Why Choose Nexevo.ai

Teams who want to use flagship AI but don’t want to pay flagship bills are here.

Truly smart routing

Each question is judged by intent—reasoning, programming, chat, visual, long context—and routed to a specialist model. You get flagship answers without paying flagship prices.

100+ models, one conversation

OpenAI, Anthropic, Google, DeepSeek, Mistral, xAI, Tongyi, Moonshot, etc.—unified and packaged under one API and one brand. When we plug in the next great model, your code doesn't need to change.

Save up to 56% on costs

Smart routing selects the model that is “good enough and cheapest”. Semantic caching reduces duplicate issues by 25%. We bear the cost of retrying, and users only pay for the final answer they see.

Extremely fast and efficient, zero learning cost

Two-level caching reduces common problems to millisecond responses. Parallel hedging paths are only enabled when really needed. There is no need to learn model selection or fine-tuning prompts—just ask.

Quality gated automatic rollback

If the first answer score falls below the threshold, we try again with a stronger model at our own expense - you only pay for the final answer delivered.

Enterprise-grade security

TLS 1.3, per-key rate limiting + IP whitelist, long-term storage of PII desensitization, hash chain audit logs, SOC 2 is on the roadmap.

quick start

Compatible with OpenAI SDK - just change one line base_url.

# pip install openai
from openai import OpenAI

client = OpenAI(
    base_url="https://api.nexevo.ai/v1",
    api_key="sk-your-nexevo-key",
)

response = client.chat.completions.create(
    model="nexevo/balanced",                   # we pick the best model for each request
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

FAQ

What models does the platform cover?+

100+ models, including OpenAI (GPT-4o), Anthropic (Claude 3.5), Google (Gemini 2.0), DeepSeek, Mistral, xAI, Qwen, etc. Flat billing: Input $3 / Output $12 per million tokens - Intelligent routing will pick the cheapest model that meets quality.

How does intelligent routing work?+

Each request is first classified by intent (reasoning, programming, chat, visual, long context) and then routed to the corresponding specialized model. When the quality is not up to standard, we retry with a stronger model at our own expense, and you only pay for the final answer.

Can my OpenAI code be used directly?+

Yes. We are compatible with OpenAI SDK - change `base_url` to `https://api.nexevo.ai/v1`, replace it with your Nexevo API Key, and leave other codes unchanged.

Will my data be used for training?+

No. Requests are forwarded to the upstream provider to the extent you agree and we do not retain the data for training purposes. See privacy policy for details.
