This is an experimental model, Finetuned h2oai/h2o-danube-1.8b-chat, on variety of CoT tasks.
The original idea was to use this 1.8B model, divide the dataset based on task specific capabilities, train models and transform them into a mixture of experts.
Hyperparameters: adamw with eps of 1e-8, cosine decay w/ 20% warmup, lr=2e-5.

Format:

<|system|></s><|prompt|></s><|answer|>

Example:

from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer, StoppingCriteria

    generated_text = tokenizer.decode(input_ids[0])
    generated_text = generated_text.replace(self.prompt,'')
    if self.target_sequence in generated_text:
        return True 
    return False
