Preference for Older Language Models in Technical Writing

Summary: New language models (like Qwen3.8 27B and DeepSeek V4 Flash) are noted to have a Claude-like writing style. This style is reportedly found unsuitable for technical writing.

This news focuses on the stylistic characteristics of texts generated by large language models (LLMs) and user preferences. The observation that newer models have a specific “Claude-sounding” writing style is a result of the model’s training data and fine-tuning processes. In technical writing, there is a high expectation for clarity, accuracy, and an understated language.

The output style of LLMs is shaped by the model’s architecture, the diversity of its training dataset, and the prompts and reward models used during fine-tuning. If a model adopts a particular “artificial” or “exaggerated” tone, it might imply that such outputs were rewarded during the model’s training. For technical writing, a more direct and information-focused style is preferred.

For engineers using LLMs in live systems or documentation processes, it is crucial that the model’s output style meets business requirements. If a model produces an undesirable tone or style, it might necessitate additional post-processing steps or the selection of a different model. This indicates that not only performance metrics but also output quality are important in model selection.

Engineers should carefully evaluate the output of LLMs when using them for technical documentation or communication and, if necessary, try to achieve the desired style through fine-tuning or prompt engineering. It is beneficial to consider that different models might be more suitable for different use cases.
