+---
+
+## Overview
+
+Axolotl supports on-demand checkpoint saving during training. You can trigger checkpoints via file-based triggers (for programmatic control) or Control+C (for interactive use).
+
+## File-Based Checkpoint Trigger
+
+### Configuration
+
+Enable in your config:
+
+```yaml
+dynamic_checkpoint:
+  enabled: true
+  check_interval: 100  # Optional: check every N steps (default: 100)
+  trigger_file_path: "axolotl_checkpoint.save"  # Optional: custom filename
+```
+
+**Options:**
+- `enabled`: `true` to enable (required)
+- `check_interval`: Steps between file checks. Default: 100. Lower = faster response, higher I/O overhead.
+- `trigger_file_path`: Custom trigger filename. Default: `axolotl_checkpoint.save`
+
+### How It Works
+
+1. Rank 0 checks for trigger file every `check_interval` steps in `output_dir`
+2. When detected, file is deleted and checkpoint is saved
+3. In distributed training, rank 0 broadcasts to synchronize all ranks
+
+### Usage
+
+**Command line:**
+```bash
+touch /path/to/output_dir/axolotl_checkpoint.save
+```
+
+**Programmatic:**
+```python
+from pathlib import Path
+Path("/path/to/output_dir/axolotl_checkpoint.save").touch()
+```
+
+Checkpoint saves within the next `check_interval` steps. The trigger file is auto-deleted after detection, so you can create it multiple times.
+
+**Custom filename:**
+```yaml
+dynamic_checkpoint:
+  enabled: true
+  trigger_file_path: "my_trigger.save"
+```
+```bash
+touch /path/to/output_dir/my_trigger.save
+```
+
+## Control+C (SIGINT) Checkpoint
+
+Pressing `Ctrl+C` during training saves the model state and exits gracefully. **Note:** This saves only the model weights, not optimizer state. For resumable checkpoints, use the file-based trigger.
+
+## Best Practices
+
+- **Check interval**: Lower values (10-50) for fast training, default 100 for slower training
+- **Distributed training**: Create trigger file once; rank 0 handles synchronization
+- **Resume**: Dynamic checkpoints can be resumed like regular checkpoints via `resume_from_checkpoint`
+
+## Example
+
+```yaml
+output_dir: ./outputs/lora-out
+save_steps: 500  # Scheduled checkpoints
+
+dynamic_checkpoint:
+  enabled: true
+  check_interval: 50
+```
+
+This enables scheduled checkpoints every 500 steps plus on-demand saves via file trigger (checked every 50 steps).

+### GDPO
+
+GDPO (Group Reward-Decoupled Policy Optimization) extends GRPO for multi-reward training. It addresses the **reward advantage collapse** problem by normalizing each reward function independently before combining them.
+
+::: {.callout-tip}
+Use GDPO when training with multiple reward functions. For single reward, GRPO and GDPO produce equivalent results.
+:::
+
+Paper: [https://arxiv.org/pdf/2501.05242](https://arxiv.org/pdf/2501.05242)
+
+GDPO uses TRL's native `multi_objective_aggregation` parameter under the hood. When you set `rl: gdpo`, axolotl automatically configures TRL to use `normalize_then_sum` aggregation.
+
+```yaml
+base_model: Qwen/Qwen2.5-1.5B-Instruct
+
+vllm:
+    host: 0.0.0.0
+    port: 8000
+    tensor_parallel_size: 2
+    gpu_memory_utilization: 0.85
+
+rl: gdpo
+
+trl:
+    beta: 0.001
+    max_completion_length: 256
+    use_vllm: true
+    num_generations: 4
+    reward_funcs:
+        - rewards.format_reward
+        - rewards.correctness_reward
+    reward_weights: [1.0, 2.0]
+
+datasets:
+    - path: openai/gsm8k
+      name: main
+      type: rewards.oai_gsm8k_transform
+```
+
+You can also use GRPO with explicit aggregation control:
+
+```yaml
+rl: grpo
+trl:
+    multi_objective_aggregation: normalize_then_sum  # GDPO behavior
+    # or: sum_then_normalize  # Default GRPO behavior
+```
+
+#### GDPO vs GRPO
+
+| Aspect | GRPO | GDPO |
+|--------|------|------|
+| **Aggregation** | `sum_then_normalize` | `normalize_then_sum` |
+| **Multi-reward** | May collapse advantages | Preserves reward signals |
+| **Single reward** | Standard behavior | Equivalent to GRPO |
+
+#### Why GDPO?
+
+When using multiple rewards with GRPO, different reward combinations can produce identical advantages:
+
+```
+# Example: format + correctness rewards
+[format=0, correct=3] → sum=3
+[format=1, correct=2] → sum=3  ← GRPO sees these as equal!
+[format=2, correct=1] → sum=3
+[format=3, correct=0] → sum=3
+```
+
+GDPO normalizes each reward independently, preserving their relative differences.
+
+#### Reward Functions
+
+GDPO uses the same reward function format as GRPO:
+
+```python
+# rewards.py
+def format_reward(completions, **kwargs) -> list[float]:
+    return [1.0 if len(c) > 10 else 0.0 for c in completions]
+
+def correctness_reward(completions, answers, **kwargs) -> list[float]:
+    rewards = []
+    for completion, answer in zip(completions, answers):
+        # Your scoring logic here
+        rewards.append(score)
+    return rewards
+```
+
+#### Sequence Parallelism
+
+GDPO supports sequence parallelism for long-context training:
+
+```yaml
+rl: gdpo
+context_parallel_size: 2
+```
+
 ### SimPO
 
 SimPO uses [CPOTrainer](https://huggingface.co/docs/trl/main/en/cpo_trainer) but with alternative loss function.

+# Finetune GLM-4.6V with Axolotl
+
+GLM-4.6V is a family of vision-language models from ZhipuAI found on [HuggingFace](https://huggingface.co/zai-org/GLM-4.6V). This guide shows how to fine-tune it with Axolotl for vision-language tasks.
+
+
+
+## Getting started
+
+1. Install Axolotl from source following the [installation guide](https://docs.axolotl.ai/docs/installation.html#sec-edge-build).
+
+2. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage.
+
+
+3. Run the fine-tuning:
+
+    glm-4-6v-flash(9B)
+    ```bash
+    axolotl train examples/glm46v/glm-4-6v-flash-qlora.yaml
+    ```
+
+Let us know how it goes. Happy finetuning! 🚀
+
+## Tips
+
+- Vision datasets should follow the format described in the [multimodal docs](https://docs.axolotl.ai/docs/multimodal.html#dataset-format)
+- You can run a **full finetuning** by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
+- Read more on how to load your own dataset in the [dataset loading docs](https://docs.axolotl.ai/docs/dataset_loading.html).
+
+## Supported Models
+
+- **GLM-4.6V**: Full vision-language model (`zai-org/GLM-4.6V`)
+- **GLM-4.6V-Flash**: Faster variant (`zai-org/GLM-4.6V-Flash`)
+
+## Optimization Guides

+# Finetune OpenGV's InternVL with Axolotl
+
+[InternVL 3.5](https://huggingface.co/OpenGVLab/InternVL3_5-8B-HF) is a family of powerful vision-language models supporting dynamic resolution and multi-image understanding by OpenGV. It features a ViT-style vision encoder and strong language model backbone for tasks like visual question answering, OCR, and scene text understanding.
+
+This guide shows how to fine-tune it with Axolotl.
+
+## Getting started
+
+1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
+
+2. Install `timm` for vision model support:
+
+    ```bash
+    pip install timm==1.0.19
+    ```
+
+3. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage.
+
+4. Run the finetuning example:
+
+    ```bash
+    axolotl train examples/internvl3_5/internvl3_5-8b-qlora.yml
+    ```
+
+This config uses about 8.21 GiB VRAM. Let us know how it goes. Happy finetuning! 🚀
+
+### Tips
+
+- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
+- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
+- The dataset format follows the multi-modal format as seen [here](https://docs.axolotl.ai/docs/multimodal.html#dataset-format).

+# Finetune MoonshotAI's Kimi Linear with Axolotl
+
+[Kimi Linear](https://huggingface.co/collections/moonshotai/kimi-linear-a3b) is a MoE model (48B total, 3B active) by MoonshotAI using a hybrid linear attention architecture to achieve a 1M token context length. It uses Kimi Delta Attention (KDA), a refined version of Gated DeltaNet that reduces KV cache size by up to 75% and boosts decoding throughput by up to 6x for long contexts.
+
+This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
+
+**Note:** Axolotl uses experimental training code for Kimi Linear as their original modeling code is inference-only.
+
+## Getting started
+
+1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
+
+2. Install CCE via [docs](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy)
+
+3. Run the finetuning example:
+
+    ```bash
+    axolotl train examples/kimi-linear/kimi-48b-lora.yaml
+    ```
+
+This config uses about 98.7GiB VRAM.
+
+Let us know how it goes. Happy finetuning!
+
+### TIPS
+
+- Kimi Linear requires `trust_remote_code: true`.
+- You can run a full finetuning by removing the `adapter: lora` and `load_in_8bit: true`.
+- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html)
+- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template)
+
+## Optimization Guides
+
+See 👉 [docs](https://docs.axolotl.ai/docs/optimizations.html).
+
+## Limitations
+
+This is not yet compatible with MoE kernels from transformers v5.

+# Finetune Katanemo's Plano-Orchestrator with Axolotl
+
+[Plano-Orchestrator](https://huggingface.co/collections/katanemo/plano-orchestrator) is a family of 4B and 30B-A3B routing and orchestration models designed for multi-agent systems. It analyzes user intent and conversation context to make precise routing decisions, excelling at multi-turn context understanding, multi-intent detection, and context-dependent routing.
+
+This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
+
+## Getting started
+
+1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
+
+2. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage.
+
+3. Run the finetuning example:
+
+    ```bash
+    axolotl train examples/plano/plano-4b-qlora.yaml
+    ```
+
+This config uses about 5.1 GiB VRAM. Let us know how it goes. Happy finetuning! 🚀
+
+### Orchestration Prompt
+
+Plano-Orchestrator uses a specific orchestration prompt format for routing/agent decisions. Please check the [official model card](https://huggingface.co/katanemo/Plano-Orchestrator-4B) for proper prompt formatting and the `ORCHESTRATION_PROMPT` template.
+
+### Tips
+
+- To use the larger [Plano-Orchestrator-30B-A3B](https://huggingface.co/katanemo/Plano-Orchestrator-30B-A3B) MoE model, simply change `base_model: katanemo/Plano-Orchestrator-30B-A3B` in the config and enable multi-GPU training if needed.
+- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
+- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
+- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).

+### Private Deployment
+```yaml
+swanlab_web_host: https://swanlab.yourcompany.com
+swanlab_api_host: https://api.swanlab.yourcompany.com
+```
+
+---
+
+## Authentication
+
+### Recommended: Environment Variable
+```bash
+export SWANLAB_API_KEY=your-api-key
+export SWANLAB_LARK_WEBHOOK_URL=https://open.feishu.cn/...
+export SWANLAB_LARK_SECRET=your-webhook-secret
+```

+```yaml
+swanlab_api_key: your-api-key
+swanlab_lark_webhook_url: https://open.feishu.cn/...
+swanlab_lark_secret: your-webhook-secret
+```
+
+---
+
+## Common Use Cases
+
+### Use Case 1: Migrate from WandB to SwanLab
+Start with `lora-swanlab-profiling.yml`, add your model/dataset config, disable WandB:
+```yaml
+use_swanlab: true
+use_wandb: false
+```
+
+### Use Case 2: Analyze DPO Model Outputs
+Use `dpo-swanlab-completions.yml`, adjust completion logging interval based on your training length:
+```yaml
+swanlab_completion_log_interval: 50   # More frequent for short training
+swanlab_completion_log_interval: 200  # Less frequent for long training
+```
+
+### Use Case 3: Optimize Training Performance
+Use `lora-swanlab-profiling.yml`, run multiple experiments with different optimizations:
+- Baseline: `flash_attention: false, gradient_checkpointing: false`
+- Flash Attention: `flash_attention: true`
+- Gradient Checkpointing: `gradient_checkpointing: true`
+- Both: `flash_attention: true, gradient_checkpointing: true`
+
+Compare profiling metrics in SwanLab dashboard.
+
+### Use Case 4: Production RLHF with Team Collaboration
+Use `dpo-swanlab-full-featured.yml`, set up team workspace and Lark notifications:
+```yaml
+swanlab_workspace: ml-team
+swanlab_lark_webhook_url: ...
+swanlab_lark_secret: ...
+```
+
+---
+
+## Viewing Your Experiments
+
+### Cloud Mode
+Visit [https://swanlab.cn](https://swanlab.cn) and navigate to your project.
+
+**Dashboard sections**:
+- **Metrics**: Training loss, learning rate, profiling metrics
+- **Tables**: RLHF completions (for DPO/KTO/ORPO/GRPO)
+- **Config**: Hyperparameters and configuration
+- **System**: Resource usage (GPU, memory, CPU)
+- **Files**: Logged artifacts
+
+### Local Mode
+```bash
+swanlab watch ./swanlog
+# Open browser to http://localhost:5092
+```
+
+---
+
+## Troubleshooting
+
+### SwanLab not initializing
+```bash
+# Check API key
+echo $SWANLAB_API_KEY
+
+# Verify SwanLab is installed
+pip show swanlab
+
+# Check config
+grep -A 5 "use_swanlab" your-config.yml
+```
+
+### Completions not appearing
+- Verify you're using an RLHF trainer (DPO/KTO/ORPO/GRPO)
+- Check `swanlab_log_completions: true`
+- Wait for `swanlab_completion_log_interval` steps
+- Look for "Registered SwanLab RLHF completion logging" in logs
+
+### Lark notifications not working
+- Test webhook manually: `curl -X POST "$SWANLAB_LARK_WEBHOOK_URL" ...`
+- Verify `SWANLAB_LARK_SECRET` is set correctly
+- Check bot is added to Lark group chat
+- Look for "Registered Lark notification callback" in logs
+
+### Profiling metrics not appearing
+- Verify `use_swanlab: true`
+- Check SwanLab is initialized (look for init log message)
+- Profiling metrics are under "profiling/" namespace
+- Profiling auto-enabled when SwanLab is enabled
+

+
+## Performance Notes
+
+### Overhead Comparison
+
+| Feature | Overhead per Step | Memory Usage |
+|---------|------------------|--------------|
+| Basic tracking | < 0.1% | ~10 MB |
+| Completion logging | < 0.5% | ~64 KB (buffer=128) |
+| Profiling | < 0.1% | ~1 KB |
+| **Total** | **< 0.7%** | **~10 MB** |
+
+### Best Practices
+1. Use ONE logging tool in production (disable WandB/MLflow when using SwanLab)
+2. Adjust completion log interval based on training length (100-200 steps)
+3. Keep completion buffer size reasonable (128-512)
+4. Profile critical path methods first (training_step, compute_loss)
+5. Use ProfilingConfig to throttle high-frequency operations

+# ============================================================================
+# Tips for Effective Profiling
+# ============================================================================
+
+"""
+1. Profile the critical path first:
+   - training_step, compute_loss, prediction_step
+   - These methods are called most frequently and have biggest impact
+
+2. Use throttling for high-frequency operations:
+   - Methods called 100+ times per step
+   - Use log_interval=50 or log_interval=100
+   - Reduces profiling overhead and dashboard clutter
+
+3. Filter noise with min_duration_ms:
+   - Set min_duration_ms=1.0 to skip very fast operations
+   - Focus on operations that actually take time
+
+4. Compare across runs:
+   - Run same config multiple times to check consistency
+   - Compare different optimization strategies
+   - Track profiling trends over time
+
+5. Monitor distributed training:
+   - Check for per-rank timing differences
+   - Look for stragglers (slower ranks)
+   - Identify synchronization bottlenecks
+
+6. Disable profiling in production:
+   - from axolotl.integrations.swanlab.profiling import DEFAULT_PROFILING_CONFIG
+   - DEFAULT_PROFILING_CONFIG.enabled = False
+
+7. Exception handling:
+   - Profiling is exception-safe
+   - Duration logged even if method raises
+   - Useful for debugging methods that fail intermittently

+# wandb_project:
+# use_wandb: false
+#
+# use_mlflow: false
+#
+# use_comet: false
+
+# ============================================================================
+# Expected Training Behavior
+# ============================================================================
+
+# With this configuration, you should see:
+#
+# 1. SwanLab Initialization (rank 0 only):
+#    INFO: SwanLab initialized for project: dpo-production
+#    INFO: SwanLab experiment: llama-3-dpo-full-featured-v1
+#    INFO: SwanLab mode: cloud
+#    INFO: SwanLab workspace: ml-research-team
+#
+# 2. Completion Logging (rank 0 only):
+#    INFO: Registered SwanLab RLHF completion logging callback for DPOTrainer
+#          (log_interval=100, max_buffer=256)
+#
+# 3. Lark Notifications (rank 0 only):
+#    INFO: Registered Lark notification callback with HMAC authentication
+#
+# 4. Distributed Training Detection (if multi-GPU):
+#    INFO: Distributed training detected (world_size=N)
+#    INFO: Only rank 0 will initialize SwanLab
+#    INFO: Other ranks will skip SwanLab to avoid conflicts
+#
+# 5. Training Start Notification (Lark):
+#    Your team chat receives: "Training started: llama-3-dpo-full-featured-v1"
+#
+# 6. Periodic Completion Logging:
+#    Every 100 steps, completion table is updated in SwanLab dashboard
+#
+# 7. Training Complete Notification (Lark):
+#    Your team chat receives: "Training completed: llama-3-dpo-full-featured-v1"
+#    With link to SwanLab dashboard and final metrics
+#
+# 8. SwanLab Dashboard Shows:
+#    - Training metrics (loss, learning rate, etc.)
+#    - Completion table (rlhf_completions)
+#    - Profiling metrics (profiling/Time taken: ...)
+#    - Hyperparameters and configuration
+#    - System resource usage
+
+# ============================================================================
+# Production Checklist
+# ============================================================================
+
+# Before deploying to production, verify:
+# ✅ SwanLab API key is set via environment variable (not in config)
+# ✅ Lark webhook secret is set (required for HMAC authentication)
+# ✅ Workspace is set to your team's workspace
+# ✅ Experiment name is descriptive and unique
+# ✅ Only SwanLab is enabled (other loggers disabled)
+# ✅ Completion logging buffer size is appropriate for your training duration
+# ✅ Private deployment hosts are set (if using enterprise SwanLab)
+# ✅ Test run completes successfully and shows up in SwanLab dashboard
+# ✅ Lark notifications are received in team chat
+# ✅ Profiling metrics are logged correctly
+
+# ============================================================================
+# Troubleshooting
+# ============================================================================
+
+# If SwanLab initialization fails:
+# 1. Check SWANLAB_API_KEY environment variable is set
+# 2. Verify swanlab_project is set in config
+# 3. Check swanlab_mode is valid (cloud/local/offline/disabled)
+# 4. Verify internet connectivity (for cloud mode)
+
+# If Lark notifications not received:
+# 1. Check SWANLAB_LARK_WEBHOOK_URL is set correctly
+# 2. Verify SWANLAB_LARK_SECRET matches your Lark bot settings
+# 3. Test webhook manually: curl -X POST "$SWANLAB_LARK_WEBHOOK_URL" ...
+# 4. Check training logs for "Registered Lark notification callback"
+# 5. Verify bot is added to the target Lark group chat
+
+# If completions not appearing in SwanLab:
+# 1. Verify you're using an RLHF trainer (DPO/KTO/ORPO/GRPO)
+# 2. Check swanlab_log_completions is true
+# 3. Wait for log_interval steps (default: 100)
+# 4. Check training logs for "Registered SwanLab RLHF completion logging"
+
+# If profiling metrics not appearing:
+# 1. Verify use_swanlab is true
+# 2. Check SwanLab is initialized (check logs)
+# 3. Look under "profiling/" namespace in dashboard
+# 4. Profiling may be disabled if DEFAULT_PROFILING_CONFIG.enabled = False

+# ============================================================================
+#
+# SwanLab automatically profiles trainer methods when enabled.
+# Profiling metrics appear in SwanLab dashboard under "profiling/" namespace.
+#
+# Built-in profiling:
+# - Minimal overhead (< 0.1% per step)
+# - High-precision timing (microsecond accuracy)
+# - Exception-safe (logs duration even if method fails)
+#
+# View profiling metrics in SwanLab dashboard:
+#   profiling/Time taken: AxolotlTrainer.training_step
+#   profiling/Time taken: AxolotlTrainer.compute_loss
+#   profiling/Time taken: AxolotlTrainer.prediction_step

+
+# Completion logging is disabled for non-RLHF trainers
+swanlab_log_completions: false  # Only works with DPO/KTO/ORPO/GRPO
+
+# ============================================================================
+# Optional: Compare with Multiple Runs
+# ============================================================================
+#
+# To compare profiling metrics across different configurations:
+#
+# 1. Run baseline without flash attention:
+#    swanlab_experiment_name: llama-3.2-1b-no-flash-attn
+#    flash_attention: false
+#
+# 2. Run with gradient checkpointing:
+#    swanlab_experiment_name: llama-3.2-1b-grad-checkpoint
+#    gradient_checkpointing: true
+#
+# 3. Run with both:
+#    swanlab_experiment_name: llama-3.2-1b-optimized
+#    flash_attention: true
+#    gradient_checkpointing: true
+#
+# Then compare profiling metrics in SwanLab dashboard to see performance impact
+
+# ============================================================================
+# Optional: Lark (Feishu) Team Notifications
+# ============================================================================
+#
+# Get notified when profiling experiments complete:
+
+# swanlab_lark_webhook_url: https://open.feishu.cn/open-apis/bot/v2/hook/xxxxxxxxxx
+# swanlab_lark_secret: your-webhook-secret
+
+# ============================================================================
+# Profiling Best Practices
+# ============================================================================
+#
+# 1. Run multiple epochs to see profiling trends over time
+# 2. Ignore first ~10 steps (warmup period, slower)
+# 3. Look for outliers (steps that take significantly longer)
+# 4. Compare profiling metrics before/after optimization changes
+# 5. Monitor per-rank profiling in distributed training
+#
+# Common bottlenecks to profile:
+# - training_step: Overall step time (should be consistent)
+# - compute_loss: Loss computation (scales with sequence length)
+# - prediction_step: Evaluation time (can be slow for large val sets)
+#
+# If you see inconsistent timing:
+# - Check for data loading bottlenecks
+# - Monitor GPU utilization (may be CPU-bound)
+# - Check for gradient accumulation effects
+# - Verify CUDA kernel synchronization
+
+# ============================================================================
+# Disable WandB if you're migrating from it
+# ============================================================================
