Portix — One Gateway. Every Model.

Model gateway routes, protocol conversion, managed WebSearch, and agent-ready integrations for production AI systems.

Portix is a platform that gives developers access to hundreds of large language models through a single API. Instead of maintaining separate integrations for OpenAI, Anthropic, Mistral, Google, and dozens of other AI companies, and juggling between them, we connect to one endpoint, authenticate once, and get access to more than 400 models.

Platform Surfaces

Gateway API

Use one gateway layer for provider routing, protocol compatibility, and model access.

Managed Tools

Add WebSearch and retrieval surfaces that work well inside agent workflows.

Agent Integrations

Connect Claude Code, OpenClaw, OpenCode, and LangChain to portix.

The Problem

Every AI provider has its own SDK, API format, and authentication method. Switching between OpenAI, Anthropic, and Gemini means rewriting integration code, managing multiple API keys, and risking vendor lock-in.

Gateway Compatibility

Portix provides native protocol conversion at the gateway level. Your existing code works as-is — just change the base URL.

Use OpenAI SDK

Call Claude, Gemini, DeepSeek, Llama and more — all through the OpenAI SDK you already know.

Use Anthropic SDK

Call GPT, Gemini, Grok, DeepSeek and more — all through the Anthropic SDK you already know.

Use Gemini SDK

Call GPT, Claude, DeepSeek and more — all through the Gemini SDK you already know.

OpenAI SDK → Claude
Anthropic SDK → Gemini
Gemini SDK → GPT

# Call Claude using OpenAI SDK
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.portix.ai/openai/v1"  # ← just change this
)

response = client.chat.completions.create(
    model="claude-sonnet-5",  # ← use any model
    messages=[{"role": "user", "content": "Hello!"}]
)

# Call Gemini using Anthropic SDK
import anthropic

client = anthropic.Anthropic(
    api_key="YOUR_API_KEY",
    base_url="https://api.portix.ai/anthropic"  # ← just change this
)

message = client.messages.create(
    model="gemini-3.6-flash",  # ← use any model
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)

# Call GPT using Gemini SDK
from google import genai

client = genai.Client(
    api_key="YOUR_API_KEY",
    http_options={"base_url": "https://api.portix.ai/gemini"}  # ← just change this
)

response = client.models.generate_content(
    model="gpt-5.5",  # ← use any model
    contents="Hello!"
)

Who Is Portix For

Startups & Dev Teams

Evaluate and switch models in minutes, not weeks. Test GPT, Claude, Gemini, DeepSeek side-by-side with your existing codebase. No SDK migrations, no new auth flows — just swap the model name.

Enterprises

Add latest AI capabilities to legacy systems without rewriting code. Your production integrations built on OpenAI SDK can instantly access Claude or Gemini. Zero migration cost, full protocol compatibility.
