Unreal Labs launches Unreal Agent, an agent harness cutting costs vs Codex

Unreal Labs introduced Unreal Agent, a harness for running AI agents that it says delivers up to 40% cost savings compared to OpenAI's Codex and up to 20% savings compared to Pi, without hurting performance on production workloads and coding/science benchmarks. The company says the harness manages tool calls asynchronously, removing the need for the underlying model to handle waits, polls, and heartbeats itself.
