Fluidstack

Fluidstack is an AI cloud platform that builds and operates high-performance, single-tenant GPU clusters for top AI labs, governments, and enterprises. Founded in 2017 out of Oxford University and now headquartered in New York City, Fluidstack manages more than 100,000 GPUs across its global network and has been selected by customers including Anthropic, Meta, Mistral, Poolside, Black Forest Labs, and Character.AI. Its core offering combines on-demand bare-metal GPU clusters (including thousands of NVIDIA H200s with InfiniBand) with managed Kubernetes and managed Slurm orchestration layers, Lighthouse observability, and human-on-call site reliability. Fluidstack exposes a global REST Management API (api.atlas.fluidstack.io/api/v1alpha1) and the fluidctl CLI for managing organizations, projects, regions, clusters, instances, members, invitations, and SSH keys. The platform is GDPR, SOC 2 Type 2, and ISO 27001 certified, and was awarded ClusterMAX Gold by SemiAnalysis.

Fluidstack publishes 7 APIs on the APIs.io network, including Clusters API, Instances API, Invitations API, and 4 more. Tagged areas include Artificial Intelligence, GPU, Cloud, Compute, and Infrastructure.

Fluidstack’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, and 15 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/fluidstack: open an issue to ask a question, or submit a pull request to add artifacts.
