+- **Developed by:** [https://www.tii.ae](https://www.tii.ae)
+- **Model type:** Causal decoder-only
+- **Architecture:** Hybrid Transformers + Mamba architecture
+- **Language(s) (NLP):** English
+- **License:** Falcon-LLM License
+# Training details
+For more details about the training protocol of this model, please refer to the [Falcon-H1 technical blogpost](https://falcon-lm.github.io/blog/falcon-h1/) and [Technical Report](https://arxiv.org/abs/2507.22448).
+# Usage
+Currently to use this model you can either rely on Hugging Face `transformers`, `vLLM` or `llama.cpp` library.
+## Inference
+Make sure to install the latest version of `transformers` or `vllm`, eventually install these packages from source:
+```bash
+pip install git+https://github.com/huggingface/transformers.git
+```
+For vLLM, make sure to install `vllm>=0.9.0`:
+```bash
+pip install "vllm>=0.9.0"
+```
+### 🤗 transformers
+Refer to the snippet below to run H1 models using 🤗 transformers:
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+model_id = "tiiuae/Falcon-H1-1B-Base"
+model = AutoModelForCausalLM.from_pretrained(
+  model_id,
+  torch_dtype=torch.bfloat16,
+  device_map="auto"
+)
+# Perform text generation
+```
+### vLLM
+For vLLM, simply start a server by executing the command below:
+```
+# pip install vllm>=0.9.0
+vllm serve tiiuae/Falcon-H1-1B-Instruct --tensor-parallel-size 2 --data-parallel-size 1
+```
+### `llama.cpp`
+You can find all GGUF files compatible with `llama.cpp` under [our official collection](https://huggingface.co/collections/tiiuae/falcon-h1-6819f2795bc406da60fab8df)
+# Evaluation
+Falcon-H1 series perform very well on a variety of tasks, including reasoning tasks.
