4B Params BF16 Open Weights Inference Available

AesCoder-4B is a 4 billion parameter model developed by SamuelBang (Microsoft Research Asia, Shanghai Jiao Tong University, Peking University) specifically designed to enhance the aesthetic quality of LLM-generated code, particularly for webpage design. It was trained using the AesCode-358K dataset and an agentic reward feedback system, integrating executability, static, and interactive aesthetics. This model excels at generating visually appealing and functional web code, outperforming larger models like GPT-4o and GPT-4.1 on code aesthetics benchmarks.

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.
