A developer built an n8n agent that reads a lead's website before writing cold emails and refuses to write when it cannot find sufficient evidence. The workflow fetches the lead's homepage, extracts b…
A new benchmark called QIMG-7 reveals that multimodal retrieval-augmented generation systems suffer significant accuracy drops when faced with polluted data, with the GPT-4o-mini stack falling from 0.…
Researchers at arXiv identified a silent policy-violation failure mode in tool-using LLM agents, where tools execute forbidden state transitions without error signals. In the τ²-bench airline domain, …
A tutorial shows developers how to give AI agents persistent long-term memory using Postgres with the pgvector extension and OpenAI embeddings, eliminating the need for external vector databases. The …
A developer tested HyDE (Hypothetical Document Embeddings) against standard retrieval on three query types and found it improved conceptual searches but failed on internal company policy and exact pro…
Correctover has built a detection framework to catch silent model swaps in production LLM systems, where providers return responses from different models than requested without notice. The framework o…
A developer tested a support bot's compliance with two AGENTS.md rules using the muster testing framework. The bot consistently refused to leak an API token but repeatedly violated the rule against us…
A new open-source benchmark, Truth Benchmark, automatically detects when code does not match its documentation claims. The project provides a dataset of 52 labeled examples across multiple programming…
Anthropic's Claude API and OpenAI's API offer developers distinct trade-offs in 2026, with Claude providing a 200K-token context window versus OpenAI's 128K, and Anthropic's prompt caching reducing in…
A developer built and ran an identical multi-step research workflow using both LangGraph (with OpenAI's real API) and Locus StateGraph (with OCI GenAI via BOAT-OC1), both calling gpt-4o-mini. The side…
