Pricing difference

OpenAI API: Pure pay-as-you-go per token, request, or modality with batch and priority tiers. unlimitedcodex: GPT-5.5 XHigh Weekly is $19; eligible first-order welcome pricing is XHigh Monthly $59 then $69/month, GPT-5.6 Sol Weekly $69 then $89/week, or Sol Monthly $179 then $199/month. One welcome price is available per account, with unlimited token consumption, 4 concurrent connections, and Stripe billing.

Migration effort

Difficulty is easy. Point base URL to api.openai.com/v1 with an OpenAI key and official model IDs. Reverse migration to unlimitedcodex is equally simple with a base URL swap.

Important caveat

unlimitedcodex setup is manual after checkout, with expected delivery in 10 minutes to 5 hours, and the service is independent from OpenAI.

Use OpenAI for official first-party access and instant self-serve keys. Use unlimitedcodex for independent OpenAI-compatible access with predictable spend.

Billing

OpenAI API

Per-token metering can add up quickly on input- and output-heavy coding workloads.
