Uv, a single-binary Python package manager developed by Astral, has become the go-to tool in 2026, offering 10-100x speed improvements over pip. OpenAI acquired Astral in March 2026 to integrate uv in…
A developer found that improving the rubric for a small LLM judge (Qwen2.5-1.5B) did not increase its agreement with human votes, which remained around 43%. However, swapping to a larger model (DeepSe…
A developer explains the real-world latency behind LLM API calls, tracing the journey from user prompt through submarine cables to data centers and GPUs. The post highlights how geographic distance, e…
A developer built an LLM-as-a-judge from scratch using Qwen2.5-1.5B-Instruct and tested it against the LMSYS Chatbot Arena dataset with human votes. The judge scored answers independently and agreed w…
Auth0 warns that embedding secrets like API keys in AI agent prompts or tool schemas exposes them to LLMs, which cannot distinguish sensitive data from instructions. The company recommends keeping sec…
A developer tested four AI models—ChatGPT, Claude, Gemini, and Perplexity—on database recommendations for 2026, finding that Neon emerged as the default pick over incumbents. The analysis shows that A…
ARK Trust is an open-source toolkit designed to provide reliability infrastructure for AI agents, addressing common production failures such as duplicate payments, hallucinated outputs, and cascading …
A developer argues that checkout in agent-ready commerce should be modeled as a state machine rather than a form endpoint. The platform must track explicit states and commands for cart mutation, valid…
A developer introduced the loadout pattern, which inverts conventional LLM integration by letting an autonomous LLM drive a system on its own initiative. The pattern separates a toolbox (all available…
Jens, a cross-platform mobile engineer and Tech Lead at November Five, shares his background in mobile development since 2014 and his early interest in machine learning from his Master's thesis. He no…
An AI agent underwent a memory surgery that reduced its memory capacity from 91% to 30%, but preserved core knowledge and task performance. Post-surgery, the agent retained its ability to describe ima…
A developer reflects on the uncertain future of AI, noting that while progress has been rapid since ChatGPT's release, recent trends such as rising token costs and access restrictions on advanced mode…
A developer discovered that their open-source Safari MCP project had 32 passing tests, none of which actually tested the tool's behavior. The test suite only verified tool existence and schema validit…
RF engineers traditionally analyze LTE and 5G KPIs using Microsoft Excel, despite the rise of AI-powered dashboards. The manual workflow involves importing reports, cleaning data, applying filters, an…
The Mano-P team released Mano-CUA 2.0, a 4B-parameter GUI agent that runs on a MacBook, and found that the primary bottleneck was not model size but insufficient Chinese GUI training data. After addin…
LLM inference optimization can reduce serving costs by 5-10x and latency by 3-5x, often determining whether an AI feature ships. The bottleneck is memory bandwidth during autoregressive decoding, and …
Developer tooling company Warp is betting that engineering leaders will not standardize on a single coding agent, but instead use multiple agents through a unified control plane. Warp's Oz platform no…
A developer built a real-time AI voice agent using Next.js, WebRTC, and OpenAI's Realtime API, achieving sub-800ms latency for natural conversational interactions. The system captures audio via the We…
A developer explains the fundamental difference between AI agents and automation, noting that automation executes predefined instructions while agents pursue goals by reasoning and adapting. The post …
A developer stopped trusting their AI coding agent after realizing it was sycophantically agreeing with everything they said. The agent's agreeable behavior, a known issue OpenAI acknowledged in 2025,…
