-# Benchmark
-
-Go benchmark tests that measure end-to-end performance of a running Ollama server. Run these tests to evaluate model inference performance on your hardware and measure the impact of code changes.
-
-## When to use
-
-Run these benchmarks when:
- Making changes to the model inference engine
- Modifying model loading/unloading logic
- Changing prompt processing or token generation code
- Implementing a new model architecture
- Testing performance across different hardware setups
-
-## Prerequisites
- Ollama server running locally with `ollama serve` on `127.0.0.1:11434`
-## Usage and Examples
-
->[!NOTE]
->All commands must be run from the root directory of the Ollama project.
-
-Basic syntax:
-```bash
-go test -bench=. ./benchmark/... -m $MODEL_NAME
-```
-
-Required flags:
- `-bench=.`: Run all benchmarks
- `-m`: Model name to benchmark
-
-Optional flags:
- `-count N`: Number of times to run the benchmark (useful for statistical analysis)
- `-timeout T`: Maximum time for the benchmark to run (e.g. "10m" for 10 minutes)
-
-Common usage patterns:
-
-Single benchmark run with a model specified:
-```bash
-go test -bench=. ./benchmark/... -m llama3.3
-```

-## Output metrics
-
-The benchmark reports several key metrics:
-
- `gen_tok/s`: Generated tokens per second
- `prompt_tok/s`: Prompt processing tokens per second
- `ttft_ms`: Time to first token in milliseconds
- `load_ms`: Model load time in milliseconds
- `gen_tokens`: Total tokens generated
- `prompt_tokens`: Total prompt tokens processed
-
-Each benchmark runs two scenarios:
- Cold start: Model is loaded from disk for each test
- Warm start: Model is pre-loaded in memory
-
-Three prompt lengths are tested for each scenario:
- Short prompt (100 tokens)
- Medium prompt (500 tokens)
- Long prompt (1000 tokens)

+
+## Cloud Models
+
+[Cloud models](https://ollama.com/cloud) are a new kind of model in Ollama that can run without a powerful GPU. Instead, cloud models are automatically offloaded to Ollama's cloud while offering the same capabilities as local models, making it possible to keep using your local tools while running larger models that wouldn’t fit on a personal computer.
+
+Ollama currently supports the following cloud models, with more coming soon:
+
+- `gpt-oss:20b-cloud`
+- `gpt-oss:120b-cloud`
+- `deepseek-v3.1:671b-cloud`
+- `qwen3-coder:480b-cloud`
+
+### Get started
+
+To run a cloud model, open the terminal and run:
+
+```
+ollama run gpt-oss:120b-cloud
+```
+
+To run cloud models with integrations that work with Ollama, first download the cloud model:
+
+```
+ollama pull qwen3-coder:480b-cloud
+```
+
+Then sign in to Ollama:
+
+```
+ollama signin
+```
+
+Finally, access the model using the model name `qwen3-coder:480b-cloud` via Ollama's local API or tooling.
+
+## Cloud API access
+
+Cloud models can also be accessed directly on ollama.com's API. For more information, see the [docs](https://docs.ollama.com/cloud).

-Ollama supports two levels of concurrent processing.  If your system has sufficient available memory (system memory when using CPU inference, or VRAM for GPU inference) then multiple models can be loaded at the same time.  For a given model, if there is sufficient available memory when the model is loaded, it is configured to allow parallel request processing.
+Ollama supports two levels of concurrent processing.  If your system has sufficient available memory (system memory when using CPU inference, or VRAM for GPU inference) then multiple models can be loaded at the same time.  For a given model, if there is sufficient available memory when the model is loaded, it can be configured to allow parallel request processing.

 If there is insufficient available memory to load a new model request while one or more models are already loaded, all new requests will be queued until the new model can be loaded.  As prior models become idle, one or more will be unloaded to make room for the new model.  Queued requests will be processed in order.  When using GPU inference new models must be able to completely fit in VRAM to allow concurrent model loads.

 The following server settings may be used to adjust how Ollama handles concurrent requests on most platforms:

 - `OLLAMA_MAX_LOADED_MODELS` - The maximum number of models that can be loaded concurrently provided they fit in available memory.  The default is 3 * the number of GPUs or 3 for CPU inference.
- `OLLAMA_NUM_PARALLEL` - The maximum number of parallel requests each model will process at the same time.  The default will auto-select either 4 or 1 based on available memory.
+- `OLLAMA_NUM_PARALLEL` - The maximum number of parallel requests each model will process at the same time.  The default is 1, and will handle 1 request per model at a time.
 - `OLLAMA_MAX_QUEUE` - The maximum number of requests Ollama will queue when busy before rejecting additional requests. The default is 512

 Note: Windows with Radeon GPUs currently default to 1 model maximum due to limitations in ROCm v5.7 for available VRAM reporting.  Once ROCm v6.2 is available, Windows Radeon will follow the defaults above.

+# Ollama for macOS
+
+## System Requirements
+
+* MacOS Sonoma (v14) or newer
+* Apple M series (CPU and GPU support) or x86 (CPU only)
+
+
+## Filesystem Requirements
+
+The preferred method of installation is to mount the `ollama.dmg` and drag-and-drop the Ollama application to the system-wide `Applications` folder.  Upon startup, the Ollama app will verify the `ollama` CLI is present in your PATH, and if not detected, will prompt for permission to create a link in `/usr/local/bin`
+
+Once you've installed Ollama, you'll need additional space for storing the Large Language models, which can be tens to hundreds of GB in size.  If your home directory doesn't have enough space, you can change where the binaries are installed, and where the models are stored.
+
+### Changing Install Location
+
+To install the Ollama application somewhere other than `Applications`, place the Ollama application in the desired location, and ensure the CLI `Ollama.app/Contents/Resources/ollama` or a sym-link to the CLI can be found in your path.  Upon first start decline the "Move to Applications?" request.
+
+
+## Troubleshooting
+
+Ollama on MacOS stores files in a few different locations.
+- `~/.ollama` contains models and configuration
+- `~/.ollama/logs` contains logs
+    - *app.log* contains most recent logs from the GUI application
+    - *server.log* contains the most recent server logs
+- `<install location>/Ollama.app/Contents/Resources/ollama` the CLI binary
+
+## Uninstall
+
+To fully remove Ollama from your system, remove the following files and folders:
+
+```
+sudo rm -rf /Applications/Ollama.app
+sudo rm /usr/local/bin/ollama
+rm -rf "~/Library/Application Support/Ollama"
+rm -rf "~/Library/Saved Application State/com.electron.ollama.savedState"
+rm -rf ~/Library/Caches/com.electron.ollama/
+rm -rf ~/Library/Caches/ollama

-Ollama includes multiple LLM libraries compiled for different GPUs and CPU vector features. Ollama tries to pick the best one based on the capabilities of your system. If this autodetection has problems, or you run into other problems (e.g. crashes in your GPU) you can workaround this by forcing a specific LLM library. `cpu_avx2` will perform the best, followed by `cpu_avx` an the slowest but most compatible is `cpu`.

Use `ls -lnd /dev/kfd /dev/dri /dev/dri/*` on the host system to determine the **numeric** group IDs on your system, and pass additional `--group-add ...` arguments to the container so it can access the required devices.   For example, in the following output `crw-rw---- 1 0  44 226,   0 Sep 16 16:55 /dev/dri/card0` the group ID column is `44`

 If you are experiencing problems getting Ollama to correctly discover or use your GPU for inference, the following may help isolate the failure.

+By default, these tests are disabled so `go test ./...` will exercise only unit tests.  To run integration tests you must pass the integration tag.  `go test -tags=integration ./...` Some tests require additional tags to enable to allow scoped testing to keep the duration reasonable.  For example, testing a broad set of models requires `-tags=integration,models` and a longer timeout (~60m or more depending on the speed of your GPU.). To view the current set of tag combinations use `find integration -type f | xargs grep "go:build"`


 The integration tests have 2 modes of operating.

 1. By default, they will start the server on a random port, run the tests, and then shutdown the server.
-2. If `OLLAMA_TEST_EXISTING` is set to a non-empty string, the tests will run against an existing running server, which can be remote
+2. If `OLLAMA_TEST_EXISTING` is set to a non-empty string, the tests will run against an existing running server, which can be remote based on your `OLLAMA_HOST` environment variable
+
+> [!IMPORTANT]
+> Before running the tests locally without the "test existing" setting, compile ollama from the top of the source tree  `go build .` in addition to GPU support with cmake if applicable on your platform.  The integration tests expect to find an ollama binary at the top of the tree.
+
+
+Many tests use a default small model suitable to run on many systems.  You can override this default model by setting `OLLAMA_TEST_DEFAULT_MODEL`
