About
Cosine is an enterprise-grade agentic AI software engineer that autonomously handles real software development tasks at scale. Built specifically for complex, high-security codebases, Cosine integrates seamlessly with tools like GitHub, Jira, Slack, Linear, Trello, and Asana so developers can assign and launch tasks directly from their existing workflows. Powered by Cosine's proprietary Genie 2 model, the agent achieved a 72% pass rate on the SWE-Lancer benchmark — a production-grade agentic coding evaluation with 237 real-world tasks worth $236K — outperforming models from OpenAI and Anthropic. Cosine excels at multithreaded feature development, comprehensive bug scanning and fixing, large-scale refactors, library migrations, CI/CD pipeline maintenance, security-focused code fixes, and auto-generating always up-to-date documentation. Teams can deploy Cosine fully air-gapped or within their own VPC, making it suitable for regulated industries and enterprises with strict data governance requirements. Cosine drafts pull requests automatically, keeping humans in control of review and merge decisions. Customers have reported clearing 10 days of backlog in minutes, accelerating junior developer iteration by multiple times, and migrating multi-million line codebases to new infrastructure — all with measurable productivity metrics included.
Key Features
- Parallel Multithreaded Task Execution: Launch multiple coding tasks simultaneously — bug fixes, new features, and refactors — and let Cosine handle them all in parallel without blocking your team.
- Enterprise-Grade Deployment Options: Deploy Cosine fully air-gapped or within your own VPC to meet strict data security, compliance, and governance requirements.
- Deep Tool Integrations: Connect to GitHub, Jira, Slack, Linear, Trello, Asana, and more so developers can assign and track tasks directly from their existing workflows.
- Automated PR Generation: Cosine drafts pull requests for every task it completes, keeping engineers in the review seat while eliminating the time spent writing boilerplate code and PRs.
- Genie 2 Model — SWE-Lancer Leader: Powered by Cosine's proprietary Genie 2, achieving 72% on the SWE-Lancer benchmark — surpassing OpenAI and Anthropic on production-grade software tasks.
Use Cases
- Accelerating enterprise software delivery by running multiple feature builds and bug fixes in parallel across large codebases.
- Clearing engineering backlogs quickly by autonomously resolving tickets assigned directly from Jira, Linear, or GitHub Issues.
- Migrating and modernizing legacy codebases or moving services to new infrastructure with minimal manual engineering effort.
- Maintaining CI/CD pipelines and enforcing security compliance through automated code scanning and remediation.
- Generating and keeping up-to-date technical documentation for complex, fast-moving enterprise codebases.
Pros
- Top Benchmark Performance: Genie 2 leads the SWE-Lancer benchmark with a 72% pass rate, giving enterprises confidence in its ability to handle real-world production tasks.
- Air-Gapped & On-Premise Support: Rare among AI coding tools, Cosine supports fully air-gapped deployment, making it accessible to regulated industries with strict security requirements.
- Fits Existing Developer Workflows: Native integrations with GitHub, Jira, Slack, and other popular tools mean teams don't need to change how they work to adopt Cosine.
- Proven Enterprise Impact: Customers report dramatic gains like clearing 10 days of backlog in minutes and migrating 2 million-line codebases in just weeks.
Cons
- Enterprise-Focused Pricing: Cosine is designed for enterprise teams and requires contacting sales — there is no self-serve free or freemium tier for individual developers.
- Requires Setup and Integration: Connecting Cosine to your codebase, deployment environment, and project management tools requires initial configuration effort.
- Human Review Still Needed: While Cosine automates code generation and PR drafting, engineering teams must still review and approve all changes before merging.
