+
+## Major Achievement: Nvidia GLM-4.7 Integration ✅
+
+**Model Configuration Success:**
+- Successfully configured Nvidia GLM-4.7 model access via ZAI API
+- Switched from Hugging Face version (`huggingface/zai-org/GLM-4.7`) to free Nvidia-hosted version (`zai/glm-4.7`)
+- Added NVIDIA auth profile and model provider configuration
+- Set `nim/meta/llama-3.1-405b-instruct` as primary model fallback option
+
+**Technical Details:**
+- Added `nim:default` auth profile with API key integration
+- Configured Nvidia model provider with base URL: `https://integrate.api.nvidia.com/v1`
+- Added multiple Nvidia models to catalog: Llama 405B, Mistral 7B, Nemotron 70B, GLM-4.7
+- All models show 200k context window and zero cost (Nvidia free tier)
+
+## WhatsApp Gateway Connectivity Issues ⚠️
+
+**Recurring Problem:**
+- WhatsApp gateway experiencing frequent disconnections (status 440 errors)
+- Multiple connect/disconnect cycles throughout the session
+- Happened during model configuration changes, may be related to gateway restarts
+
+**Timeline:**
+- 23:30: Connection became unstable with rapid cycling
+- Multiple restart attempts via gateway config changes
+- Each restart triggered WhatsApp reconnection attempts
+- Status 440 errors suggest authentication or rate limiting issues
+
+## System Configuration Updates
+
+**Gateway Changes:**
+- Multiple gateway restarts during Nvidia model configuration
+- All config applies completed successfully
+- Service remained responsive despite WhatsApp issues
+- Doctor check showed huggingface auth cooldowns (resolved by model switch)
+
+**Next Steps Needed:**
+1. Investigate WhatsApp 440 error root cause
+2. Test BlueBubbles iMessage integration (user confirmed it's configured)
+3. Resume newsletter agent content extraction fixes
+4. Configure automated GitTea backups with API key
+
+## Key Learning
+
+Nvidia model integration is complex but achievable - requires:
+- Auth profile configuration
+- Model provider setup with correct API endpoint  
+- Model catalog updates
+- Proper fallback configuration
+- Gateway restarts to apply changes
+
+The free Nvidia GLM-4.7 access should reduce costs significantly while maintaining performance.
