+# Llama
+
+[Llama](https://huggingface.co/papers/2302.13971) is a family of large language models ranging from 7B to 65B parameters. These models are focused on efficient inference (important for serving language models) by training a smaller model on more tokens rather than training a larger model on fewer tokens. The Llama model is based on the GPT architecture, but it uses pre-normalization to improve training stability, replaces ReLU with SwiGLU to improve performance, and replaces absolute positional embeddings with rotary positional embeddings (RoPE) to better handle longer sequence lengths.
+
+You can find all the original Llama checkpoints under the [Huggy Llama](https://huggingface.co/huggyllama) organization.
+
+> [!TIP]
+> Click on the Llama models in the right sidebar for more examples of how to apply Llama to different language tasks.
+
+The example below demonstrates how to generate text with [`Pipeline`] or the [`AutoModel`], and from the command line.
+
+<hfoptions id="usage">
+<hfoption id="Pipeline">
+
+```python
+from transformers import pipeline
+
+
+pipeline = pipeline(
+    task="text-generation",
+    model="huggyllama/llama-7b",
+    device=0
+)
+pipeline("Plants create energy through a process known as")
+```
+
+</hfoption>
+<hfoption id="AutoModel">
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+
+tokenizer = AutoTokenizer.from_pretrained(
+    "huggyllama/llama-7b",
+)
+model = AutoModelForCausalLM.from_pretrained(
+    "huggyllama/llama-7b",
+    device_map="auto",
+    attn_implementation="sdpa"
+)
+input_ids = tokenizer("Plants create energy through a process known as", return_tensors="pt").to(model.device)
+
+output = model.generate(**input_ids, cache_implementation="static")
+print(tokenizer.decode(output[0], skip_special_tokens=True))
+```
+
+</hfoption>
+</hfoptions>
+
+Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
+
+The example below uses [torchao](../quantization/torchao) to only quantize the weights to int4.
+
+```python
+# pip install torchao
+from transformers import AutoModelForCausalLM, AutoTokenizer, TorchAoConfig
+
+
+quantization_config = TorchAoConfig("int4_weight_only", group_size=128)
+model = AutoModelForCausalLM.from_pretrained(
+    "huggyllama/llama-30b",
+    device_map="auto",
+    quantization_config=quantization_config
+)
+
+tokenizer = AutoTokenizer.from_pretrained("huggyllama/llama-30b")
+input_ids = tokenizer("Plants create energy through a process known as", return_tensors="pt").to(model.device)
+
+output = model.generate(**input_ids, cache_implementation="static")
+print(tokenizer.decode(output[0], skip_special_tokens=True))
+```
+
+Use the [AttentionMaskVisualizer](https://github.com/huggingface/transformers/blob/beb9b5b02246b9b7ee81ddf938f93f44cfeaad19/src/transformers/utils/attention_visualizer.py#L139) to better understand what tokens the model can and cannot attend to.
+
+```python
+from transformers.utils.attention_visualizer import AttentionMaskVisualizer
+
+
+visualizer = AttentionMaskVisualizer("huggyllama/llama-7b")
+visualizer("Plants create energy through a process known as")
+```

+
+## Notes
+
+- The tokenizer is a byte-pair encoding model based on [SentencePiece](https://github.com/google/sentencepiece). During decoding, if the first token is the start of the word (for example, "Banana"), the tokenizer doesn't prepend the prefix space to the string.
