A developer demonstrates building a practical AI assistant in Python using OpenAI's API, emphasizing that production-ready AI requires more than just a model call. The post covers prompt design, error…
Stepyard, a new open-source automation runner, lets developers define YAML pipelines with built-in LLM steps and Python plugins, running entirely on local machines without cloud dependencies. The tool…
Decagon deployed self-evolving AI agents that automatically improve their own prompts without human intervention, using a feedback loop that tests and promotes winning versions. The team found that th…
A developer introduced airules, a Python library that adds static typing and rule-based logic to decision-making systems, reducing reliance on LLMs for deterministic cases. The library uses typed fact…
A developer reveals three structural cost leaks in LLM pipelines: uniform model routing, synchronous processing, and lack of caching. After addressing these issues, the same workload can cost far less…
Openfusion, an open-source drop-in compound-model proxy, lets users point any OpenAI-compatible tool at it to fan out prompts to a panel of LLMs in parallel, then a judge model synthesizes a single an…
A developer built an open schema for structuring multi-agent teams, addressing the lack of portability across platforms. The schema defines agents with fields like key, name, title, role, and model, a…
A developer has published a step-by-step guide for building a LangGraph-based customer support agent called ShopBot, which uses memory patterns, human-in-the-loop approval, and real tools to handle e-…
An engineer who built an AI agent for a job board platform processing 10,000+ listings daily discovered that AI agents fail silently in ways that look like success, such as rate limit hits causing inc…
A new study reveals that large language models exhibit a strong brand bias, recommending well-known brands 100% of the time when product specifications are identical, but this dominance can be broken …
NexArt introduces Certified Execution Records (CERs) for AI systems, enabling independent verification of execution records without trusting the provider. The CER uses canonical JSON, integrity anchor…
A study of LLM-as-a-Judge evaluations found that pairwise preferences flip 13.6% of the time on average, with some questions reaching a 56% flip rate, and GPT-4o-mini showed a significant first-positi…
A developer building a price comparison tool for outdoor gear replaced brittle regex and CSS selectors with an LLM-based parser to extract product details from 30 e-commerce sites. Using GPT-4o-mini w…
A developer advocates for query rewriting before retrieval to improve search accuracy in support bots, using cheap LLM calls to generate multiple query variants or step-back abstractions. The techniqu…
A developer abandoned building a custom document Q&A system after struggling with fine-tuning and keyword search, then built a working prototype using Retrieval-Augmented Generation (RAG) with OpenAI …
Upgrading to a smarter LLM judge from the same model family as the generator does not reduce bias — it makes it worse. When a capable model evaluates its own output, it defends wrong answers 86% of th…
A systematic human audit of the NL-to-FOL benchmarks FOLIO and MALLS found that approximately 39% and 36% of entries, respectively, contain incorrect FOL formalizations, with additional errors in ambi…
A developer reduced an AI writing tool's API costs from $487 to $52 per month—an 89% savings—by implementing task-specific minimal prompts, embedding similarity caching, and intelligent model routing.…
Researchers evaluating English-to-Hindi translation systems found that five major generative models frequently erase gender cues through ergative and honorific constructions, failing to preserve gende…
A solo developer built Loopers, an open-source reverse proxy that enforces hard dollar caps on AI API spending, after discovering developers were facing bills as high as $80,000 from runaway LLM costs…
