Merriam-Webster: Our NEW Large Language Model will be released on 11.18.25 (bsky.app)

Merriam‑Webster announced a new large language model (LLM) slated for release on November 18, 2025, via a post dated October 1, 2025. The announcement frames the product as a heavily interactive web application (JavaScript required), suggesting a web‑first, user‑interactive experience rather than a static HTML interface. Beyond the release date and delivery format, the post provides no architecture or size details. The move is notable for the AI/ML community because a long‑standing lexicographic authority entering the LLM space could shift expectations around factuality, provenance and language precision. If Merriam‑Webster leverages its dictionary, corpus and editorial expertise to fine‑tune or ground the model, it may improve definition accuracy, sense disambiguation, etymology handling and usage examples—areas where general LLMs often hallucinate. Conversely, it raises questions about dataset licensing, update cadence, evaluation benchmarks (lexical correctness, citation of sources), and potential product integrations (search, education, language tools). With technical specifics absent, practitioners should watch for release notes, API details, evaluation metrics and data‑provenance claims at launch to assess the model’s architecture, capabilities and trustworthiness.
