Sovereign AI models and autonomous coding agents for regulated, secure environments
A family of frontier LLMs trained on the UK's Isambard-AI supercomputer and specialised for UK and EU regulatory frameworks, legacy programming languages and mission-critical workflows, with 1T and 200B parameter variants announced.
Run Cosine fully air-gapped inside your own infrastructure, in a dedicated managed single-tenant environment, or through Cosine's managed public cloud—with data handling and access controls set by you.
Agent surfaces that cover terminal-driven engineering tasks, everyday desktop research and document work, and long-running parallel jobs in isolated cloud environments.
Designed for defence, government and critical national infrastructure teams that need frontier reasoning inside disconnected networks.

The AI coding agent for building ambitious software
An agentic mode that plans changes, edits several files at once, runs tests, and iterates until the task is complete.
Background agents spin up their own environments to build, test, and demo features in parallel, then hand back results for review.
Fast inline suggestions plus codebase-wide semantic search and indexing so answers reflect your actual repository.
Switch between leading frontier models from multiple providers, or let Cursor select a model automatically for each task.
Provides powerful parallel AI coding agents via a desktop command center, but is less integrated into a traditional editor.


SpecialistEnables instant cloud-based full-stack app building from natural language, but is less suited for local offline repositories.
#2
Free / Open-sourceOffers unmatched extension support and official Copilot integration, but lacks Cursor's out-of-the-box deep codebase indexing and agentic editing.

Features advanced multi-file planning and codebase reading, but lacks Cursor's smooth chat-to-edit inline workflows.

The AI coding agent that turns ideas into shipped software
Focuses on spec-driven engineering and structured agent planning, but offers less fluid ad-hoc inline code generation than Cursor.
SpecialistOperates as a fully autonomous software engineer for complex tasks, but lacks the snappy interactive inline editing of Cursor.

Free / Open-sourceThe coding agent that learns your coding taste

Autonomous AI co-founder that plans, codes, and markets your company 24/7
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language
Delivers a polished AI-native IDE experience with multi-file generation, but has a smaller ecosystem than Cursor.

SpecialistAI-powered terminal and agentic software factory for development teams
