Someone: So, what really do you do all day?
Me: Well, I read. I read carefully, and then I write carefully. And if I'm careful enough, I help someone. When I can't help, it's hard. When I do, it feels really good. That's about it. That's law work. #lawwork

AI learning from Star Trek…

Context rot happens when LLMs get too much info leading to errors, hallucinations

Rewatching Voyager s6e9, where Seven started concocting a range of conspiracies, the Dr's diagnosis sounded familiar...

The show was always way ahead of its time🖖

If your firm’s AI doesn’t understand context, it doesn’t understand your work.

DeepJudge connects what your lawyers know - clauses, names, concepts, meaning - into one unified view.

Know what your firm knows → https://t.co/4pwpPbtmt1

“@thomsonreuters tested GPT‑4.1 with CoCounsel… they found the model to be highly reliable at maintaining context across sources and accurately identifying nuanced relationships between documents, such as conflicting clauses or additional supplementary context…”

Which CoCounsel skills have you found helpful for innocence work? The summarize and timeline tools are very helpful, but also compare documents, which allows us to understand differences and consistency across testimony. @MSemanchik @TheInnCenter #SYNERGY2024

There is a vast difference between using generic AI chatbots and a legal-specific tool like CoCounsel. @MSemanchik @TheInnCenter #SYNERGY2024

Exoneration is hard. For example, we were able to get 43 convictions reversed from 1999-present. The average time served under a wrongful conviction is 16 years, and we use tech to see how we can get that down to 10, 5, or less. @MSemanchik @TheInnCenter #SYNERGY2024

Don’t assume AI will assume—meaning, consider what your prompt is asking or instructing, what files you have given to the AI, what content is in those files, and what content is not in those files. Ken Lam, AI & prompting engineer at @thomsonreuters #SYNERGY2024
