# FrontiersMind: lumma-fev

> FrontiersMind's decision model on a base it pre-trained from scratch. Each question reads the state and its own tokens once and a 256-dimension pointer head scores the options; Choice and Score take up to 255 entries, and nothing is generated.

# Lumma-Fev-0.6B

FrontiersMind's decision model on a base it pre-trained from scratch. Each question reads the state and its own tokens once and a 256-dimension pointer head scores the options; Choice and Score take up to 255 entries, and nothing is generated.

A merged rank-16 LoRA on Lumma-0.6B-Base, for English and ten Indian languages, with a pip package (lumma-fev) and a /v1/systemone server. The maker's table gives 0.64 on typed-decisions, 0.84 on AG News and 0.90 on Banking77 for this size, and 0.78 and 0.81 on typed-decisions for Lumma-Fev-4B and 9B (released 25 September; their cards do not name a base). The table does not say which split or hardware was used. The third-party Decision Index 0.2.1 gives the 0.6B a balanced score of 2.97, so treat the maker's figures as unconfirmed.

## What it decides

- **choice** — picks one option from a set
- **score** — places the input on an ordered scale
- **noul** — answers a yes/no question with one calibrated probability
