Summary

Adds GatewayZ as a new provider with direct Anthropic API support via https://api.gatewayz.ai/v1, enabling access to 10,000+ models through the GatewayZ gateway.

Changes

Provider Configuration

• New provider template with authToken mode and requiresModelMapping: true
• ANTHROPIC_BASE_URL set to https://api.gatewayz.ai/v1 for direct Anthropic messages API

Brand & Theme

• Purple/violet color palette with gateway-themed thinking verbs

TUI/CLI Improvements

• Auto-fill model defaults for GatewayZ in both TUI setup and CLI quick setup
• Custom API key label ("GatewayZ API key")

Inconsistent capitalization: "Gatewayz API" should be "GatewayZ API" to match the brand name used everywhere else in the codebase (e.g., line 81 "GatewayZ — Your Gateway to AI").

Suggested change

	'Access to 10,000 models via Gatewayz API',
	'Access to 10,000 models via GatewayZ API',

[Copilot]

The GatewayZ model defaults are duplicated in three places: here in getDefaultModels, in ModelConfigScreen.tsx getPlaceholder, and in modelOverrides.ts PROVIDER_MODEL_DEFAULTS. This duplication creates a maintenance burden and risk of inconsistency. Consider centralizing these defaults in a shared constant, possibly in the provider definition itself or in a dedicated constants file.

Suggested change

	const getDefaultModels = (key?: string | null): { opus: string; sonnet: string; haiku: string } => {
	if (key === 'gatewayz') {
	return {
	opus: 'claude-opus-4-5-20251101',
	sonnet: 'claude-sonnet-4-20250514',
	haiku: 'claude-haiku-3-5-20241022',
	};
	const GATEWAYZ_DEFAULT_MODELS: { opus: string; sonnet: string; haiku: string } = {
	opus: 'claude-opus-4-5-20251101',
	sonnet: 'claude-sonnet-4-20250514',
	haiku: 'claude-haiku-3-5-20241022',
	};
	const getDefaultModels = (key?: string | null): { opus: string; sonnet: string; haiku: string } => {
	if (key === 'gatewayz') {
	return GATEWAYZ_DEFAULT_MODELS;

[Copilot]

The comment references "OpenRouter, LiteLLM" as examples but should be updated to include GatewayZ or be more generic since GatewayZ also requires model mapping. Consider updating to "providers that require model mapping" or explicitly listing all applicable providers.

Suggested change

	* Ensure model mapping for providers that require it (e.g., OpenRouter, LiteLLM)
	* Ensure model mapping for providers that require explicit model mapping

[Copilot]

The comments "(for OpenRouter)" on these model mapping options are outdated. These flags now apply to multiple providers that require model mapping, including GatewayZ. Consider updating to "(for providers requiring model mapping)" or removing the parenthetical entirely since the usage is documented elsewhere.

Suggested change

	--model-sonnet <name> Map to sonnet model (for OpenRouter)
	--model-opus <name> Map to opus model (for OpenRouter)
	--model-haiku <name> Map to haiku model (for OpenRouter)
	--model-sonnet <name> Map to sonnet model (for providers requiring model mapping)
	--model-opus <name> Map to opus model (for providers requiring model mapping)
	--model-haiku <name> Map to haiku model (for providers requiring model mapping)

[Copilot]

The envVarName parameter expects an environment variable name (like ANTHROPIC_AUTH_TOKEN or ANTHROPIC_API_KEY), but this change passes provider?.apiKeyLabel which contains human-readable text like "GatewayZ API key". This will display incorrectly in the MaskedInput component where envVarName is shown as a label.

The original logic should be preserved: provider?.authMode === 'authToken' ? 'ANTHROPIC_AUTH_TOKEN' : 'ANTHROPIC_API_KEY'

Suggested change

	envVarName={provider?.apiKeyLabel || 'API Key'}
	envVarName={provider?.authMode === 'authToken' ? 'ANTHROPIC_AUTH_TOKEN' : 'ANTHROPIC_API_KEY'}

Addressing Copilot Review Comments

Fixed ✅

1. Capitalization: Changed "Gatewayz API" to "GatewayZ API" in providers.ts
2. Comment update: Changed modelOverrides.ts comment from "OpenRouter, LiteLLM" to "providers that require explicit model mapping"
3. README update: Changed model flag comments from "(for OpenRouter)" to "(for providers requiring model mapping)"

Intentionally Kept ⚠️

4. envVarName using apiKeyLabel: This is an intentional UX improvement - showing "GatewayZ API key:" is more user-friendly than the generic "ANTHROPIC_AUTH_TOKEN:". The parameter name is slightly misleading but the functionality is correct and provides better user experience.

Not Addressed (Low Priority) ℹ️

5. Model defaults duplication: Copilot suggested centralizing the model defaults across app.tsx, ModelConfigScreen.tsx, and modelOverrides.ts. This would be a nice refactor for a future PR but is not critical - the current code works correctly and consistently.
