# ORCA6 v0.1-rc1

ORCA6 is an orchestration-advisor model project focused on AI tool selection,
workflow architecture, RAG design, model-routing tradeoffs, and developer
automation strategy.

Current best local adapter:

```text
qwen3_14b_orca_refusal_smoke/
```

This checkpoint is a guarded local release candidate, not a broad public-quality
model. It should be used with the source-packet runtime guard documented in the
evaluation report, runbook, and local adapter CLI.

## Intended Use

- Recommend orchestration patterns for AI developer workflows.
- Compare tools such as n8n, LangGraph, LiteLLM, Qdrant, Langfuse, Promptfoo,
  MCP servers, local inference stacks, and related infrastructure.
- Provide architecture tradeoffs, implementation plans, and conservative next
  steps.

## Not Intended For

- Executing code or tools directly.
- Legal, medical, financial, or safety-critical decisions.
- General code-completion benchmarks unrelated to orchestration.

## Training Data

- SFT train rows: 41
- SFT validation rows: 3
- DPO preference rows: 30
- Preference source: auto-graded bootstrap preferences
- Corpus source: GitHub documentation chunks from the ORCA6 pilot retrieval set.
- Final SFT source mix: `{"graded_preference": 27, "grounded_sft_builder": 8, "refusal_sft_builder": 6}`
- Final answer word count: min=102, max=239, avg=187.05
- Grounded SFT rows include retrieved-evidence citation examples and refusal
  hard negatives for empty evidence, unsupported claims, high-risk automation,
  medical-record access, and certification/compliance claims.

## Models and Infrastructure Used

| Role | Model / System | Notes |
|---|---|---|
| Initial smoke base | `Qwen/Qwen2.5-0.5B-Instruct` | Small-model SFT smoke path validation. |
| Attempted 14B base | `Qwen/Qwen2.5-14B-Instruct` | Initial fetch was too slow/stalled; not the release base. |
| Release base | `Qwen/Qwen3-14B` | Official adapter base and Hugging Face `base_model`. |
| Local downloaded base path | `.cache/orca6-qwen3-14b-download` | Local path used by current helper defaults; historical run used `/tmp/orca6-qwen3-14b-download`. |
| Preference/judge/bootstrap generation | `qwen3-coder:30b` via Ollama | Used for local answer generation / auto-graded bootstrap preference data. |
| Embedding model | `nomic-embed-text:latest` via Ollama | Used to embed pilot corpus chunks into Qdrant. |
| Fine-tuning stack | Unsloth + TRL SFTTrainer + PEFT LoRA / QLoRA | 4-bit training profile on local RTX 3090. |

## Training Rounds

| Round | Base model | Adapter output | Rows | Validation rows | Profile | Final loss | Eval / pass result |
|---|---|---|---:|---:|---|---|---|
| Small-model smoke | `Qwen/Qwen2.5-0.5B-Instruct` | `qwen_finetuned_v0_smoke2/` | 27 | 3 | smoke SFT | `eval_loss=1.762`, `train_loss=2.260`, 14 steps | Pipeline smoke only |
| Qwen3 14B smoke | `Qwen/Qwen3-14B` | `qwen3_14b_orca_smoke/` | 27 | 3 | 14B LoRA smoke | `eval_loss=1.264`, `train_loss=1.537`, 14 steps | 8 held-out prompts generated; quality not release-ready |
| Grounded fit-check | `Qwen/Qwen3-14B` | `qwen3_14b_orca_grounded_smoke/` | 35 | 3 | `seq_length=512`, `lora_r=16`, `lora_alpha=32`, `lora_dropout=0`, grad accum 2 | `eval_loss=1.211`, `train_loss=1.592`, 36 steps | Grounded eval 11/12 = 91.7% |
| Refusal fit-check / release adapter | `Qwen/Qwen3-14B` | `qwen3_14b_orca_refusal_smoke/` | 41 | 3 | `seq_length=512`, `lora_r=16`, `lora_alpha=32`, `lora_dropout=0`, grad accum 2 | `eval_loss=1.206`, `train_loss=1.510`, 42 steps | Guarded eval 12/12 = 100.0%; expanded release eval 54/54 = 100.0% |

Earlier 2048-token/r64 and 1024-token/r32 grounded-profile attempts hit CUDA OOM
with the longer grounded examples. The release fit-check profile settled on 512
tokens and LoRA rank 16 on the RTX 3090.

## Retrieval and Vector Database Stack

The model was trained and evaluated around a source-packet workflow rather than
free-form citation generation.

| Component | Setting |
|---|---|
| Vector database used for active retrieval | Qdrant |
| Qdrant collection | `orca6_pilot` |
| Embedding model | `nomic-embed-text:latest` through Ollama |
| Embedding dimension | 768 |
| Vector distance | Cosine |
| Lexical retrieval | In-process BM25 over `data/pilot_orchestration_chunks.jsonl` |
| Rank fusion | Reciprocal-rank fusion plus exact-match/domain-cue boosts |
| Vector DBs represented in corpus/tool coverage | Qdrant, Chroma, Weaviate, pgvector |
| Other retrieval/RAG tools represented | LlamaIndex, Ragas, LangGraph, Langfuse, LangSmith, Promptfoo, LiteLLM, Ollama, llama.cpp, vLLM |

### Evaluation Matrix

| Evaluation | Passed | Total | Pass rate | Notes |
|---|---:|---:|---:|---|
| Retrieval calibrated pass@1 | 14 | 20 | 70.0% | Smoke retrieval exact/semantic check |
| Retrieval calibrated pass@3 | 20 | 20 | 100.0% | Re-check matched recorded metrics |
| Retrieval calibrated pass@5 | 20 | 20 | 100.0% | Re-check matched recorded metrics |
| Retrieval all-expected@3 | 19 | 20 | 95.0% | Multi-expected query coverage |
| Retrieval all-expected@5 | 20 | 20 | 100.0% | Multi-expected query coverage |
| Grounded adapter, unguarded | 11 | 12 | 91.7% | Pre-refusal grounded adapter; failed one empty-evidence hard negative |
| Refusal adapter, unguarded | 11 | 12 | 91.7% | Still failed one empty-evidence high-risk citation case |
| Refusal adapter + runtime guard | 12 | 12 | 100.0% | 8/8 source-packet, 4/4 hard-negative |
| Expanded release grounded eval | 54 | 54 | 100.0% | 50/50 source-packet, 4/4 hard-negative |

Unguarded refusal eval passed 11/12. The remaining unguarded failure was an
empty-evidence, high-risk payment automation prompt where the model invented a
source citation. The current gate therefore requires the runtime source-packet
guard.

## Limitations

- The current dataset is small and should be treated as a v0 bootstrap.
- Auto-graded preferences are useful for pipeline validation but should be
  replaced or supplemented with human preference labels.
- Recommendations are only as current as the indexed source corpus.
- The adapter is not intended for unguarded citation-heavy answering. Use a
  runtime prompt guard that forbids invented source IDs, URLs, integrations,
  certifications, guarantees, and high-risk actions without retrieved evidence.
- The model must not execute tools or approve irreversible actions.
