Tier Configuration

The SDK provides utilities for managing account tier differences in video and image generation.

Account Tiers

Google Labs offers three subscription tiers:

Feature	Free	Pro	Ultra
Video Modes	basic	quality, fast	quality, fast
Default Video Mode	fast	fast	quality
PaygateTier	PAYGATE_TIER_ONE	PAYGATE_TIER_TWO	PAYGATE_TIER_TWO
HD Upscaling	No	Yes	Yes
Quality Mode	No	Yes	Yes
Max Images/Batch	4	4	4

Tier Utilities

Import tier configuration utilities:

import {
  getTierCapabilities,
  getEffectiveVideoMode,
  getVideoApiConfig,
  getImageApiConfig,
  isFeatureSupported,
} from '@getvrex/glabs-sdk';

Get Tier Capabilities

const capabilities = getTierCapabilities('pro');
 
console.log(capabilities.supportedVideoModes);  // ['quality', 'fast']
console.log(capabilities.defaultVideoMode);     // 'fast'
console.log(capabilities.paygateTier);          // 'PAYGATE_TIER_TWO'
console.log(capabilities.supportsUpsample);     // true
console.log(capabilities.supportsQualityMode);  // true
console.log(capabilities.maxImageGenerationCount); // 4

Get Effective Video Mode

Returns the actual mode that will be used based on tier restrictions:

// Pro account requesting quality mode
const mode = getEffectiveVideoMode('pro', 'quality');
// Returns: 'quality' (supported)
 
// Pro account with no mode specified
const defaultMode = getEffectiveVideoMode('pro');
// Returns: 'fast' (tier default)

Get Video API Config

Get all configuration needed for a video API request:

const config = getVideoApiConfig(
  'text-to-video',  // Generation type
  'pro',            // Account tier
  '16:9',           // Aspect ratio
  'fast'            // Video mode
);
 
console.log(config.videoModelKey);      // 'veo_3_1_t2v_fast_ultra'
console.log(config.userPaygateTier);    // 'PAYGATE_TIER_TWO'
console.log(config.effectiveVideoMode); // 'fast'
console.log(config.aspectRatioEnum);    // 'VIDEO_ASPECT_RATIO_LANDSCAPE'

Get Image API Config

const config = getImageApiConfig(
  'pro',           // Account tier
  '16:9',          // Aspect ratio
  'nanobanana'     // Model
);
 
console.log(config.imageModelName);  // 'GEM_PIX'
console.log(config.aspectRatioEnum); // 'IMAGE_ASPECT_RATIO_LANDSCAPE'

Check Feature Support

// Check if HD upscaling is supported
const upsampleSupport = isFeatureSupported('upsample', 'pro', '16:9');
console.log(upsampleSupport.supported); // true
 
// HD upscaling only works with 16:9
const portraitUpsample = isFeatureSupported('upsample', 'pro', '9:16');
console.log(portraitUpsample.supported); // false
console.log(portraitUpsample.reason);    // 'HD upscaling only supports 16:9 landscape videos'
 
// Check quality mode support
const qualitySupport = isFeatureSupported('quality_mode', 'pro');
console.log(qualitySupport.supported); // true

Video Generation Types

Type	Description
`text-to-video`	Generate from text prompt
`image-to-video`	Generate from first frame image
`image-to-video-fl`	Generate from first and last frame images
`extend`	Extend existing video
`reshoot`	Camera control reshoot
`upsample`	HD upscaling (1080p)
`reference-images`	Multi-image reference video

Video Model Keys

The SDK automatically selects the correct model based on generation type, tier, mode, and aspect ratio.

Text-to-Video Models

Tier	Mode	Model Key
Pro/Ultra	fast	`veo_3_1_t2v_fast_ultra`
Pro/Ultra	quality	`veo_3_1_t2v`

Image-to-Video Models

Tier	Mode	Aspect	Model Key
Pro/Ultra	fast	16:9, 1:1	`veo_3_1_i2v_s_fast_ultra`
Pro/Ultra	fast	9:16	`veo_3_1_i2v_s_fast_portrait_ultra`
Pro/Ultra	quality	16:9, 1:1	`veo_3_1_i2v_s`
Pro/Ultra	quality	9:16	`veo_3_1_i2v_s_portrait`

Camera Control Models

Aspect	Model Key
16:9	`veo_3_0_reshoot_landscape`
9:16	`veo_3_0_reshoot_portrait`
1:1	`veo_3_0_reshoot_square`

Reference Images Models

Tier	Model Key
Pro	`veo_3_0_r2v_fast`
Ultra	`veo_3_0_r2v_fast_ultra`

Upscale Model

All tiers use veo_2_1080p_upsampler_8s for HD upscaling.

Aspect Ratio Enums

Video Aspect Ratios

Ratio	Enum Value
