## Pricing

**Model**: Freemium

Offers a free plan with an 80-task limit. Paid subscription plans include Starter ($19/month), Builder ($49/month), Team ($99/month), Scale ($199/month), and Professional ($999/month), all based on monthly Cosine Credit allocations for task execution. Enterprise pricing is custom.

## Who it is for

- **Best for**: Engineering teams performing large-scale code refactors, library migrations, and complex multi-file tasks that require autonomous, background execution.
- **Not ideal for**: Teams prioritizing greenfield development, projects with fuzzy or ill-defined requirements, or organizations lacking structured code review processes to validate agent outputs.

## Verdict

A powerful, agentic platform that excels at handling heavy-duty, repetitive engineering workflows asynchronously, though it requires disciplined human review for its parallelized outputs.

## Recent updates

The company has rebranded its model family to Lumen (including Scout and Outpost models) and shifted focus toward a sovereign AI initiative, with Genie now considered a legacy brand identifier.
