Model lineup
gpt-5.5
Frontier
OpenAI's most capable model. Best for complex reasoning, agentic flows, full-stack code generation, and long-context work.
gpt-5.3-codex
Codex-tuned
Specialized for code. Lower latency, tighter token economy, and stronger on multi-file refactors and CLI tool use.
Why Alphayellowish
Set monthly budgets per employee. We enforce them at the gateway with 429 responses — no surprise overruns.
Every engineer sees their own usage: tokens spent, requests today, hourly activity, cached savings — refreshed every 30 seconds.
One key per person. Revoke instantly when a teammate leaves. Audit who used what across your whole organization.
Cached prompt prefixes are billed at $0. Repeated Codex sessions get dramatically cheaper after the first call.
Works with Codex CLI, Cursor, Claude Code, or any OpenAI-compatible client. Swap one URL — no code changes.
Edge in BLR1. Sub-100ms latency from anywhere in India. ISO-grade infrastructure with daily backups and 5-minute health probes.
