Keenable AI open-sources NEEDLE, a dynamic web search benchmark
Keenable AI has open-sourced NEEDLE, a new benchmark designed to evaluate web search APIs by dynamically generating query sets hourly and daily. This approach prevents agents from accessing pre-existing answers, ensuring a more accurate assessment of their retrieval capabilities…
-
LLM logit bias bans fail 81% of the time, analysis finds
A technical analysis reveals that the common method of banning specific words in LLM outputs by adjusting logit bias is largely ineffective. This approach, which involves setting negative log probabilities for tokens corresponding to a word, fails 81.25% of the time. The ineffec…

Google ADK configuration error causes LLM tool misuse
A developer encountered a significant issue while using Google's Agent Development Kit (ADK) with Google Cloud Vertex AI. The problem stemmed from incorrectly structuring the configuration for model requests, specifically placing tool definitions within `generationConfig` instea…
-
AI agent summaries audited against tool call logs to detect hidden failures
A new auditing loop for AI agents has been proposed, which verifies agent summaries against actual tool call logs. This system, implemented as a script, replays tool call traces to build a fact ledger and then evaluates agent claims, marking them as PASS, UNSUPPORTED, or CONTRAD…
-
RAG systems fail due to data pipeline errors, not LLMs
Retrieval-augmented generation (RAG) systems can produce incorrect answers due to issues in the data processing pipeline, rather than flaws in the language model itself. Common problems include chunking documents with fixed lengths that split meaningful content, using embedding …
