Positron

Positron AI is a US-based generative-AI hardware company founded in 2023 and headquartered in Reno, Nevada, building purpose-built Transformer inference accelerators as an alternative to GPU-based inference infrastructure. Its shipping product, Atlas, is a rack inference appliance built on eight in-house Archer accelerators (256 GB HBM) and dual AMD EPYC Genoa processors, with the next-generation Asimov silicon and Titan system slated for 2027. Positron exposes its inference fleet through "Olivaw", a serving and administration layer that publishes two documented HTTP APIs: an OpenAI-compatible completions API (models, chat completions, text completions, with server-sent-event streaming) so existing OpenAI client code can be repointed at a Positron endpoint, and an administrative API for managing models, service nodes, users, and access tokens on an appliance or hosted cluster. The company raised a $230M Series B in February 2026 at a valuation above $1B from ARENA, Jump Trading, Unless, the Qatar Investment Authority, Arm, Helena, DFJ Growth, Atreides, Valor, Resilience Reserve, Flume Ventures and 1517 Fund.

Positron publishes 5 APIs on the APIs.io network, including Access Tokens API, Completion API, Models API, and 2 more. Tagged areas include Artificial Intelligence, AI Inference, inference-hardware, AI Accelerators, and Large Language Models.

Positron’s developer surface includes documentation, API reference, getting-started guide, support, changelog, authentication, and 25 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/positron: open an issue to ask a question, or submit a pull request to add artifacts.
