Add Model Descriptions

Add descriptions for new models available in the HuggingFace router to chat-ui's prod.yaml and dev.yaml. Also flag models that support the OpenAI-compatible reasoning_effort parameter so chat-ui shows the thinking-effort selector for them, and enable artifacts for models with 32B or more total parameters.

Workflow

1. Fetch models from router

   WebFetch https://router.huggingface.co/v1/models

   Extract all model IDs from the response.

2. Read current configuration

   • Read chart/env/prod.yaml
   • Extract model IDs from the MODELS JSON array in envVars

3. Identify missing models Compare router models with prod.yaml. Missing = in router but not in prod.yaml.

   Only operate on these missing models for the rest of the workflow. Never edit, re-flag, or re-describe entries that already exist in prod.yaml / dev.yaml — even if you think their reasoning capability or description could be improved. Existing entries are intentionally curated and may have been hand-tuned for known quirks. Out of scope unless the user explicitly asks for a re-audit.

4. Research each missing model For each missing model, search the web for its specifications:

   • Model architecture (dense, MoE, parameters)
   • Key capabilities (coding, reasoning, vision, multilingual, etc.)
   • Target use cases
   • Whether it's a reasoning model (see step 5)

5. Decide if the model is reasoning-capable A model is "reasoning-capable" for chat-ui purposes if it accepts the OpenAI-style reasoning_effort: low|medium|high parameter via the HF router and meaningfully changes its chain-of-thought depth in response. Whether that holds depends on both the model and the providers serving it — the router is a transparent proxy, so behavior comes from each provider's implementation. Don't decide from the name alone.

   Heuristic shortlist (candidates worth verifying):

   • Name contains gpt-oss, -Thinking, -thinking, -Reasoning, -reasoning, QwQ, R1, MiniMax-M, Kimi-K2-Thinking, cogito-
   • Hybrid models with a thinking switch: DeepSeek V3.1+, GLM-4.5 / 4.6 / 4.7 / 5.x, Qwen3 thinking variants
   • Model card mentions "thinking mode", "reasoning traces", "extended thinking", "test-time compute", or shows <think>...</think> examples

   Skip without further checking:

   • Generic "good at reasoning" marketing copy — every modern LLM claims this. Only flag when reasoning is the mode of operation.
   • Non-thinking siblings (Qwen3-235B-A22B-Instruct-2507 ≠ Qwen3-235B-A22B-Thinking-2507).
   • Translation / vision-only / guard / coder-only models with no documented thinking mode.

   Verify each candidate via provider docs before flagging:

   For each model on the heuristic shortlist, look up its live providers in the /v1/models payload, then check those providers' chat-completions documentation for reasoning_effort, reasoning_content, enable_thinking, or a thinking parameter. If at least one live provider documents it for this model (or for the model family in general), flag it as reasoning-capable. The HF router will proxy the parameter to whichever provider it picks.

   Provider docs to consult (use WebFetch / WebSearch):

   • fireworks-ai: https://docs.fireworks.ai/api-reference/post-chatcompletions
   • groq: https://console.groq.com/docs/reasoning
   • cerebras: https://inference-docs.cerebras.ai/capabilities/reasoning
   • together: https://docs.together.ai/docs/gpt-oss
   • novita: https://novita.ai/docs/guides/llm-interleaved-thinking
   • sambanova: search "sambanova reasoning_effort"
   • deepinfra: https://docs.deepinfra.com/chat/overview
   • nscale, scaleway, ovhcloud, hyperbolic, zai-org, cohere, featherless-ai: search " reasoning_effort" or check their model catalog pages

   If none of the live providers document reasoning support for the model, don't flag it — even if the name pattern-matches. If documentation is ambiguous, lean toward not flagging and mention it in the commit so it can be revisited.

6. Decide if the model gets artifacts Enable artifacts for any new model with 32B or more total parameters by appending "supportsArtifacts": true to its entry. This makes chat-ui instruct the model to emit <artifact> blocks rendered in the side panel.

   • Use the total parameter count, not active parameters. A 35B-A3B MoE qualifies (35B total ≥ 32B) even though only 3B are active.
   • The count is usually in the model name (Qwen3.6-27B, 550B-A55B). When it isn't, use the parameter count found while researching the model in step 4.
   • This is independent of reasoning capability — a model can have both flags, either one, or neither.
   • Models under 32B don't get the flag; users can still enable artifacts per-model via settings overrides.

7. Write descriptions Match existing style:

   • 8-12 words
   • Sentence fragments (no period needed)
   • No articles ("a", "the") unless necessary
   • Focus on: architecture, specialization, key capability

   Examples:

   • "Flagship GLM MoE for coding, reasoning, and agentic tool use."
   • "MoE agent model with multilingual coding and fast outputs."
   • "Vision-language Qwen for documents, GUI agents, and visual reasoning."
   • "Mobile agent for multilingual Android device automation."

8. Update both files Add new models at the TOP of the MODELS array in:

   • chart/env/prod.yaml
   • chart/env/dev.yaml

   Base format:

   { "id": "org/model-name", "description": "Description here." }

   Append "supportsReasoning": true for reasoning-capable models (step 5) and "supportsArtifacts": true for 32B+ models (step 6). A model can carry both:

   {
   	"id": "org/model-name",
   	"description": "Description here.",
   	"supportsReasoning": true,
   	"supportsArtifacts": true
   }

   supportsReasoning is what makes chat-ui render the Thinking-effort dropdown in the chat footer for that model and forward reasoning_effort to the router. supportsArtifacts enables the artifacts side panel for the model.

9. Commit changes In the commit message, mention how many of the new models are reasoning-capable and how many get artifacts so it's easy to review.

   git add chart/env/prod.yaml chart/env/dev.yaml
   git commit -m "feat: add descriptions for N new models from router (M reasoning-capable, K with artifacts)"

Notes

• FP8 variants: describe as "FP8 [base model] for efficient inference with [key capability]". If the base model is reasoning-capable, the FP8 variant is too — flag both. Same for artifacts: quantization doesn't change the parameter count, so a 32B+ base means the FP8 variant gets supportsArtifacts too.
• Vision models: mention "vision-language" and key visual tasks. A vision model can still be reasoning-capable (e.g. Qwen3-VL-*-Thinking) — judge by the same rules.
• Agent models: mention "agent" and automation capabilities.
• Regional models: mention language focus (e.g., "European multilingual", "Southeast Asian").
