Why One AI Model Isn't Enough

Different AI models excel at different things. Claude is exceptional at reasoning and complex architectures. GPT-4o is fast and reliable. DeepSeek offers incredible value. Groq delivers blazing inference speed. Mistral handles European languages beautifully.

So why would you lock yourself into just one?

With VULK's BYOM (Bring Your Own Model) system, you don't have to choose. Connect your own API keys and use whatever model fits your project — without spending a single VULK credit.

Supported Providers

VULK supports 8 AI providers natively, plus any OpenAI-compatible endpoint:

Provider	Key Models	Best For
OpenAI	GPT-4o, GPT-4o-mini, o3	General-purpose, fast iteration
DeepSeek	DeepSeek V3, DeepSeek R1	Cost-effective, strong reasoning
Groq	Llama 3.3 70B, Mixtral	Ultra-fast inference (500+ tok/s)
Mistral	Mistral Large, Codestral	European languages, code generation
Together AI	Llama 3.1 405B, Qwen 2.5	Large open-source models
Fireworks	FireFunction, Llama 3.3	Production-grade, low latency
Ollama	Any local model	Privacy-first, offline development
Custom	Any OpenAI-compatible API	Self-hosted, enterprise setups

How It Works

Setting up BYOM takes about 30 seconds:

Go to Settings → API Keys in your VULK dashboard
Select your provider from the dropdown
Paste your API key — it's validated instantly
Choose your model from the auto-populated list
Start building — all generations route through your key

Your API key is encrypted with AES-256-GCM before storage. We never log your requests or responses. The key is only decrypted at the moment of making the API call.

Zero Credits, Full Power

When you use BYOM, your generations go directly to the provider's API. VULK doesn't charge credits for BYOM generations — you only pay the provider's token costs.

This means:

No credit limits on generation length or complexity
No throttling based on your VULK plan
Full model selection — use any model your provider offers
Same VULK features — preview, deployment, file management all work the same

The Smart Routing Architecture

VULK's model router is intelligent about how it uses your key:

User Prompt → Intent Analysis → Model Router
                                    ├── Config files → Fast model (saves cost)
                                    ├── UI components → Medium model (balanced)
                                    └── Auth/Security → Best model (accuracy)

Even with BYOM, VULK's smart routing can optimize your costs by using lighter models for simpler files — if you enable it in settings.

Key Validation

Before saving your key, VULK makes a lightweight validation request to confirm:

The key is valid and active
The key has sufficient permissions
The selected model is accessible

If validation fails, you get a clear error message explaining what to fix — no guessing.

Who Is BYOM For?

Power users who generate dozens of apps per day and want predictable costs
Enterprise teams with existing AI contracts and volume discounts
Privacy-conscious developers who want to use local models via Ollama
Open-source enthusiasts who prefer running Llama, Qwen, or Mixtral
Cost optimizers who found a provider with better pricing for their usage

Getting Started

BYOM is available on all VULK plans, including Free. Head to Settings → API Keys, connect your provider, and start building with any AI model you want.

Your keys. Your models. Your apps. Zero VULK credits.
