Narev

Narev is a platform for optimizing Gen AI apps

Faster, cheaper, better.

Build your own router.

Route simple queries to fast models, complex ones to advanced models. Same quality, lower cost, lower latency.

Forget the benchmarks. Skip the evals. A/B test instead.

Use A/B testing to find the optimal models, prompts, and parameters in production. Get real data on what works best for your use case.

Support for every modality

Text, audio, image, and video - we handle it all

Text

Build faster code agents by routing between GPT-4 for complex logic and Claude for quick refactors.

Audio

Reduce latency for real-time transcription. Route to Deepgram for speed, Whisper for accuracy.

Image

Get the best image output immediately. Test DALL-E, Midjourney, and Stable Diffusion in parallel.

Video

Compare all video providers side-by-side. Find which model delivers the quality you need, faster.

And... provider choice can make or break your latency

Same model, same code, but 50% faster latency just by switching providers. Your AI decisions shouldn't be a gamble.

AI budgets are bleeding money on the wrong tradeoffs

That $5 model with 15-second latency costs you more in lost conversions than the $20 fast model. Optimize for total business impact, not just price per token.
