ScrapeGoat Architecture


🌟 Overview

ScrapeGoat is a parallel dual-track transformer modeled after the human brain's hemispheric specialization β€” Track A (analytical left brain) for deep sequential reasoning via KDA recurrent attention, Track B (holistic right brain) for broad parallel processing via GQA. Both tracks run simultaneously at every layer, united by learned gating. This architecture is purpose-built for humanoid embodied intelligence, combining the precision needed for logic, motor planning, and sequential reasoning with the flexibility required for natural language, spatial awareness, and multimodal perception. The architecture is derived from ScrapeGoat's Agentic Modelling and ranging innovations from DeepSeek (DSpark) / Kimi K2 (KDA) with custom modifications including KDA (Kimi Delta Attention), Quantile Balancing MoE, and Mixture-of-Memories (MoM).

πŸ—οΈ Architecture

Parallel Dual-Track Processing

Both tracks process every token in parallel at each of the 81 layers, with learned gating per layer for attention (attn_track_gate) and MoE (moe_track_gate):

Layer 0 (Special) Layers 1–80
Track A: MoE only (no attn) Track A: KDA attention + MoE
Track B: Attention + dense FFN (no MoE) Track B: GQA attention + MoE

⚑ KDA (Kimi Delta Attention)

Recurrent linear attention with diagonal gating:

S_t = (I - Ξ²_t k_t k_t^T) Diag(Ξ±_t) S_{t-1} + Ξ²_t k_t v_t^T
  • Supports recurrent (inference) and chunkwise (training) modes
  • ShortConv preprocessing for Q/K/V projections (kernel=3)
  • Interleaved with GQA every 4th layer: kda_gqa_layers = [0,4,8,...,80] (21 GQA layers, 60 KDA layers)

🎯 Quantile Balancing for MoE

  • Hyperparameter-free load balancing via alternating quantile algorithm
  • Computes per-expert biases that equalize token assignment
  • 8 experts selected per token across 512 (Track A) + 192 (Track B) experts

🌊 Mixture-of-Memories (MoM-KDA)

  • Multiple independent KDA memory states with learned routing
  • Shared memory always active + top-2 memory selection per token
  • 4 memories total, 2 active per token

πŸ”„ StableMoE Stage 1

  • Progressive routing stabilization
  • Reduces expert representation collapse during training

Loading for Inference

import sys
sys.path.insert(0, "/path/to/model/dir")
from configuration_scrapegoat import ScrapeGoatConfig
from modeling_scrapegoat import ScrapeGoatForCausalLM
from transformers import AutoTokenizer
import torch

model_dir = "/path/to/scrapegoat-weights"

tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)
model = ScrapeGoatForCausalLM.from_pretrained(
    model_dir,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)

Tokenizer

ScrapeGoat uses the Kimi K2 tiktoken BPE tokenizer (tiktoken.model from the Kimi K2 checkpoint). The vocabulary is 248,320 tokens (163,584 base BPE merges + 256 special/control tokens). The Kimi tokenizer was chosen because:

  • BPE on bytes β€” lossless encoding of any Unicode/UTF-8, no OOV tokens
  • Special token slots β€” 256 reserved slots for [BOS], [EOS], [PAD], [UNK], role markers, tool call tokens, media tokens, etc.
  • Proven at scale β€” battle-tested in Kimi K2's pretraining pipeline
  • tiktoken backend β€” fast Rust implementation, easily swappable with Gigatoken

Special tokens:

Token ID Purpose
[BOS] 163584 Begin of sequence
[EOS] 163585 End of sequence
[PAD] 163839 Padding
[UNK] 163838 Unknown
[EOT] 163593 End of turn
<|im_end|> 163586 Chat message end
<|im_user|> 163587 User role marker
<|im_assistant|> 163588 Assistant role marker
<|im_system|> 163594 System role marker
<|tool_calls_section_begin|> 163595 Tool calls section
<|tool_call_begin|> 163597 Individual tool call
<|media_begin|> 163602 Media/vision content
<think> 163606 Reasoning section begin
</think> 163607 Reasoning section end

Default backend: tiktoken via HuggingFace AutoTokenizer + custom tokenization_kimi.py.

πŸš€ Gigatoken (Recommended)

Gigatoken (v0.10.0, Jul 2026 by Marcel RΓΈd, Stanford) is a Rust BPE tokenizer that loads the same tiktoken.model file. It's a drop-in replacement with 750Γ— faster encoding:

Backend Throughput (Kimi K2 vocab) Relative
HuggingFace Tokenizers ~26 MB/s 1Γ—
tiktoken β€” ~50Γ—
Gigatoken 18.85 GB/s ~750Γ—

The speed comes from three optimizations:

  • SIMD pretokenization β€” replaces the regex engine with hand-written SWAR (Single-Word-Aside Register), no branching in hot loops
  • Aggressive caching β€” repeated words are hash lookups, not full recomputation
  • Zero Python overhead β€” encode_files() streams directly from disk via Rust I/O, parallelized across cores

Usage β€” native API (fastest path, read files directly):

import gigatoken as gt

# Accepts HF model names or local paths
tokenizer = gt.Tokenizer("/path/to/scrapegoat-weights")

# Batched encoding (file-based, no Python loops)
source = gt.TextFileSource(["train.jsonl"], separator=b"[EOS]")
tokens = tokenizer.encode_files(source)

# In-memory encoding
ids = tokenizer.encode("Hello, world!")

Usage β€” HF-compatible API (for SFTTrainer / existing pipelines):

import gigatoken as gt
tokenizer = gt.Tokenizer("/path/to/model").as_hf()
# Now usable anywhere a HuggingFace tokenizer is expected:
outputs = tokenizer(["Hello", "world"], return_tensors="pt", padding=True)

For SFT training, Gigatoken reduces 30+ minutes of tokenizer preprocessing to near-zero wall time.

Training (QLoRA SFT with DeepSpeed ZeRO-3 + NVMe Offload)

Due to the 1.65 TB model size, training requires NVMe offloading:

# See train_unsloth.py for full script
torchrun --nproc_per_node=1 train_unsloth.py \
    --output_dir /path/to/output \
    --max_steps 200 \
    --learning_rate 2e-4 \
    --max_seq_length 4096

Key config: DeepSpeed ZeRO-3 with offload_param and offload_optimizer to NVMe, buffer_size=6e9, buffer_count=4, pin_memory=true.
