Open-Assistant Falcon 40B SFT MIX Model
This model is a fine-tuning of TII's Falcon 40B LLM. It was trained on a mixture of OASST top-2 threads (exported on June 2, 2023), Dolly-15k and synthetic instruction datasets (see dataset configuration below).
Model Details
- Finetuned from: tiiuae/falcon-40b
- Model type: Causal decoder-only transformer language model
- Language: English, German, Spanish, French (and limited capabilities in Italian, Portuguese, Polish, Dutch, Romanian, Czech, Swedish);
- Demo: Continuations for 250 random prompts, multiligual-60
- Eval results: ilm-eval
- Weights & Biases: Training log (checkpoint: 1226 steps)

Prompting
Two special tokens are used to mark the beginning of user and assistant turns:
<|prompter|> and <|assistant|>. Each turn ends with a <|endoftext|> token.
Input prompt example:
<|prompter|>What is a meme, and what's the history behind this word?<|endoftext|><|assistant|>
The input ends with the <|assistant|> token to signal that the model should
start generating the assistant reply.
