Our AI Models

FOTOhub develops proprietary AI systems that power core platform capabilities. These models run on FOTOhub-operated GPU infrastructure, mostly in European data centers (see Infrastructure for the workloads processed in the United States), providing low-latency inference, control over where your data goes, and cost advantages over cloud-only providers.

Model Selection	Dynamically selects the optimal model based on task, quality needs, and cost
Prompt Engineering	Enriches user prompts with model-specific optimizations
Multi-step Workflows	Orchestrates complex tasks requiring sequential operations
Proactive Suggestions	Context-aware recommendations as users navigate the platform
Auto-translation	Real-time translation across 30+ languages

Architecture

                 ├── Intent Classifier (proprietary fine-tuned model)
                 ├── Model Router (availability + cost + quality scoring)
                 ├── Prompt Enhancer (per-model architecture knowledge)
                 ├── Workflow Engine (multi-step task decomposition)

Benchmarks

Metric	Score	Details
Intent accuracy	96.2%	Tested on 10,000+ real user queries across PL/EN/DE
Routing precision	98.7%	Correct model selected for the task type
Prompt enhancement lift	+34%	Quality improvement measured by user satisfaction ratings
Reliability	No published number	Requests route through a multi-model failover chain — if the selected model or engine fails, Gabriel retries against the next healthy candidate and a failed generation is refunded rather than silently dropped

Key Features

Dynamic Model Awareness — Only recommends models that are currently healthy (checked every 60s)
Cost Optimization — Routes to the most cost-effective model for each task
10 Function-Calling Tools — Image, Video, Chat, Music, 3D, Editing, Brand, Tools, Workflows, Q&A
Multi-language — Natively handles PL, EN, DE, FR, ES + 25 more
Zero Extra Cost — Gabriel routing is free; you only pay for the downstream generation

Benchmarks

On the independent DesignArena benchmark (Elo rating, real-world design task quality):

Metric	IDA Q 1.0	Industry Position
DesignArena Elo	1285	5th worldwide
vs. Recraft V4.1 Utility Pro (1245)	+40 Elo	Ahead
vs. Krea 2 Large (1235)	+50 Elo	Ahead
vs. FLUX.2 [pro] (1239)	+46 Elo	Ahead

vs. Imagen 4 Ultra Preview (1233)	+52 Elo	Ahead
vs. GPT Image 2 (1405)	-120 Elo	Behind (top-tier gap)

Prompt Intelligence

Every prompt passes through FOTOhub's own prompt engine before generation — automatic translation to English, expansion of short/casual descriptions into fully detailed scene structure, and verbatim preservation of quoted text and named brands. You write a normal description in any language; the engine handles the rest. See the full breakdown of how this works.

Pricing

Model	Price (USD)	Unit	Meter
IDA Q 1.0 (`ida-q-image`)	See `GET /v1/pricing?model=ida-q-image`	per delivered image	Wallet, by delivered size (`1K`, `HD`, `FULL`)

Priced per delivered image

IDA Q 1.0 is not free: each delivered image is charged to your API wallet at the price of its delivered size, and a failed or cancelled job is refunded. The submit response's cost_usd is the exact amount taken. Current prices: GET /v1/pricing?model=ida-q-image.

Infrastructure

Your files and generated results are stored in the EU, and most proprietary models run on FOTOhub-operated GPU servers in the EU. Image and video analysis — segmentation, matting, background removal, inpainting, depth estimation, OCR, face detection, object tracking and standard video object removal — and textured 3D generation are processed on FOTOhub-operated GPU servers in the United States (Google Cloud), because the required GPU capacity was not available in any EU cloud zone. Those workloads are not EU-hosted; their results are stored in the EU. Remove Object Pro is processed in the EU, unless a job falls back to the standard remover (the job then reports processing_region: "us").

Resource	Specification
Location	Storage: EU. Processing: EU, except image/video analysis tools and textured 3D generation (United States)
Inference	Custom optimized pipeline
Reliability	Multi-model failover — a failed generation retries against a healthy alternative and is refunded rather than left to fail silently. No uptime SLA is published.
Data	GDPR-compliant, no training on user data

Why Self-Hosted

Advantage	Benefit
Cost	60–80% lower per-inference cost vs cloud APIs
Latency	Most inference runs in the EU, close to EU users
Privacy	Proprietary models run on FOTOhub-operated servers, not at third-party model providers (see Infrastructure for where each workload is processed)
Control	Custom quality tuning, no provider deprecation risk
Rate Limits	No external throttling — capacity scales with demand

Comparison

FOTOhub vs. Cloud-Only Platforms

Capability	FOTOhub	Cloud-Only
Music generation (8 min)	$0.20–$0.36 ($0.025–$0.045/min)	$2–5 per track
Voice synthesis	$0.015–$0.030/1K chars	$0.015–$0.030/1K chars
Intelligent routing	Free (Gabriel)	Not available
Model selection	Automatic, 50+ models	Manual, 1 provider
Prompt enhancement	Free, per-model optimized	Not available
Multi-step workflows	Orchestrated by Gabriel	Manual chaining
EU data storage	Default	Extra cost / unavailable

Continuous Improvement

Our proprietary models are continuously improved through architecture upgrades, training data curation, and inference optimization. Updates are deployed seamlessly — no API changes required.
