+# Accessing the GPU marketplace with Vast.ai and dstack
+
+__With dstack 0.12.3, you can now use Vast.ai's GPU marketplace as a cloud provider.__
+
+`dstack` offers a developer-friendly CLI and API to train and deploy gen AI models across any
+cloud. It streamlines development and deployment, eliminating the need for cloud infrastructure setup.
+
+The cost of GPUs is often the most critical factor hindering development. To address this, we 
+integrated with [Vast.ai](https://vast.ai/), providing GPUs from the marketplace at a lower cost.
+
+<!-- more -->
+
+Vast.ai offers a variety of GPUs from independent hosts and data centers.
+By default, it suggests GPU instances based on their quality score. If you want to, you can set the maximum price.
+
+<div class="termy">
+
+```shell
+$ dstack run . --gpu 24GB --backend vastai --max-price 0.4
+
+ #  REGION            INSTANCE  RESOURCES                       PRICE

+Continue? [y/n]:
+```
+
+</div>
+
+You can use Vast.ai to [fine-tune](../../docs/guides/fine-tuning.md), and 
+[deploy](../../docs/guides/text-generation.md) models or
+launching [dev environments](../../docs/guides/dev-environments.md) (which are highly convenient for interactive coding with your favorite IDE).
+Additionally, you can use Vast.ai alongside other cloud providers, switching to it when needed.
+
+Configuring Vast.ai for use with `dstack` is very easy. Log into your [Vast AI](https://cloud.vast.ai/) account, click Account in the sidebar,
+and copy your API Key.
+
+Then, go ahead and configure the backend:
+
+<div editor-title="~/.dstack/server/config.yml">
+
+```yaml
+projects:
+- name: main
+  backends:
+  - type: vastai
+    creds:
+      type: api_key
+      api_key: d75789f22f1908e0527c78a283b523dd73051c8c7d05456516fc91e9d4efd8c5
+```
+
+</div>
+
+Now you can restart the server and proceed to using `dstack`'s CLI and API.
+
+If you've been seeking the simplest way to train and deploy generative AI models utilizing cost-effective cloud GPUs, be
+sure to give `dstack` with Vast.ai a try. 
+
+Lastly, take the time to check out the new preview versions of the [fine-tuning](../../docs/guides/fine-tuning.md) and 
+[text generation](../../docs/guides/text-generation.md) APIs.
