 Ollama Cloud, OpenRouter, Fireworks, Together AI, Baseten, Ollama, vLLM, and LiteLLM load their available models from the configured provider. New models appear through that discovery without a Sim catalog release. You can also enter a namespaced ID directly, such as `ollama-cloud/deepseek-v4.1-flash`, `openrouter/provider/model`, or `ollama/my-local-model`. Provider prefixes are case-insensitive; the model ID after the prefix keeps its original casing.
 
+### Nebius Token Factory
+
+Select a model beginning with `nebius/` to run an open model through Nebius Token Factory. Sim includes DeepSeek, Kimi, Qwen, and other models in the [Nebius catalog](https://www.sim.ai/models/nebius).
+
+Bring your own Nebius Token Factory API key. On Sim Cloud, a workspace admin can add it under **Workspace settings → BYOK → Nebius**. On self-hosted Sim, provide the key in the Agent block's **API Key** field, using a [secret reference](/platform/credentials). Model features such as image input and structured outputs depend on the selected model.

 ### Jev evaluation models
 
 Select `jev-latest` from TypeSafe in the Agent model selector. Hosted Sim supplies a key and bills model usage through the normal credit system; workspace or organization BYOK keys override the hosted key without model charges. Self-hosted users enter their TypeSafe key in the block. Use `jev-1.13.0` to pin a version or `jev-preview` to follow preview releases. These models use **State** and **Questions** in place of conversational messages. State accepts text or a reference to a JSON object or array. Questions is a JSON object keyed by the answer names you want:

 Use the same clean demo workspace and product theme. Frame the relevant panel with enough context to locate it, and make the result legible at a 390px viewport. Hide unrelated private sidebar content before recording. Keep UI text and controls intact; never generate a different product state to improve a screenshot. Prefer recording at the intended framing over aggressive crops later.
 
+Complete sign-in and credential setup before capturing. Never save a placeholder key and present it as a working connection, or treat a saved key as evidence that the provider accepted it. A model-picker image can show model selection without a connected account; a demonstration of execution must use a working credential and a real result. Keep these production checks out of public copy.
+
 Begin with the task ready to perform, show the action, and hold on its result. Avoid decorative intros, music, title cards, and excessive cursor movement. Keep the headline and important explanation in HTML. Record videos assembled from still screenshots as edited walkthroughs in the production brief; do not describe them as continuous recordings in public copy.
 
 Choose the poster deliberately after reviewing the video. An opening menu, empty state, spinner, or arbitrary first second rarely explains the feature. The media workflow can provide candidate frames, but an editor selects the final timestamp. Preview candidates are not approved assets. Preserve the real aspect ratio inside the shared media frame; do not stretch product UI. Use the same reviewed result frame for the article poster and share image when it works in both contexts.

+# Nebius Token Factory: production record
+
+Status: prepared for publication review. Only `index.mdx` is rendered on the website.
+
+## Story and evidence
+
+One new model provider is a useful standalone update. The article explains the choice it adds and links to setup; it does not repeat the provider's full model and capability inventory.
+
+- [PR #8759](https://github.com/simstudioai/sim/pull/8759), merge `b4c38dfac7e3a0166d8abcd0d3325d0ca4cf1729`, is included in [v0.9.15](https://github.com/simstudioai/sim/releases/tag/v0.9.15).
+- On October 12, 2026, the production Agent block definition returned the Nebius model options, and the [Nebius provider catalog](https://www.sim.ai/models/nebius) returned successfully. The article uses the provider catalog rather than a model page for a different provider.
+- Nebius requires a customer-provided API key. Cloud workspace admins configure it in Workspace settings → BYOK → Nebius; self-hosted users supply it in the Agent block. There is no Nebius-specific plan restriction in the provider or BYOK settings. Model-specific features vary.
+- The source PR records live API acceptance of the model catalog and adapter behavior. This publication adds no new model-execution claim or benchmark.
+- The [Agent guide](https://docs.sim.ai/workflows/blocks/agent) gains a focused Nebius setup section in this PR. Its `#nebius-token-factory` anchor was checked in the rendered docs preview. The article links to the existing guide without the new anchor, so it remains a working destination while the site and docs deploy independently.
+
+## Media provenance
+
+Captured October 12, 2026, in the running self-hosted app from this PR's staging base. A disposable demo workspace uses a synthetic support-ticket prompt. Open the Agent block, search for `nebius` in Model, and inspect the actual options. The reviewed crop includes the Model label, search field, and model list.
+
+Asset: `/changelog/nebius-model-picker-v1.jpg`, 510 × 268 pixels. Direct browser capture, cropped to the relevant panel; no controls or results were generated or altered. The image is displayed at its captured width on desktop to avoid enlarging small interface text. It opens in the existing shared image lightbox.
+
+A still makes the new model choice easier to inspect than a setup video. No credential entry, saved placeholder key, or execution result is depicted. Availability is established separately above. These production notes are not public article copy.
+
+## Publication review
+
+- Review concise article and announcement copy against the released provider.
+- Verify the provider catalog and the new Agent guide anchor.
+- Inspect the article and shared lightbox on desktop and at a real 390px viewport.
+- Run the content audit; use CI for repository test suites.
+- Verify the deployed article, image, index, archive, RSS, and sitemap.
+- Keep publication pending until the production canonical URL passes the publication monitor. A staging deployment is not production publication.
