The obvious approaches are (a) actually writing skip list logic in a PL/pgSQL body, or (7) making PostgreSQL itself do the work — a declarative schema + functions that operate on *sets*, using CTEs to find predecessors at every level in one statement.

GLM-5.3-Flash On-Policy Harvest
On-policy responses generated by zai-org/GLM-5.3-Flash (reference FP8 weights, vLLM day-0 image, temperatures cycled 0.6/0.8/0.95/1.05), built as training text for speculative-decoding drafter heads (DFlash2 / DSpark family): the drafter learns to predict what the target model actually generates.
Companion page: glm53-flash-internals — a measured profile of the same model's internals (activation landscapes, attention-sink anatomy, FP8 margins to 260k context, sparse-indexer selection maps), produced with Claude Code and Spectra Scope.
The corpus ships in two rounds:
| round | file | status |
|---|---|---|
| Round 1 — balanced base | data/glm53_harvest.parquet |
✅ complete |
| Round 2 — coverage expansion | data/glm53_harvest_r2.parquet |
✅ complete |
Round 1 — available now
46,611 responses / 60,945,988 generated tokens, zero errors (harvested 2026-08-30). Single-turn, thinking disabled, 1,600-token generation cap, synthetic prompt bank (deterministic combinatorics, seed 42).
| register | rows | tokens | share |
|---|---|---|---|
| code (8 languages) | 13,846 | 20.7M | 34.0% |
| prose / creative | 12,546 | 17.7M | 29.0% |
| structured (JSON/tables/plans/specs) | 9,299 | 12.4M | 20.4% |
| chat / general | 7,087 | 6.3M | 10.3% |
| music / lyrics | 3,754 | 3.7M | 6.1% |
| operator (CLI/agent-flavored) | 79 | 0.07M | 0.1% |
Round 2 — available now
18,858 responses / 56,434,338 generated tokens (harvested 2026-08-30; budget-limited
run over a 27,462-prompt bank, seed 43, two temperatures per prompt — banked rows are a
uniform sample of the design mix). 9,465 rows (50.2%) ran with thinking enabled,
carrying 39.95M tokens of inline <think>…</think> chains. 1,709 rows are Chinese.
| register | rows | tokens |
|---|---|---|
| code (14 languages) | 4,139 | 17.5M |
| prose / creative | 3,377 | 12.0M |
| reasoning / math | 3,187 | 10.0M |
| agentic / tool-calling | 1,745 | 5.5M |
| zh (Chinese, mixed registers) | 1,709 | 5.1M |
| chat (open-perfectblend prompts) | 3,054 | 2.8M |
| structured | 911 | 2.7M |
| music / lyrics | 646 | 0.7M |
| multiturn | 90 | 0.06M |
Combined corpus: 65,469 responses / 117,380,326 tokens. What round 2 adds:
- Thinking-mode coverage: ~48% of prompts run with reasoning enabled — responses
carry the full inline
<think>…</think>chain before the answer. Round 1 is 100% thinking-off; combined, the corpus covers both serving modes. - New registers: synthetic reasoning/math (step-by-step derivations), agentic/tool-calling (JSON tool-call transcripts against declared tool schemas), Chinese (zh) across code/chat/prose/reasoning, and multi-turn conversations (contexts drawn from the open-perfectblend prompt spine; final assistant turn regenerated on-policy).
- Boosted: fresh code (14 languages), prose (new forms: second-person, dialogue-led, flash fiction, poem cycles), and chat (open-perfectblend prompts).
- Longer generations: per-register caps 1,600–2,560, raised to 6,144 for thinking rows — round 1's truncation rate does not repeat.
Quick start
from datasets import load_dataset
ds = load_dataset("Zek-Takai/glm53-flash-harvest", data_files="data/*.parquet", split="train")
# Only thinking-mode responses (full inline <think> chains):
thinking = ds.filter(lambda r: r.get("thinking"))
Format
Two Parquet files (zstd), one unified schema:
| column | type | description |
|---|---|---|
| id | string | register-prefixed prompt id |
| register | string | code / prose / music / structured / chat / operator / reasoning / agentic / zh / multiturn |
| lang | string | en / zh |
| thinking | bool | response contains an inline <think>…</think> chain |
| turns | int32 | context turns (1 = single-turn; >1 = multi-turn) |
| temp | float32 | sampling temperature |
| prompt | string | final user prompt |
| response | string | GLM-5.3-Flash response |
| tokens | int32 | completion token count |
| messages_json | string | full chat context for multi-turn rows, else null |
Config map
Pull exactly the slice you want by config name:

Register and thinking configs span both rounds; they are re-shards of the same rows, not additional data.
Prompts
prompts/ holds the exact prompt banks (prompts.jsonl, prompts2.jsonl) and
their deterministic builders (build_prompts.py seed 42; build_prompts2.py
seed 43 + append_multiturn.py seed 44). Round 2 consumed ~34% of its bank.
Provenance & license
Round 1 prompts: synthetic, original. Round 2 prompts: synthetic (code, prose, reasoning, agentic, zh, structured, music) plus human prompt turns from mlabonne/open-perfectblend (via mgoin/open-perfectblend-glm5.2-regen) for the chat and multiturn registers — see the source datasets for underlying prompt licensing. All responses: GLM-5.3-Flash (MIT). Corpus: MIT.
