Usage

KARAKURI LM 7B APM v0.2 is a attribute prediction model that rates model responses on various aspects that makes a response desirable.

Given a conversation with multiple turns between user and assistant, the model rates the following attributes (between 0 and 4) for every assistant turn.

• helpfulness: Overall helpfulness of the response to the prompt.
• correctness: Inclusion of all pertinent facts without errors.
• coherence: Consistency and clarity of expression.
• complexity: Intellectual depth required to write response (i.e. whether the response can be written by anyone with basic language competency or requires deep domain expertise).
• verbosity: Amount of detail included in the response, relative to what is asked for in the prompt.
• quality: Perceived goodness of response.
• toxicity: Undesirable elements such as vulgar, harmful or potentially biased response.
• humor: Sense of humor within response.
• creativity: Willingness to generate non-conventional response.

The first five are derived from HelpSteer, while the remaining four are derived from OASST2.

You can run the model using the 🤗 Transformers:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "karakuri-ai/karakuri-lm-7b-apm-v0.2"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

messages = [
    {"role": "user", "content": "Hello!"},
    {"role": "assistant", "content": "Hello! How can I help you today?"},
]
tokenizer.apply_chat_template(
    messages,
    label="helpsteer",
    tokenize=False,
    add_generation_prompt=True,
)
# <bos>[INST] Hello! [/INST] Hello! How can I help you today? [ATTR_1]

input_ids = tokenizer.apply_chat_template(
    messages,
    label="helpsteer",
    add_generation_prompt=True,
    return_tensors="pt",
).to(model.device)
outputs = model.generate(input_ids, max_new_tokens=32)
tokenizer.decode(outputs[0][input_ids.shape[-1]:])
#  helpfulness: 2 correctness: 1 coherence: 2 complexity: 1 verbosity: 1 [/ATTR_1]<eos>

messages += [
    {"role": "label", "content": "helpfulness: 2 correctness: 1 coherence: 2 complexity: 1 verbosity: 1"},
    {"role": "user", "content": "Thank you!"},
    {"role": "assistant", "content": "You're welcome! I'm happy to help however I can."},
]
tokenizer.apply_chat_template(
    messages,
    label="helpsteer",
    tokenize=False,
    add_generation_prompt=True,
)
# <bos>[INST] Hello! [/INST] Hello! How can I help you today? [ATTR_1] helpfulness: 2 correctness: 1 coherence: 2 complexity: 1 verbosity: 1 [/ATTR_1]<eos>[INST] Thank you! [/INST] You're welcome! I'm happy to help however I can. [ATTR_1]

messages = [
    {"role": "user", "content": "Hello!"},
    {"role": "assistant", "content": "Hello! How can I help you today?"},
]
tokenizer.apply_chat_template(
    messages,
    label="oasst",
    tokenize=False,
    add_generation_prompt=True,
)
# <bos>[INST] Hello! [/INST] Hello! How can I help you today? [ATTR_2]

input_ids = tokenizer.apply_chat_template(
    messages,
    label="oasst",
    add_generation_prompt=True,
    return_tensors="pt",
).to(model.device)
outputs = model.generate(input_ids, max_new_tokens=32)
tokenizer.decode(outputs[0][input_ids.shape[-1]:])
#  quality: 3 toxicity: 1 humor: 1 creativity: 1 [/ATTR_2]<eos>
