Local-first least cost routing system to reduce 80%+ token spend

Conifer is one app that connects you to every AI model (local and cloud) and automatically routes each request to the cheapest model that accomplishes your goal. Most requests run free on your own hardware, so teams cut their AI bill by ~80% while replacing a dozen provider contracts with one interface and one invoice. For sensitive material like financials or user data, a secure mode pins everything on-device with no external API calls.

Conifer: Local-first least cost routing system
See original launch post

Hi all 👋, We’re Michael and Charles, founders of Conifer.

TLDR: Conifer is one interface for both local and cloud models, available today as Juniper, our consumer-facing app. It routes each request to the most cost-effective option, beginning with your own hardware. Most requests are processed locally without API fees, reducing paid token volume by up to 80%.

❓ The problem: Model labs direct every request to the cloud, with no incentive to route your queries to a cheaper competitor or a free, on-device model. That may benefit them, but it’s unnecessarily costly for you. Whether it’s a simple typo fix or a complex architecture problem, the request is sent to a data center, exposing your data to third parties and increasing your monthly spend. This quickly adds up for teams running coding agents, customer support, and other high-volume workloads. When handling financials, patient records, or customer data, teams must also trust that a cloud provider’s security is as robust as promised.

🔨 What Conifer does: Conifer routes every request from the bottom up:

Tier 0: Your own hardware, with $0 in API fees

Tier 1: An efficient cloud model

Tier 2: A frontier model for the most demanding queries

The majority of requests are processed locally, ensuring that cloud pricing applies only when actually necessary, drastically reducing paid token volume. Additionally, Conifer consolidates disparate subscriptions, dashboards, and API keys within a single unified interface.

For sensitive workloads 🕵️, local-only mode disables cloud routing entirely, so all conversations and data remain completely on-device.

🏃‍♂️ Ensuring the local tier is fast enough: This routing only works if the local tier is reliable, so we built Conifer's inference engine from the ground up in Rust. On Apple Silicon, decode speeds reach up to 60% faster than llama.cpp.

On-device operation with Conifer is now the default starting point for inference, rather than a feature limited to hobbyist use.

Asks:

  1. Try Juniper with a one-click download @ conifer.build, or reach out to us at contact@conifer.build to have a model running in under two minutes.
  2. Introduce us to teams with high monthly token spend. If teams are incurring significant API costs and want to optimize unit economics without rebuilding their stack, we would like to connect.
