I recomend you use Luna 5.6 on medium. or max settings

it get job faster , and its fast, and its more adjusted to the new updates.....

the reality is you arent going to get the same juice out of 5-3

know that 5.6luna is 4x cheaper than 5.3
know that its 4x times better than 5.4medium

honestly I understand why you would want to use 5.3,

(seprated limits, and cheaper usage) moar clank for the nickle , thus, therefore - I recomend you use Luna5.6

I can now reproduce this very clearly on a ChatGPT Pro account.

My Usage & Billing page shows:

  • General Codex weekly limit: 0% left, resets Aug 20 at 5:33 AM
  • GPT-5.3-Codex-Spark weekly limit: 100% left, resets Aug 23 at 10:21 AM

In the Codex app, with 5.3 Codex Spark High explicitly selected, every request is blocked with:

“You've hit your usage limit. Add credits to continue, or try again at Aug 20, 2026, 5:33 AM.”

I then installed the official Codex CLI under WSL, authenticated using the same ChatGPT Pro account, and launched:

codex --model gpt-5.3-codex-spark

The CLI confirmed gpt-5.3-codex-spark as the active model and successfully answered a test request (“Say hello” → “Hello!”).

So the Spark entitlement and quota are working on the account. The same model works via CLI but is blocked in the Codex app by the exhausted general weekly quota.

I have screenshots showing the separate quotas, the app failure, the CLI model selection, and the successful Spark response.
