gguf version incase anyone wants it :) sadly the model is too small for a q8 or under gguf :( so only fp32, fp16, and bf16 are avaliable for gguf

AppleMind-1.0-Mini

AppleMind-1.0-Mini is a compact decoder-only causal language model trained from scratch by AppleMind on a 300M-token curriculum.

The model has 1,020,480 parameters, a 256-token context window, and a 50,263-token digit-aware byte-level BPE tokenizer (GPT-2 + special tokens).

Tokenizer

AppleMind 1.0 Mini uses a 50,263-token digit-aware byte-level BPE tokenizer based on the GPT-2 tokenizer, with 3 additional special tokens. Digits are handled individually rather than being collapsed into large number tokens.

Special token	ID
`<\|pad\|>`	50,260
`<\|bos\|>`	50,261
`<\|eos\|>`	50,262

Training Data

Dataset	Target Tokens	Share
FineWeb-Edu	100M	33.33%
FineWeb-HQ	100M	33.33%
SmolLM-Corpus	100M	33.33%
Total	300M	100%

The training run used an equal mixture of FineWeb-Edu, FineWeb-HQ, and SmolLM-Corpus, with 100M tokens sampled from each dataset.

Usage

AppleMind 1.0 Mini uses custom architecture code, so load it with trust_remote_code=True.

pip install -U transformers safetensors torch

python

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "AppleMind-AI/AppleMind-1.0-Mini"

tokenizer = AutoTokenizer.from_pretrained(
    model_id,
    trust_remote_code=True,
)

device = "cuda" if torch.cuda.is_available() else "cpu"

dtype = (
    torch.bfloat16
    if torch.cuda.is_available() and torch.cuda.is_bf16_supported()
    else torch.float32
)

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    trust_remote_code=True,
    torch_dtype=dtype,
).to(device).eval()

prompt = "The color of the sky is"

inputs = tokenizer(
    prompt,
    return_tensors="pt",
).to(device)

with torch.no_grad():
    output = model.generate(
        **inputs,
        max_new_tokens=96,
        do_sample=True,
        temperature=0.7,
        top_p=0.9,
        repetition_penalty=1.1,
        pad_token_id=tokenizer.eos_token_id,
        eos_token_id=tokenizer.eos_token_id,
    )

print(
    tokenizer.decode(
        output[0],
        skip_special_tokens=True,
    )
)

Note: AppleMind 1.0 Mini has a 256-token context window, so the prompt plus generated tokens should stay within that limit.
