I was tired of paying for 5 separate AI subscriptions, so I spent 2 months building Fius — a unified AI model aggregator startup

Hi everyone,

We are the team behind Fius (https://fius.dev), an early-stage developer productivity startup. We built this platform because managing subscription fragmentation and API chaos was completely ruining development velocity.

As software engineers, we found ourselves trapped in an inefficient workflow: constantly switching web tabs, copy-pasting complex prompts, and juggling individual API keys for OpenAI, DeepSeek, and other providers just to get the best coding results.

Fius resolves this friction. We consolidate access to an expansive roster of flagship AI models into a single, unified developer token and a centralized billing system. This allows engineering teams to route queries to the best-suited model instantly without infrastructure overhead.

Here is a breakdown of our production-ready stack and features:

Infrastructure & Scaling
Our complete web console infrastructure is fully operational and hosted on Microsoft Azure cloud enterprise architecture, supported by official startup grants.
Global Billing Integration
We have deployed a fully active international merchant billing engine via PayPro Global. The tokenomics are straightforward: 100 platform credits equal 1 USD.
Advanced Developer Toolkit
A high-performance, cross-platform Terminal CLI assistant workspace. It features native, low-latency autocomplete and advanced multi-file code refactoring workflows directly inside your terminal.

Our Multi-Model Catalog (Examples):

gpt-5.4-nano: A lightweight, ultra-fast micro-model optimized for instant terminal command auto-completion at near-zero credit cost.
DeepSeek-V4-Pro & grok-4-1-fast-reasoning: Advanced reasoning workhorses designed for complex software architecture, deep debugging, and multi-file code generation.
Specialized Alternatives: Models like Kimi-K2.6, mistral-medium-3-5, and many others tailored for flexible, cost-effective routing.

We support a much wider and constantly expanding range of models. You can explore the full up-to-date catalog and integration details in our official documentation on the website.

As we scale our startup, we want to ensure Fius meets the rigorous demands of production workflows. We would highly appreciate your brutal feedback on our terminal CLI, infrastructure architecture, or any specific models you would like to see us deploy next.
