What the publisher says
As described on AWS Marketplace.
Cosine is your AI-powered software engineer, designed to assist you in tackling your development tasks. Think of it as a reliable teammate that can handle tickets, suggest code changes, and integrate seamlessly with your existing workflow. Cosine can be deployed on cloud, on prem, either in a VPC or fully air-gapped, keeping your data, usage and outputs fully private, compliant and safe adhering to all company policies.
What is Cosine?
Show the rest of the publisher’s description (28 more lines)
Cosine is an AI-powered software engineering model capable of:
- Solving bugs.
- Building features.
- Refactoring code.
- Handling tasks autonomously or collaboratively.
Cosine connects natively with your codebase, no matter the language or complexity, and ticketing systems like GitHub, Jira, or Linear. You can prompt it or provide it with a task or ticket, and Cosine works in the background to propose code changes that has been tested and verified, opening pull requests for your review. It's like having an extra pair of hands to help you manage your backlog. Every line of code, every output, every decision is handled with the highest standards of security and compliance - far beyond what other AI tools can offer. Our offering helps enterprises in regulated sectors deploy high-quality coding agents with no risk of data egress.
Key Features
- Autonomous Operation: Assign tasks to Cosine, and it will work independently to generate solutions.
- Seamless Integration: Connects with your existing tools and workflows without requiring significant changes.
- Human-Like Reasoning: Designed to understand and navigate complex codebases, mimicking the thought process of a human engineer.
- High Performance: Achieved a leading score on the SWE-Lancer benchmark outperforming OpenAI and Anthropic, demonstrating its effectiveness in software engineering tasks.
How Cosine Works
- Task Assignment: Provide Cosine with a task or ticket through your preferred platform or directly via its interface.
- Codebase Analysis: Cosine clones your repository and analyzes the code to understand the context.
- Solution Development: It develops a solution, whether it's fixing a bug, adding a feature, or refactoring code.
- Pull Request Creation: Cosine submits a pull request for your review.
- Iteration: Based on CI/CD feedback or your input, Cosine can iterate on the solution until it meets the desired standards.
Why Cosine
Traditional development tools often require constant human oversight and interaction. Cosine changes this by operating asynchronously, allowing you to:
- Reduce time spent on routine tasks.
- Maintain focus on complex problem-solving.
- Accelerate development cycles.
Benefits of using Cosine
- Rapidly scale team output - Allow your team to tackle more concurrent tasks without the need to increase supervisor headcount. Increase throughput and output
- Remove cold starts - Developers never start from a blank slate. Every codebase becomes a familiar codebase and time to start reduced
- Exponential A/B testing - Instead of trialling only 1 or 2 variants, the same level of resource can build 10, 20, 30+ different ideas at once
- Eliminate Backlogs - Backlog tasks, bugs and ideas no longer forgotten about, and assign the entire backlog directly from Jira, Linear or Github
By leveraging Cosine's capabilities, you can enhance productivity and streamline your development process.
Highlights
Highlighted by the publisher on AWS Marketplace.
Optimized for on-premise: We post-train any open-source model of your choice, optimising it specifically for coding. The result is maximum accuracy per GPU and full control over your infrastructure.
Best-in-class accuracy in the cloud: Our default model - post-trained on GPT-5 - already outperforms OpenAI and Anthropic in coding accuracy and reliability.
Custom post-training for your context: We can train a model on your own repos, frameworks, or specific languages (like COBOL or Fortran), creating an agent with a deep understanding of your internal systems and legacy code.

Confirmed means matched to a public authoritative registry. Claimed means the vendor or its listing states it, not yet cross-checked. A framework not shown was not found in any source we hold, which is not evidence against it. Not listed means a scoped registry check found no match for this vendor's domain: a No is a scoped registry check, not a compliance judgment. Confidence bands: 95% domain-verified, 90% registry-checked, 80% self-attested, 70% weak signal. Self-attested items marked “vendor's site” are gathered from the vendor's own website and are not verified by us.

Unknown means this listing does not publish a repository. It is not a statement that the code is closed, and a linked repository is not a claim that the publisher wrote it: the registry computes that relationship privately and does not publish it.
Evidence risk is the share of the build you cannot see before you deploy, not a security rating. Sign in to see the layer-by-layer basis for this band.
