Large language model (LLM) news — GPT-4, Claude, Gemini, Llama, Mistral and the latest research on training, fine-tuning, RLHF, and deployment of LLMs.
A developer discovered that their AI agent was providing inaccurate status reports because the underlying backlog.md file was not being updated. The agent faithfully read the stale file, leading to a mismatch between the…
Boris Cherny, creator of Claude Code, says he no longer prompts Claude directly, instead using loops that prompt the agent and figure out what to do. Anthropic's research supports this shift, where agents run code and de…
A user describes using Codex as a personal agent to automate tasks across Gmail, WhatsApp, Telegram, iMessage, Google Drive, and other tools, enabling workflows like drafting emails and updating records with minimal manu…
A developer received a $340 AWS bill for a side-project LLM summarization tool after underestimating costs due to system prompt tokens and higher-than-expected usage. To prevent such surprises, they built APICalculators.…
A developer introduced Cronos (Version 2.0), a framework for human-validated vibe coding and agentic software engineering. The methodology, tested over three months, delivered nearly 4x productivity gains by organizing d…
Miami startup Subquadratic claims to have solved a decade-old bottleneck in AI models by replacing dense attention with sparse attention, achieving 56x speed gains and dramatic cost reductions. Independent tests by Appen…
Researchers from Princeton University, Together AI, Meta, Colfax Research, NVIDIA, and Georgia Tech introduced FlashAttention-4, an algorithm and kernel co-design that optimizes attention for Blackwell GPUs by overlappin…
Spec-Driven Development (SDD) has gone mainstream in 2026 as a disciplined counterweight to 'vibe coding,' making precise executable specifications the source of truth while treating code as a generated artifact. The pra…
A cloud architect rebuilt their inference layer to slash AI API costs by 60% while maintaining sub-2-second p99 latency. By implementing a tiered model routing system that directs simple queries to cheaper models like De…
A developer created a Python script that displays OpenAI Codex rate-limit reset credits with a live expiry countdown. The tool reads authentication from the Codex CLI's auth file and calls the OpenAI API to fetch credit …
Google is downloading its 4GB Gemini Nano AI model onto users' computers via Chrome without clear notification. The lightweight model powers on-device features like scam detection but consumes significant storage and RAM…
Jack Dorsey's Block revealed that its internal AI engineering system, Builderbot, now accounts for 15% of all production code changes at the company. The system, built on Block's open-source framework goose and Anthropic…
Sen. Marsha Blackburn is negotiating with the White House on a bill package that would trade child safety and deepfake protections for preemption over state AI laws. The Fable incident has spurred Congress and the G7 to …
A developer built rabbitholes, a browser extension that lets users highlight text on any webpage to get instant explanations from Claude Haiku 4.5 via a shadow-DOM tooltip. Every word in the explanation is clickable, all…
Google's Gemma 2 models demonstrate that architectural efficiency can deliver competitive performance with fewer parameters. The 27B model rivals models twice its size through hybrid attention, Grouped-Query Attention, a…
Apple has overhauled Siri with AI in the iOS 27 beta, delivering a consistent experience across all devices. The company confirmed in a new interview that making Siri identical on every platform was an intentional goal, …
A developer argues that engineers get the most out of AI coding tools like Claude, Copilot, and ChatGPT by treating them as senior colleagues rather than search engines. The key is to do 70% of the debugging work first—i…
A developer building vLLM from source on an AWS g5 instance with Ubuntu 26.04 and Python 3.14 encountered multiple version-skew, driver, and toolchain issues, including a pitfall where missing nvidia-smi falsely indicate…
A developer testing heterogeneous AI code review found that context and prompt quality matter more than model lineage. Running Claude Code with full repo access and adversarial prompts caught all planted bugs, while Gemi…
A developer built a local-first RAG tool called Study Assistant that implements a multi-provider fallback chain to ensure reliability. The system prioritizes local Ollama inference but automatically switches to cloud pro…
