+# gpt-oss-20b-base
+⚠️ WARNING:  This model is not affiliated with or sanctioned in any way by OpenAI. Proceed with caution.
+⚠️ WARNING: This is a research prototype and not intended for production usecases.
+## About
+This model is an adapted version of the [GPT-OSS 20B](https://openai.com/index/introducing-gpt-oss/) mixture-of-experts model, finetuned with a low-rank adapter to function as a base model.
+Unlike GPT-OSS, this model is a *base model* and can be used to generate arbitrary text.
+`gpt-oss-20b-base` is a LoRA finetune of the original GPT-OSS 20B model. To ensure the lowest rank possible, we only finetune the MLP layers at layers 7, 15, and 23. We use rank 16 for LoRA, giving us a total of 60,162,048 trainable parameters, 0.3% of the original model's 20,974,919,232 parameters. We've merged it all back in though, so you can think of this model as a fully finetuned one -- this makes it more useful for
+## Usage
+```python
+# Load model directly
+from transformers import AutoModelForCausalLM, AutoTokenizer
+model = AutoModelForCausalLM.from_pretrained("jxm/gpt-oss-20b-base", torch_dtype="auto")
+tokenizer = AutoTokenizer.from_pretrained("jxm/gpt-oss-20b-base")
+model.to("cuda")
+sample_text = [
+    "Hello, how are you?",
+    "Why is the sky blue?",
+    "Where in the world is Carmen Sandiego?",
+    "Can you explain the theory of relativity?",
+    "google.com/",
+    "Twas brillig, and the slithy toves",
+]
+def generate(text: list[str], **kwargs) -> list[str]:
+    text = [tokenizer.bos_token + t for t in text]
+    tt = tokenizer(text, padding=True, padding_side="left", truncation=False, return_tensors="pt")
+    tt = tt.to("cuda")
+    outputs = model.generate(**tt, **kwargs)
+    return tokenizer.batch_decode(outputs)
+outputs = generate(sample_text, max_new_tokens=100)
+print('\n\n'.join(outputs))
+```
+## Chat template
+This model was trained without a chat template. It will not function as a base model if you use the chat template! To generate text, simple prepend the text with `tokenizer.bos_token` (`'<|startoftext|>'`) and tokenize without a template.
+(Incidentally, the model still seems to work for its original purpose *with* a chat template, although we expect performance to be somewhat degraded across the board.)
+## Examples
+Here are some examples I generated from some random prompts.

Please add me as a friend on Facebook so that I can continue reading your future articles, which I am sure you will write to cover more such important issues relating to all the |

When does the Winter Olympics start in 2022? What is the largest desert in the world? Which is the oldest country in the world? What is the capital of Canada?|
+| What is your favorite coding language? | Let me know in the comments. What do you need help "with online? Lets work "on it together! Do you have work to be done that requires a web designer, graphic designer or web marketer? I can help you out. If you have any questions, feel free to reach out in the comments or via private message |
+| Where in the world is Carmen Sandiego? | This game is really simple. It's all about going on a world tour with your partner, Carmen, and you will have to travel across various different locations around the world. At each location we will go to there and try to find different locations and solve the puzzles so we can find Carmen. We are going around the world searching for her. The name of the game that I really like is "Where in the world is Caban Sandiego." The game is very fun to play and we can use |
+| Why is the sky blue? | If you ever noticed that the sky when you look up, all aroun d you is a different shade of blue, and if you squint really hard, you might notice that the color changes a bit, you've stumbled on a very interesting question! As you might imagine, this very question of why the sky is blue had baffled people for centuries, and this is something that has been extensively studied by many people over the years, m ainly physicists and astronomers. When a physicist from Sweden named Anders |
+| Can you explain the theory of relativity? | The question here is: what does gravity look like in an accelerating car? That's a good question. Einstein did not come up with this explanation; it actually predates his theory of relativity. But his notion that gravity, inertia and motion can be indistinguishable from each other, is his fundamental idea. A few words: gravitation in a car? You may think how heavy you feel is gravity. And maybe in a car you'd have to brake or jump, you'd feel gravity change? No  |
