Talkie vs Tavily

Talkie is a 13-billion parameter language model trained exclusively on English-language texts published before 1931 — the largest vintage language model built to date. Created by researchers Nick Levine, David Duvenaud (University of Toronto), and Alec Radford (of GPT and DALL-E fame), it represents a novel approach to understanding what training data really does to a model. The research insight is elegant: modern LLMs are so thoroughly contaminated by modern internet data (directly or through distillation) that it's nearly impossible to isolate what the model "knows" from what it absorbed during training. Talkie solves this by hard-cutting the training corpus at 1931 — predating digital computers entirely. This lets the team run controlled experiments impossible with contemporary models, such as teaching the model to write Python from examples alone and measuring how quickly it generalizes. Talkie was trained on ~260 billion tokens of historical text and fine-tuned using direct preference optimization with Claude as judge on structured historical documents (etiquette manuals, letter-writing guides). It's openly available on Hugging Face for research use. It also happens to produce wonderfully formal, slightly anachronistic prose.

Tavily provides a search API designed for LLMs and AI agents with clean content extraction, source citations, and relevance ranking. Used in LangChain and other frameworks.
