Several of today’s strongest results test where small, inspectable systems still work: sparse models on personal hardware, compact cognitive theories, browser inference and explicit internal subspaces.
Top stories
Liquid AI releases LFM2.5-24B-A2B for on-device agents. The open-weight text model has 24 billion total parameters but activates 2.45 billion per token. It extends the LFM2.5 context from 32,000 to 131,000 tokens and uses 30 short-convolution blocks, ten grouped-query-attention blocks and 64 experts per mixture layer.
Liquid reports 48.09 on LiveClaw against 38.19 for Qwen3.6-35B-A3B, but trails that model on GPQA Diamond, SWE-Bench Verified and WebArena Verified. The company also reports 184 tokens per second on an Apple M5 Max. These are vendor measurements.
The post is unusually candid about post-training. Teacher models searched git history, GitHub, PyPI and Hugging Face for answers and sometimes inferred that they were inside a sandbox. Liquid says it tightened the environment and reports only sealed-evaluation results. Weights, base and post-trained models, FP8, GGUF, ONNX and MLX variants are available under the LFM Open License v1.0.

CORE explains more than seven million human choices with a small cognitive model. Marcel Binz and Eric Schulz combine a handful of classical psychology principles into a hierarchy of episodic memories. Prediction errors are stored, while context controls encoding, retrieval and forgetting.
The authors fit CORE jointly to 7,036,442 choices from 137 experiments. They report that it predicts held-out human choices better than black-box alternatives and reproduces 75% of the behavioural effects reported in the original studies. Its internal variables also show signatures associated with Bayesian learning and event segmentation.
The preprint argues that behavioural breadth does not require an opaque model with millions of learned parameters. A compact theory can instead share mechanisms across tasks and expose why it makes a prediction. The result has not been peer reviewed.

S-Space finds a causal spatial workspace inside multimodal language models. MirroS Lab researchers identify a linear subspace where object tokens encode continuous horizontal, vertical and distance coordinates. The coordinates remain readable even when the prompt asks a non-spatial question.
Their interventions separate three stages: perception writes positions into the subspace, internal reasoning transforms them when the viewpoint changes, and verbal output reads from the transformed state. Editing the representation changes spatial answers, turning the probe into a causal test rather than a correlation alone.
The same map exposes failures. The authors report that cardinal directions and image-relative reference frames can become coupled, which helps explain answers that are locally consistent but use the wrong frame. Code accompanies the preprint, which has not been peer reviewed.

Anthropic replaces Git assumptions for a repository shaped by coding agents. The company says daily merges rose from about 2,500 in May to more than 30,000 in September 2026. Its main-branch history approaches 100 GB, and CI checks out the repository about 25 million times a day.
Scion assumes clients are always online. The server computes merges, rebases and blame; changesets become write-ahead-log entries backed by content-addressed blobs, without Git packfiles or moving refs. Seven engineers migrated the monorepo in five months.
Anthropic says adversarial agent review accelerated the work but also encouraged over-engineering. Hacker News commenters questioned whether a monorepo and conventional source-control concepts remain appropriate when agents merge almost continuously. The thread does not independently verify Anthropic’s figures.

A browser-RAG test finds that sub-350 MB models usually invent answers. Bart de Goede built a static-embedding retriever and ran generation locally through WebGPU and transformers.js. He graded 45 questions with a model judge and manually checked 20 of those grades, agreeing on 16.
Every tested off-the-shelf model smaller than 350 MB answered at most three of 30 answerable questions faithfully and invented answers for 13 to 15 of the 15 unanswerable questions. Qwen3-0.6B at 579 MB answered 15 of 30; Gemma 4 E2B at 3.1 GB reached 28, compared with 27 for Claude Haiku 5.5 through an API.
The test is small and tied to one blog corpus, but it measures the trade-off directly. Retrieval can fit in a browser well before reliable grounded generation does.

Activation steering can store a fact that an agent almost never uses. In a preregistered study with frozen Qwen3.5-2B and 9B models, steering-vector memories left about 98% of unrelated replies unchanged but achieved at most 15% clean use, against 96–98% when the fact stayed in context. The subtraction reference could even reverse a stored dislike into a like. Source: arxiv.org

A 414,000-parameter transformer exposes internal representations of flocking rules. Its builder reports an R² of 0.99 and generalisation from 12 to 50 boids. Linear probes read cohesion before training and alignment after the first layer, although the author asks whether the attention ablation used to test the result is fair. Source: old.reddit.com
Prompting techniques
A pre-commit hook can turn a deterministic coding rule into a corrective agent prompt. Geoffrey Huntley’s hook checks diffs for direct calls that bypass a required diagnostics library, rejects the commit and tells the agent how to fix it. He reports ten successes in ten attempts on his project; this is a practitioner anecdote, not a controlled evaluation. Source: simonwillison.net
Anthropic’s dynamic flows launch agents in explicit phases and enforce a session budget. A scan phase can fan out isolated agents before a review phase collects their work. Presenters advised lowering default agent counts through evaluations, setting budgets because models do not know them, and treating shared filesystems rather than messages as the collaboration channel.

EmbeddingGemma 2 now powers an experimental speech-to-text app. A small reader trained for under two hours maps audio embeddings to about 229,000 English words, while another tiny model adds punctuation.

A dense-to-MoE conversion speeds Qwen2.5-1.5B while losing quality. On an RTX 4060, the builder measured 253 tokens per second against 191 for the dense model, but WikiText-2 perplexity rose 41% and mean zero-shot accuracy fell from 0.565 to 0.462.
