CRAZIEST AI story of the week.
Thomson Reuters just launched an LLM called Thomson.
It starts with Qwen3.5-397B, then is continually trained on 175 years of proprietary legal, tax, accounting, and news data.
They spent $40M on it.
Two years ago, Thomson Reuters bought a pre-revenue legal-AI startup called Safe Sign.
That team built Thomson.
On Thomson Reuters’ published benchmarks, they say it is comparable to Claude Opus 4.8 and ahead of GPT-5.5, Claude Sonnet 5, and Gemini 3.1 Pro overall.
They have used less than 10% of their data collection so far.
We’re going to see this a lot more often.
