Smartbloom 1.1 Advanced is a speculative AI model designed to push the boundaries of scale and capability:
- 65,536 layers for unprecedented depth.
- 16,384 experts in a hierarchical MoE structure for extreme specialization.
- Dynamic multi-query attention for efficient and powerful sequence processing.
- 16,384-token context window for long-range dependencies.
- Advanced training with Adafactor, cosine restarts, and extreme parallelism.
- Experimental features like sparsity, quantization, and speculative decoding for future-proofing.

This configuration assumes a futuristic compute infrastructure capable of handling
674 trillion parameters, likely requiring millions of GPUs/TPUs or novel hardware.
