If you are using the OpenAI API directly, Vynex gives you the same OpenAI-compatible interface — plus every other frontier model family behind the same single key. No SDK rewrite, no new client library.
It is the simplest way to add Claude, Gemini, DeepSeek and open models to an app that already speaks OpenAI.
| Feature | Vynex API | direct OpenAI |
|---|---|---|
| OpenAI-compatible /v1 endpoint | ✓ | ✓ |
| Call GPT-5.x models | ✓ | ✓ |
| Call Claude from the same key | ✓ | ✗ |
| Call Gemini from the same key | ✓ | ✗ |
| Streaming + tool calling | ✓ | ✓ |
| Works where OpenAI is region-blocked | ✓ | ✗ |
| Per-token pricing, no lock-in | ✓ | ✓ |
| Switch model with one parameter | ✓ | Only OpenAI models |
from openai import OpenAI
client = OpenAI(
api_key="sk-...",
base_url="https://llm-api.vynexcloud.com/v1",
)
# Now this works for GPT, Claude, Gemini, etc:
client.chat.completions.create(model="claude-sonnet-4-6", messages=[...])Yes for chat, streaming, and tool calling. You keep the official OpenAI SDK and only change base_url and api_key. The /v1/chat/completions contract is preserved.
The GPT family including GPT-5.x variants. The exact list is on the /pricing page and updates as OpenAI releases new models.
One key and one base_url for every frontier model, transparent per-token pricing, and access from regions where direct OpenAI is restricted.
