The same model can have very different prices, cache-read costs, throughput, and reliability across OpenRouter providers. This plugin helps DeepSeek Harness users find a more cost-efficient, better-fit provider and switch in one click.

It combines quantization, speed, cache-heavy pricing, context, and uptime into a Top 5 for the current model. You no longer need to compare providers or create presets by hand: clicking a row updates both the active session and default model.

Core value: reduce avoidable inference spend without changing models, while finding a practical balance between cost, speed, and reliability.

The recommendations can surface same-model routes priced well below the model vendor's own API. For example, the StreamLake deepseek-v4-flash-0731 quote shown on 2026-08-25 compares with DeepSeek's peak-hour Flash pricing as follows, using 1 USD ≈ 6.7225 CNY:

Per 1M tokens	StreamLake	DeepSeek peak hours	Estimated reduction
Input (cache hit)	$0.0028 ≈ ¥0.0188	¥0.10	81.2%
Input (cache miss)	$0.088 ≈ ¥0.5916	¥3.00	80.3%
Output	$0.064 ≈ ¥0.4302	¥9.00	95.2%
Code Agent weighted estimate (2% / 8% / 90%)	≈ ¥0.0632	≈ ¥0.8700	92.7%

This is a point-in-time example, not a guarantee of persistent savings. OpenRouter provider quotes, DeepSeek pricing, and FX rates can all change; check the live recommendations and DeepSeek's official pricing page. FX reference: USD/CNY on 2026-08-25.

Highlights

• Compare input, output, and cache-read prices to help reduce spend.
• Find the best fit rather than blindly choosing the cheapest endpoint.
• Model-aware ranking without a hard-coded model catalog.
• Best overall, price-first, speed-first, and context-first strategies.
• Code Agent price blend: 2% input, 8% output, 90% cache-read by default.
• Continuous, gentle 30-minute uptime penalties and hard filtering for unavailable endpoints.
• One-click switching for the active session and deployment default.
• Linked percentage sliders with locks; each group always totals 100%.
• Reuses DSH credential references; API keys never reach the browser.
• Read-only recommendation tool and approval-gated agent switching tool.
• Live Chinese/English UI following the DSH locale.

Uptime is OpenRouter's trailing 30-minute statistic. Fresh failures, rate limits, and recoveries may be detected with a delay; this is not an active health probe.

Install

Requirements: DSH 0.1.1-rc.2 or newer, Node.js ^22.19.0 or >=24, and an OpenRouter provider/API key configured in DSH Settings → Models.

dsh plugin --profile web add dsh-openrouter-provider-advisor@latest

Hard-refresh (Cmd/Ctrl + Shift + R). Restart dsh web if its Host half was already running.

# Update
dsh plugin --profile web add dsh-openrouter-provider-advisor@latest

# Remove
dsh plugin --profile web remove dsh-openrouter-provider-advisor

Use

Open a normal DSH session, click OpenRouter Providers in the left footer, pick a model and strategy, then click a provider. The next request uses @preset/<model>-<provider>.

create/update OpenRouter preset
        ↓
upsert DSH OpenRouter model entry
        ↓
session.selectModel
        ↓
save the DSH default model

An already assembled request is not rewritten mid-flight.

Ranking

Best overall defaults to 30% quantization, 30% speed, 30% price, and 10% context. Cache-heavy cost is:

cost = input price × 2% + output price × 8% + cache-read price × 90%

OpenRouter trailing 30-minute uptime	Score retained
≥99.5%	100%
99–99.5%	97%–100% (continuous)
98–99%	90%–97% (continuous)
95–98%	75%–90% (continuous)
90–95%	50%–75% (continuous)
<90%	10%–50% (continuous)
Missing	85%

Endpoints with nonzero status are excluded. Configured penalties ramp in across five percentage points below the threshold and combine with the stricter general curve.

Credentials and security

• Reuses the selected DSH OpenRouter profile's apiKeyEnv, with OPENROUTER_API_KEY as a compatibility fallback reference.
• Credential values stay Host-only and never appear in client code, HTTP responses, or settings.
• Mutation routes accept same-origin JSON only and cap bodies at 64KB.
• Reads time out after 15 seconds; preset writes after 30 seconds.
• Agent-initiated switching always uses native DSH approval.
• The plugin does not read conversation messages, history, or workspace files.

Data sources and limits

Only official OpenRouter APIs are used: /models, /models/{id}/endpoints, and /presets/{slug}/chat/completions. The plugin does not scrape product pages. OpenRouter statistics may lag fresh upstream failures and recoveries.

Development

git clone https://github.com/xuan666-lab/dsh-openrouter-provider-advisor.git
cd dsh-openrouter-provider-advisor
npm install
npm run verify
npm pack --dry-run

Automated tests stop before a real provider click because switching creates or versions an actual OpenRouter preset.
