Will it fit? Say what model you want — localfit figures out the rest.

Fits locally? Run it via MLX or llama.cpp. Doesn't fit? Kaggle free GPU. Still too big? RunPod cloud. Need a custom quant? Quantize remotely and upload to HuggingFace. You never think about hardware.

pip install localfit

Quick Start

localfit                              # GPU dashboard + trending models
localfit run gemma4:e4b               # interactive menu: pick MLX, GGUF, or Cloud
localfit run qwen3:14b                # doesn't fit? menu shows Kaggle/RunPod options
localfit --launch claude              # start model + launch Claude Code
localfit makeitfit llama-4-scout      # quantize remotely → upload to your HuggingFace

The Run Menu

When you localfit run MODEL, you get an interactive menu with arrow key navigation — pick your backend before anything downloads:

• MLX — Native Apple Silicon, fastest on Mac. Auto-discovers mlx-community models.
• GGUF — llama.cpp with Metal/CUDA. Works everywhere.
• Kaggle — Free 30h/week GPU. One click to deploy.
• RunPod — Paid cloud GPU. Auto-picks cheapest that fits.

Backends

MLX (Apple Silicon)

localfit auto-detects if you have mlx-lm installed and finds MLX models on HuggingFace:

pip install mlx-lm                    # one-time setup
localfit run gemma-3-4b-it            # auto-picks mlx-community/gemma-3-4b-it-8bit

If no mlx-community model exists, localfit can convert any HuggingFace model to MLX locally:

localfit run bytedance-research/UI-TARS-7B-DPO
# → No mlx-community model found
# → "Convert locally? mlx_lm needs ~14GB RAM (you have 24GB)"
# → Converts to MLX 4-bit → serves immediately

GGUF (llama.cpp)

The default for all platforms. localfit downloads the best GGUF quant for your GPU and serves via llama-server:

localfit run gemma4:26b               # MoE, 12GB, best quality on 24GB Mac
localfit show gemma4:26b              # show all quants + fit analysis + cloud pricing

Remote Kaggle (Free)

30 hours/week of free T4 GPU. localfit auto-deploys via Cloudflare tunnel:

localfit run qwen3:14b --remote kaggle
localfit --remote-status              # check active session
localfit --remote-stop                # stop + free quota

Remote RunPod (Paid)

Any GPU size. Live pricing from the API. Auto-stop when budget runs out:

localfit login runpod                 # save API key
localfit run gemma4:27b --cloud       # auto-provision + tunnel
localfit --stop                       # kill pod + stop billing

Make It Fit — Remote Quantization

Can't find the right quant? Create your own and upload to HuggingFace:

localfit makeitfit Qwen2.5-7B-Instruct

  Your GPU: Apple Silicon 16GB
  Model: Qwen/Qwen2.5-7B-Instruct (14GB BF16)

  1  Quantize on Kaggle (free) → Q4_K_M GGUF     ~7 min
  2  Quantize on RunPod         → Q5_K_M GGUF     ~$0.10
  3  Serve remotely (no quant)

  Pick option:

How it works:

1. Picks Kaggle GPU (free) or RunPod (cheapest available)
2. Downloads model from HuggingFace
3. Converts to F16 GGUF via llama.cpp
4. Quantizes to your chosen method (Q4_K_M, Q5_K_M, Q8_0, etc.)
5. Uploads to your HuggingFace repo
6. Run it: localfit run yourname/model-Q4_K_M-GGUF-localfit

Uses llama.cpp native tools — no Unsloth dependency, works reliably on Kaggle and RunPod.

Launch Any Tool

Start a model and launch your coding tool in one command:

localfit --launch claude              # Claude Code
localfit --launch claude --model gemma4:26b
localfit --launch codex               # OpenAI Codex CLI
localfit --launch opencode            # OpenCode
localfit --launch aider               # aider
localfit --launch webui               # Open WebUI (ChatGPT-style browser)
localfit --launch webui --tunnel      # + public URL via Cloudflare

Works with both local and remote models. Env vars are scoped to the subprocess only — your normal tool setup is never touched.
