🔧 Technical Details
Parallel Scan Algorithm
# Before: Pseudo-parallel (actually sequential)
for block_idx in range(num_blocks):
block_states = self._block_scan(...)
# After: True parallel computation
log_A = torch.log(A.clamp(min=1e-20))
cumsum_log_A = torch.cumsum(log_A, dim=1) # Parallel
prefix_A = torch.exp(cumsum_log_A) # ParallelCache Management
from minimamba import InferenceParams
# Initialize cache
inference_params = InferenceParams()
# Use cache for efficient generation
output = model(input_ids, inference_params)
# Monitor cache usage
cache_info = model.get_cache_info(inference_params)Modular Configuration
# Base configuration (no NLP coupling)
base_config = BaseMambaConfig(d_model=512, n_layer=12)
# Specialized configurations
lm_config = MambaLMConfig(vocab_size=32000, **base_config)
class_config = MambaClassificationConfig(num_labels=3, **base_config)📊 Performance Benchmarks

model = Mamba(config) # Now uses optimized architecture automaticallyFull Migration (Best Performance)
# Use new specialized models
from minimamba import MambaForCausalLM, MambaLMConfig
config = MambaLMConfig(d_model=512, n_layer=12, vocab_size=32000)
model = MambaForCausalLM(config)
# Use advanced generation
generated = model.generate(
input_ids,
max_new_tokens=50,
temperature=0.8,
use_cache=True
