Gemma 4 31B Guide: Capabilities, Use Cases & API Access

Building multilingual applications that serve diverse user bases often forces developers into a maze of conflicting API formats, provider-specific SDKs, and fragmented billing dashboards. Every new language or region adds complexity, especially when you need high-quality Arabic language support alongside mainstream English capabilities. Rather than maintaining separate integrations for each model provider, engineering teams need a single gateway that normalizes access, normalizes billing, and preserves the freedom to switch models without rewriting client code.

The LLM Resayil Portal answers that need. Hosted in the USA, the portal is an OpenAI and Anthropic compatible LLM API with Arabic language support. It exposes 33 active models through one unified base URL, giving developers the ability to route traffic across chat, code, thinking, and vision categories using familiar tools. The platform supports streaming, function calling, vision, thinking models, tool use, and multi language workloads, all backed by a pay-per-use credit system billed in USD.

Among the 33 active models available today is Gemma 4 31B (gemma4:31b), a chat-category model that fits general conversational AI, coding assistance, and multilingual content generation. Because Resayil supports both the OpenAI SDK and the Anthropic SDK, you can integrate gemma4:31b into a Python pipeline, a JavaScript microservice, or a no-code n8n workflow without learning a new request format. Integrations also extend to LangChain and LiteLLM for teams building compound AI systems.

This guide walks developers through the entire lifecycle of using Gemma 4 31B on Resayil. You will learn how to verify that the model is live via the /v1/models endpoint, how to send streaming requests through compatible SDKs, and how the pay-per-use billing structure works with Stripe and PayPal.

Unified API Access vs Managing Multiple Providers

When you need to run models like Gemma 4 31B alongside other specialized LLMs, managing direct provider relationships becomes expensive in engineering time. LLM Resayil Portal consolidates access so you can keep a single integration layer.

| Capability | LLM Resayil Portal | Direct OpenAI API | |---|---|---| | API Compatibility | OpenAI and Anthropic compatible | OpenAI format only | | Model Catalog | 33 active models | OpenAI model family only | | Arabic & Multilingual | Arabic language support and multi language | General multilingual capabilities | | Hosting Location | USA | USA | | Billing Currency | USD | USD | | Payment Methods | Stripe, PayPal | Proprietary invoicing and cards | | Pricing Model | Pay-per-use credits | Tiered usage and subscription plans | | SDK & Integration Support | OpenAI SDK, Anthropic SDK, Python, JavaScript, cURL, LangChain, LiteLLM, n8n | OpenAI SDK, Python, JavaScript, cURL | | Streaming | Supported | Supported | | Function Calling | Supported | Supported | | Vision | Supported | Available on select GPT models | | Thinking Models | Supported | Available via o1 series | | Tool Use | Supported | Supported |

LLM Resayil Portal offers a unified interface where features like streaming, function calling, vision, thinking models, and tool use are available across the catalog. Because the platform is OpenAI compatible and Anthropic compatible, you can switch between gemma4:31b and other models without rewriting client logic. The Arabic language support and broader multi language features make the portal especially valuable for builders serving MENA markets or mixed-language user bases. Everything runs on infrastructure hosted in the USA, with billing handled in USD through trusted payment providers.

By contrast, working directly with the OpenAI API limits you to OpenAI’s own model ecosystem. While you gain first-party access to GPT variants and native feature rollouts, you must maintain separate integrations for Anthropic models or other providers. Billing is typically managed through OpenAI’s native dashboard, and you do not receive Anthropic SDK compatibility from the same endpoint.

For developers building multilingual applications that need unified API access to multiple LLM providers, LLM Resayil wins by eliminating integration sprawl. You get one key, one base URL, and immediate access to 33 active models including Gemma 4 31B. Concrete benefits include pay-per-use credits instead of rigid subscriptions, compatibility with both OpenAI and Anthropic SDKs, and support for workflows built in LangChain, LiteLLM, or n8n.

Below is a minimal Python example using the OpenAI SDK and the verified catalog slug:

from openai import OpenAI
import os

client = OpenAI(
    base_url="https://llm.resayil.io/v1",
    api_key=os.environ.get("RESAYIL_API_KEY")
)

response = client.chat.completions.create(
    model="gemma4:31b",
    messages=[{"role": "user", "content": "Explain function calling in Arabic."}],
    stream=True
)

for chunk in response:
    print(chunk.choices[0].delta.content or "", end="")

Verifying Model Availability via the Resayil API

Before you deploy a production prompt, confirm that gemma4:31b is present in the current catalog. LLM Resayil Portal exposes the /v1/models endpoint for exactly this purpose. Calling it returns the list of 33 active models, allowing you to verify slugs and availability without guessing.

A simple verification using cURL looks like this:

curl -s https://llm.resayil.io/v1/models \
  -H "Authorization: Bearer $RESAYIL_API_KEY"

After executing the request, inspect the returned array for an entry with the slug gemma4:31b. Because the API is OpenAI compatible, the payload structure follows conventions familiar from the OpenAI ecosystem, making parsing straightforward in Python or JavaScript.

For a targeted check, query the model-specific endpoint. The portal supports both /v1/models/{id} and /v1/models/{modelId}, so retrieving details for Gemma 4 31B is as direct as:

curl -s https://llm.resayil.io/v1/models/gemma4:31b \
  -H "Authorization: Bearer $RESAYIL_API_KEY"

Automating this step inside your CI/CD pipeline prevents deployment errors when models are rotated or updated. If your application depends on the chat capabilities of Gemma 4 31B, a pre-deployment health check against /v1/health followed by a catalog inspection against /v1/models ensures the environment is ready. You can cache the catalog response for a few minutes to avoid redundant calls, then validate user-selected model strings against the cached list. This pattern is particularly useful when you expose multiple model choices in a UI and need to confirm that the requested slug exists among the 33 active models before spending tokens.

Because the portal maintains Anthropic compatibility alongside OpenAI compatibility, the same verification logic works regardless of which SDK you adopt. Developers using LangChain or LiteLLM can point their model registry to https://llm.resayil.io/v1/models and dynamically load available slugs such as gemma4:31b, mistral-large-3:675b, or gemini-3-flash-preview without hard-coding provider-specific URLs.

Integration with Compatible SDKs

Once you confirm that gemma4:31b is available, the next step is issuing requests. LLM Resayil Portal supports the OpenAI SDK, Anthropic SDK, Python, JavaScript, and cURL, so you can integrate Gemma 4 31B using the stack you already know.

OpenAI SDK (Python)

The OpenAI SDK is the fastest way to start. Set the base_url to https://llm.resayil.io/v1 and pass your Resayil API key.

from openai import OpenAI
import os

client = OpenAI(
    base_url="https://llm.resayil.io/v1",
    api_key=os.environ.get("RESAYIL_API_KEY")
)

completion = client.chat.completions.create(
    model="gemma4:31b",
    messages=[
        {"role": "system", "content": "You are a helpful coding assistant."},
        {"role": "user", "content": "Write a Python function that reverses a string."}
    ],
    stream=True
)

for chunk in completion:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Notice that model is set to the catalog slug gemma4:31b. The stream=True parameter enables real-time token delivery, which is supported by the platform’s streaming feature.

Anthropic SDK (JavaScript)

If your codebase already uses the Anthropic SDK, you can redirect it to Resayil’s Anthropic-compatible endpoint. The following example sends a message request to gemma4:31b:

import Anthropic from '@anthropic-ai/sdk';

const client = new Anthropic({
  baseURL: 'https://llm.resayil.io/v1',
  apiKey: process.env.RESAYIL_API_KEY,
});

const message = await client.messages.create({
  model: 'gemma4:31b',
  max_tokens: 1024,
  messages: [{ role: 'user', content: 'What are the best practices for multilingual API design?' }],
});

console.log(message.content);

Because the portal is Anthropic compatible, the SDK handshake, message counting via /v1/messages/count_tokens, and message creation via /v1/messages all work against the same base URL.

cURL and JavaScript Fetch

For lightweight scripts or edge functions, raw HTTP requests work identically:

curl https://llm.resayil.io/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $RESAYIL_API_KEY" \
  -d '{
    "model": "gemma4:31b",
    "messages": [{"role": "user", "content": "مرحباً"}],
    "stream": true
  }'

In browser or Node.js environments using JavaScript:

const res = await fetch("https://llm.resayil.io/v1/chat/completions", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": `Bearer ${process.env.RESAYIL_API_KEY}`
  },
  body: JSON.stringify({
    model: "gemma4:31b",
    messages: [{ role: "user", content: "Explain pay-per-use billing." }],
    stream: true
  })
});

Advanced Features

The platform’s verified features include function calling, tool use, and support for thinking models. When using gemma4:31b, you can attach tool definitions to the tools array in your chat completion payload. Vision is also a platform feature; while gemma4:31b is categorized as a chat model, the same API structure lets you call vision-capable models like glm-5.1 without changing integration patterns.

For workflow automation, the portal integrates with n8n. For orchestration in Python applications, both LangChain and LiteLLM can use https://llm.resayil.io/v1 as a provider URL, passing gemma4:31b as the model name. This flexibility means you are never locked into a single SDK to access the 33-model catalog.

Pricing and Billing Structure

LLM Resayil Portal uses a pay-per-use credit system. Every request to gemma4:31b consumes credits based on token usage, and you add funds only when needed. All billing and topups are conducted in USD, keeping currency conversion simple for global teams.

You can review current rates programmatically through the /v1/pricing endpoint:

curl -s https://llm.resayil.io/v1/pricing \
  -H "Authorization: Bearer $RESAYIL_API_KEY"

When your balance runs low, the /v1/pricing/topups endpoint provides a programmatic path to add credits. For manual management, the dashboard accepts payments via Stripe and PayPal, the two verified payment methods supported by the platform.

This model replaces rigid monthly subscriptions with granular control. Developers prototyping with gemma4:31b can start with a small top-up, scale usage as user traffic grows, and never pay for idle capacity. Because the entire catalog of 33 active models shares the same credit pool, you can A/B test gemma4:31b against mistral-large-3:675b or ministral-3:14b without managing separate provider bills.

Hosting in the USA ensures consistent latency for North American and global users, while the unified USD pricing eliminates the complexity of multi-currency accounting. Whether you are building chatbots, code assistants, or multilingual content pipelines, the pay-per-use structure aligns costs directly with production traffic.
