TestGeniy 4K Context Reasoning Model
TestGeniy is a compact causal language model focused on mathematical reasoning, formal logic, and helpful text interaction.
This main release is the validated 4K-context anchor. It is the safe production checkpoint after context-extension and regression testing.
Release summary
- Context window: 4096 tokens.
- RoPE: extended from 2048 to 4096 positions using the original theta value 500000.
- Attention: sliding attention with block size 1024 and global attention in layers 3, 7, 11, 15, 19, and 23.
- Weights: validated
logic_small_scope_step080 anchor, with context buffers extended to 4096.
- Evaluation questions were kept out of training.
- This main release does not include the rejected synthetic-CoT candidates.
Validation
The 4K model remained finite on full 4096-token forward passes and answered a 3157-token long-context probe correctly.
Fixed paired reasoning gate, 12 examples per dataset:
| Benchmark | Anchor | 4K main |
|---|
| GSM8K | 2/12 | 2/12 |
| MATH-500 | 2/12 | 2/12 |
| ARC-Challenge | 5/12 | 5/12 |
| FOLIO | 4/12 | 4/12 |
The release is a verified context-capability improvement with no measured regression on this gate. It is not presented as a benchmark-accuracy improvement.
Intended use
Use this checkpoint for compact English reasoning experiments, long-context prompting up to 4096 tokens, and further controlled fine-tuning.
Limitations
This is a small research model. It can produce incorrect reasoning or answers, especially on difficult mathematics and formal logic. The benchmark gate above is a regression gate, not a broad capability estimate.
Provenance
Base checkpoint: logic_small_scope_step080 from this project. The published weights contain no benchmark questions and no synthetic-CoT training data.
Budgie Alignment v2 research handoff
A later, gate-driven Budgie-500M post-training research track is stored under candidates/budgie-alignment-v2/.
Start with the comprehensive Budgie Alignment v2 README. It documents the current research leader, exact checkpoint lineage, evaluation protocols, confidence intervals, training-source policy, Qwen3.8+DFlash2 teacher setup, retained and rejected experiments, known limitations, and recommended next steps for a human or another AI agent.
These research candidates do not replace this root checkpoint automatically.
