## 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

## Devin

Devin sits at the agentic end of the AI coding spectrum. Instead of suggesting the next line, it takes a ticket-level goal - "add SAML SSO for enterprise customers" or "investigate this API latency spike" - explores the codebase across repositories, implements changes, runs tests, and explains the resulting pull request in plain language. It maintains a wiki-style map of the codebase so it can navigate unfamiliar services and keep documentation current as the code changes.

A defining feature is that Devin works on its own machine. It provisions Windows, Mac, and Linux virtual machines as needed, builds the project, exercises it in a browser, and can record itself clicking through the feature it just built. Long-running work continues in the cloud when your laptop is closed, and large tasks can be split across parallel agents that Devin coordinates and reports on.

For teams, Devin extends beyond one-off prompts. You can tag @Devin in Slack or Teams so it reads a thread and replies with a PR, set up automations that fix failing tests or patch vulnerable dependencies as they appear, and run security reviews. Pricing is seat-based and enterprise-oriented, with an Ultra tier for heavier autonomous usage, and Cognition has marketed large security-credit programs for enterprises.

**Pricing & Plans:** Paid, enterprise-oriented. Devin is sold on a per-seat subscription with tiered plans (including higher-capacity tiers for heavier autonomous use) plus usage allowances; Cognition also runs credit programs and enterprise agreements. Because plans and credit packages change, check Cognition's official pricing page for current numbers.

- **End-to-end autonomous coding:** Devin plans, writes code, runs tests, and opens pull requests across complex, multi-repository codebases without waiting for line-by-line approval.
- **Its own virtual machines:** Devin provisions Windows, Mac, and Linux VMs, builds and runs the project, and tests in a real browser - even recording itself using the feature it built.
- **Slack, Teams, and alert integration:** Mention @Devin in a thread to delegate a fix, or connect CI, PagerDuty, and issue trackers so it reacts to failures and alerts automatically.
- **Parallel cloud agents:** Delegate a large task and Devin splits it across parallel cloud agents that keep working after you close your laptop, then reports back.
- **Codebase wiki and automations:** Devin maintains a living map of the architecture and supports recurring automations such as dependency upgrades, test fixes, and security scans.

**Strengths:** Handles ticket-level autonomous work rather than only suggesting code completions; Tests in its own browser and VMs, which catches issues that pure code generation misses; Deep workflow integration with Slack, Teams, CI, and alerting tools; Keeps working in parallel cloud agents even when your machine is off

**Limitations:** Premium, seat-based pricing puts it out of reach for casual individual use; Complex or poorly specified tasks still need human review before merging; Maximum value depends on having a well-structured repo and clean test setup
