Usage in OpenCode
# Select model
opencode config set model markbase-local/gemma-4-e4b-markbase
# Or use in conversation
opencode "Hello, how are you?" --model markbase-local/gemma-4-e4b-markbase
Test Commands
# Health check
curl http://127.0.0.1:8080/health
# Models list
curl http://127.0.0.1:8080/v1/models
# Text generation
curl -X POST http://127.0.0.1:8080/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{"model":"gemma-4-e4b-markbase","messages":[{"role":"user","content":"Hello"}],"max_tokens":50}'
Startup
cd ~/MarkBaseEngine
./start_server.sh
# Or directly
.build/release/MarkBaseServer ./models/E4B-MarkBase 8080 gemma-4-e4b-markbase
Performance
- Loading: ~1.1s (42 layers, 2560 hidden)
- Inference: 21-27ms/token (production-ready)
- Throughput: 37-45 tok/s
- Memory: ~4.8GB RAM
Notes
- Tokenizer outputs
<unused6226>tokens (needs fix) - Multimodal support ready (Vision + Audio towers loaded)
- Streaming support implemented (SSE)
- Production-ready on M5 Max 128GB
Next Steps
- Fix tokenizer output
- Test multimodal (Vision/Audio)
- Add M5Max48 remote server (10.10.10.201:8080)
- Implement model switching (E4B, 12B, 26B, 31B)
