Pricing FAQ
chevron_right Why is Mythos Preview so much more expensive than Opus?
Mythos represents a fundamentally new model tier — not an Opus upgrade. The 5x cost reflects the massive compute required for frontier-class reasoning and cybersecurity capabilities.
chevron_right Can I use Mythos Preview today?
Only if your organization has been approved through the Glasswing program or early access pipeline. Mythos is not available for general API access.
chevron_right Will Mythos pricing decrease over time?
Anthropic has indicated that efficiency improvements are needed before broader release. Historical precedent suggests costs will come down as infrastructure scales, but no timeline has been given.
