Agents running,
while you sleep
while you sleep
Cosine in the cloud keeps work moving after your local environment runs out of time, context, or attention.
Four Modes.
For Every Kind of Work.
For Every Kind of Work.
From scoping work to autonomous execution, you can choose how much
oversight you want and switch modes as the task evolves.
Auto
Reads, writes, runs, and iterates without stopping. Set the task and walk away.
Plan
Research broad changes before committing to edits or execution.
Swarm
Split bigger efforts into coordinated agent workstreams without losing context.
Manual
Asks before making changes. You stay in control.
Every surface gets better when the platform exists underneath it.
Escape velocity for long-running work
Keep running, even after local runs out.
The platform keeps the same workflow alive across retries, long-running
tasks, overnight execution, and shared review.
Remote execution
Agents run on isolated platform workers or your own SSH targets. Kick off a complex refactor, board a flight, and come back to a finished diff. No babysitting required.
Parallel agents
Run 20+ agents simultaneously on isolated worktrees. They work in parallel with zero coordination overhead — no merge conflicts, no shared state. Everything resolves before you see a diff.
Your machine as a node
When the CLI or Desktop is running, your machine is part of the Cosine network. Start a task on your laptop, continue it from your phone. The work keeps running — on your hardware, with your files.
Approval-gated actions
Read operations are autonomous — indexing, fetching, monitoring. Write operations only go out when you say so. Push code, send a Slack message, file a PR comment — one confirmation, then it executes.
MicroVM isolation
Every agent session runs in a hardware-isolated MicroVM — the same technology that powers AWS Lambda. ~125ms boot time. Dedicated kernel. Secure by default, not as an afterthought.
Model-agnostic
Codex, Sonnet, Opus, Kimi K2.5, GLM 5.1, MiniMax M2.7, Qwen 3.6 Plus, Gemini. Bring your ChatGPT subscription. The platform doesn't lock you to any provider — your results shouldn't depend on a single model.

From idea to done.
While you weren't watching.
While you weren't watching.
01
Delegate the task.
Describe what needs to happen. Pick the model and the scope. Hit run. Whether it's a targeted fix, a feature across 15 files, a migration, or a batch of issues — the platform takes the brief and gets to work immediately.
02
Agents spin up.
Each subtask runs in its own MicroVM on an isolated worktree. They work in parallel, never stepping on each other. If one fails, others keep going. The platform tracks state, handles retries, and keeps you updated without interrupting you.
03
Results surface.
As agents complete, diffs appear in the platform UI — or in your Desktop app, or accessible via phone. Review what was built, redirect anything that missed the mark, approve the changes that are ready.
04
Ship with confidence.
Every write action, committing, pushing, opening a PR, sending a Slack update, is approval-gated. The platform queues them, presents them clearly, and executes in the right order the moment you confirm. Nothing ships without your sign-off.

Move between surfaces any time
Start local. Scale when you're ready.
Cosine is one product across three surfaces: CLI, Desktop, and Cloud.
Each extends the last — nothing is thrown away when you go further.
The desktop is the hub. When you want to run tasks overnight, spin up
20 agents in parallel, or keep working from your phone while your
laptop runs a long job — the cloud is already connected. Same account,
same context, no migration.
- → CLI for terminal-native power users and scripting
- → Desktop for rich interaction, multi-window, visibility
- → Cloud for parallel agents, remote execution, cross-device continuity
- → All three share the same account and model settings
