stepfun-ai/Step-3.5-Flash
Step 3.5 Flash by stepfun-ai is a 196.81 billion parameter sparse Mixture-of-Experts (MoE) model, activating approximately 11 billion parameters per token. It features a 256K context window and is engineered for frontier reasoning and agentic capabilities with exceptional efficiency. The model excels in coding and complex, multi-step reasoning tasks, achieving high throughput for real-time interaction and robust performance on benchmarks like SWE-bench Verified and Terminal-Bench 2.0.
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.
