Downstream

Feel free to create and share your work built using Yi series models. Share your models and insights with the Yi community to contribute to the growth of this innovative project.

Serving

Yi offers various services built upon its models, such as Yi-34B-Chat and Yi-6B-Chat, allowing you to interact with the models easily. These services are designed to make it straightforward for you to get started with Yi.

Quantitation

Yi provides quantized models with reduced precision, offering increased efficiency, faster inference speed, and smaller RAM usage. This makes it accessible to a wider range of users, even those with limited computational capabilities.

Fine-tuning

Explore Yi's fine-tuned models hosted by TheBloke and other contributors. These models have been fine-tuned for various specific tasks and applications, expanding the versatility of Yi in real-world scenarios.

Benchmarks

Yi has been extensively benchmarked to evaluate its performance. These benchmarks include both base model and chat model performance in various language tasks, such as common sense reasoning, reading comprehension, and more.

Base Model Performance

Benchmark results show the capabilities of Yi's base models in tasks ranging from common sense reasoning to reading comprehension and math and code-related tasks. Yi-34B, for example, demonstrates impressive performance in multiple categories.

Chat Model Performance

Yi-6B-Chat and Yi-34B-Chat have been evaluated for their performance in chat-related tasks, showcasing their ability to handle zero-shot and few-shot scenarios effectively.

Quantized Chat Model Performance

Quantized versions of Yi-6B-Chat and Yi-34B-Chat have also been evaluated, demonstrating negligible losses in performance while offering increased efficiency.

Limitations of Chat Model

While Yi chat models offer diverse and creative responses, there are limitations to consider. These limitations include the potential for hallucination (producing incorrect information), non-determinism in re-generation (inconsistent outcomes), and cumulative error (small inaccuracies compounding over time). Adjusting generation configuration parameters can help mitigate these issues.

Who Can Use Yi?

The Yi series models are available for everyone, including:

• Personal usage
• Academic purposes
• Commercial use (with the appropriate license)

To use Yi for free commercial purposes, you need to complete a simple application process to obtain a Yi Model Commercial License.
