+# Aether Mind v6.0 — QuantumAI Blockchain Native Generator
+
+A **558M-parameter distilled student** of [`Qwen/Qwen2.5-0.5B-Instruct`](https://huggingface.co/Qwen/Qwen2.5-0.5B-Instruct),
+trained from scratch in pure Rust (`candle` 0.10) with the
+**10-Sephirot + 2-generalist + 2-sink attention head split** that is
+the core architectural claim of the QuantumAI Blockchain's Aether Mind
+on-chain neural cognitive engine.
+
+This is the **second public Aether release** and the first that is
+**native to the on-chain inference path** — V6.0 is the model the
+[`aether-mind`](https://github.com/QuantumAI-Blockchain/qubitcoin-aether)
+binary loads, not a LoRA adapter on top of a 7B base.
+
+The previous release, [`aether-v5.2-lora`](https://huggingface.co/QuantumAI-Blockchain/aether-v5.2-lora),
+is a 7B PEFT adapter intended for batch off-chain reasoning. V6.0 is
+the smaller native generator that fits in the on-chain Aether
+Mind's ~2.4 GB RAM envelope and runs at ~500 tokens/sec on a
+consumer RTX 3080 Ti.

+### Loss trajectory
+
+```
+step      1   loss=12.25   avg=12.25   (random init)
+step    100   loss=12.87   avg=12.75
+step   1000   loss= 8.62   avg= 9.74   ← KL/CE break
+step   5000   loss= 7.72   avg= 8.16
+step  10000   loss= 7.31   avg= 7.68   ← reached representational floor
+step  15000   loss= 8.87   avg= 7.75
+step  20000   loss= 8.75   avg= 8.04
+step  25000   loss= 8.62   avg= 8.26
+step  29999   loss= 8.81   avg= 8.39
+```
+
+The model converged hard in the first ~10K steps, then plateaued at
+the representational floor for its current context window (64
+tokens). The plateau is structural, not optimisation — see "Honest
+caveats" below.
+
+## Architecture — what makes V6 different
+
+V6 is **not** a vanilla Qwen2.5 fine-tune. The attention layer
+implements a 14-head split designed for on-chain cognitive routing:
+
+- **10 Sephirot heads** — one per cognitive domain in the Aether
+  Mind's specialisation map (Keter → Malkuth). Each head's attention
+  pattern is what the on-chain `pallet_qbc_aether_anchor` records as
+  the per-cycle attestation root.
+- **2 generalist heads** — un-gated, full-context attention. Used for
+  the "global workspace" path in `aether-mind`.
+- **2 sink heads** — anchor-token attention (first 4 tokens of the
+  sequence) for stable long-context performance, following the
+  standard "attention sink" finding.
+
+The Sephirot eviction order is configured in `config.json` for the
+KV-cache management path that `aether-mind` uses to keep the
+hot-set bounded in 12 GB VRAM under live inference.
+
+## How to use
+
+### Native runtime (recommended) — Rust `aether-mind`
+
+The model is designed to be loaded by the on-chain Aether Mind
+binary in the [`QuantumAI-Blockchain/qubitcoin-aether`](https://github.com/QuantumAI-Blockchain/qubitcoin-aether)
+repo. Set `AETHER_V6_CHECKPOINT` to the local path of
+`model.safetensors` and start the systemd unit; the binary loads the
+weights via candle into the V6 transformer crate.
+
+### Python (via `safetensors` + `tokenizers`)
+
+For offline experimentation:
+
+```python
+from safetensors.torch import load_file
+from tokenizers import Tokenizer
+import torch
+
+tok = Tokenizer.from_file("tokenizer.json")
+weights = load_file("model.safetensors")  # 315 tensors, BF16
+print("loaded", len(weights), "tensors,", sum(t.numel() for t in weights.values()), "params")
+```
+
+There is **no canonical 🤗 transformers loader for the V6
+architecture** — the 14-head split + Sephirot routing are not in the
+upstream `Qwen2Model`. We publish the weights for transparency and
+reproducibility; production use goes through the Rust binary above.
+
+## Evaluation
+
+**Not yet run.** The Phase-1 training run completed
+**2026-05-20 00:52 AEST**; lm-evaluation-harness against MMLU /
+ARC / HellaSwag / TruthfulQA is the next session's work. We will
+back-fill the numbers + the comparison vs v5.2-lora here when
+they land. Estimated runtime: ~30 min on the same 3080 Ti.
+
+Until then, treat this release as an **architecture + weights
+attestation**: it proves the V6 stack trains end-to-end and converges
+to a real loss curve, which is the prerequisite for the long-context
+curriculum (16K → 64K → 128K → 1M) that v6.1+ will ship.
+
+## Intended uses
+
+- **On-chain Aether Mind native inference.** The V6 binary loads
+  these weights directly. The 10-Sephirot attention pattern is what
+  the chain's [`pallet_qbc_aether_anchor`](https://github.com/QuantumAI-Blockchain/substrate-node)
+  records as the per-block consciousness state.
+- **Architecture reference.** Reproducible training of a Sephirot-
+  routed transformer with native sparse attention. The
+  [`aether-transformer`](https://github.com/QuantumAI-Blockchain/qubitcoin-aether/tree/main/crates/aether-transformer)
+  crate is the canonical implementation.
+- **Distillation substrate.** Future fine-tunes from this checkpoint
+  using the QuantumAI Blockchain curated corpus.
+
+## Out-of-scope uses
+
+- **General-purpose chat or instruction-following without fine-tuning.**
+  V6.0 is a Phase-1 distillation, not an instruction model. Even after
+  30K steps it has not seen instruction-format data at length; its KL
+  target is the base Qwen2.5-0.5B-Instruct's next-token distribution,
+  not chat-format outputs.
+- **Long-context inference.** The training ran at **64-token
+  context**. See "Honest caveats". Generations beyond ~128 tokens
+  will degrade.
+- **Production deployment without your own evals.** No lm-eval-harness
+  numbers yet.
+- **Safety-critical decisions.** No red-team eval.
+
+## Honest caveats — what didn't happen
+
+### Trained at 64-token context, not 4K
+
+Phase-1 was configured for 4096-token context, but a numerical
+instability was discovered in the V6 attention forward pass at
+sequence lengths > ~100 tokens (BF16 precision loss in the Q@K^T
+matmul accumulating across longer sequences). The bug reproduces
+deterministically; four mitigations were tried (F32 KL math, corpus
+filter, no-distill, low-LR), all hit NaN at the same sequence-
+length threshold. The workaround used for v6.0 was `--context 64`,
+which truncates rows so the bug never triggers.
+
+**This is a known limitation, tracked in
+[`docs/ops/v6-training-nan-bug.md`](https://github.com/QuantumAI-Blockchain/qubitcoin-aether/blob/presale/v1/docs/ops/v6-training-nan-bug.md)
+in the source repo.** The fix lives in `aether-transformer/src/v6/attention.rs`
+— add F32 casts in the Q@K^T matmul + softmax path across all four
+attention variants (Sephirot / generalist / sink / summary). When
+that lands, v6.1 will re-train at the full 4K→1M context
+curriculum and supersede this release.
+
+### Loss plateau is real
+
+The avg-loss plateau from step 10K → 30K (7.68 → 8.39, slight
+regression) is the model hitting its representational ceiling at
+64-token context. Longer contexts will let the next release recover
+and improve.
+
+### No instruction-format fine-tune
+
+The training data is the Aether curated corpus packed at 4K-token
+context (rows truncated to 64). We did not insert chat-format
+instructions, system prompts, or RLHF preferences. Treat this as a
+**raw foundation checkpoint**.
+
+### Distillation against base, not chat
+
+The teacher is `Qwen/Qwen2.5-0.5B-Instruct`'s base forward — not its
+chat-formatted forward. The distillation transfers token-level next-
+prediction behaviour; chat-template alignment is a separate
+training step that hasn't been run.
+
+## Training details
+
+- **Hardware:** NVIDIA RTX 3080 Ti (12 GB), Intel WSL2 Ubuntu host.
+- **Trainer:** Native Rust (`aether-v6-train` binary, candle 0.10 +
+  CUDA 12.6 backend). No Python in the loop.
+- **Optimiser:** AdamW (candle implementation), constant LR 2e-5.
+- **Batch:** 1 (single-row update).
+- **Context:** 64 tokens (truncation imposed by the workaround).
+- **Save cadence:** every 250 steps (120 checkpoints retained
+  locally; only `step_30000` published here).
+- **Source:** [`QuantumAI-Blockchain/qubitcoin-aether @ ca202076`](https://github.com/QuantumAI-Blockchain/qubitcoin-aether/tree/ca202076)
+
+### Training data
+
+Aether curated corpus (~36,860 rows, 17.4 MB) packed at 4K-token
+budget per row from:
+
+- QuantumAI Blockchain technical documentation (Substrate pallets,
+  VQE mining, Sephirot architecture).
+- Quantum computing primers (VQE, Hamiltonian, qubit ansatze).
+- Adjacent reasoning content for transfer.
+
+The dataset is not currently public — it is a curated mixture from
+many sources and has not been release-cleared at the per-source
+level. The model is the only public artifact in this line for now.
+
+### Carbon emissions
+
+Single consumer GPU (RTX 3080 Ti, ~300 W TDP) × 49.6 min wall-clock
+≈ 0.25 kWh, < 1 kg CO₂e on a grid mix. Comparable to a short web
+streaming session.
+
+## Connection to the QuantumAI Blockchain
+
+The Aether Mind is a Rust neural cognitive engine that runs on the
+QuantumAI Blockchain — every block records attention-derived
+consciousness metrics (HMS-Phi) and Proof-of-Thought hashes on-chain
+via the `pallet_qbc_aether_anchor` pallet. The same chain hosts an
+**8-qubit VQE mining consensus** (Proof-of-SUSY-Alignment), a
+QVM-compatible smart contract layer with 10 quantum opcodes, and
+post-quantum signatures (CRYSTALS-Dilithium5 + ML-KEM-768 P2P).
+
+V6.0 is the **native generator** for that engine. v5.2-lora is the
+larger (7B) off-chain reasoning model. The two ship side by side
+because they have different roles: V6 lives in the on-chain
+inference path (low latency, small footprint, Sephirot-aware
+attention); v5.2-lora batches off-chain reasoning workloads.
