DeepInfra raises $107M Series B to scale the inference cloud — read the announcement

DeepInfra is officially live as an Inference Provider on the Hugging Face Hub. You can now call DeepInfra-hosted models directly from Hugging Face model pages, through our OpenAI-compatible router (use it with any OpenAI SDK), or via the Hugging Face SDKs in Python and JavaScript.
Hugging Face's Inference Providers system lets developers run inference against partner platforms without leaving the Hub. As of today, DeepInfra is one of those partners.
At launch, we support chat completion and text generation tasks. That covers most open-weight LLMs people deploy in production — DeepSeek V4, Kimi-K2.6, GLM-5.1, Llama, Qwen, Mistral, and many more. Support for our other model categories (text-to-image, text-to-video, embeddings, speech) will roll out next.
You can browse every DeepInfra-supported model here: 👉 huggingface.co/models?inference_provider=deepinfra
You have two ways to authenticate, and both work with the same code.
Option 1 — Use your DeepInfra API key. Add it to your Hugging Face provider settings. Requests go directly to DeepInfra and are billed to your DeepInfra account at standard rates.
Option 2 — Use your Hugging Face token. Hugging Face will route your request to DeepInfra and bill it to your HF account. PRO users get $2 of inference credits each month; free users get a small monthly quota.
from huggingface_hub import InferenceClient
client = InferenceClient()
completion = client.chat.completions.create(
model="deepseek-ai/DeepSeek-V4-Pro:deepinfra",
messages=[
{"role": "user", "content": "Write a Fibonacci function with memoization."}
],
)
print(completion.choices[0].message)
import { InferenceClient } from "@huggingface/inference";
const client = new InferenceClient(process.env.HF_TOKEN);
const completion = await client.chatCompletion({
model: "deepseek-ai/DeepSeek-V4-Pro:deepinfra",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message);
The Hugging Face router is OpenAI-compatible, so existing OpenAI code works with one line changed — point base_url at the HF router:
from openai import OpenAI
client = OpenAI(
base_url="https://router.huggingface.co/v1",
api_key=os.environ["HF_TOKEN"],
)
completion = client.chat.completions.create(
model="deepseek-ai/DeepSeek-V4-Pro:deepinfra",
messages=[{"role": "user", "content": "Hello!"}],
)
The only thing that changes is the :deepinfra suffix on the model id.
If you already use DeepInfra, nothing changes — your existing API and account work exactly as they always have. What's new is reach.
DeepSeek V4 Flash vs Qwen3.6 vs GLM-4.6 Benchmarks<p>A breakdown of three open-weight models across intelligence, speed, and inference cost. Three open-weight models cover most of what a developer needs from open inference right now: DeepSeek V4 Flash, Qwen3.6 35B A3B, and GLM-4.6. All three run on DeepInfra, and all three use a Mixture-of-Experts design that keeps active parameters low while total capacity […]</p>
Qwen3.5 2B via DeepInfra: Latency, Throughput & Cost<p>About Qwen3.5 2B (Reasoning) Qwen3.5 2B is a compact 2-billion parameter open-weights model released in March 2026 as part of Alibaba Cloud’s Qwen3.5 Small Model Series. It employs an Efficient Hybrid Architecture combining Gated Delta Networks (a form of linear attention) with sparse Mixture-of-Experts, delivering high-throughput inference with minimal latency overhead — a significant architectural […]</p>
Best Kimi K2.6 API Providers for Developers (2026)<p>Kimi K2.6 is available across a range of hosted API providers, and the right choice depends on what your workload optimizes for — latency, throughput, cost, deployment flexibility, or native feature support. This guide covers the top options by use case. For a detailed cost breakdown across workload types, see the Kimi K2.6 pricing guide. […]</p>
