## Bias
Field | Response
:---------------------------------------------------------------------------------------------------|:---------------
Participation considerations from adversely impacted groups [protected classes](https://www.senate.ca.gov/content/protected-classes) in model design and testing: | None
Measures taken to mitigate against unwanted bias: | None
## Explainability
Field | Response
:------------------------------------------------------------------------------------------------------|:---------------------------------------------------------------------------------
Intended Application & Domain: | Response Customization in Large Language Model Development
Model Type: | Text-to-Text Transformer
Intended User: | Developers customizing model response across different applications and domains.
Output: | List of floats
Describe how the model works: | Generates a reward score based on conversation.
Name the adversely impacted groups this has been tested to deliver comparable outcomes regardless of: | Not Applicable
Verified to have met prescribed quality standards: | Yes
Technical Limitations: | This model may not work for non-English languages.
Performance Metrics: | Throughput and Latency
Potential Known Risks: | The Model may produce output that is biased and toxic based on how it is prompted, producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive. The model may also amplify biases and return toxic responses especially when prompted with toxic prompts.
