Sovereign MiMo-4B

4B parameter code reward model pruned from MiMo-7B-RL. Every score passes through ERE P1-P5 verification gates. Every decision is WORM-sealed.

Runs local on RTX 3080 (3.3 GB VRAM). No cloud. No vendor.

Overview

Base Model MiMo-7B-RL
Parameters ~4B (pruned from 7B)
Architecture 24L, 2048H, 16Q/4KV GQA, SwiGLU, RoPE
Quantization GGUF Q4_K_M (~2.5 GB)
Max Context 8192 tokens
License AGPL-3.0 | BSL 1.1 | MIT

How It Differs From Base MiMo-7B

  • Pruned: 32L/4096H/32H -> 24L/2048H/16H (GQA 4KV)
  • FSM Pipeline: 7-stage PREFLIGHT -> REASON -> SEAL -> RESPOND with HMAC-SHA256
  • ERE Gates: P1-P5 verification on every score — halts on failure
  • WORM Chain: Append-only SHA-256 audit on every decision
  • CUDA Kernels: Custom RMSNorm, FlashAttn, SwiGLU, RoPE from hilbert

Verification

  • WORM sealed: Every inference produces an append-only SHA-256 receipt
  • ERE gates: P1-P5 verification on every score
  • Lean 4: Routing tensor sovereign-qra proved zero-sorry
  • Deterministic: Same input -> same output, always

Intended Use

  • Code quality scoring with verified reasoning chains
  • Reward modeling for RLHF with deterministic audit trails
  • Sovereign inference where every decision must be inspectable

Limitations

  • Pre-training weights not yet available (architecture + pipeline ready)
  • Benchmarks pending first training run
  • Requires sovereign stack components for full ERE/WORM integration
