About
Buildt AI, powered by Cosine and its proprietary Genie 2 model, is a self-sufficient agentic AI software engineer purpose-built for enterprise development teams working in complex, high-security codebases. Unlike standard coding assistants, Buildt operates autonomously across multiple tasks simultaneously — handling bug fixes, feature development, large-scale refactors, and library migrations in parallel. Buildt connects directly into your existing workflow tools including GitHub, Jira, Linear, Trello, Asana, and Slack, enabling task assignment and execution from the platforms your team already uses. It drafts pull requests with full context so engineers can review, approve, and merge with confidence. Security-conscious enterprises can deploy Buildt fully air-gapped or within a private VPC, making it suitable for organizations with strict data governance requirements. Its 'research mode' allows rapid understanding of legacy or third-party repositories. Additional capabilities include auto-generated and always-up-to-date documentation, CI/CD optimization, compliance-aligned security fixes, and framework modernization. Powered by Genie 2, Cosine achieves 72% on the SWE-Lancer benchmark — outperforming models from OpenAI and Anthropic — making it the leading agent for production-grade software tasks. It is trusted by engineering teams at major enterprises looking to dramatically increase development velocity without compromising security or code quality.
Key Features
- Parallel Autonomous Task Execution: Launch multiple bug fixes, features, and refactors simultaneously; Cosine handles them in parallel and drafts PRs for your review.
- Deep Tool Integrations: Plugs directly into GitHub, Jira, Linear, Trello, Asana, and Slack so tasks can be assigned and executed without leaving your existing workflow.
- Air-Gapped & VPC Deployment: Deploy fully air-gapped or within your own VPC for maximum data security, making it suitable for high-compliance enterprise environments.
- Legacy Codebase Understanding: 'Research mode' enables rapid comprehension of large legacy or third-party repositories, accelerating onboarding and modernization projects.
- Genie 2 Model Performance: Powered by the proprietary Genie 2 model, achieving 72% on SWE-Lancer — the most realistic production-grade agentic coding benchmark.
Use Cases
- Automating parallel feature development across multiple engineering tickets to accelerate sprint velocity
- Performing large-scale library updates and framework migrations on mature enterprise codebases
- Running comprehensive bug scanning, fixing, and test writing without manual developer intervention
- Maintaining auto-generated, always-up-to-date documentation for complex internal codebases
- Executing security-focused code fixes and compliance-aligned improvements in high-governance environments
Pros
- Enterprise-Grade Security: Supports fully air-gapped and VPC deployment options, making it a viable choice for organizations with strict security and compliance requirements.
- Industry-Leading Benchmark Performance: 72% pass rate on SWE-Lancer outperforms competing models from OpenAI and Anthropic on real-world production coding tasks.
- Seamless Workflow Integration: Connects to a wide range of project management and collaboration tools, enabling task assignment and execution without process disruption.
- Parallel Multitask Execution: Handles multiple development tasks concurrently, significantly accelerating delivery and clearing backlogs faster than a single engineer could.
Cons
- Enterprise-Focused Pricing: Designed primarily for enterprise teams; pricing is not publicly listed and may be out of reach for individual developers or small startups.
- Requires Human Review Step: While it drafts PRs autonomously, a human review and approval step is still required before merging, which may limit fully automated pipelines.
- Dependent on Existing Tooling: Full value is unlocked when integrated with GitHub, Jira, or Slack; teams without these tools may experience a more limited feature set.
