-#                hit that the API usage field reports as 0. The only ground
-#                truth for the Anthropic path is the llama-server log.
-#
-# Log location (verified): studio/backend/core/inference/llama_cpp.py:4363-4365
-#   _swa_cache_path().parent/"logs"/"llama-server"/llama-<ts>[label]-port-<P>[-try<N>].log
-#   _swa_cache_path() => $UNSLOTH_STUDIO_HOME|$STUDIO_HOME or ~/.unsloth/studio
-#   (llama_cpp.py:337-340). So default: ~/.unsloth/studio/logs/llama-server/.
-#
-#   <P> is the INTERNAL llama-server port (self._find_free_port(),
-#   llama_cpp.py:3489 / :4641) -- a RANDOM port, NOT the Unsloth port. So we must
-#   NOT filter the log glob by STUDIO_PORT (the brief's `port-<STUDIO_PORT>`
-#   glob would never match). We pick the newest llama-*.log instead.

-#   assert-prompt-cache.sh api  BASE_URL API_KEY
-#   assert-prompt-cache.sh log  EXPECT          # EXPECT = HIT | MISS

-# Local Agent Guides CI
-# =====================
-# Detects when our local-agent setup recipes drift out of sync with
-# `unsloth run`. Boots a real `unsloth run --disable-tools` server and
-# drives the coding agents end to end through the *exact* recipes defined
-# in unsloth_cli/commands/start.py (the in-repo source of truth -- there
-# is no docs/ tree). Wherever start.py has a recipe we drive the agent
-# via `unsloth start <agent> --no-launch` and execute what it prints, so
-# the test self-updates against start.py and catches silent recipe drift.
-#
-# Source-of-truth files this workflow guards:
-#   unsloth_cli/commands/start.py   the `unsloth start <agent>` recipes
-#   unsloth_cli/commands/studio.py    the `unsloth run` banner (API Key line)
-#
-# Failure taxonomy (each surfaced with a distinct ::error:: + the agent name
-# + the start.py location, so a red X is immediately triageable):
-#   (a) Unsloth server/API regression -- the dialect HTTP preflight fails
-#       BEFORE the agent runs (or the server never becomes healthy).
-#   (b) Agent package install failed   -- npm/curl install of the CLI failed.
-#   (c) Guide drift                    -- preflight passed + install ok, but
-#       the documented `unsloth start` flow produced no/garbled output.
-#
-# Agents covered (6): claude, codex, hermes, openclaw, opencode, pi.
-#   - All six have a `unsloth start <agent>` recipe, so each cell obtains its
-#     env + command from `unsloth start <agent> --no-launch` and runs THAT

-# Changelog
-
-Release notes for Unsloth and Unsloth Studio.
-
-Unsloth Studio reads this file to show release notes inside the "New Unsloth
-version" update popup. Edit it here and the popup picks the change up on the
-next update check, with no release or rebuild required.
-
-## Format
-
-Every release is a level-2 heading whose first token is the version, optionally
-followed by a date:
-
-```md
-## 2026.7.6 - 2026-07-22
-```
-
-`## [2026.7.6] - 2026-07-22` and `## v2026.7.6` also work. Everything under a
-heading, up to the next level-2 heading, is that release's notes and renders as
-Markdown in the popup.
-
-Notes are matched to one exact version. When Studio offers an update to
-`2026.7.6` it renders the `2026.7.6` section and nothing else. If that section
-is missing, the popup links out to the online changelog rather than showing
-notes from an unrelated release, so a new version needs its own section here
-before its notes can appear.
-
-Keep the newest release at the top. Lead each bullet with the change itself:
-the collapsed popup highlights the first sentence and dims the rest.
-`## Unreleased` is ignored by the popup, so it is safe to stage notes there and
-rename the heading at release time.
-
-<!-- Add new releases directly below this line. -->
-
-## Unreleased
-
-## 2026.7.5
-
-### What's Changed
-
-- AMD support is here. Train, run RL, chat with and deploy 500+ models on
-  Radeon, Instinct, Ryzen and data center GPUs across Windows, WSL and Linux,
-  up to 2x faster with 70% less VRAM and no accuracy loss.
-- Intel XPU support lands in Studio, so Arc and Data Center GPUs run chat and
-  training alongside the NVIDIA, AMD and Apple paths.
-- Local speech to text dictation runs fully offline, with slim Whisper bundles
-  and a picker for custom models.
-- DoRA training is available in Studio, selectable next to LoRA and full
-  fine-tuning in the training tab.
-- The update popup previews release notes inline, pulled from this file and
-  matched to the exact version being offered.
-
-### AMD, 23 July update
-
-Our AMD collaboration, custom Triton kernels and math algorithms bring local
-training and inference to AMD hardware. The 23 July update builds on the
-[AMD release](https://github.com/unslothai/unsloth/releases/tag/v0.1.501-beta):
-
-- RDNA2 and Gorgon Halo are supported, and the installer no longer fails to
-  detect GPUs on Strix Halo and other AMD cards.
-- RDNA4 handling is better, and HIP and ROCm failures are caught and fixed
-  automatically instead of stopping the install.
-- Unified memory safetensors loading is 2x faster, with much faster gradient
-  checkpointing on unified memory devices.
-- Voice dictation through whisper.cpp has preliminary support.
-- Rollback environments left by installs no longer eat 5GB of disk. They are
-  cleaned up automatically.
-
-Optimized ROCm builds cover GGUF and safetensors inference, and ROCm
-compatibility is improved for MI300X and MI325X. Full guide:
-[unsloth.ai/docs/basics/amd](https://unsloth.ai/docs/basics/amd).
-
-### Running larger models
-
-- Automatic GPU placement, or pick exactly which GPUs and layers to use.
-- Move MoE expert layers into system memory so larger models fit.
-- Split a model across several GPUs, or use tensor parallelism.
-- Hardware settings are saved per model and quant.
-
-### Also in this release
-
-- Remote access with `unsloth studio --secure` over free HTTPS via Cloudflare.
-- Web search reads PDF papers and manuals, and parallel tool calls, reasoning
-  output and tool retries are more reliable.
-- The model download location is configurable, so weights can live on a second
-  drive instead of the default cache.
-- Stalled Hugging Face XET downloads retry over standard HTTP, and existing
-  GGUF files are reused instead of downloaded again.

-#### Remote access: `--secure` (HTTPS tunnel) vs raw port
-By default `unsloth studio` binds to `127.0.0.1` (this machine only). To reach it from another device, pick one of:
-
-- `--secure` (recommended): serve **only** through a free Cloudflare HTTPS link. Unsloth stays bound to localhost and the tunnel provides the public URL; it fails closed (does not start) if the tunnel can't come up, so the raw port is never exposed.
+#### Nightly: MacOS, Linux, WSL:
 ```bash
-unsloth studio --secure -p 8888
+git clone https://github.com/unslothai/unsloth
+cd unsloth
+git checkout nightly
+./install.sh --local
+unsloth studio -p 8888
 ```
-- `-H 0.0.0.0`: bind the raw port on all network interfaces, reachable from anywhere on the network (subject to your firewall). It does not create a public internet URL; add `--cloudflare` to also publish an internet-reachable `https://*.trycloudflare.com` link even behind a firewall. Only use this on a network you trust.
+Then to launch every time:
 ```bash
-unsloth studio -H 0.0.0.0 -p 8888
-```
-The Cloudflare tunnel is **off by default**: `-H 0.0.0.0` exposes the raw port only, not a public internet URL. Pair the wildcard bind with `--cloudflare` (`unsloth studio -H 0.0.0.0 --cloudflare`) to also publish a public `https://*.trycloudflare.com` link, or prefer `--secure` (above), which keeps the raw port private. `--cloudflare` has no effect on a loopback bind.
-
-On a wildcard bind Unsloth works out the address to share by asking `ifconfig.me` for the public IP, then asks `check-host.net` whether that port is reachable so it can tell you if a firewall is in the way. Both contact a third party. Set `UNSLOTH_STUDIO_DISABLE_PUBLIC_CHECK=1` to skip them; the banner then shows the LAN address and no reachability line.
-
-The first time Unsloth is published on a public URL (`--secure` or `--cloudflare`) with the auto-generated admin password still in place, it asks for a new admin password in the terminal (masked input with confirmation) before the public link goes up. Without an attached terminal it warns instead and keeps the bootstrap deadline: Unsloth shuts down after `UNSLOTH_STUDIO_BOOTSTRAP_TIMEOUT` (default 1 hour) unless the password is changed in the web UI.
-
-For headless setups that cannot answer that prompt, set the initial admin password non-interactively with `--password` (only takes effect when no password is set yet; if one already exists it is a hard error, so rotate later with `unsloth studio reset-password`):
-
-```bash
-unsloth studio --secure --password 'your-strong-password'        # visible in `ps`/history
-UNSLOTH_STUDIO_PASSWORD='your-strong-password' unsloth studio --secure   # via env var
-printf '%s\n' 'your-strong-password' | unsloth studio --secure --password -   # via stdin
+unsloth studio -p 8888
 ```
 
-A literal `--password VALUE` is visible in the process list and shell history, so prefer the `UNSLOTH_STUDIO_PASSWORD` env var or `--password -` (stdin) for automation. This applies to any launch (public or a headless `-H 0.0.0.0` bind), and the password is set in the parent before the server binds, so it never reaches a re-executed child process.
-
-Server-side tools (web search, Python and terminal code execution) run as your user and are on by default. Anyone who can reach the server with the API key can run code on this machine, so keep your API key private and pass `--disable-tools` when exposing Unsloth.
+#### Nightly: Windows:
+Run in Windows Powershell:
+```powershell
+git clone https://github.com/unslothai/unsloth.git
+cd unsloth
+git checkout nightly
+Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
+.\install.ps1 --local

+Then to launch every time:
+```bash
+unsloth studio -p 8888

 #### Uninstall
 The recommended way to fully remove Unsloth Studio is the matching uninstall script for your OS. It stops any running servers, removes the install dir, the launcher data dir, the desktop shortcut, and any platform-specific entries (macOS `.app` bundle + Launch Services on Mac; Start Menu, `HKCU\Software\Unsloth` registry key and user `PATH` entries on Windows):

-
-Nothing measured this before: the backend logs "lifespan startup completed in X ms"
-but no test or CI job asserted a budget, and studio_test_kit discards the elapsed
-time of its /healthz poll. A first local run (Linux, warm cache, fast server CPU)
-found `import main` alone costs 6.6s before the server can bind, dominated by eager
-module-level imports pulled in by the `routes` package:
-
-    torch          1930 ms self
-    unsloth_zoo     914 ms self
-    routes          779 ms self
-    transformers    524 ms self
-
-Phases measured:
-  import   `python -X importtime -c "import main"`, top cumulative + per-package self
-  spawn    process start -> first byte on stdout
-  healthz  process start -> /api/health (or /healthz) answers 200
-  lifespan the backend's own "lifespan startup completed in X ms" log line

-# Unsloth Studio MCP server
-
-Unsloth can expose a local MCP server so an MCP client can inspect models and
-GPU state, validate recipes, start or stop training, inspect recipe output, and
-export a loaded model.
-
-The server is disabled by default. Enable it for a local Unsloth process with:
-
-```bash
-UNSLOTH_STUDIO_ENABLE_MCP=1 \
-UNSLOTH_STUDIO_MCP_TOKEN='use-a-local-secret' \
-unsloth studio
-```
-
-The endpoint is `http://127.0.0.1:8888/mcp/` when Unsloth uses its default port
-(a request to `/mcp` redirects to the canonical `/mcp/`). Use the actual Unsloth
-port when it is configured differently.
-
-The high-impact tools are:
-
-- `studio_status` and `list_local_models` for discovery
-- `get_training_status`, `start_training`, `stop_training`, and `list_training_runs`
-- `validate_recipe`, `get_recipe_job_status`, and `get_recipe_job_dataset`
-- `load_checkpoint` and `export_gguf`
-
-`start_training` accepts the same fields as the Unsloth `TrainingStartRequest`.
-The request is validated by the existing Pydantic model before a subprocess is
-started. Export paths use the existing Unsloth validation as well.
-
-The endpoint always requires `UNSLOTH_STUDIO_MCP_TOKEN` and checks an exact
-Bearer token for both HTTP and WebSocket connections. Keep it on localhost
-unless the deployment has an authenticated reverse proxy. The MCP endpoint is
-intentionally opt-in because tools can consume GPU memory, write model
-artifacts, and stop active work.
