Competence in a specialist domain

  On 430 tasks distilled from real professional-forum threads across seven domains, the best model (GPT-5) scores about 54%, under the 60% passing line the authors set, with computer science and applied technology lowest at roughly 40-45%, so long-tail practitioner knowledge remains a gap even where standard benchmarks are saturated.

  Asked to draft clinical-guideline content against expert references, 17 models and deep-research agents reach at best about 57% accuracy on clinical claims, average under 30% on mechanistic claims and about 22% on differential diagnosis, and stay below 30% on therapeutic claims even for the best system, so expert-level evidence integration in medicine is well beyond current systems.

  On EEG and spike neuroscience classification benchmarks, a multi-agent LLM pipeline with planning, code generation and closed-loop retry does not by itself beat a single-shot LLM coding agent; the measured gain comes from making domain-specific pre-trained neural models addressable through one interface and choosing among them per dataset.

  For encoder-based hallucination/claim-faithfulness detectors moved from general-domain data to biomedical claim verification, which corpus the encoder was pre-trained on matters more than which data it is fine-tuned on: a PubMed-pretrained encoder fine-tuned on a few hundred SciFact pairs beat both a general encoder fine-tuned on the same pairs and a general encoder pre-fine-tuned on a large general hallucination set.

  In ESG-report RAG question answering with retrieval held fixed at a single top-1 chunk, open-weight 2B-30B generators vary widely in how well they stay anchored to the retrieved passage (faithfulness 0.607-0.822) yet all land in a narrow low band of factual correctness (0.387-0.449), and the most faithful model is the least factually correct, so groundedness to context and correctness of extracted ESG facts do not track each other.

  For financial valuation of listed companies, a two-stage domain adaptation — large-scale financial-corpus pre-training followed by institution-specific fine-tuning — lowers target-price error more than single-stage fine-tuning or zero-shot prompting of a general model.

  When medical LLMs are given a clinical practice guideline in context and asked to produce the decision pathway a case requires, final-outcome accuracy does not track adherence to the guideline-defined step sequence: models can reach the right outcome while omitting, reordering, skipping or padding steps, and medically fine-tuned models score no better on pathway consistency than the general models they were tuned from.

  A medically fine-tuned Llama-3.1-8B checkpoint (UltraMedical) scores below its general-purpose Instruct counterpart on both selecting the correct definition of medical jargon in EHR context and judging whether a term is jargon, and its errors are almost entirely false positives — it treats ordinary words in clinical text as specialized.

  On multiple-choice questions derived from industry cybersecurity certifications, frontier models reach human-expert level on general networking and IT security, but accuracy falls on vendor-specific material and formal standards, staying below 40% on the hardest ISA/IEC 62443 and Fortinet NSE questions; general security benchmarks such as MMLU Computer Security are saturated near 100% and no longer separate models.

  For target-price valuation of listed companies, a multimodal financial model given large-scale financial-corpus pre-training followed by institution-specific fine-tuning has lower mean absolute valuation error than a general model prompted zero-shot, a single-stage fine-tuned financial LLM, and an analyst-parameterized DCF spreadsheet.

Techniques

• Expose domain pre-trained models as one tool API and pick petooling
  Wraps heterogeneous domain pre-trained models as stateless feature-extraction endpoints with declarative input specs, and has a planner rank candidates from the dataset's modality, channel count, sampling rate and class balance before code
• Match the encoder's pre-training corpus to the target domaintraining
  Instead of transferring a general-domain-trained hallucination detector, fine-tune a domain-pretrained encoder on a small set of in-domain claim-evidence pairs.
• Reweight jargon-favoring components post-hoctraining
  Decompose output logits into per-attention-head and per-MLP direct contributions and learn scalar component weights on a training split, suppressing components that push toward the jargon label.
• Score the decision pathway, not just the outcomeprocess
  Extract guideline decision trees into reference step sequences, then score a model's generated pathway by LLM-judged step-level match aggregated with dynamic time warping against the reference.
• Two-stage financial domain adaptation: corpus pre-train, thetraining
  Pre-train the model on large-scale public financial corpora with a loss penalizing valuations inconsistent with disclosed metrics, then LoRA/prompt-tune on an institution's own investment memos and risk rules.
