Direct answer
unlimitedcodex plans are GPT-5.5 Ultra Weekly at $19/week, GPT-5.5 Ultra Monthly at $59/month, and GPT-5.6 Sol Monthly at $199/month. Every advertised package includes unlimited token consumption with 4 concurrent connections and manual setup delivery after checkout. Usage is not unlimited concurrency, and packages are independent OpenAI-compatible access—not official OpenAI billing tiers.

How to choose Weekly vs Monthly vs Sol
Choose Weekly when the work is a short coding sprint, client demo week, or time-boxed experiment. Choose Ultra Monthly when the same OpenAI-compatible workflow repeats across the month. Choose Sol Monthly when the team wants the GPT-5.6 Sol package specifically.
If you need official OpenAI enterprise terms, instant self-serve keys, or more than 4 concurrent connections, this plan set is not the right product shape.
What “usage” means in Search Console queries
Queries such as unlimited codex usage usually mean package limits, not a separate usage product. The public boundary to plan around is concurrent connections and the selected package window.
After delivery, verify fit with /v1/models and one tiny chat/completions request before a long agent loop so usage expectations match the delivered endpoints.
Verification checklist
Match package length to sprint length before checkout.
Budget for 4 concurrent connections in agent or multi-tab workflows.
Allow delivery time before the sprint starts.
Confirm model IDs after delivery.
Use Weekly only when a short window is enough.
