    Open-weight Nemotron, DeepSeek, GLM and Kimi models are callable by id and hosted by Perplexity; the Router API is a further open-weight catalogue in private preview.

    Source retrieved 2026-09-02

  • Pickaxe Yes

    Open-weight families such as GLM, DeepSeek and Kimi are offered in the catalogue, but they run on Pickaxe's infrastructure and are billed in credits, so you are not running the weights yourself.

    Source retrieved 2026-09-09

  • PolyAI Qualified

    The model catalogue enumerates only Raven, OpenAI and Amazon Bedrock (Claude, Nova) with no open-weight option, but you can attach your own LLM endpoint.

    Source retrieved 2026-09-02

    Open-weight models reachable through the OpenRouter integration; the vendor also hosts LLaMA-family models in its own cloud

    Source retrieved 2026-09-02

  • Replit Agent Qualified

    Open-source model providers are a real but second-class category for Agent: they exist as a provider policy and are off unless an admin turns them on.

    Source retrieved 2026-09-02

  • Retell AI Qualified

    The hosted model menu enumerates only OpenAI, Anthropic and Google models, so no open-weight model is offered, but the custom LLM WebSocket path exists precisely so you can host one yourself.

    Source retrieved 2026-09-02

  • Rox Qualified

    Rox offers to integrate a customer's own trained models on request; it names no open-weight model and exposes no way to run one from the product.

    Source retrieved 2026-09-03

  • Salesforce Agentforce Qualified

    The Salesforce-managed model list names only Anthropic, OpenAI/Azure OpenAI, Google Vertex, Amazon and NVIDIA (beta), with no Llama or Mistral, so open-weight models arrive only through the customer's own BYOLLM connection.

    Source retrieved 2026-09-03

    Source retrieved 2026-09-03

  • StackAI Yes

    Open-weight models are reachable two ways: Llama-family models through a Cerebras key, and any model you host yourself through the Local provider connection.

    Source retrieved 2026-09-09

  • Telnyx Voice AI Agents Yes

    Open-weight Qwen and Moonshot Kimi families run on Telnyx's own GPUs and are the recommended default for assistants, so prompt and response generation never leaves Telnyx infrastructure.

    Source retrieved 2026-09-09

  • UiPath Agent Builder Qualified

    No open-weight family appears in the closed docs table of models supported for Agents, which lists only Google, OpenAI and Anthropic; open-source models are offered only for on-premises Automation Suite, plus a generic connector for any OpenAI-V1-compatible endpoint.

    Source retrieved 2026-09-03

    Open-weight models are hosted for you through Fireworks AI, and an Auto (Open-weights) router picks between them; Llama is absent from that enumerated table.

    Source retrieved 2026-09-03

  • Zed Yes

    Open-weight models run through llama.cpp, Ollama, LM Studio or any local OpenAI-compatible server, feeding the Zed Agent and Inline Assistant.

    Source retrieved 2026-09-03

  • Zencoder Qualified

    Open-weight models are not sold in the managed catalogue; you reach them by declaring your own Ollama or vLLM endpoint in settings.json and paying for that inference yourself.

The population

126 listings in this index are Published. This is the population as of 2026-09-16. 126 of the 126 published listings in this index carry a settled answer for “Open models”. That row asks: Can it run on open-weight models? Every listing in the index is settled on this row, so nothing is left out.

Findings

  1. 53 of the 126 settled listings answer “Yes” for “Open models”. That is 42% of the settled set.

  2. 22 of the 126 settled listings answer “Qualified” for “Open models”. That is 17% of the settled set.

  3. 32 of the 126 settled listings answer “No” for “Open models”. That is 25% of the settled set.

  4. 19 of the 126 settled listings answer “Not established” for “Open models”. That is 15% of the settled set.

1 of those yes answers is StackAI, which still answers yes for “Open models”. Its listing carries the stored answer and links to the source recorded for it. This is one worked example, not an independent audit of every source in the census.

What we counted, and how

Each figure above is a count over the “Open models” row of the listing datasheet, taken from the same stored answer the listing page renders. The denominator is the 126 listings whose answer is settled, meaning one of yes, qualified, no, does not apply, not established. On this row that is the whole index, because every listing has a recognised stored answer. Every number here is stored with the read-only query that reproduces it and re-run every sixty seconds against the live corpus, so a figure that stops reproducing surfaces as drift rather than as a stale sentence nobody notices. Our full method covers how a datasheet row is settled in the first place.

Limitations

This counts stored datasheet answers, not independently tested capabilities. A sourced answer can record a vendor statement or our reading of published evidence; this census does not re-fetch those sources. “Not established” means we have not established an answer. That can reflect vendor nondisclosure, blocked evidence, or unfinished research, not a no. An absent or unrecognised answer is excluded rather than treated as a researched finding. The figures are restated when the stored corpus changes; the date above is the count used for this published version, not a new verification of the vendors.
