See everything your AI sees.
Others show you metadata — latency, tokens, cost. Costa shows you the session: every prompt, every tool call, every decision. Your agents see what you see. And learn from it.
Trim removes wasted tokens. Cosmic Routing spreads your calls across models. Better answers, lower cost.

Redact what's sensitive. Block what shouldn't run. Record everything. Code and AI working together — so access bends to context, not the other way around.
Failover, budgets, rate limits, structured outputs — and Trim, which quietly stretches every subscription you're already paying for. Consistent across OpenAI, Anthropic, Vertex, Azure, Bedrock and every model that matters.
Agents do the keystrokes. People do the judgment. Costa makes sure neither is flying blind.
So the work lands.
Finds your agent. Wires it to Costa Gateway. Walks you through the rest.
