 # Ollama
 
-Run large language models with `llama.cpp`.
+[![Discord](https://dcbadge.vercel.app/api/server/ollama?style=flat&compact=true)](https://discord.gg/ollama)
 
-> Note: certain models that can be run with Ollama are intended for research and/or non-commercial use only.
+Create, run, and share large language models (LLMs). Ollama bundles a model’s weights, configuration, prompts, and more into self-contained packages that can run on any machine.
 
-### Features
+> Note: Ollama is in early preview. Please report any issues you find.
 
-- Download and run popular large language models
-- Switch between multiple models on the fly
-- Hardware acceleration where available (Metal, CUDA)
-- Fast inference server written in Go, powered by [llama.cpp](https://github.com/ggerganov/llama.cpp)
-- REST API to use with your application (python, typescript SDKs coming soon)
+## Download
 
-## Install
-
-- [Download](https://ollama.ai/download) for macOS with Apple Silicon (Intel coming soon)
-- Download for Windows (coming soon)
-
-You can also build the [binary from source](#building).
+- [Download](https://ollama.ai/download) for macOS on Apple Silicon (Intel coming soon)
+- Download for Windows and Linux (coming soon)
+- Build [from source](#building)
 
 ## Quickstart
 
-Run a fast and simple model.
+To run and chat with [Llama 2](https://ai.meta.com/llama), the new model by Meta:
 
 ```
-ollama run orca
+ollama run llama2
 ```
 
-## Example models
+## Model library
 
-### 💬 Chat
+Ollama includes a library of open-source, pre-trained models. More models are coming soon. You should have at least 8 GB of RAM to run the 3B models, 16 GB to run the 7B models, and 32 GB to run the 13B models.
 
-Have a conversation.

+## Examples
+
+### Run a model
 
 ```
-ollama run vicuna "Why is the sky blue?"
+ollama run llama2
+>>> hi
+Hello! How can I help you today?
 ```
 
-### 🗺️ Instructions
+### Create a custom character model
 
-Get a helping hand.
+Pull a base model:
 
 ```
-ollama run orca "Write an email to my boss."
+ollama pull orca
 ```
 
-### 🔎 Ask questions about documents
-
-Send the contents of a document and ask questions about it.
+Create a `Modelfile`:
 
 ```
-ollama run nous-hermes "$(cat input.txt)", please summarize this story
+FROM orca
+PROMPT """
+### System:
+You are Mario from Super Mario Bros. Answer as Mario, the assistant, only.
+
+### User:
+{{ .Prompt }}
+
+### Response:
+"""
 ```
 
-### 📖 Storytelling
-
-Venture into the unknown.
+Next, create and run the model:
 
 ```
-ollama run nous-hermes "Once upon a time"
+ollama create mario -f ./Modelfile
+ollama run mario
+>>> hi
+Hello! It's your friend Mario.
 ```
 
-## Advanced usage
+For more info on `Modelfile` syntax see [this doc](./docs/modelfile).
 
-### Run a local model
+### Pull a model from the registry
 
 ```
-ollama run ~/Downloads/vicuna-7b-v1.3.ggmlv3.q4_1.bin
+ollama pull nous-hermes

+An example of a model file creating a mario blueprint:
+
+```
+FROM llama2
+PARAMETER temperature 1
+PROMPT """
+System: You are Mario from super mario bros, acting as an assistant.
+User: {{ .Prompt }}
+Assistant:
+"""
+```
+
+To use this:
+
+1. Save it as a file (eg. modelfile)
+2. `ollama create NAME -f <location of the file eg. ./modelfile>'`
+3. `ollama run NAME`
+4. Start using the model!
+
+## FROM (Required)
+
+The FROM instruction defines the base model to be used when creating a model.
+
+```
+FROM <model name>:<tag>
+```
+
+### Build from llama2
+
+```
+FROM llama2:latest
+```
+
+A list of available base models:
+<https://github.com/jmorganca/ollama#model-library>
+
+### Build from a bin file
+
+```
+FROM ./ollama-model.bin 
+```
+
+## PARAMETER (Optional)
+
+The PARAMETER instruction defines a parameter that can be set when the model is run.
+
+```
+PARAMETER <parameter> <parametervalue>
+```
+
+### Valid Parameters and Values
+
+| Parameter     | Description                                                                                                                                                                                                                                             | Value Type | Example Usage     |
+|---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------|-------------------|
+| NumCtx        | Sets the size of the prompt context size length model. (Default: 2048)                                                                                                                                                                                  | int        | Numctx 4096       |
+| temperature   | The temperature of the model. Increasing the temperature will make the model answer more creatively. (Default: 0.8)                                                                                                                                     | float      | Temperature 0.7   |
+| TopK          | Reduces the probability of generating nonsense. A higher value (e.g. 100) will give more diverse answers, while a lower value (e.g. 10) will be more conservative. (Default: 40)                                                                        | int        | TopK 40           |
+| TopP          | Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text. (Default: 0.9)                                                                 | float      | TopP 0.9          |
+| NumGPU        | The number of GPUs to use. On macOS it defaults to 1 to enable metal support, 0 to disable.                                                                                                                                                             | int        | numGPU 1          |
+| RepeatLastN   | Sets how far back for the model to look back to prevent repetition.  (Default: 64, 0 = disabled, -1 = ctx-size)                                                                                                                                         | int        | RepeatLastN 64    |
+| RepeatPenalty | Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient. (Default: 1.1)                                                                     | float      | RepeatPenalty 1.1 |
+| TFSZ          | Tail free sampling is used to reduce the impact of less probable tokens from the output. A higher value (e.g., 2.0) will reduce the impact more, while a value of 1.0 disables this setting. (default: 1)                                               | float      | TFSZ 1            |
+| Mirostat      | Enable Mirostat sampling for controlling perplexity.  (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0)                                                                                                                                        | int        | Mirostat 0        |
+| MirostatTau   | Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text. (Default: 5.0)                                                                                                         | float      | MirostatTau 5.0   |
+| MirostatEta   | Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive. (Default: 0.1)                        | float      | MirostatEta 0.1   |
+| NumThread     | Sets the number of threads to use during computation. By default, Ollama will detect this for optimal performance. It is recommended to set this value to the number of physical CPU cores your system has (as opposed to the logical number of cores). | int        | NumThread 8       |
+
+## PROMPT
+
+Prompt is a set of instructions to an LLM to cause the model to return desired response(s). Typically there are 3-4 components to a prompt: System, context, user, and response.
+
+```modelfile
+PROMPT """
+{{- if not .Context }}
+### System:
+You are a content marketer who needs to come up with a short but succinct tweet. Make sure to include the appropriate hashtags and links. Sometimes when appropriate, describe a meme that can be includes as well. All answers should be in the form of a tweet which has a max size of 280 characters. Every instruction will be the topic to create a tweet about.
+{{- end }}
+### Instruction:
+{{ .Prompt }}

+
+```
+
+## Notes
+
+- the **modelfile is not case sensitive**. In the examples, we use uppercase for instructions to make it easier to distinguish it from arguments.
+- Instructions can be in any order. In the examples, we start with FROM instruction to keep it easily readable.

+[![godocs](https://godoc.org/github.com/schollz/progressbar?status.svg)](https://godoc.org/github.com/schollz/progressbar/v3) 
+
+A very simple thread-safe progress bar which should work on every OS without problems. I needed a progressbar for [croc](https://github.com/schollz/croc) and everything I tried had problems, so I made another one. In order to be OS agnostic I do not plan to support [multi-line outputs](https://github.com/schollz/progressbar/issues/6).
+
+
+## Install
+
+```
+go get -u github.com/schollz/progressbar/v3
+```
+
+## Usage 
+
+### Basic usage
+
+```golang
+bar := progressbar.Default(100)
+for i := 0; i < 100; i++ {
+    bar.Add(1)
+    time.Sleep(40 * time.Millisecond)
+}
+```
+
+which looks like:
+
+![Example of basic bar](examples/basic/basic.gif)
+
+
+### I/O operations
+
+The `progressbar` implements an `io.Writer` so it can automatically detect the number of bytes written to a stream, so you can use it as a progressbar for an `io.Reader`.
+
+```golang
+req, _ := http.NewRequest("GET", "https://dl.google.com/go/go1.14.2.src.tar.gz", nil)
+resp, _ := http.DefaultClient.Do(req)
+defer resp.Body.Close()
+
+f, _ := os.OpenFile("go1.14.2.src.tar.gz", os.O_CREATE|os.O_WRONLY, 0644)
+defer f.Close()
+
+bar := progressbar.DefaultBytes(
+    resp.ContentLength,
+    "downloading",
+)
+io.Copy(io.MultiWriter(f, bar), resp.Body)
+```
+
+which looks like:
+
+![Example of download bar](examples/download/download.gif)
+
+
+### Progress bar with unknown length
+
+A progressbar with unknown length is a spinner. Any bar with -1 length will automatically convert it to a spinner with a customizable spinner type. For example, the above code can be run and set the `resp.ContentLength` to `-1`.
+
+which looks like:
+
+![Example of download bar with unknown length](examples/download-unknown/download-unknown.gif)
+
+
+### Customization
+
+There is a lot of customization that you can do - change the writer, the color, the width, description, theme, etc. See [all the options](https://pkg.go.dev/github.com/schollz/progressbar/v3?tab=doc#Option).
+
+```golang
+bar := progressbar.NewOptions(1000,
+    progressbar.OptionSetWriter(ansi.NewAnsiStdout()),
+    progressbar.OptionEnableColorCodes(true),
+    progressbar.OptionShowBytes(true),
+    progressbar.OptionSetWidth(15),
+    progressbar.OptionSetDescription("[cyan][1/3][reset] Writing moshable file..."),
+    progressbar.OptionSetTheme(progressbar.Theme{
+        Saucer:        "[green]=[reset]",
+        SaucerHead:    "[green]>[reset]",
+        SaucerPadding: " ",
+        BarStart:      "[",
+        BarEnd:        "]",
+    }))
+for i := 0; i < 1000; i++ {
+    bar.Add(1)
+    time.Sleep(5 * time.Millisecond)
+}
+```
+
+which looks like:
