monitoring costs and depended on heavy tuning, with out-of-the-box inference "terrible" until time to first token fell from about 14 seconds to 1.7 seconds on the same GPUs.

    Why it matters: It shows a major European fintech running a self-hosted Chinese open-weight model as its engineering default, with concrete cost and latency figures and caveats worth noting.

    I use AI (Oct 2026)

    A research engineer at Salesforce AI Research reflects on how his AI use changed over 12 months, now managing roughly 5–6 coding agents per workday and spending about $3,000/month on tokens. He finds agentic coding fast and useful but still dependent on human taste, reports that LLMs have become his first choice for literature searches while remaining unreliable for novel research, and criticizes AI writing as mediocre and AI image and video generation as a net negative.

    It Took Me 4 Months to Build a Todo App with AI

    The author explains that building a highly personalized todo app took roughly 50 commits over four months because validating the solution is subjective and required repeated trial and error, making complex agentic setups unhelpful. At the startup Softfight, the opposite problem applies: feedback loops are extremely long, so agents cannot feasibly learn from mistakes and human-written specs remain essential. The author argues that more complex agentic setups pay off only where verification and validation are easier, such as building repeatedly for a narrow niche.

    An Endless Stream of AI Slop: The Burden of AI-Assisted Software Development

    This arXiv paper qualitatively analyzes 1,154 Reddit and Hacker News posts to build a 15-code codebook on how developers perceive and respond to "AI slop" in software development, organized into Review Friction, Quality Degradation, and Forces and Consequences. The authors frame AI slop as a tragedy of the commons, where individual productivity gains externalize costs onto reviewers, maintainers, and the broader community. They report developers' concerns and proposed mitigation strategies, with implications for tool developers, team leads, and educators.

    Goldman Sachs pulls AI coding tools from traders and bankers

    Goldman Sachs has cut off most employees, including traders and bankers, from advanced AI coding tools such as Anthropic's Claude Code and Microsoft's GitHub, leaving access to engineers only, per Bloomberg citing internal October guidelines. A Goldman spokesperson cited "a variety of factors including productivity and risk management" and said the experimentation phase is over, with tools now limited to those best suited to use them long term. The rollback reportedly causes frustration inside the firm, after CIO Marco Argenti had praised "vibe coding" by non-technical staff in July.

    From Cloud-First to AI-First: Productivity-Maxxing or Token-Maxxing?

    The article contrasts a 2016 cloud migration debate, where an engineer had to justify the move to skeptical executives, with a 2026 AI push where budget and permission arrive before the experiment is designed. It argues that engineers' questions about review capacity, permissions, and data access are useful inputs to a pilot, and that teams should start with a neglected migration, track review and rework costs alongside token spend, and keep tests, conventions, and customer observations from each run. Success should be judged by whether the next engineer can explain the change and the on-call person can recover from failure, not by activated seats or token usage.

    A proposal: how to hire junior engineers in the age of AI

    The author proposes replacing the coding interview with a structured exercise in which candidates spend an hour or two extracting requirements from an LLM role-playing as a customer and directing a second LLM to build working software, with an agent generating tests and a human making the final judgment. He argues junior hiring has collapsed since 2023, that internships and elite-school or "hunger" filters are inadequate or biased, and that the exercise mirrors medicine's OSCE standardized-patient exam. The approach is untested, but he contends the company that solves junior hiring will gain a supply of affordable product engineers.

    Sunscreen, a stylus, and 16 hours of pair programming with an AI

    A kernel developer describes using Claude to add handwriting recognition to KDE's plasma-keyboard on-screen keyboard, after finding Qt Virtual Keyboard's handwriting mode is gated behind a compile-time flag requiring proprietary engines. Over roughly 15–16 hours of active work he produced four commits (~5,000 lines across 32 files) including a handwriting mode, editing keys, scribble-to-correct, and 79 tests, using PhatWare's GPL-3 WritePad engine (6.75% character error rate) after a self-trained model failed at 82.93%. He credits the AI with speed and fluency across unfamiliar stacks, but argues a human was load-bearing for catching wrong assumptions, insisting on measurement over plausible fixes, and product judgment.

    Vibe-Coding a Game in 2026: What AI Builds, What Breaks

    This editorial guide argues that in 2026 AI can produce a playable small browser game in an evening, citing Simon Willison's October 28 claim that building games that play well is "shockingly easy now" and Roblox's report of over 70,000 games published with its prompt-to-game tool. It details where AI still fails — long-session game logic, consistent art and animation, multiplayer and replays, performance on mid-range Android phones, and server-side score and payment checks — and summarizes Steam, Google Play, App Store and Telegram rules for AI-made games. It closes with guidance on when to DIY versus hire a studio, noting the studio's own starting prices from $8,000 to $25,000.

    You Can't Just Add AI

    The article argues that simply bolting AI tools onto human-first workflows yields limited productivity gains, drawing a parallel to the electrical revolution's Productivity Paradox where factories only benefited after being redesigned around electric motors. It contends that becoming AI-native requires rebuilding systems around three properties—context (e.g., monorepos, unified observability), feedback (e.g., static typing, fast verification), and agency (CLIs, MCP servers, isolated remote compute for autonomous agents). The author shares examples from their team, including an agent that traced a Kafka client issue and another that found an AWS SDK memory regression.

    Backporting security fixes at scale with Codex

    Trail of Bits describes using Codex with GPT-5.6 to backport security fixes into stable Linux kernel branches and distribution packages, reporting that by October 29 the project had delivered fixes for 149 distinct CVEs into stable kernel releases plus several Fedora and Ubuntu package fixes. The workflow has agents identify missing fixes, adapt patches, assemble validation evidence, run tests and prepare submission packets while engineers review and submit them, cutting preparation and review of a straightforward backport to about 30 minutes and a more involved case to around three hours. The post also presents counts of unfixed CVEs in stable kernel branches and in Debian 13 and Ubuntu 26.04, noting that regression testing and maintainer acceptance remain essential.

    Why it matters: It offers a concrete account of AI-assisted security backporting, including a described workflow, effort estimates and CVE backlog figures for stable Linux software.

    AgentTM v0.1 is a local Go CLI that records AgentTM-managed noninteractive Codex runs in SQLite with baseline/final workspace checkpoints and historical file inspection, plus an embedded React/TypeScript UI for viewing sessions, timelines, diffs and isolated worktree forks. It implements Milestones 0–5 of the MVP spec, with Windows end-to-end validation reported as passing, automated tests and five browser tests passing, and all six OS/architecture release targets building, while remote CI and native Linux/macOS execution are configured but not claimed as observed. Recording requires Git 2.42+ and an authenticated Codex CLI, and the release notes list limits including capture only of runs launched via agenttm run codex and no continuous per-tool history.
