The failure that built v10
v9 was asked for a LEFT JOIN analytical query:
-- "List every customer, their total completed spending, sort by spending desc"
It returned:
SELECT c.id, c.name, COALESCE(o.total, 0) AS total_spending
FROM customers c
LEFT JOIN orders o ON c.id
-- ...truncated. Dead.
The correct answer:
SELECT c.id, c.name, COALESCE(SUM(o.total), 0) AS total_spending
FROM customers c
LEFT JOIN orders o ON c.id = o.customer_id AND o.status = 'completed'
GROUP BY c.id, c.name
ORDER BY total_spending DESC, c.id ASC;
v9 couldn't do multi-clause analytical queries. v10 can.
🎯 What v10 adds
Where v9 added write capability (INSERT/UPDATE/DELETE), v10 adds complex analytical queries:
- LEFT JOIN + GROUP BY + COALESCE — the exact v9 failure mode, now handled
- HAVING filters — post-aggregation conditions
- Subquery comparisons — nested analytical logic
- Complex ORDER BY — multi-column, expression-based sorting
- Multi-table JOINs — beyond simple two-table patterns
📊 The numbers
| Model | Held-out (telemetry) | Protocol | Execute rate | Invented cols |
|---|---|---|---|---|
| imagine-v8 | 50.0% (20/40) | 100% | — | — |
| imagine-v9 | 90.0% (36/40) | 100% | 97.5% | 0 |
| imagine-v10 | 100.0% (40/40) | 100% | 100% | 0 |
Perfect score. Zero wrong answers. Zero hallucinations. Zero refusals.
🧬 How v10 was built
Two-stage fine-tuning from Interchained/imagine-v9:
Stage 1 — Full fine-tune (smoke)
- Corpus: 3,216 admitted pairs (99.94% gate admit rate)
- New: Analytical query templates (LEFT JOIN aggregations, HAVING, subqueries)
- Epochs: 3, LR 1e-5, cosine schedule
- Final loss: 0.0052 (v9 was 0.0320 — 6x better)
- Time: 4.1 min on H200, 26k tok/s
Stage 2 — LoRA refinement
- Base: v10-smoke checkpoint
- Rank: 16, LR 5e-6
- Epochs: 3
- Final loss: 0.0244
- Time: 5.4 min on H200
- Adapter folded into full checkpoint
The corpus
3,218 candidates forged, 3,216 admitted:
| Schema | Templates | Writes | Total |
|---|---|---|---|
| shop | 356 | 388 | 744 |
| clinic | 545 | 290 | 835 |
| library | 481 | 257 | 738 |
| fleet | 297 | 226 | 523 |
| audit | 252 | 126 | 378 |
Nothing enters training that a live database hasn't agreed with.
🔬 The execution gate
Every candidate goes through L0–L4:
candidate SQL ──► L0 real PostgreSQL parser not a regex
L1 read-only + bounded no writes, no sleeps
L2 EXPLAIN on live schema hallucinations die HERE
L3 execute, timed, capped real rows
L4 SAME ANSWER as ref? ◄── the one that matters
▼
admitted to corpus
68/68 gate tests passing. The gate is the truth authority — not a bigger model, not vibes.
📦 Output protocol
SQL wrapped in sentinel blocks:
<<<SQL>>>
SELECT c.id, c.name, COALESCE(SUM(o.total), 0) AS total_spending
FROM customers c
LEFT JOIN orders o ON c.id = o.customer_id AND o.status = 'completed'
GROUP BY c.id, c.name
ORDER BY total_spending DESC, c.id ASC;
<<<END>>>
Can also refuse:
| block | meaning |
|---|---|
<<<SQL>>> | here is your query |
<<<UNANSWERABLE>>> | this schema cannot answer that |
<<<CLARIFY>>> | ambiguous — here's what's missing |
⚠️ A truncated generation is not an answer. An unterminated block extracts to nothing.
💻 Loading v10
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model_id = "Interchained/imagine-v10"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16,
device_map="auto",
)
# Ask for an analytical query
prompt = """Schema:
customers(id, name)
orders(id, customer_id, total, status)
List every customer ID, name, and total completed spending.
Include customers with no completed orders (show 0).
Sort by spending descending, then ID ascending."""
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
with torch.no_grad():
output = model.generate(inputs["input_ids"], max_new_tokens=256, do_sample=False)
print(tokenizer.decode(output[0], skip_special_tokens=True))
🎯 Identity
The deployed model identity is Imagine.
Built and fine-tuned by Interchained.
DeepSeek-Coder is part of the upstream lineage (via v8 → v9 → v10), but the deployed identity is Imagine.
⚡ Local-first
Runs on your hardware. No API key. No metered inference. No cloud dependency.
📐 The rules
1 · Don't write a verifier — the engine already shipped one. Real parser. Real planner. Real rows.
2 · Assert the property, not a proxy. Execution accuracy, not string similarity.
3 · Schema goes in the prompt, not in the weights. The model learns "read the schema you were handed" — not memorise ours.
⚠️ Limitations
v10 is a research checkpoint. It may still:
- generate incorrect SQL on novel patterns
- misunderstand ambiguous requests
- produce writes with wrong
WHEREclauses — always review before executing
Generated SQL should be reviewed before use in production. This applies doubly to writes.
🔒 Security
Do not rely on model behavior alone for database safety. Production systems should enforce:
- least-privilege database roles
- statement timeouts and row limits
- query validation and schema restrictions
- application-level authorization
- audit logging
- human approval for all write statements
