Description

End-to-end support for OpenAI Native service tiers (default, flex, priority):

What’s included:

Types
- Add ServiceTier and tiered pricing fields to ModelInfo
- Allow per-model allowedServiceTiers and serviceTierPricing
Provider settings
- Add openAiNativeServiceTier to the OpenAI Native schema in provider-settings
Model catalog
- Populate allowedServiceTiers and serviceTierPricing for applicable models in openai.ts
OpenAI Native provider
- Include service_tier in Responses API requests when requested and supported; retry without it on 400 invalid/unsupported tier
- Capture resolved response.service_tier from the stream and derive effective pricing
- Apply tiered pricing in usage cost computation without changing shared cost logic
- Include service_tier in non‑streaming completePrompt() calls
- Files: openai-native.ts
UI (webview)
- Add “Service tier” dropdown with an info tooltip; shown only when the selected model supports flex/priority
- Add a tiered pricing table and hide the old single‑line price bullets when the table is shown
- Files: OpenAI.tsx, ApiOptions.tsx, ModelInfoView.tsx
Tests
- New unit tests covering request body tier inclusion, retry on unsupported tier, capturing service_tier from the stream, and tiered pricing cost computation
- File: openai-native-service-tier.spec.ts

Why:

Enables users to explicitly select “flex” (lower cost, higher latency) or “priority” (faster processing) where supported.
Ensures usage/cost reporting reflects the actual tier used by OpenAI’s Responses API.

Test Procedure

Automated:

Run backend tests:
- cd src && npx vitest run api/providers/__tests__/openai-native-service-tier.spec.ts
Run UI tests:
- cd webview-ui && npx vitest run

Manual:

Settings → select provider “OpenAI (openai-native)”
Choose a model with tier support (e.g., gpt-5-2025-08-07, o4-mini, o3)
Verify:
- “Service tier” dropdown is visible and includes only supported non‑standard tiers
- When table is shown, single-line price bullets are hidden
- Tiered pricing table shows “Standard”, plus Flex/Priority with per‑1M token prices
Choose a model without tier support → no dropdown and no table; single‑line prices remain
Make a request and confirm usage cost aligns with chosen/resolved tier.

Pre-Submission Checklist

Scope: Changes focused on OpenAI Native service tiers end‑to‑end
Self-Review: Code and UX paths verified
Testing: Added/updated unit tests and ran UI tests
Docs Impact: None required in this repo

Additional Notes

Costing relies on applyServiceTierPricing to produce an effective ModelInfo before calling shared cost helpers.
Request fallback behavior gracefully handles unsupported/invalid service_tier.

+	const allowedTiers =
+		(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority") ?? []


The nullish coalescing operator (??) is redundant since the logical OR (||) already provides an empty array as fallback. Remove the ?? [] at the end.

Suggested change

const allowedTiers =

(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority") ?? []

User‐facing text in the tiered pricing table header and column labels is hard-coded. Consider internationalizing these strings using t() for consistency.

Thank you for your contribution! I've reviewed the changes and found several critical issues that need attention before this PR can be merged.

The main concern is that this appears to be an incomplete implementation - only the UI components have been added, but all the backend support mentioned in the PR description is missing.

roomote · 2025-09-03T22:25:57Z

+	// Show tiered pricing table for OpenAI Native when model supports non-standard tiers
+	const allowedTiers =
+		(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority") ?? []


The nullish coalescing operator (??) is redundant here since the logical OR (||) already provides an empty array as fallback.

Suggested change

(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority") ?? []

const allowedTiers =

(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority")

+	// Show tiered pricing table for OpenAI Native when model supports non-standard tiers
+	const allowedTiers =
+		(modelInfo?.allowedServiceTiers || []).filter((tier) => tier === "flex" || tier === "priority") ?? []


Critical issue: The properties allowedServiceTiers and serviceTierPricing don't exist in the ModelInfo type. This will cause TypeScript compilation errors. The type definitions need to be added to packages/types/src/model.ts first.

+			{shouldShowTierPricingTable && (
+				<div className="mt-2">
+					<div className="text-xs text-vscode-descriptionForeground mb-1">
+						Pricing by service tier (price per 1M tokens)


This hardcoded text needs internationalization. Consider using:

Suggested change

Pricing by service tier (price per 1M tokens)

<div className="text-xs text-vscode-descriptionForeground mb-1">

{t('settings:modelInfo.tierPricingHeader')}

</div>

roomote · 2025-09-03T22:25:57Z

webview-ui/src/components/settings/ModelInfoView.tsx

+									<tr className="border-t border-vscode-dropdown-border/60">
+										<td className="px-3 py-1.5">Flex</td>
+										<td className="px-3 py-1.5 text-right">
+											{fmt(tierPricing?.flex?.inputPrice ?? modelInfo?.inputPrice)}


The tier pricing fallback logic is duplicated 6 times across this component. Could we extract this into a helper function? For example:

const getTierPrice = (tier: string, priceType: 'inputPrice' | 'outputPrice' | 'cacheReadsPrice') => { return tierPricing?.[tier]?.[priceType] ?? modelInfo?.[priceType] }

Then use it like: {fmt(getTierPrice('flex', 'inputPrice'))}

+						<div className="flex items-center gap-1">
+							<label className="block font-medium mb-1">Service tier</label>


These UI strings need internationalization. The label "Service tier" and the dropdown options "Standard", "Flex", "Priority" should use translation keys:

Suggested change

<label className="block font-medium mb-1">Service tier</label>

<label className="block font-medium mb-1">{t("settings:providers.serviceTier")}</label>

roomote · 2025-09-03T22:25:57Z

webview-ui/src/components/settings/providers/OpenAI.tsx

+						</div>
+
+						<Select
+							value={apiConfiguration.openAiNativeServiceTier || "default"}


Critical issue: The property openAiNativeServiceTier doesn't exist in ProviderSettings type. This needs to be added to packages/types/src/provider-settings.ts in the openAiNativeSchema.

roomote · 2025-09-03T22:25:58Z

webview-ui/src/components/settings/ApiOptions.tsx

+				<OpenAI
+					apiConfiguration={apiConfiguration}
+					setApiConfigurationField={setApiConfigurationField}
+					selectedModelInfo={selectedModelInfo}


Is this implementation complete? The UI is passing selectedModelInfo to the OpenAI component, but there's no backend implementation to actually use the service tier selection. The following files mentioned in the PR description are missing their implementations:

packages/types/src/providers/openai.ts - No service tier support

src/api/providers/openai-native.ts - No service tier handling

src/api/providers/__tests__/openai-native-service-tier.spec.ts - Test file doesn't exist

Without these backend changes, the UI will set the service tier but it won't actually be used in API requests.
