+## Post-training
+To provide a systematic overview of our team's work on data and algorithms, we adopt the widely recognized Qwen3.6-35B-A3B as the base model for post-training and build KAT-Coder-V2.5-Dev on top of it. Overall, KAT-Coder-V2.5-Dev largely follows the post-training recipe of KAT-V2.5, with most settings—including data construction, training pipeline, and optimization strategy—remaining unchanged. The full pipeline consists of two stages: supervised fine-tuning (SFT) and reinforcement learning (RL). We first fine-tune Qwen3.6-35B-A3B on a dataset of 127K examples and then perform RL training on the resulting SFT model.
+During the RL stage, we retain the training infrastructure and key technical designs validated in KAT-V2.5, including the following four components:
+1. **Token-in-Token-out (TITO) consistency.** We use TITO to ensure that the token sequences in the rollout and training stages are strictly identical, preventing training discrepancies caused by differences in chat templates, serialization, or tokenizer behavior.
+2. **Truncated Importance Sampling (TIS).** To mitigate policy staleness and off-policy issues introduced by asynchronous rollouts, we apply TIS to truncate importance-sampling weights, reducing the variance and instability caused by excessively large weights.
+3. **Reliable sandboxes and verifiers.** We systematically inspect and validate the stability and correctness of the sandboxes and verifiers. This helps prevent infrastructure failures—such as execution timeouts, environment errors, or verifier misjudgments—from being incorrectly treated as model failures and contaminating the reward signal.
+4. **Hierarchical rewards based on harness execution feedback.** We construct hierarchical rewards from fine-grained execution feedback provided by the harness. This allows the model to optimize toward the final task objective while also receiving credit for meaningful progress in unsuccessful trajectories, thereby increasing the training value of failed attempts and providing denser reward signals.
+However, Qwen3.6 exhibits trajectory patterns that differ from those observed in KAT-V2.5, requiring additional reward adaptations tailored to its behavior. In our initial experiments, a simple binary 0–1 reward caused model collapse as early as the second epoch. An analysis of the training trajectories revealed that, as training progressed, the model increasingly tended to issue a large number of parallel tool calls within a single turn—occasionally exceeding 70 calls. This behavior caused the context length to grow rapidly, generated a substantial number of invalid trajectories and execution errors, and ultimately destabilized RL training.
+To address this issue, we augmented the original hierarchical reward with several Qwen3.6-specific penalties targeting (including but not limited to the following):
+- Excessive parallel tool calls within a single turn;
+- Failed tool calls;
+- Empty tool-call blocks; and
+- Large amounts of repeated content.
+These targeted reward adjustments effectively suppressed pathological tool-use and repetitive-generation behaviors, enabling stable RL training for 10 epochs. Our experiments validate the effectiveness and feasibility of both the overall training pipeline and the Qwen3.6-specific reward design.

+## Quickstart
+For streamlined integration, we recommend using KAT-Coder-V2.5-Dev via APIs. Below is a guide to use KAT-Coder-V2.5-Dev via OpenAI-compatible API.
+### Serving KAT-Coder-V2.5-Dev
+KAT-Coder-V2.5-Dev can be served via APIs with popular inference frameworks. In the following, we show example commands to launch OpenAI-Compatible API servers for KAT-Coder-V2.5-Dev model.
+#### SGLang
+SGLang is a fast serving framework for large language models and vision language models. sglang>=0.5.10 is recommended for KAT-Coder-V2.5-Dev, which can be installed using the following command in a fresh environment:

+```shell
+uv pip install vllm --torch-backend=auto
+```
+The following will create API endpoints at `http://localhost:8000/v1`:
+- Standard Version: The following command can be used to create an API endpoint with maximum context length 262,144 tokens using tensor parallel on 8 GPUs.
+   ```shell
+   vllm serve Kwaipilot/KAT-Coder-V2.5-Dev \
+       --port 8000 \
+       --tensor-parallel-size 8 \
+       --max-model-len 262144 \
+       --reasoning-parser qwen3
+   ```
+- Tool Call: To support tool use, you can use the following command.
+   ```shell
+   vllm serve Kwaipilot/KAT-Coder-V2.5-Dev \
+       --port 8000 \
+       --tensor-parallel-size 8 \
+       --max-model-len 262144 \
+       --reasoning-parser qwen3 \
+       --enable-auto-tool-choice \

+   ```shell
+   vllm serve Kwaipilot/KAT-Coder-V2.5-Dev \
+       --port 8000 \
+       --tensor-parallel-size 8 \
+       --max-model-len 262144 \
+       --reasoning-parser qwen3 \
+       --language-model-only
+   ```
+#### KTransformers
+KTransformers is a flexible framework for experiencing cutting-edge LLM inference optimizations with CPU-GPU heterogeneous computing. For running KAT-Coder-V2.5-Dev with KTransformers, see the KTransformers Deployment Guide.
+#### Hugging Face Transformers
+Hugging Face Transformers contains a lightweight server which can be used for quick testing and moderate load deployment. The latest transformers is required for KAT-Coder-V2.5-Dev:
+```shell
+pip install "transformers[serving]"
+```
+Then, run transformers serve to launch a server with API endpoints at `http://localhost:8000/v1`; it will place the model on accelerators if available:
+```shell
+transformers serve Kwaipilot/KAT-Coder-V2.5-Dev --port 8000 --continuous-batching
+```
+## Using KAT-Coder-V2.5-Dev via the Chat Completions API
+The chat completions API is accessible via standard HTTP requests or OpenAI SDKs. Here, we show examples using the OpenAI Python SDK.
+Before starting, make sure it is installed and the API key and the API base URL is configured, e.g.:
+```shell
+pip install -U openai
+# Set the following accordingly
+export OPENAI_BASE_URL="http://localhost:8000/v1"
+export OPENAI_API_KEY="EMPTY"
+```
+### Text-Only Input
+```python
+from openai import OpenAI
+# Configured by environment variables
+client = OpenAI()
+messages = [
+    {"role": "user", "content": "Type \"I love KAT-Coder-V2.5-Dev\" backwards"},
+]
+chat_response = client.chat.completions.create(
+    model="Kwaipilot/KAT-Coder-V2.5-Dev",
+    messages=messages,
+    max_tokens=81920,
+    temperature=1.0,
+    top_p=0.95,
+    presence_penalty=1.5,
+    extra_body={
+        "top_k": 20,
+    },
+)
+print("Chat response:", chat_response)
+```
+## Instruct (or Non-Thinking) Mode
+KAT-Coder-V2.5-Dev will think by default before response. You can obtain direct response from the model without thinking by configuring the API parameters. For example,
+```python
+from openai import OpenAI
+# Configured by environment variables
+client = OpenAI()
+messages = [
+    {"role": "user", "content": "Write a Python function that returns the n-th Fibonacci number."},
+]
+chat_response = client.chat.completions.create(
+    model="Kwaipilot/KAT-Coder-V2.5-Dev",
+    messages=messages,
+    max_tokens=32768,
+    temperature=0.7,
+    top_p=0.8,
+    presence_penalty=1.5,
+    extra_body={
+        "top_k": 20,
+        "chat_template_kwargs": {"enable_thinking": False},
+    },
+)
+print("Chat response:", chat_response)
+```
+## Preserve Thinking
+By default, only the thinking blocks generated in handling the latest user message is retained, resulting in a pattern commonly as interleaved thinking. KAT-Coder-V2.5-Dev has been additionally trained to preserve and leverage thinking traces from historical messages. You can enable this behavior by setting the preserve_thinking option:
+```python
+from openai import OpenAI
+# Configured by environment variables
+client = OpenAI()
+messages = [...]
+chat_response = client.chat.completions.create(
+    model="Kwaipilot/KAT-Coder-V2.5-Dev",
+    messages=messages,
+    max_tokens=32768,
+    temperature=0.7,
+    top_p=0.8,
+    presence_penalty=1.5,
+    extra_body={
+        "top_k": 20,
+        "chat_template_kwargs": {"preserve_thinking": True},
+    },
+)
+print("Chat response:", chat_response)
+```
+This capability is particularly beneficial for agent scenarios, where maintaining full reasoning context can enhance decision consistency and, in many cases, reduce overall token consumption by minimizing redundant reasoning. Additionally, it can improve KV cache utilization, optimizing inference efficiency in both thinking and non-thinking modes.
+## Processing Ultra-Long Texts
+KAT-Coder-V2.5-Dev natively supports context lengths of up to 262,144 tokens. For long-horizon tasks where the total length (including both input and output) exceeds this limit, we recommend using RoPE scaling techniques to handle long texts effectively, e.g., YaRN.
+YaRN is currently supported by several inference frameworks, e.g., transformers, vllm, ktransformers and sglang. In general, there are two approaches to enabling YaRN for supported frameworks:
+- Modifying the model configuration file: In the config.json file, change the rope_parameters fields in text_config to:
+   ```json
+   {
+       "mrope_interleaved": true,
+       "mrope_section": [
+           11,
+           11,
+           10
+       ],
+       "rope_type": "yarn",
+       "rope_theta": 10000000,
+       "partial_rotary_factor": 0.25,
+       "factor": 4.0,
+       "original_max_position_embeddings": 262144
+   }
+   ```
+- Passing command line arguments:
+    For vllm, you can use
+    ```shell
+    VLLM_ALLOW_LONG_MAX_MODEL_LEN=1 vllm serve ... --hf-overrides '{"text_config": {"rope_parameters": {"mrope_interleaved": true, "mrope_section": [11, 11, 10], "rope_type": "yarn", "rope_theta": 10000000, "partial_rotary_factor": 0.25, "factor": 4.0, "original_max_position_embeddings": 262144}}}' --max-model-len 1010000
+    ```
+    For sglang and ktransformers, you can use
+    ```shell
+    SGLANG_ALLOW_OVERWRITE_LONGER_CONTEXT_LEN=1 python -m sglang.launch_server ... --json-model-override-args '{"text_config": {"rope_parameters": {"mrope_interleaved": true, "mrope_section": [11, 11, 10], "rope_type": "yarn", "rope_theta": 10000000, "partial_rotary_factor": 0.25, "factor": 4.0, "original_max_position_embeddings": 262144}}}' --context-length 1010000
+    ```
