Final 10 Checkpoints

Checkpoints
Checkpoint 358	Checkpoint 353
Checkpoint 357	Checkpoint 352
Checkpoint 356	Checkpoint 351
Checkpoint 355	Checkpoint 350
Checkpoint 354	Checkpoint 349

• 360 checkpoints are available for download
• To downloading other checkpoints, change the branch from 'main' to the checkpoint you want (e.g. 'ckpt_000').
• This is completed on the 'Files and versions' tab (to the right of the Model Card).

🟠 Loading Amber

To load a specific checkpoint, simply pass a revision with a value between "ckpt_000" and "ckpt_358". If no revision is provided, it will load "ckpt_359", which is the final checkpoint.

from transformers import LlamaTokenizer, LlamaForCausalLM

tokenizer = LlamaTokenizer.from_pretrained("LLM360/Amber", revision="ckpt_356")
model = LlamaForCausalLM.from_pretrained("LLM360/Amber", revision="ckpt_356")

input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))

About LLM360

LLM360 is an initiative for comprehensive and fully open-sourced LLMs, where all training details, model checkpoints, intermediate results, and additional analyses are made available to the community. Our goal is to advance the field by inviting the community to deepen the understanding of LLMs together. As the first step of the project LLM360, we release all intermediate model checkpoints, our fully-prepared pre-training dataset, all source code and configurations, and training details. We are committed to continually pushing the boundaries of LLMs through this open-source effort.
