The open-source AI community is evolving rapidly, and hardware efficiency is becoming as critical as model performance. For our next open-source project, we’re considering two key options:

  1. An O3-Mini level model

    – A relatively small model that still requires GPUs for efficient inference.

  2. A phone-sized model

    – The most optimized model possible that can run effectively on consumer mobile hardware.

Both approaches have distinct advantages, but which one would be more useful to the community? Let’s break it down.

Option 1: O3-Mini Level Model – Small, But GPU-Dependent

What It Offers:

  • Higher Performance

    : This model would provide more power than a typical phone-sized AI, making it ideal for

    more complex reasoning, longer contexts, and better response quality

    .

  • Accessible for Local AI Users

    : Many developers and companies prefer small, yet powerful models they can fine-tune and run efficiently on

    consumer GPUs

    (e.g., RTX 4090, A100).

  • Strong for Edge AI & On-Prem Solutions

    : Enterprises looking to deploy AI

    without cloud dependency

    can benefit from this model.

Challenges:

  • Still Requires GPUs

    : While it’s smaller than GPT-4 class models, it won't run on mobile or edge devices as efficiently as a true lightweight model.

  • Hardware Costs

    : While more accessible than large-scale LLMs, it still demands a GPU setup, limiting accessibility for some users.

Who Would Benefit?

  • AI developers building

    on-prem

    AI assistants.

  • Researchers fine-tuning models for

    edge deployments

    .

  • Companies looking to host

    lightweight private AI systems

    .

Option 2: The Best Phone-Sized Model – Ultra Lightweight AI

What It Offers:

  • Runs on Mobile & Edge Devices

    : A

    truly portable AI

    , accessible without a GPU, making it ideal for

    real-time applications

    like personal assistants, chatbots, and IoT.

  • Massive Reach

    : More people globally can experiment with AI

    without cloud costs

    .

  • Low Power Consumption

    : Ideal for

    on-device AI

    use cases, from

    AI-powered keyboards

    to

    offline translation models

    .

Challenges:

  • Limited Reasoning Ability

    : Due to size constraints, it may struggle with

    long-form text generation, complex problem-solving, and deep contextual memory

    .

  • Trade-Offs in Accuracy

    : The smaller the model, the more challenging it is to maintain performance parity with larger LLMs.

Who Would Benefit?

  • Mobile developers integrating AI into

    apps, chatbots, and assistants

    .

  • Edge computing applications needing

    fast, lightweight AI processing

    .

  • Users who want

    AI without cloud reliance

    .

Which One Should We Build?

The decision depends on the use case priorities of the AI community.

🔹 If the goal is accessibility, a phone-sized model is the clear winner—it enables AI for millions of users, even on budget smartphones.

🔹 If the goal is a balance of power and efficiency, an O3-Mini level model makes more sense—it’s small enough for easy deployment yet powerful enough to handle complex AI tasks.

What Do You Think?

We’re open to community feedback—what would be more impactful for the AI ecosystem? A small but powerful GPU-based model, or the best mobile-friendly AI possible?
