Hugging Face Vinnnf/Thinkless-1.5B-RL-DeepScaleR is a 1.5 billion parameter language model developed by Gongfan Fang, Xinyin Ma, and Xinchao Wang. It is trained under a reinforcement learning paradigm using a Decoupled Group Relative Policy Optimization (DeGRPO) algorithm, enabling it to adaptively select between short-form and long-form reasoning. This model is optimized to reduce computational costs by minimizing unnecessary long-chain thinking, particularly excelling in mathematical and reasoning benchmarks like Minerva Algebra, MATH-500, and GSM8K.

Popular Sampler Settings
Most commonly used values from Featherless users
temperature
This setting influences the sampling randomness. Lower values make the model more deterministic; higher values introduce randomness. Zero is greedy sampling.
–
top_p
This setting controls the cumulative probability of considered top tokens. Must be in (0, 1]. Set to 1 to consider all tokens.
–
top_k
This limits the number of top tokens to consider. Set to -1 to consider all tokens.
–
frequency_penalty
This setting penalizes new tokens based on their frequency in the generated text. Values > 0 encourage new tokens; < 0 encourages repetition.
–
presence_penalty
This setting penalizes new tokens based on their presence in the generated text so far. Values > 0 encourage new tokens; < 0 encourages repetition.
–
repetition_penalty
This setting penalizes new tokens based on their appearance in the prompt and generated text. Values > 1 encourage new tokens; < 1 encourages repetition.
–
min_p
This setting representing the minimum probability for a token to be considered relative to the most likely token. Must be in [0, 1]. Set to 0 to disable.
