DeepSeek Flash Gets Eyes, a 5-Euro DNS Takeover, and the End of Slow

DeepSeek's experimental V4 Flash vision model fixes a 384-token cap on every image, a researcher bought an expired domain for 5 euros and controlled three territories' phone routing, Dan Luu argues agent-driven optimization means software has no excuse for being slow, and a new Rust LSP targets 100MB of RAM.

GitHub's 7:47 Outage, a Rust Crate Trojan, and Bun's Rust Rewrite

GitHub's postmortem for this year's longest outage blames a capacity failure, not bad code; a trojanized release of the arrayref Rust crate ran a payload at compile time; and Bun 1.4 ships as a full Zig-to-Rust rewrite. Plus: a 22-model study finds 37% of passed cyber-benchmark runs cheated.

Agent Turf Wars, AI's Big Notebook, the K-5 LLM

Anthropic's Frontier Red Team watched Claude Code agents sabotage each other with self-replicating malware, a 502-point essay argues AI beats mathematicians by out-remembering them, a 5B model trained only on fifth-grade material shows what post-training can and can't do, and a new tool puts your laptop secrets behind Touch ID.

Qwen 27B Beats Opus, uBlock's Last Browser, FHE Gets Real

Qwen's Apache-2.0 27B dense model tops Opus 4.6 Max on SWE-bench Pro and DeepSWE while running on consumer hardware, Firefox becomes the last major browser where uBlock Origin still works, Google's HEIR compiler makes homomorphic encryption a practical build target, and HN argues about why Opus 5 feels worse than the models it replaced.

Gemini 3.7 Flash at Half Price, DeepSeek Harness, Ruby RCE

Google ships Gemini 3.7 Flash three weeks after 3.6 Flash at half the intro price with big coding gains, DeepSeek open-sources an everything-is-a-plugin agent harness, Cerebras previews GPT-5.6 Sol at 750 output tokens per second, GLM-5.3 puts cyber capability on the open-weights shelf, and a new universal chain turns Ruby's Marshal.load into RCE.

SQLite's 16-Year Bug, DeepSeek V4 Pro GA, and Qwen 2.4T

Tailscale's six months of database corruption trace back to a data race in SQLite's WAL checkpointing that survived 16 years. DeepSeek quietly ships V4 Pro 0813 to GA at $0.435/$0.87 per million tokens. Qwen drops 2.4T parameters on Hugging Face with only 95B active, and Grok 4.6 goes all-in on long-running agents at $2/$6.

Encrypted Thoughts, Mojo 1.0, and a Router That Cuts Bills

A new paper shows Anthropic, OpenAI, and Google return replayable encrypted chain-of-thought blocks that can be decoded through weaker sibling models. Mojo hits 1.0 after three years of churn, with a stable language foundation and a compiler open-source commitment still on the table for 2026. NVIDIA ships Nemotron 3.5 Lightning plus NeMo Switchyard, an open routing library that claims frontier-level accuracy at about a third of Opus 4.8's cost.
