Thomson Reuters bets $40M on owning its AI instead of renting from OpenAI or Anthropic

Thomson Reuters is investing $40 million over two years to develop Thomson, an internal language model based on Alibaba's Qwen architecture. By moving away from third-party providers like OpenAI and Anthropic, the company aims to retain control over its proprietary data, specifically for integration with legal tools like Westlaw. This transition highlights a broader shift among major enterprises to prioritize private, specialized AI infrastructure over general-purpose models to better protect intellectual property and improve domain-specific performance.
