PD: GPT Image 1 & 1.5 (comfyui_AuthToken)

Every image model in the comfyui-PD_comfy-api-node pack gets an API-key version and an AuthToken version, and GPT Image 1 & 1.5 is no exception. This is the token flavor: same engine as PD: GPT Image 1 & 1.5 (apikey) - GPT Image 1 and the December 2025 1.5 refresh, run through ComfyUI's hosted proxy - but you authenticate with a session token instead of a minted ComfyUI API key.

When to pick this over the key version

The token is the auth_token_comfy_org JWT from your logged-in ComfyUI session, grabbed with the pack's bundled Tampermonkey userscript at temperay/PD_comfyui_token_grabber.user.js. Load the app, log in, let the script lift the token out of localStorage, paste it in. The node sends it as Authorization: Bearer <token>.

It's the lower-friction path if you already have a ComfyUI account and don't want to manage a key - and the higher-fragility path, because session tokens expire and carry your full account permissions. For a quick concept image tonight, it's great. For a workflow you'll rerun next month, the key variant is the one that won't 401 on you mid-run.

Inputs and outputs

These match the API-key twin field for field:

• auth_token - the grabbed session token.
• prompt - what to generate or edit.
• model - gpt-image-1 or gpt-image-1.5 (default).
• quality - low/medium/high (default low; drives cost and time).
• background - auto/opaque/transparent - GPT Image 1 still has transparent-background support, unlike GPT Image 2.
• size - auto, 1024x1024, 1024x1536, 1536x1024.
• n - 1–8 images.
• seed - present here with a full range; still treat results as non-deterministic.
• Optional image (editing) and mask (inpainting, white = replaced).

Outputs: image and info.

Installing and gotchas

cd ComfyUI/custom_nodes
git clone https://github.com/7BEII/comfyui-PD_comfy-api-node.git

Restart, find it under PD_Tools/Image_Generation. (The README's pip install -r requirements.txt is a dead instruction - no requirements file ships; the pack's real dependency is ComfyUI's official API nodes, bundled with Desktop.)

Troubleshooting is token-shaped:

• 401/403 - the token expired. Re-run the grabber.
• Black output - error placeholder; info has the message.
• Transparent backgrounds flaky - test one call before depending on it, since the proxy path can vary.
• Don't share workflows with a token baked in - it's a live credential.

If token expiry is starting to annoy you, the sibling API-key node gives you the same GPT Image 1/1.5 engine with a credential that doesn't rot - and if you want the newer model with multi-image editing, that's GPT Image 2, also in this pack.
