FuriosaAI

FuriosaAI is a South Korean semiconductor company that designs data-center AI inference chips and the software stack that runs on them. Its second-generation NPU, RNGD, implements a Tensor Contraction Processor architecture on TSMC 5nm and targets LLM, multi-modal and vision inference. The developer surface is software you run yourself rather than a hosted API: Furiosa-LLM ships an OpenAI-compatible server exposing chat, completions, responses, embeddings, score, rerank, models, tokenizer and Prometheus metrics endpoints, and the earlier Furiosa Model Server implements the KServe v2 Predict Protocol and the Triton Model Repository extension over REST and gRPC. Around that sit Python, Go and Rust packages, a furiosa-smi device CLI, container images, an APT/RPM package repository, and a Kubernetes cloud-native toolkit (device plugin, DRA driver, feature discovery, metrics exporter, NPU operator).

FuriosaAI publishes 5 API contracts indexed on the APIs.io network, including Health API, Models API, Predict API, and 2 more. Tagged areas include Artificial Intelligence, Machine Learning, Inference, Semiconductors, and NPU.

FuriosaAI’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, signup flow, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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/furiosa: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

MLOps and AI/ML Infrastructure (LF AI & Data, MLPerf, Kubeflow) standard 17.2 (thin) - -

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

    below is templated on the operator's own host; the documented default is http://localhost:8000/v1. FuriosaAI publishes
    no OpenAPI for this surface - the parameter tables in the serving docs are the contract.

x-base-url-note: All three baseURL values are TEMPLATED on purpose, not missing. FuriosaAI operates no hosted API; both HTTP
  surfaces are servers the customer starts on their own machine. The published defaults are http://localhost:8000/v1 for `furiosa-llm
  serve` and ports 8080 (REST) / 8081 (gRPC) for furiosa-server. repair-api-bases.py reports `no-usable-base` for this repo,
  which is the correct and expected reading of a self-hosted product rather than a defect to repair.

    points at kubeflow/kfserving and triton-inference-server rather than at FuriosaAI, and servers[] is empty. They are nonetheless
    FuriosaAI''s published contract: the furiosa-server README in the same first-party repository states the server is "compliant
    with KFServing''s V2 Dataplane specification and Triton''s Model Repository specification" and lists "OpenAPI specification
    support" as a shipped feature, so the specs describe FuriosaAI''s own product implementing a borrowed protocol verbatim
    - the same reason the .proto files carry upstream provenance headers.'
