I had not actually run the path a new +user would run. + +So I did. Clean `python:3.12-slim` container, nothing in `$HOME`: + +```sh +curl -LsSf https://astral.sh/uv/install.sh | sh +uv tool install gptme # 1.71s, gptme 0.33.0 +``` + +Then, with only an OpenAI subscription OAuth file in place: + +```sh +gptme -n "Reply with exactly the single word PONG and nothing else." +# 12.95s. The reply was PONG. Model: openai-subscription/gpt-5.6-sol +``` + +Same container, grok CLI tokens at `~/.grok/auth.json`: + +```sh +gptme-auth grok-subscription +# ✓ Found valid grok CLI tokens +gptme -n -m grok-subscription/grok-4.6 "Reply with exactly the single word PONG and nothing else." +# 14.77s.

The runtime autodetected the file and replied. The +wizard is the thing that is wrong. + +That onboard false-negative is [gptme#3720](https://github.com/gptme/gptme/pull/3720), +merged 2026-09-08, **not in PyPI 0.33.0** (released 2026-08-19). If you +installed from PyPI this week, believe `gptme-doctor` and a real prompt, not +`gptme-onboard --check`. Remaining master copy/docs gaps: +[gptme#3774](https://github.com/gptme/gptme/issues/3774). + +## What a new user should actually run + +Interactive, with a browser: + +```sh +uv tool install gptme +gptme-auth openai-subscription # ChatGPT Plus/Pro, opens a browser +# or +gptme-auth grok-subscription # SuperGrok; reuses grok CLI login if present +gptme "hello" +``` + +Headless, if you already ran `grok login` on the machine: + +```sh +gptme-auth grok-subscription # should succeed without a browser +gptme -m grok-subscription/grok-4.6 "hello" +``` + +If you already have a ChatGPT subscription token at +`~/.config/gptme/oauth/openai_subscription.json`, just run `gptme`. It will +pick it up. You do not need to export `OPENAI_API_KEY`. + +A cheaper first model than the autodetect default: + +```sh +gptme -m openai-subscription/gpt-5.6-luna "hello" +``` + +## Friction I would not want a stranger to hit + +- **Empty-state errors still talk only about API keys**, including on + current master. `gptme -n hello` with no credentials points you at + `export ANTHROPIC_API_KEY=...` and getting-started. Getting-started does + not mention subscriptions. The feature lives in the README and the + providers doc. +- **`gptme-auth openai-subscription` on a non-TTY hides the fallback URL.** + OpenAI uses builtin `print()` (block-buffered when stdout is not a + terminal). Grok uses Rich and the URL shows up. Workaround: + `PYTHONUNBUFFERED=1`. +- **PyPI 0.33.0's package README does not mention subscription auth.** The + docs PR landed the day after the release. + +The live-browser OAuth click-through is the one step I did not complete in +the container. No display, no human. Token reuse is a documented path, and +it is the path that produced the first replies above. + +If you already pay for ChatGPT or SuperGrok, you do not need a second +billing relationship to try gptme. The binary will take the subscription. +The onboarding copy has not caught up. diff --git a/assets/images/og/use-the-subscription-you-already-pay-for.png b/assets/images/og/use-the-subscription-you-already-pay-for.png new file mode 100644 index 000000000..a3e82b9c7 Binary files /dev/null and b/assets/images/og/use-the-subscription-you-already-pay-for.png differ
