Your choice of deployment:
Fully air-gapped
In your VPC
Different enterprises have different security requirements and different
needs. That’s why Cosine is available for whatever on-premise set-up you
have. The outcome is state-of-the-art coding accuracy, whatever your
context.
Fully air-gapped, on-premise
Fully installed on your infrastructure with no external dependencies
or data egress.
Option to fine-tune on your internal codebase, frameworks, or
languages (e.g. COBOL, Fortran) for unmatched legacy system support.
Post-train any open-source model of your choice for software
engineering, optimised by Cosine’s ML research lab to drive maximum
accuracy per GPU.
In your VPC
Deploy Cosine within your VPC for complete control over your data and
infrastructure.
Secure, private deployment: Cosine runs entirely in your cloud, behind
your firewall.
Access to our frontier, state-of-the-art coding model Lumen for
maximum accuracy and reliability.
“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
