# The coding agent built for _enterprise_

Deploy anywhere: on-premise, fully air-gapped, or in your secure cloud

## What makes Cosine different?

Cosine isn’t just a coding agent. We’re also a machine learning research lab that post-trains AI models on high-quality human coding data, in collaboration with OpenAI.

The outcome? State-of-the-art coding accuracy, whether you’re on-premise or in the cloud. An agent tailored to your context and your code.

Run Cosine where you need it - on our cloud, your VPC, or fully on-premise, airgapped. Use your preferred models or custom-trained ones.

## 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.

## The impact our customers have seen

- **6x** Increase in A/B testing through Cosine
- **12x** Faster iteration on new features by junior developers
- **43 minutes** Time taken to clear 10 days’ worth of backlog
- **7 weeks** Time taken to move a mature 2 million line codebase to AWS

> “Cosine shows what it looks like when AI works like a real-world developer. Genie 2 mirrors how engineers reason through complexity. **It’s a foundational leap for software development.**”  
> *Laura Modiano, OpenAI Start-Ups EMEA lead*

> “ **I definitely see Cosine as one of the leading contenders in agentic programming.** Most others just can’t do it, and they're cracking the code. The way Cosine has fine-tuned their model is particularly impressive: it ensures that the agent actually behaves well and digests a lot of context, which other providers consistently struggle with.”  
> *Nick Hughes, Technical Director*

> “Cosine fits perfectly with agile and buddy programming it’s like having an AI partner. Both junior and senior developers picked it up instantly. **It’s boosted productivity and become part of our team.**”  
> *Cris Flagg, CEO, Flagg Consulting*

## Safety, Trust & Transparency

Cosine is built for enterprises where trust isn’t optional. 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.

### Your IP stays yours

All inputs and outputs remain your intellectual property.

### Enterprise-grade compliance

SOC 2 attested, ISO 27001 aligned.

### Full visibility

Audit logs and fine-grained access controls, built in.

### Seamless integration

Works with your identity provider (IdP) for airtight access.

### Zero data leakage

No training on shared models. Your code never leaves your environment.

### Private deployments

On-prem or VPC air-gapped isolation options ensure full control.

### Regulatory alignment

Designed for strict regimes like FINRA, HIPAA, ITAR, GDPR.

### Red-team tested

Adversarial testing to prove resilience against attacks.

### Encryption everywhere

Data is encrypted at rest and in transit with enterprise-grade keys.

### Granular governance

Role-based access and policy enforcement tailored to sensitive orgs.

### Customer-controlled retention

You decide what’s stored, for how long, or whether at all.

### No shadow AI

No “mystery” training data, no co-mingling with public models.

### Continuous compliance

Optional real-time monitoring and alerts on usage anomalies.

### Defence-grade hardening

Designed to fit into zero-trust environments.
