Libraries

How to use kuluruvineeth/manas-64m-pretrain with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="kuluruvineeth/manas-64m-pretrain")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("kuluruvineeth/manas-64m-pretrain")
model = AutoModelForCausalLM.from_pretrained("kuluruvineeth/manas-64m-pretrain", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)

Manas-64M · Pretraining

The base model: 63.9M parameters trained from random weights on about 1.5B tokens of English web, textbook and story text. Every other Manas stage starts here.

Try it: chat Space · Every stage: collection · Code: github.com/kuluruvineeth/manas · Data: manas_dataset

Results

	value
held-out loss	2.145
training loss, first → last log point	5.552 → 2.074
training steps	92,814
tokens processed	≈1.52B (throughput × time)
wall-clock	175 min at ~145k tokens/s

Benchmarks

Zero-shot multiple choice, 500 items per task, scored by comparing answer log-likelihoods (scripts/evaluate.py).

benchmark	accuracy	random chance	items
arc_challenge	21.8%	25.1%	500
arc_easy	31.8%	25.0%	500
hellaswag	35.4%	25.0%	500
mmlu	25.0%	25.0%	500
openbookqa	28.8%	25.0%	500
average	28.6%

A 64M model has far less capacity than these benchmarks assume, so scores sit near random chance. They are published because hiding them would be dishonest, and they move by about a point between stages, which is within noise at 500 items.

Use

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "kuluruvineeth/manas-64m-pretrain"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForCausalLM.from_pretrained(repo)

messages = [{"role": "user", "content": "What is the capital of France?"}]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt", return_dict=True)
out = model.generate(**inputs, max_new_tokens=60, do_sample=False)
print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))

The export is a standard transformers checkpoint, so vLLM and SGLang load it with no custom code (vllm serve kuluruvineeth/manas-64m-pretrain).

Training

Lineage: starts from random weights.
Method: next-token prediction, sequence length 512, batch 32 with 8 accumulation steps, cosine decay to 10% of the peak learning rate.
Data: pretrain_t2t.jsonl: FineWeb-Edu sample-10BT, Cosmopedia v2, TinyStories (sources and licenses).
Trainer: trainer/train_pretrain.py, peak learning rate 5e-4 (from the training log).
Hardware: one A100 or H100 GPU on Modal (gpu/modal_train.py).
Architecture: Qwen3 layout: 768 hidden, 8 layers, 8 query / 4 key-value heads (head dim 96), SwiGLU MLP of width 2,432, RoPE θ = 10⁶, tied embeddings, 6,400-token byte-level BPE vocabulary. 63,912,192 parameters.

Limitations

English only. At this size the model has little world knowledge: it is confidently wrong about facts that need it, loses the thread in long conversations, and should not be used for anything that matters. It is a teaching and research artifact for studying how each training stage changes a model.
