Comments
We built Sublyx after repeatedly dealing with separate accounts, API keys, balances and incompatible endpoints across AI providers. Our goal is simple: give developers one reliable API for connecting Codex, Claude Code and their applications to leading AI models. Sublyx combines unified model access, pay-as-you-go billing, usage tracking and automatic failover, so teams can spend less time maintaining integrations and more time building. We are launching early and would love feedback on model coverage, documentation and the overall developer experience.
