Deploy Gemma 4 31B-it in One Click: 4-bit, 8-bit, 16-bit Production API
Gemma 4 31B is Google’s high-quality 31B-class instruction model — designed to deliver strong reasoning, coding, multilingual understanding, and reliable instruction-following while remaining lighter and more cost-efficient than larger 70B-class models. With 4-bit or AWQ-style quantization, it can be deployed on modern GPUs with lower VRAM requirements, making it a strong quality-per-dollar choice for production AI applications.
Where is Gemma 4 31B useful for you?
Internal coding copilot — strong code generation, debugging, refactoring, and explanation capabilities for developer workflows.
RAG over private documents — good instruction-following helps keep answers grounded in retrieved context from your internal knowledge base.
Structured data extraction — reliable for JSON outputs, summaries, classifications, and schema-based extraction from documents, forms, invoices, and product data.
Multilingual support automation — useful for handling multilingual customer conversations, support tickets, and documentation workflows.
Multi-step agent workflows — capable of planning, tool calls, task decomposition, and workflow automation with lower serving costs than larger models.
Enterprise chat assistants — ideal for internal assistants, customer support bots, technical Q&A, documentation search, and domain-specific copilots.
That being said, deploying it on a GPU server shouldn’t mean fighting CUDA versions, broken wheels, flash-attention builds, OOMs, and “works locally, fails on the server”.
This page lets you deploy Gemma 4 31B-it on our GPU servers with a single click and get a production-ready, OpenAI-compatible API endpoint (with auth, logs, metrics, and sane defaults).
What you get
OpenAI-compatible endpoint (
/v1/chat/completions, streaming supported)Dedicated vLLM URL with HTTPS + API key for security
Observability: latency, logs, tokens/sec, GPU memory, error rate

Step 2: Choose your LLM for Deployment
On the Dashboard, click "Deploy Model"
Select your model to deploy from the catalogue
Correctly set your LLM deployment options
- Model Precision: Select the precision level for the model weights. Lower-bit precision reduces GPU memory usage and can improve speed, while higher precision may preserve better output quality.
| Precision | VRAM needed | Quality | Speed | When to use |
|---|---|---|---|---|
| 4-bit | ~24GB | Good | Fastest | Cost-sensitive, high volume |
| 8-bit | ~40GB | Better | Fast | Best quality/cost balance |
| 16-bit | ~64GB | Best | Slower | Maximum quality |
Throughput Requirements: Set how many requests the model should handle at the same time per GPU. Higher concurrency can improve throughput but may require more GPU memory.
Request Sizing: Choose the maximum number of tokens you need to process in a single request. Higher context windows are useful for large documents or multi-turn chats but increase memory usage.
Step 3: Choose the right GPU
Gemma 4 31B is inference-friendly, but your experience depends on VRAM, context length, and precision.
Recommended minimum: 32 GB VRAM
Good baseline: 48 GB VRAM
High throughput / heavy batching: 80 GB+ VRAM
Step 4: Choose GPU count and Datacenter
Number of GPUs
Choose the GPU count based on your model size and expected traffic. Larger models or higher concurrency usually need more GPUs.
Increasing GPUs can improve throughput and reduce latency, but it also increases deployment cost.
Datacenter
Select a datacenter close to your users to reduce network latency and improve response times.
Choose a region that meets your data residency, availability, and compliance requirements.
Step 5: Choose pricing for your deployment
On-Demand 15 : You get billed in increments of 15-minutes
On-Demand 30 : You get billed in increments of 30-minutes. Choose this as it's cheaper on a per-minute basis.
Hit Deploy !
It takes some time to find the GPU resources and allocate them for you.
After that provisioning of the selected model and the API starts, which can further take 5-15 mins depending on the size of model.
At last, you will see a "Model Ready" indicator which indicates that it's ready for use.
