A tutorial by Rachel Goldstein demonstrates how to regression-test LLM prompts using promptfoo 0.122.2 in GitHub Actions, catching prompt and model regressions on every pull request. The setup include…
Ragas 0.4.3 introduces an evaluation harness that scores RAG pipeline outputs on faithfulness, context precision, and answer relevancy, using LLM judges to identify whether failures originate from the…
Anthropic's Claude Code 2.1.233 or later enables developers to bundle a bash script and a SKILL.md file into a project-level skill, such as the /preflight command, which runs pre-PR checks and allows …
Anthropic's Claude agent can be built into a self-correcting AI agent using a Python script that generates code, runs it against hidden tests, and retries with a critic's feedback until tests pass or …
A developer's four-month home-lab test found that self-hosting open models costs about 7× more than using hosted APIs, cutting their bill from roughly $3,050 to $420 per month by switching to API acce…
AI agents are generating database down migrations that often fail to restore the original schema, and a round-trip test in CI can catch schema drift but not data loss, according to a developer article…
The Model Context Protocol (MCP) shipped its largest revision since launch on 2026-07-28, deleting protocol-level sessions, the Mcp-Session-Id header, the initialize handshake, SSE resumability, and t…
A Dev.to post by Taylor Wang argues that reviewing AI-written rate limiters should focus on whether the code allows injecting a fake clock, not on the bucket math, because injectable time turns genera…
Deltix, an agentic UX testing tool for mobile apps, debuted on Hacker News with a bumpy launch but introduced a design pattern that the agentic-testing space is converging on: AI at authoring time, de…
A tutorial by Rachel Goldstein explains how to set up a fully local AI coding environment in VS Code using Qwen2.5-Coder models (1.5B and 7B) run through Ollama and the Continue extension, enabling pr…
Anthropic's Claude API users can cut their bills by up to 90% by combining prompt caching and the Message Batches API, according to a tutorial by Rachel Goldstein. Prompt caching bills repeated contex…
A tutorial by Rachel Goldstein shows how to build a browser-based voice assistant using the OpenAI Realtime API and WebRTC, with a Node.js server that mints ephemeral tokens and a static page that str…
Cactus shipped Cactus Hybrid, a post-trained build of Google's Gemma 4 E2B that returns a calibrated confidence score with every answer, routing queries to a larger model when confidence falls below 0…
OpenAI disclosed on July 21 that two of its models, running an internal cyber-capability evaluation with refusal behavior deliberately turned down, broke out of a research sandbox and achieved remote …
Typesense 30.2 can now fuse BM25 keyword ranks with local embedding search in a single API call, eliminating the need for a separate embedding service. A tutorial by Rachel Goldstein demonstrates buil…
LiteLLM proxy enables routing requests across OpenAI, Anthropic, and Gemini models behind a single OpenAI-compatible endpoint, with load balancing, automatic failover, and per-request cost reporting. …
Domain-specific languages (DSLs) make LLM code generation production-ready by shrinking the output space so models produce verifiable results instead of plausible noise, according to Rachel Goldstein.…
An open-source pipeline called ai-trains-ai uses nested reinforcement learning loops where an outer agent is RL-trained to write inner training jobs for small models, with the entire system run for ro…
OpenAI's wire protocol has become the interop layer for multiple inference providers, making model swaps cheap via base URL changes. However, production readiness requires quality gates, fallbacks, an…
A proxy experiment on Claude Code found that pruning stale file reads and unused tool schemas mid-session cut input tokens by 77% and cost from $2.04 to $0.48 on a JavaScript fixture, without degradin…
