What this repo contains

config.json (max profile), modeling_faber_genesis.py (self-contained HF model code), genesis_profiles.json, tokenizer_config.json (placeholder config, vocab 32768 — train a real tokenizer before pretraining), benchmark_genesis_a100.py, EVIDENCE_GENESIS_A100_MAX.md.

No trained weights are included in this upload. config.json defines a random-init architecture. To materialize weights:

from modeling_faber_genesis import FaberGenesisConfig, FaberGenesisForCausalLM
cfg = FaberGenesisConfig()  # max-13.86B
model = FaberGenesisForCausalLM(cfg)  # random init, BF16 training recipe applies on A100

Ceiling benchmark (run on A100 80GB)

pip install "torch==2.6.0" bitsandbytes transformers
python benchmark_genesis_a100.py --profile max-13.86B --steps 1
python benchmark_genesis_a100.py --sweep --n-list 25,29,32,33,34,35,36,37 --steps 1

Pass = fwd+bwd+optim step completes; n=36/37 must OOM. VRAM estimates in EVIDENCE_GENESIS_A100_MAX.md are analytic, not a substitute for this run.

Limitations

Random-init step-pass says nothing about Thai/code/reasoning quality. Quality requires pretraining curriculum + CASS + verifier + agent training and SWE/APEX evals. 14.25B+ is not a single-A100 resident AdamW8bit config.
