McGill-NLP/delethink-24k-1.5b is a 1.5 billion parameter language model developed by McGill-NLP, initialized from DeepSeek-R1-Distill-Qwen-1.5B. It employs a novel Markovian Thinking (Delethink RL) paradigm for efficient long-form reasoning, allowing an effective thinking budget of approximately 24,000 tokens with only an 8,000 token active context. This model is specifically designed for math and logic reasoning tasks, generating step-by-step derivations with linear compute in thinking tokens.

Model tree for
McGill-NLP/delethink-24k-1.5bMost 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.
