+## Ollama
+
+###  Models
+Ollama stores models in an OCI registry which by default are stored in
+~/.ollama/models.
+
+### Using a local model
+I wanted to run a gguf model that I have locally and this can be done by running
+the following commands:
+
+Make sure the ollama REST server is running
+```console
+$ cd ~/work/ai/ollama
+$ ./ollama serve
+```
+
+Create a configuration file that describes the model:
+```console
+FROM /home/danbev/.ollama/models/llama-2-7b-hf-chat-q4.gguf
+
+LICENSE apache-2.0
+
+# Adjust the parameters based on your needs
+PARAMETER stop "Human:"
+PARAMETER stop "Assistant:"
+PARAMETER temperature 0.7
+PARAMETER top_k 40
+PARAMETER top_p 0.5
+```
+
+Create the model in using the above configuration file (saved as ModelFile):
+```console
+$ ./ollama create mycustomllama -f Modelfile
+```
+Run the model:
+```console
+$ ./ollama run mycustomllama
+```
+
+### Inspecting a model
+If a gguf model is used we can find the blob for the model by either inspecting
+the metadata file:
+```console
+$ cat ~/.ollama/models/manifests/registry.ollama.ai/library/mycustomllama/latest | jq '.layers[] | select(.mediaType == "application/vnd.ollama.image.model") | .digest'
+"sha256:42f685711f23fc73c4558da0d8df22fd18ecabbee9c6c8f8277204902ace10d3"
+```
+And we can use the digest (without the sha256: prefix) to find the blob:
+```console
+$ ./inspect-model.sh ~/.ollama/models/blobs/sha256-42f685711f23fc73c4558da0d8df22fd18ecabbee9c6c8f8277204902ace10d3
+INFO:gguf-dump:* Loading: /home/danbev/.ollama/models/blobs/sha256-42f685711f23fc73c4558da0d8df22fd18ecabbee9c6c8f8277204902ace10d3
+* File is LITTLE endian, script is running on a LITTLE endian host.
+* Dumping 35 key/value pair(s)
+      1: UINT32     |        1 | GGUF.version = 3
+      2: UINT64     |        1 | GGUF.tensor_count = 291
+      3: UINT64     |        1 | GGUF.kv_count = 32
+      4: STRING     |        1 | general.architecture = 'llama'
+```
+
+The blob is also shows in the servers console:
+```console
+llama_model_loader: loaded meta data with 32 key-value pairs and 291 tensors from /home/danbev/.ollama/models/blobs/sha256-42f685711f23fc73c4558da0d8df22fd18ecabbee9c6c8f8277204902ace10d3 (version GGUF V3 (latest))
+```
+
+### Building from source
+```console
+$ cd ~/work/ai/ollama
+$ make -j 8
+$ go build .
