DuckDB v2.0 Preview: From Embedded Database to Server

DuckDB officially released a v2.0 preview, announcing a major version codenamed 'Cyanoptera' for this fall, with core changes including DuckDB as a server, triggers, VARIANT type, asynchronous I/O, a new SQL parser and default storage format, and a rewritten C API. Over 10,000 commits since v1.5. Why it matters: For developers relying on DuckDB for embedded analytics or data engineering, the server mode and storage format changes mean deployment shapes and compatibility strategies need reassessment, and the VARIANT type directly benefits semi-structured data processing.

Qwen3.8 27B Scores 52 on Artificial Analysis, Approaching Super-Large Models

Artificial Analysis data shows Qwen3.8 27B scores 52 on the Intelligence Index, far exceeding the median of 9 for models of similar size, and is considered by the community to be on par with DeepSeek V4 and GPT-5.6 Luna Max. The model supports text and image inputs, with a context window of 256k tokens and generation volume of 160M tokens. Why it matters: If a 27B parameter scale can consistently approach frontier large models, local deployment and inference costs will drop significantly, which is a substantial benefit for agentic coding and self-hosted inference scenarios.

Comments generally marvel at its ability to punch above its weight, believing the performance is real and disruptive; but some question whether benchmarks may be distorted and note high inference costs.

Wiz Discloses: GitHub Copilot Autofix Let Through Vulnerability, Snowflake Internal Jira Compromised

Wiz Research's autonomous security research tool 'Red Agent' independently discovered and exploited a GitHub Actions injection vulnerability introduced by a Copilot-assisted PR and approved by AI review, ultimately accessing sensitive data in Snowflake's internal Jira. The entire process had no human intervention and occurred five days after the vulnerability went live. Why it matters: AI-assisted code review is entering production workflows, but this incident proves critical vulnerabilities can still be automatically approved; for teams relying on Copilot Autofix or CI/CD automation, human review mechanisms are indispensable.

Comments generally believe AI auto-fixes must undergo human review, with YAML and conditional logic especially prone to introducing vulnerabilities; but some argue responsibility lies with human processes rather than AI itself.

Amazon Confirmed to Destroy Rare Books for AI Training複数ソース ×3

404 Media placed an AirTag in a rare book and tracked it to Amazon's AI training facility VGT3 in Las Vegas, which specializes in cutting book spines and scanning pages. Amazon responded that it 'purchases books through commercial channels to improve products and services.' Why it matters: LLM training data is shifting from the public internet to scarce offline text resources, and copyright and ethical disputes will further escalate; for engineers and researchers concerned about training data compliance, this is an important industry signal.

GitHub Down Again, Discussions on Alternatives Heat Up複数ソース ×3

GitHub experienced intermittent outages, with Copilot authentication failing in some applications and users reporting inability to access PRs; the official status page showed normal but was actually unavailable. Discussions on Hacker News about alternatives scored 456 points. Why it matters: For teams relying on GitHub for code hosting, CI/CD, and Copilot, service stability is becoming a risk point; the feasibility of self-hosted GitLab, Gitea, or Forgejo is back in view.

Most recommend self-hosted GitLab, Gitea, or Forgejo as alternatives, but some believe self-hosting is complex to maintain and GitHub Enterprise is more stable.

Hi all! I finally just got around to testing out Qwen 3.8 27b. I'm using Unsloth's UD-Q8_K_XL quant as a sit-in replacement to Qwen 3.6 27b, same quant size. Wow -- this thing isn't messing around. I have many baseline test prompts to gauge the 'intelligence' and usability of the model, but a go-to one is asking it to do a 1:1 recreation of classic arcade games (like Galaga, Donkey Kong, Pac-Man, etc). I do this to see what little details it gets correct. I've tested this process on pretty much

The next generation of AI agents is increasingly moving beyond systems that answer isolated questions toward persistent personal assistants that can understand, remember, and continuously learn from users' experiences. Such assistants require long-term memory to accumulate and leverage user-specific experiences over time, yet existing benchmarks remain inadequate for realistic mobile settings, where experiences are heterogeneous, multimodal, evolving, and deeply personal. We introduce MobileMem,

Just wanted to raise some attention to this PR I filed if anyone would like to try it out. This adds an adaptive MTP mode to llama.cpp which employs a fairly simple counting-style state machine to determine the appropriate depth to set the MTP depth to dynamically. The goal here was to make it so people can stop worrying about what the best MTP depth to use is, and just let the server figure it out as it goes. Compared to an MTP of 3, then for very dense hard to predict prose and regular prose t

Hi HN! I'm Bek, founder of Speko, a platform that finds an optimal combination of speech-to-text, LLM, and text-to-speech models, given your constraints, among all our public benchmarked options, and tells you why.

I started building my markdown-svg-renderer tool in May , but I've since added enough features to it that it's worth talking about here again.

The tool is very simple. Navigate to markdown-svg-renderer in your browser and paste in some Markdown to see it rendered... or save that Markdown to a CORS-friendly

Agent skills represent a standardized format for packaging procedural knowledge and domain expertise, serving within agent harness systems as an essential mechanism to continually constrain a language model's behavior space for repeatable, high-quality task execution. However, because strong closed-source models entail high inference costs, current popular agent harnesses, such as Codex and OpenClaw, remain prohibitively expensive when deploying these skills to accomplish real-world tasks. The r

Instruction-tuned language models achieve strong performance across a range of generation tasks, but have also recently been shown to exhibit verbalized overconfidence. In question answering, verbalized model overconfidence may be associated with the consistency of the generated supporting rationales. In this paper, we study whether corresponding changes in the lexical diversity of generated answer rationales accompany changes in model confidence induced by instruction tuning. We evaluate three

arXiv:2608.13564v1 Announce Type: new Abstract: Evaluating language-model agents at scale increasingly relies on a second language model as an automatic judge, because the gold signal, an executable environment reward, is expensive, slow, or unavailable at deployment time. Such a judge is a reward-free proxy whose value depends on whether it can be trusted, yet existing judges either hand-write the scoring rubric, as in G-Eval, or fine-tune the judge's weights, and both tend to credit fluent but

Interactive game world models typically autoregress visual observations directly in pixel or latent space, forcing structured properties such as pose, geometry, and occlusion to be implicitly maintained by the same generative sequence. Over long horizons, errors in these latent world properties accumulate, making consistency and controllability fragile. We explicitly model the evolving world state, delegate exact geometric computation to a fixed, zero-parameter renderer, and leave the neural mod

arXiv:2608.13598v1 Announce Type: new Abstract: Agent evaluation relies almost entirely on outcome metrics such as success rate, which capture whether an agent succeeds but not how consistently it behaves. We argue that behavioral consistency across tasks is a distinct and measurable property, and we introduce the Behavioral Consistency Metric (BCM) to quantify it. BCM trains a model to predict task success from behavioral features of agent execution traces, derives a per-trajectory feature-attr

arXiv:2608.13591v1 Announce Type: new Abstract: High-confidence errors in large language models are often treated as evidence of fragile internal inference. We study a different possibility: stable miscalibration, where a confident wrong answer remains locally stable under small perturbations. We combine two diagnostics: a label-aware output-level audit score that ranks domains by confidence variation and overconfident mistakes under a forced-answer baseline, and an internal sensitivity probe th

This Ling 3.0 Tiny 8b param with 1.3b active is the fastest, smartest model I can run on my poor old pc, with 4gb vram. It actually runs lightning fast, like 36 token / sec, as smart as Qwen 3.5 9b / Gemma 12, (Very close), and even faster because of 1.3b active parameters. The Qwen 3.5 9b is running with like 5 token / sec, but this with 36 is finally the speed that i want. Very good open source model, I hope we'll get more of this tiny and really fast models, thank you! :)

Creative agents still lack an effective way to learn from high-quality human films, limiting their ability to produce cinematic-grade videos. A key challenge is the absence of a structured video representation that is both faithful to film content and directly usable for agentic reasoning and manipulation. To address the challenge, we propose the Agentic Video Auto-Encoder (AVA-Encoder), a framework for learning agent-native video representations via agentic auto-encoding. AVA-Encoder transforms

Interactive autoregressive video generation demands both low-latency rollouts and precise online control. Few-step distillation accelerates generation by reducing denoising steps, while online control imposes a causal constraint: frames and blocks should depend on history and controls available during generation. Existing video distribution matching distillation (DMD) pipelines, however, often supervise causal few-step students using bidirectional teachers that score complete clips. The score fo

Sorry for the slop, but I was impressed by this model as I have been testing Qwen3.8-27B Q8_0 locally on my ROG Flow Z13 (Ryzen AI Max+ 395, 128 GB unified memory) and this model was the only one who could made this short simulator (and I have tested a lot of models).

Every time I see a post about a newly released model, whether it be a comparison or shitting on it, I have to dig through the endless comments to see what quants they used and what their specs were. Its quite a common occurrence here in this sub to ask someone that's saying a model is underperforming, and when you ask what quantization they are running they say something like "oh im running q0.1bpw from nobodyknowswhothisguyis". Worst offender is with comparison posts. "Comparing the new Qwen3.8

Hi HN. I built 1667 for my own fiction work and now use it each day. This probably has a limited audience. Maybe an audience of one... Why a terminal interface for story writing? I'm a dev. I like to use terminals for a lot of stuff. Most WebUIs feel off to me. That's the only reason. One thing that bothers me about writing in existing tools is that they don't fit the way I write. The mental model of my story is a tree. I try many takes usually continue with just one, but sometimes I want to try

Apollo did not reach the Moon merely because its engineers could solve difficult equations. It succeeded by turning a distant ambition into a mission architecture of explicit objectives, simulation, verification, and repeated correction. AI now faces a similar transition: frontier models can solve difficult tasks once the problem, tools, and success criteria are specified, yet consequential real-world challenges rarely arrive in an executable or verifiable form.

arXiv:2608.13567v1 Announce Type: new Abstract: The human brain exhibits a striking degree of functional specialization, with distinct networks supporting language, formal reasoning, reasoning about other minds, and reasoning about the physical world. Is this modular organization a fundamental principle of how intelligent systems must be built, or an evolutionary accident specific to biological brains? Here, we test whether a similar organization emerges in Large Language Models--another class o

Yes it uses a ton more reasoning tokens than 3.6 did But test in on the same tasks with the other chinese models, glm 5.3, deepseek v4 flash and pro, etc it's really similar, and they are needed The reality is, we're just frustrated because our hardware do not allow most of us to have 1M context (I know that it's not supported yet) with 150 tps decode Furthermore, if you don't mind the quality drop, you can just add a reasoning budget, it will still be better than 3.6

Pose-driven human animation synthesizes a video of a target person from a single reference image and a driving pose stream. Real-time generation is essential for interactive applications such as live streaming, telepresence, and virtual avatars, yet diffusion-based systems require minutes to hours per clip, precluding responsive interaction. We present LiveAnimate, to our knowledge the first animation system to combine real-time streaming with stable long-form generation at billion scale, built

arXiv:2608.13607v1 Announce Type: new Abstract: Frontier LLMs are updated frequently and typically outperform their predecessors in aggregate. But aggregate gains say little about individual samples: an update can still cause sample-level regression, where a response correct under the old model becomes incorrect under the new one. This paper studies how to predict such regressions from signals available at inference time. We compare single-model signals (confidence, logit margin, attention entro

Pretty self explanatory. Could you folks shed some light on why these issues keep happening? I’ve noticed most posts and replies are just people coming to their own conclusions based on whatever published data. I think it would be helpful to get some actual, non-corporate/marketing information on the goings-on by those that actually see what’s happening on the inside. Thanks Can

Humanoid motion tracking is central to teleoperation and whole-body imitation, yet evaluation often disagrees with what people perceive in videos. Kinematic errors average per-frame pose differences but miss the physical artifacts that matter most, particularly unstable support and incorrect contacts such as foot skating and mistimed touch-downs. Meanwhile, widely used test suites are small and lack the diversity needed to stress contact-rich, long-horizon behaviors. We introduce HumanTracker to

Yes, it sucks to waste time waiting on 16K+ reasoning tokens alone. But here's the thing, this is only a 27B model trying to perform on par with 1T+ parameter models. Something has to be sacrificed, and that sacrifice is the amount of reasoning or trajectory tokens. This isn't new to LLMs whatsoever. Andrej Karpathy himself has said that LLMs need tokens to think. He mentioned this somewhere in his "Let's build GPT" / GPT video series, although I don't remember exactly when, if i am not mistaken
