Echo

One model. One endpoint.

The right amount of intelligence for every task. Automatically.

Echo is Tracer's frontier-level language model, adapting from a quick answer to full reasoning without modes.

The full intelligence spectrum

Every depth.
One Echo.

From an immediate answer to expansive reasoning, Echo chooses how far to go for every task. You only ask once.

Echo One model. Every depth.

Coming next: the personal layer

Your Echo.

One endpoint that becomes yours.

Your Echo will learn from how your organization actually uses it, automatically optimize where intelligence is spent, and reduce its own cost without asking your team to tune modes.

Learns from use. Protects depth. Lowers cost.
