## Outstanding Items (Non-Blocking)
|
|
|
|
### Phase 2 Enhancements (Optional)
|
|
1. Gradient checkpointing for TFT-225 QAT (1-2 weeks)
|
|
2. OOM recovery integration into training loop (8 hours)
|
|
3. QAT support for MAMBA-2, DQN, PPO (2-3 weeks)
|
|
4. PPO shared trunk architecture (21-31% memory reduction, 6-10 hours)
|
|
|
|
### Known Limitations
|
|
- Gradient checkpointing: CLI flag exists but implementation incomplete
|
|
- OOM recovery: AutoBatchSizer exists but no retry loop
|
|
- Multi-model QAT: Only TFT supported currently
|
|

|
|
- ✅ Docker services healthy
|
|
- ✅ Region targeting fixed (EUR-IS-1)
|
|
|
|
**Recommendation**: **DEPLOY IMMEDIATELY**
|
|
|
|
### QAT Deployment Options
|
|
|
|
**Option 1: TFT-90 QAT (Ready Now)**
|
|

|
|
- ✅ All tests passing (30/30)
|
|
- ✅ No gradient checkpointing needed
|
|
- ⏱️ Timeline: Can deploy today
|
|
|
|
**Option 2: TFT-225 QAT (Phase 2)**
|
|
- ⚠️ Requires gradient checkpointing implementation
|

|
|
- ⏱️ Timeline: 2-3 weeks total
|
|
|
|
