Libraries

How to use modrill/code-think-o7b-20260908 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="modrill/code-think-o7b-20260908")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("modrill/code-think-o7b-20260908")
model = AutoModelForCausalLM.from_pretrained("modrill/code-think-o7b-20260908", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

+# CodeThink-V4-OLMo-3-7B
+Research checkpoint: **allenai/Olmo-3-1025-7B** (`a81bae42db3975be1671e27b9c9a56da1a9f980f`) after V4 LoRA SFT on Qwen3-30B-A3B-Thinking-2507 traces (OLMo-tokenized V4 payload), then merged to full weights.
+Repo name uses **OLMo-3** because `RUN_IDENTITY.model.hf_id` is `allenai/Olmo-3-1025-7B` (not OLMo-2).
+This is a **research checkpoint, not a product**. Single-seed diagnostic numbers only. Do not treat DEV256 as a leaderboard claim.
+License: **Apache-2.0**, inherited from [allenai/Olmo-3-1025-7B](https://huggingface.co/allenai/Olmo-3-1025-7B) (verified from the local base `README.md`: `license: apache-2.0`).
+## Base, teacher, and data
+| | |
+|---|---|
+| Student | `allenai/Olmo-3-1025-7B` revision `a81bae42db3975be1671e27b9c9a56da1a9f980f` |
+| Teacher | `Qwen/Qwen3-30B-A3B-Thinking-2507` traces (V4 paired think payload, OLMo renderer / tokenizer) |
+| Problems | **4715** unique problems (`source_1ep_rows`); physical 2-epoch concat = **9430** rows |
+| Dose | **31,689,386** assistant tokens / epoch (OLMo tokenizer; not the Qwen 32.4M count); endpoint **63,378,772** assistant tokens (2 epochs) |
+| Train seed | **42** |
+## Recipe
+- LoRA **r64 / α128**, dropout 0.0, seven projections: `q_proj`, `k_proj`, `v_proj`, `o_proj`, `gate_proj`, `up_proj`, `down_proj`
+- Embeddings / `lm_head` frozen except **two-sided trainable B-row** for **100257** (`<|endoftext|>`). Token id from `adapter/TOKEN_ROWS_META.json`.
+- Assistant supervised tail: `<|endoftext|>` (**100257**)
+- LR **1e-4**, AdamW (β 0.9/0.95), **cosine** over assistant-token dose, **warmup 6%** (3,802,726 / 63,378,772 tokens), weight decay **0.1**
+- **bf16**, no packing, no truncation, context 32768 at train time
+- **2 epochs**, physical concat. Endpoint-only score; no checkpoint picking.
+- Chat template: `olmo3-lcb-noprefill` (no generation-prompt `<think>` prefill). Bundled as `chat_template.jinja`.
+Merged weights are the 2-epoch endpoint (`step-000904`, 63,378,772 assistant tokens). LoRA + B-row are under `adapter/`.
+## Evaluation (DEV256)
+256-problem LiveCodeBench-derived **dev** split. Seed **3407**, **think** mode, **no `<think>` prefill**, max generation ~32k, sandbox-verified **pass@1**. Temperature 0.6, top-p 0.95, top-k 20.
+**Cap** = generations that hit the 32k length limit without closing `</think>`.
+| Model | pass@1 | Cap | Notes |
+|---|---:|---:|---|
+| **CodeThink-V4-OLMo-3-7B** | **56/256** | **149** | this repo; seed 3407 |
+| Olmo-3-1025-7B (same contract, think) | 15/256 | 104 | bare base, seed 3407 |
+Single seed. These are research checkpoints, not product scores.
+## Usage
+Merged full weights; no PEFT required at inference. The pinned OLMo template supplies a default system turn. **Do not** prefill `<think>`.
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+repo = "modrill/CodeThink-V4-OLMo-3-7B"
+tokenizer = AutoTokenizer.from_pretrained(repo)
+model = AutoModelForCausalLM.from_pretrained(
+    repo, torch_dtype="bfloat16", device_map="auto"
+)
+messages = [{"role": "user", "content": problem_statement}]
+prompt = tokenizer.apply_chat_template(
+    messages,
+    tokenize=False,
+    add_generation_prompt=True,
+)
+inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+output = model.generate(
+    **inputs,
+    max_new_tokens=32768,
+    do_sample=True,
+    temperature=0.6,
+    top_p=0.95,
+    top_k=20,
+)
+print(tokenizer.decode(output[0][inputs["input_ids"].shape[1]:], skip_special_tokens=False))
+```
+Stop ids used in the official eval: `100257` (`<|endoftext|>`), `100265` (`<|im_end|>`).
+## Repo layout
+- Root: merged HF weights (`config.json`, `model.safetensors`, tokenizer, `generation_config.json`, `chat_template.jinja`) plus `OFFICIAL_MERGE_RECEIPT.json`
+- `adapter/`: LoRA, `token_rows_both_sides.safetensors`, `TOKEN_ROWS_META.json`, checkpoint `MANIFEST.json`
+- `provenance/`: train `RUN_IDENTITY.json`, `TRAINING_CONFIG.json`, `POLICY.json`; DEV256 `COMPLETE.json`
+- `MANIFEST.sha256`
+Optimizer / resume states are **not** included.
