❓FAQs

Getting Started

1. What is Cosine and how does it work?

Cosine is an AI software engineering agent designed to integrate seamlessly into your team’s workflow.

It autonomously retrieves data, plans solutions, writes and tests code, and collaborates in real time or asynchronously – freeing your team to focus on innovation instead of repetitive tasks.

2. What are tasks and Projects

A task is an execution of the Cosine agent. You can retry a task or continue the conversation within it as many times as needed.

Projects are the code repositories where tasks are executed. They provide context for the agent and organise related work.

3. What are seats?

Seats refer to individual user licenses within a team plan. One seat equals one user. Teams can add multiple seats to enable collaboration across members within the same workspace.

4. What does the free plan include?

Our free plan includes up to 80 tasks that users can complete using the full range of Cosine’s capabilities – no credit card required.

The plan supports up to 100 projects and has no limits on users, meaning teams can build together, sharing the task limit.

Users will have access to the core Genie 2 model for autonomous coding, getting users building and shipping from day one.

5. Once I've used my free 80 tasks, what happens?

When you reach the 80-task limit on the free plan, your access to Cosine will become read-only. You’ll still be able to view your existing projects, but you won’t be able to create or run new tasks.

To continue building with Cosine, you’ll need to upgrade to either our Hobby, Professional, or Enterprise plans by entering your billing details.

6. How much does it cost to use Cosine?

Cosine uses a flat-rate, pay-per-task subscription model: your monthly plan determines how many tasks you can run, keeping costs predictable and transparent.

7. How does billing and subscription work?

Each plan includes a monthly task allowance.

Enterprise pricing scales with usage, seats, or deployment type.

8. How do I start using Cosine?

Cosine uses a simple monthly subscription that renews automatically. Each plan includes a fixed task allowance — your monthly plan determines how many tasks you can run.

Enterprise pricing scales with usage, seats, or deployment type. You can cancel anytime by giving 7 days’ notice before renewal; payments already made are non-refundable.

Technology & Capability

9. Is Cosine an autonomous engineer or copilot?

Cosine is an autonomous engineer, not a typing assistant.

It independently plans, writes, tests, and submits code without needing real-time input.

10. What tasks can Cosine complete?

Cosine handles complete engineering workflows — bug fixes, migrations, refactors, test generation, and documentation.

Each output is validated and submitted as a PR for human review.

11. Which languages and frameworks are supported?

Cosine supports all major languages — Python, Java, TypeScript, Go, C#, React, Django, Spring, and more.

Enterprises can add support for legacy or custom stacks.

12. How was the Cosine model trained?

Cosine’s proprietary model, Genie, was trained on large-scale, open-source codebases and refined through reinforcement learning on real engineering workflows — not on customer data.

It’s continuously improved to enhance code planning, reasoning, and test validation accuracy while maintaining complete isolation from private repositories.

13. What is Cosine's enterprise offering?

Cosine’s enterprise platform is built for organisations with high-security, large-scale, and complex codebases.

It supports private deployments in the cloud, VPC, or fully on-premise environments — combining autonomy, security, and scalability.

14. How is Cosine well-placed to serve enterprises?

Cosine is vertically integrated — we develop the underlying Genie model, the agent orchestration framework, and the workspace platform.

This full-stack control allows Cosine to deploy fully air-gapped, on-premise environments with maximum security, compliance, and reliability.

15. Can Cosine deliver an on-premise, fully air-gapped service to enterprises?

Yes. Cosine can be deployed fully on-premise and air-gapped, operating entirely within your private network with no external dependencies.

This configuration is used by defence, finance, and government customers who require strict data isolation.

16. Can Cosine deliver a VPC service to enterprises?

Yes. Cosine supports VPC deployments where all model inference, data processing, and storage occur inside your cloud environment (AWS, Azure, or GCP).

It’s a popular choice for enterprises needing private hosting, compliance alignment, and zero-egress data policies.

17. Who uses Cosine?

Cosine is trusted by engineering teams across finance, defence, SaaS, and manufacturing.

It’s deployed from small startups to global enterprises running air-gapped systems.

18. How does Cosine support enterprise security and compliance?

Cosine meets enterprise-grade security and compliance standards including SOC 2, ISO 27001, GDPR, and CCPA.

It offers audit logging, data residency controls, SLAs, and documentation for procurement and legal review — making it suitable for regulated and high-security environments

Security, data & privacy

19. Where does Cosine run?

Cosine runs in the cloud, inside your VPC, or fully on-premise — depending on your security needs.

Your code never leaves your chosen environment.

20. How does Cosine handle security and privacy?

Cosine follows enterprise security practices including encryption, access control, audit logging, and compliance alignment.

Customer data is never used for model training or shared externally.

21. Does Cosine train on my data?

We do not train on your repository and conversations in platform. We also maintain enterprise relationships with our AI vendors which means our inferencing and data sent our vendors is not used for training their models either.

22. Does Cosine get to read my code?

Engineers at cosine do not read or have access to your code. Cosine the agent maintains a filesystem in which it will clone and manipulate your codebase. So Cosine will see your code. But no human engineers will interact with or have access to production data

23. What do I need to share with Cosine for it to work - and what shouldn't I share?

To use our tools, you'll need to give us access to your code repository or other content you want us to work with. It's really important that you make sure this content doesn't include any personal data (like customer names, emails, ID numbers, etc.). Handling that kind of data violates our terms of use, so ensuring it's not included is your responsibility. Also, please make sure you have the rights to use and share the code/content you provide. We won't train AI on the code you give us.

24. Who sees my personal details (like my name, email, and how I use the service)

We work with trusted partners to run our service effectively and provide all the features. This means your personal info (like your name, email, IP address, and usage patterns) might be shared with companies that help us with things like cloud hosting (e.g., AWS, Google Cloud), payment processing (Stripe), service analytics, and crucially, the AI models that power our tools (like OpenAI and Anthropic). Some of these partners operate outside the UK/Europe (e.g., in the US), but we take steps to protect your data during these transfers.

25. What about the code Cosine generates? Is it ready to just drop into my project?

The code we generate is provided "as is," which means you're fully responsible for what happens next. You should always treat it like any new code: review it carefully, test it thoroughly, and make sure it actually meets your needs and quality standards before you integrate it into your own products or services. We can't be responsible for how the generated code performs once you use it.
