Pricing difference

Together AI: Pay-as-you-go per token on hosted models with optional dedicated endpoint commitments. 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. Together AI exposes OpenAI-compatible endpoints. Change base URL, swap model IDs, and replace the API key. Existing OpenAI SDKs usually need minimal edits.

Important caveat

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

Why teams compare

Why developers compare Together AI with unlimitedcodex

  • Heavy Codex and GPT-5.6 Sol agent usage makes Together AI per-token bills unpredictable
  • You want eligible first-order GPT-5.5 XHigh at $59 then $69/month, with unlimited token consumption and 4 concurrent connections, instead of watching every request cost money
  • You need packaged customer billing and scoped keys, not just hosted inference
  • GPT-5.5 XHigh at $19/week with unlimited token consumption and 4 concurrent connections can be simpler than topping up usage credits for coding sprints

  • Unlimited token consumption with 4 concurrent connections on all four advertised packages
  • OpenAI-compatible /v1: change base URL, keep your SDK and request shapes
  • Delivered model IDs and endpoint details for Codex, embeddings, and images where supported
  • Manual provisioning - not instant automated key delivery
  • 4 concurrent connection cap limits highly parallel workloads
  • Focused on OpenAI-compatible workflows - no broad provider routing like OpenRouter or LiteLLM
