 Tests use pytest-asyncio with `asyncio_mode = "auto"`. Tests are in `tests/` subdirectories alongside the code they test. The `EXO_TESTS=1` env var is set during tests.

-## Dashboard UI Testing & Screenshots
-
-### Building and Running the Dashboard
-```bash
-# Build the dashboard (must be done before running exo)
-cd dashboard && npm install && npm run build && cd ..
-
-# Start exo (serves the dashboard at http://localhost:52415)
-uv run exo &

-### Taking Headless Screenshots with Playwright
-Use Playwright with headless Chromium for programmatic screenshots — no manual browser interaction needed.
-
-**Setup (one-time):**
-```bash
-npx --yes playwright install chromium
-cd /tmp && npm init -y && npm install playwright
-```
-
-**Taking screenshots:**
-```javascript
-// Run from /tmp where playwright is installed: cd /tmp && node -e "..."
-const { chromium } = require('playwright');
-(async () => {
-  const browser = await chromium.launch({ headless: true });
-  const page = await browser.newPage({ viewport: { width: 1280, height: 800 } });
-  await page.goto('http://localhost:52415', { waitUntil: 'networkidle' });
-  await page.waitForTimeout(2000);
-

-### Uploading Images to GitHub PRs
-GitHub's API doesn't support direct image upload for PR comments. Workaround:
-
-1. **Commit images to the branch** (temporarily):
-   ```bash
-   cp /tmp/screenshot.png .
-   git add screenshot.png
-   git commit -m "temp: add screenshots for PR"
-   git push origin <branch>
-   COMMIT_SHA=$(git rev-parse HEAD)
-   ```
-
-2. **Post PR comment** referencing the raw image URL (uses permanent commit SHA so images survive deletion):
-   ```bash

@@ -72,30 +72,16 @@ There are two ways to run exo:
 
 ### Run from Source (macOS)
 
-If you have [Nix](https://nixos.org/) installed, you can skip most of the steps below and run exo directly:
-
-```bash
-nix run .#exo
-```
-
-**Note:** To accept the Cachix binary cache (and avoid the Xcode Metal ToolChain), add to `/etc/nix/nix.conf`:
-```
-trusted-users = root    (or your username)
-experimental-features = nix-command flakes
-```
-Then restart the Nix daemon: `sudo launchctl kickstart -k system/org.nixos.nix-daemon`
-
 **Prerequisites:**
-- [Xcode](https://developer.apple.com/xcode/) (provides the Metal ToolChain required for MLX compilation)
 - [brew](https://github.com/Homebrew/brew) (for simple package management on macOS)
-
+  
   ```bash
   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   ```

+2. Currently a lot of requests from the API are timing out, but we still process those requests internally. If an API request times out, we should cancel all corresponding tasks to that API request (why process a request with nobody listening).
 3. Task cancellation. When API http request gets cancelled, it should cancel corresponding task.
 4. I'd like to see profiled network latency / bandwidth.
 5. I'd like to see how much bandwidth each link is using.
+6. We should handle the case where one machine doesn't have the model downloaded and then other machines are waiting on it. In this case we get loads of timeout errors because the others are waiting for the one that needs to download the model.
 7. Solve the problem of in continuous batching when a new prompt comes in, it will block decode of the current batch until the prefill is complete.
 8. We want people to be able to copy models over to a new device without ever connecting EXO to the internet. Right now EXO require internet connection once to cache some files to check if a download is complete. Instead, we should simply check if there is a non-empty model folder locally with no .partial files. This indicates it's a fully downloaded model that can be loaded.
+10. More granular control over how to deploy instances.
+12. Nix is great but installing it is a pain and we have ended up in a lot of cases having PATH issues or installation issues. For example, after rebooting mike it seemed to no longer have a nix installation and needed reinstalling. It has a bunch of broken symlinks left over from nix that caused ssh to fail, making it even harder to debug. We need consistent environments (perhaps MDM) so we can guarantee nix is installed properly on each machine.
 13. Memory pressure instead of memory used.
 14. Show the type of each connection (TB5, Ethernet, etc.) in the UI. Refer to old exo: https://github.com/exo-explore/exo/blob/56f783b38dc6b08ce606b07a5386dc40dae00330/exo/helpers.py#L251
 15. Prioritise certain connection types (or by latency). TB5 > Ethernet > WiFi. Refer to old exo: https://github.com/exo-explore/exo/blob/56f783b38dc6b08ce606b07a5386dc40dae00330/exo/helpers.py#L251
 16. Dynamically switch to higher priority connection when it becomes available. Probably bring back InstanceReplacedAtomically.
 17. Faster model loads by streaming model from other devices in cluster.
 18. Add support for specifying the type of network connection to use in a test. Depends on 15/16.
+20. Add chat completion cancellations (e.g OpenWebUI has something for cancelling an ongoing request).
+23. Do we need cache_limit? We went back and forth on that a lot because we thought it might be causing issues. One problem is it sets it relative to model size. So if you have multiple models loaded in it will take the most recent model size for the cache_limit. This is problematic if you launch DeepSeek -> Llama for example.
+24. further openai/lmstudio api compatibility
 25. Rethink retry logic
+26. Task cancellation. When API http request gets cancelled, it should cancel corresponding task.
 27. Log cleanup - per-module log filters and default to DEBUG log levels
 28. Validate RDMA connections with ibv_devinfo in the info gatherer

+Potential refactors:
