## Cosine

Cosine started as an AI software engineer aimed at understanding and working across entire codebases, and has since grown into a sovereign-AI company serving organisations that cannot send sensitive data to third-party frontier models. The product line now centres on the Lumen model family, including Lumen Sovereign—a frontier model trained on the UK's Isambard-AI supercomputer with UK Government backing—alongside Lumen Outpost and Lumen Scout variants for different deployment postures.

Alongside the models, Cosine ships three agent surfaces. Cosine CLI delegates complex engineering tasks to agents that reason across full codebases, write and refactor software, run tests and work autonomously in an existing development environment. Cosine Desktop brings autonomous assistance into everyday desktop workflows for research, document and spreadsheet analysis and coordination across local files and tools. Cosine Cloud assigns long-running work to isolated environments, runs tasks in parallel and lets teams review results together with built-in controls for usage, model access and spend.

Security and sovereignty are the organising principles. Deployments can be fully air-gapped inside a customer's own infrastructure with no external connectivity, run in a dedicated managed single-tenant environment, or accessed through Cosine's managed public cloud. Organisations can also post-train an open-weight model, adapt Lumen Sovereign to their own domain knowledge, or commission an entirely new foundation model built to their requirements.

**Pricing & Plans:** Cosine offers a free trial entry point and a public cloud tier; enterprise, single-tenant and air-gapped deployments are quoted individually. Check the pricing page or contact the team for current figures.

- **Lumen Sovereign frontier models:** 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.
- **Three deployment models:** 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.
- **Cosine CLI, Desktop and Cloud:** Agent surfaces that cover terminal-driven engineering tasks, everyday desktop research and document work, and long-running parallel jobs in isolated cloud environments.
- **Air-gapped and defence-grade use:** Designed for defence, government and critical national infrastructure teams that need frontier reasoning inside disconnected networks.
- **Custom and post-trained models:** Adapt Lumen Sovereign to your organisation's specialist knowledge, post-train an existing open-weight model for your tasks, or work with Cosine to build a purpose-built foundation model from scratch.

**Strengths:** Deployment flexibility spanning public cloud, managed single-tenant and fully air-gapped setups; Model line purpose-built for regulated industries rather than adapted from a general-purpose assistant; Strong sovereign and data-residency story, including UK Government backing for Lumen Sovereign; Covers both day-to-day coding agents and long-running autonomous cloud tasks

**Limitations:** Enterprise and sovereign deployments are quote-based, so pricing transparency is limited; Sovereign model availability has announced timelines rather than immediate general availability; Air-gapped and custom-model projects typically require significant internal infrastructure and lead time

## Cursor

Cursor's editor looks familiar to anyone who has used a modern IDE, but the center of gravity is the agent. Instead of only suggesting the next line, it can read a task description, inspect the repository, produce an implementation plan, modify many files, run commands, and report back with a summary of what changed. Developers keep control by approving plans, reviewing diffs, and stepping in wherever judgment is needed.

The product has expanded well beyond a single application. Cloud agents can run on their own machines for extended periods, Cursor ships a CLI, and integrations bring the same agent into Slack and GitHub so work can be handed off without switching tools. A model picker lets you use frontier models from several providers, or rely on automatic selection per task.

This makes Cursor a good fit for teams that want measurable velocity gains on large codebases while keeping human review in the loop. The trade-offs are mostly about cost and process: capable agents consume quota, remote indexing raises questions for security-conscious organizations, and teams need light conventions for when to delegate versus write code directly.

**Pricing & Plans:** Cursor uses a freemium model: you can start for free with limited usage, then move to paid Pro, team, and enterprise tiers that unlock higher model limits, cloud agents, and administrative controls. Exact seats and credit allowances change over time, so check cursor.com/pricing for current numbers.

- **Agent-driven code changes:** An agentic mode that plans changes, edits several files at once, runs tests, and iterates until the task is complete.
- **Cloud and parallel agents:** Background agents spin up their own environments to build, test, and demo features in parallel, then hand back results for review.
- **Tab completion and codebase context:** Fast inline suggestions plus codebase-wide semantic search and indexing so answers reflect your actual repository.
- **Multi-model flexibility:** Switch between leading frontier models from multiple providers, or let Cursor select a model automatically for each task.
- **CLI, Slack and GitHub workflows:** Run Cursor from the terminal, chat with it in Slack, and let it review or open pull requests in GitHub without leaving your workflow.

**Strengths:** Strong repository-wide context and multi-file edits; Agent runs in the editor, cloud, CLI, Slack, and GitHub; Choose from multiple frontier models in one place; Familiar IDE experience for developers coming from other editors

**Limitations:** Requires a paid plan for the most capable models and higher usage; Learning curve to use agentic workflows effectively; Heavy cloud agent usage can consume plan quota quickly; Codebase indexing sends code to remote services, which some compliance teams must review
