Cloudflare security-audit-skill is #1 on GitHub weekly trending

Cloudflare's multi-stage security-audit skill for coding agents: one agent finds vulnerabilities and an independent verifier re-checks each. The repo was created in June and blew up this week. As of Oct 28: +16,388 stars this week, 51,025 total, #1 on GitHub weekly trending.

Model

Block introduces the Dessa speech model; download is not open

Dessa is a full-duplex speech-to-speech model trained from scratch only on human conversation audio (no text, no pretrained model). It interrupts, backchannels, and laughs. Block says it was trained on one NVIDIA GB200 NVL72 and runs locally on a high-end MacBook (M4 Max and up). It is not released: download is “coming soon”, early access is only for a small group of AI safety researchers, and no open-source release or release date has been announced. One X post had 13.49M views and 69K likes.

Model

Mistral Large 4 weights are expected by month’s end and were not on Hugging Face as of Oct 28 evening

1T parameters, 49B active. Mistral said the weights would come by the end of the month. A community post claims Oct 31. As of Oct 28 evening it was not on Hugging Face. Treat “released today” posts as unconfirmed.

Why it matters This is an upcoming open-weights release, not a model you can download yet.

Open source

REA lets coding agents reverse-engineer binaries, APKs, and Electron apps

An MIT-licensed CLI and MCP server. v6.8.0 shipped on Oct 25. About 400K stars. It was the #1 GitHub AI project by stars gained from Oct 19–25.

Model

Nanbeige4.3-33B, a 33B Apache-2.0 model for agentic coding

33B parameters, Apache-2.0, 512K context, aimed at agentic coding. As of Oct 28: Hugging Face trending #3, 699 likes, 7,412 downloads. The vendor reports Terminal-Bench 2.1 at 80.9 (unverified).

Model

Google launches flagship model Gemini 4 Argon

A new flagship for coding and long agentic work. One 1M-token window covers input and output (a single response can exceed 64K, up to about 1M). Google says it is #1 on the Vals Index. Intro price is $2 / $10 per 1M input/output tokens through Nov 30, then $4 / $20. A linked report frames it as Google's comeback after scrapping Gemini 3.5 Pro and a DeepMind leadership shake-up.

Open source

ComfyUI open-source app contest deadline is Oct 30

Prizes are $25K, with an open-weights track. A related update is the ComfyUI OPENjutsu post.

Why it matters A wave of open ComfyUI apps is likely around the deadline.

Open source

magpie, a local gateway between the OpenAI, Anthropic, and Gemini APIs

A local LLM gateway on 127.0.0.1:3425. It speaks the OpenAI, Anthropic, and Gemini APIs and converts between them, so Claude Code can use Kimi and Codex can use DeepSeek. It switches accounts when a quota runs out. MIT license. 24,419 stars as of Oct 28. No separate release date was recorded.

Open source

HKU DeepTutor, an open-source personalized AI tutor

HKU's open-source personalized AI tutor. As of Oct 28: +2,376 stars that day, 47,336 total.

Open source

Design skills that push coding agents toward less AI-looking UI are climbing

As of Oct 28: hallmark +2,109 stars that day, 40,092 total; impeccable +6,713 stars this week, 91,473 total.

Model

Baidu Unlimited-OCR-2, an open-source OCR model for long documents

A 3.3B mixture-of-experts model for long-document OCR, MIT license. As of Oct 28: Hugging Face trending #12, 300 likes, 8,357 downloads.

Research

Jev outputs calibrated probabilities instead of text; Kev is an open reimplementation

TypeSafe's Jev is a closed “decision model” that outputs calibrated probabilities instead of text, as an alternative to using an LLM as a judge. Open reimplementations exist, including Kev. The reported window is September–October, with no single day.

Nothing in this range.
