Qwen3.5-0.8B gets a 0.016% weight tweak as Postman’s AI plugins crash the party

35 Stories

A post claiming Astra can improve Qwen by reading raw weights alone overstates the results: raw-weight tests covered tiny networks, while language-model trials used Python. In one Qwen3.5-0.8B test, editing 0.016% of weights raised its MATH-500 score from 7.9% to 48.1%. Qwen 3.8 27B also identified Pac-Man, Pong and Breakout from raw weights without tools, but misclassified Freeway after a lengthy run.

Postman 12.33.4 allegedly installed AI coding plugins and changed global agent settings without clear opt-in; the report does not claim data was exfiltrated. Stringman is a $795 open-source cable robot that moves a gripper around a room and offers a Python API for local automation. Namespace built a scalable macOS cloud from rack-mounted MacBooks, using virtualization and automated image distribution to manage large system images.

The 'Astra can read and write weights to improve Qwen' post is misleading

The 'Astra can read and write weights to improve Qwen' post is misleading

The post’s headline claim that Astra improves Qwen “just by looking at raw weights” is misleading: only three small-network experiments (17K–172K weights) use raw floats without tools or execution. All language-model experiments use Python; Qwen3.5-0.8B is run on up to 50 batches of practice problems, and editing 0.016% of weights raises MATH-500 from 7.9% to 48.1%. Thus the results combine distinct techniques, not one unified weight-understanding capability.

Hacker NewsHacker News discussion· 1005 pts
People disagree whether the headline misled: some say it blurred small raw-weight tests with Qwen’s Python-based analysis; others say the research explained the distinction. Some still find the demonstrations exciting, while critics call the Qwen fix familiar.

Like GPT-6 Astra, Qwen 3.8 27B can interpret model weights

Qwen 3.8 27B demonstrated Weight-Space Programming by identifying games from raw neural-network weights without tools. Running locally, it correctly recognized Pac-Man, Pong, and Breakout after 46–65 minutes and 43,506 reasoning tokens for Pac-Man, but misclassified Freeway. The results replicate part of a paper’s findings for GPT-6 Astra, which also describes editing weights to improve models. The author emphasizes that interpreting weights without tools differs from using code to modify and train models.

Hacker NewsHacker News discussion· 636 pts
Some see promise, while others question whether recognizing familiar games proves genuine weight interpretation or whether edits preserve broader performance. One developer says Qwen inferred a small image-filter network’s purpose and improved it using scripts and retraining.
RedditReddit discussion· 489 pts
Many caution that reading weights is not self-improvement: Qwen interpreted weights, but no example shows it changing them or broadly improving a model. Others see promise for more efficient, specialized models.

British fintech Revolut slashes AI coding costs 10x by cutting out Claude and going self-hosted

British fintech Revolut slashes AI coding costs 10x by cutting out Claude and going self-hosted

Revolut cut AI coding inference costs by about 90% in under a year by making self-hosted GLM models its default instead of relying mainly on Claude and Codex. After deploying tools to about 2,000 engineers, it reported 60% faster coding and 70% shorter lead times. GLM-5.3 now runs on 56 Nvidia B200 GPUs; quantization, serving, and context tuning deliver sub-three-second first-token latency and about 200 tokens per second. A model router sends vision tasks to Gemini or GPT Luna.

RedditReddit discussion· 1732 pts
Many see self-hosted models as a practical, cheaper alternative that gives companies more control, while others question whether savings justify multimillion-dollar hardware and say this approach remains out of reach for ordinary users.

Postman silently auto-installs AI plugins and attempts to share all API data

Postman silently auto-installs AI plugins and attempts to share all API data

Postman 12.33.4 allegedly automatically installed Codex and Claude Code plugins, a CLI, a remote MCP connection, and a startup hook on macOS, changing global agent configuration without clear opt-in. Logs show an auto-existing-upgrade installed both plugins; the hook broadly routes API tasks through Postman skills, while installer code attempts to approve its own hook. The MCP connection failed authentication. The report requests consent-boundary fixes, rollback, explicit opt-in, and narrower instructions, while not claiming data exfiltration.

Hacker NewsHacker News discussion· 1319 pts
Many say Postman has become bloated and intrusive, and recommend simpler, local-first alternatives such as Bruno or Yaak. Some note its enterprise reach and shared collections still make it useful.

Schools that block Google’s A.I. will lose student access to its search engine

Schools that block Google’s A.I. will lose student access to its search engine

Google will disable A.I. tools in its K-12 software early next year unless school administrators opt in, but schools that ban A.I. entirely will also lose access to Google Search. Google says Search and A.I. are deeply integrated, so affected students will see a school message instead of search results. The policy leverages Google’s dominant role in education, where its apps and Chromebooks are widely used.

Hacker NewsHacker News discussion· 576 pts
Many see Google's bundling of AI with Search as coercive, saying schools cannot block AI without losing a basic research tool. Others argue Search is now AI-integrated and schools can choose alternatives.

Fujifilm to boost tape production 5x as AI fuels archiving demand

Fujifilm will invest about 10 billion yen ($63 million) to increase magnetic tape production capacity fivefold versus fiscal 2025 levels, driven by generative AI’s exponential data growth and archiving demand. From fiscal 2026–2028, its Kanagawa Factory, Odawara site will expand manufacturing and staffing, mainly for FUJIFILM LTO Ultrium10. Cloud and data-center operators use LTO tape for economical, high-volume backups that can be air-gapped, helping protect data from ransomware and other cyberattacks.

RTX 5090 with 64GB and 96GB VRAM 'confirmed' by US GPU repair tech

RTX 5090 with 64GB and 96GB VRAM 'confirmed' by US GPU repair tech

Greg Sky, a US GPU repair technician, claims modified NVIDIA GeForce RTX 5090 cards with 64GB and 96GB of GDDR7 VRAM exist, doubling the stock 32GB. The proposed 96GB version would use 32 memory modules in a clamshell PCB layout, with 3GB chips, but Sky has provided no photos, benchmarks, firmware details, or evidence that NVIDIA’s drivers recognize the added memory. The claim remains unverified, despite his GPU Lab’s previous 48GB RTX 4090 upgrades.

RedditReddit discussion· 684 pts
Many are intrigued by the extra memory for local AI, but doubt it will work reliably and want proof; others say a modified 5090 could still trail the Pro 6000 in compute performance.

Mac at Any Scale

Mac at Any Scale

Namespace built a scalable macOS cloud by racking MacBooks, virtualizing macOS with Apple’s Virtualization framework, and automating image distribution. Each laptop uses IP KVM, 10G Ethernet, custom cooling, and four cables; Apple limits hosts to two macOS VMs. Namespace uses gVisor-based networking reaching 4 Gbps, sparse and layered APFS-backed images, and peer-to-peer fleet distribution to handle 500 GB images. Mac Minis and Studios will simplify operations, while automated workflows enable rapid Xcode updates.

Hacker NewsHacker News discussion· 373 pts
Many say cloud Macs cost more than buying and running Minis, especially for steady workloads; others value renting for occasional use or easier scaling. Some blame Apple’s VM limits and lack of server options.
