Ember

Developer API

A single, resilient API for all frontier models.

Ember dashboard illustration

Model APIs fail, change, and latency spikes. Ember provides a unified, highly optimized gateway that handles caching, cost controls, and fallback routing automatically.

The Friction

The Problem

Directly integrating multiple LLM providers leads to messy API wrappers, high API costs from duplicate prompts, and unpredictable downtime when providers go offline.

The Intervention

The Solution

Ember is a lightweight proxy that unifies access to OpenAI, Anthropic, Gemini, and local models. It features semantic prompt caching, cost limits, auto-fallback, and real-time observability logs.

Behind the Scenes

Story of the Craft

We built Ember to insulate Meros products from API failures. When one LLM provider had an outage, our products automatically switched to a backup model without the users noticing. We realized this routing layer is essential infrastructure for any AI engineering team.

Functional Details

Core Capabilities

Feature 01

Semantic Caching

Saves up to 60% on token costs by matching semantically similar prompts and returning cached responses.

Feature 02

Smart Fallbacks

Detects rate limits and server errors, instantly rerouting traffic to fallback models within milliseconds.

Feature 03

Token Rate Limits

Allows developers to configure custom spend caps per user, project, or API key in real-time.

Engineering Stack

Technical Architecture

High-performance Rust-inspired Go or TypeScript proxy deployed on Vercel Edge. Utilizes Redis Cluster for caching and real-time token bucket rate limiting.
