GPU compute
for research, agents and humans.
Cloud-agnostic GPU compute for your existing code. Deploy Bash scripts, Docker containers or Python environments through your agent or the CLI.
What is this?
This illustrates a radio pulse from a pulsar: a spinning neutron star whose radio beam sweeps past Earth like a lighthouse. The first pulsar was discovered in Cambridge in 1967.
As a pulse travels through plasma in space, lower radio frequencies arrive later than higher ones. This spreads the signal out in time: dispersion. Astronomers search for these pulses by dedispersing the data, aligning the frequency channels just as you do when you scroll.
Many possible alignments can be checked in parallel, making the search a natural fit for GPUs. C3’s first scientific workload was a search for radio signals like these.
claude mcp add --transport http c3 https://api.cthree.cloud/mcpThen run /mcp in Claude Code and choose Authenticate for C3.
You set the work.
C3 runs it.
Like Slurm, but your laptop is the login node and the world is your GPU cluster.
Run scripts through your agent or the CLI, with logs and a shareable page for every job.

The infrastructure layer for automated research
We’re building the scheduling layer between research agents and GPU compute. Our neural scheduler coordinates jobs across clouds, matching changing workloads to available capacity so your agents can keep experimenting.
18.5× lower GPU cost
25 agents · 2,038 jobs
Measured on one discovery loop against an always-on GPU per agent, before the neural solver. Savings vary by workload.
Your code. No custom functions.
Docker, Bash or Python.
Deploy Docker containers, run Bash scripts or use Python environments. Keep your code and dependencies without platform-specific function wrappers.

- Bash
- Python
Choose your cloud.
Let C3 find available compute, or pick a provider yourself. Keep the same workflow when you switch clouds.
- GCP
Pay for the work.
Scale independent GPU jobs with demand. Pay per second, with logs and results you can inspect.
Run your first job.
Free credits to start. Per-second billing.
