Optimised for complex codebases
“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.”

Cosine: Built to Serve Enterprise Needs
We understand enterprise reality: large backlogs, strict security, high
accuracy requirements, and sprawling services and teams. Cosine is built
for it, so engineers ship faster.
Large backlogs? Cosine scopes, executes, and returns PRs ready to
review. High security? Deploy fully air-gapped or inside your VPC. Need
accuracy? Our enterprise-trained LLM beats generic assistants on real
code. Complex orgs? Cosine works across repos, runs tasks in parallel,
respects ownership, and plugs into Jira, GitHub, Slack and more.
