The research team at Tsinghua University has successfully developed the 'LongWriter' artificial intelligence system, which can generate coherent texts exceeding 10,000 words, paving new avenues for long-form writing and content creation. By constructing the 'LongWriter-6k' dataset, which includes 6,000 writing samples, the research team has increased the maximum output length of the AI model from approximately 2,000 words to over 10,000 words. This innovative achievement not only enhances the AI's performance in long text generation tasks but even surpasses larger-scale models.

The standout feature of OpenAI's new model gpt-4o-64k-output-alpha is its ability to output up to 64K tokens at once, making it suitable for generating rich and detailed content, catering to writing, programming, and complex data analysis needs. However, this functionality comes at a higher API cost, with a fee of $18 per million output tokens, compared to just $6 for input tokens per million. This pricing strategy aims to match high computational costs and encourage responsible use of this powerful tool. The model is designed for creativity and research fields.
