Halluminate Department of Research (HDR) here! We'll see you at EMNLP 2026 in Budapest with an oral presentation of our DealTrace benchmark, by Alinа Hyk, at FinNLP-2026 workshop🎉 Deal analysis is one of the most demanding tasks an AI agent can take on. The agent has to read a long selling document against the Excel model behind it, rebuild the forecast, and defend an investment recommendation, and a mistake at any step can carry through to the final answer without being visible in it. DealTrace was built to make that visible; we evaluated six frontier models under different levels of scaffolding, from no guidance to a structured method with a critique pass, on real private equity and M&A deal packages. Every claim in the recommendation is traced to the step that produced it, so the benchmark shows where an analysis fails rather than only scoring the final answer. If you work on agentic evaluation or AI in finance, we are looking forward to connecting at the conference; reach out!

Tier C

Niche: a handful of models scored, or built by an RL vendor.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

How we got to tier C

Adoption: built by Halluminate. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
Confirmed: a line from its own site or paper places it.

A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
