Term Meaning
Ember OtherU's inference engine for DeepSeek-V4-Flash on AMD Strix Halo. See Ember.
Hermes Agent Software that connects a model to conversations, tools, scheduling, and memory integrations.
Hindsight A persistent memory service used by Hermes. See Hindsight Memory.
Memory bank A named grouping of memories in Hindsight. Grouping alone does not establish access control.
KV cache Model attention state reused to avoid processing an eligible prompt prefix again. It is distinct from stored conversation history.
Prefill Processing input tokens before generating a response.
Decode Generating response tokens after prompt processing.
Time to first token Elapsed time before the first output token, including relevant queueing and prompt-processing work.
DSpark A draft model used in Ember's speculative-decoding path.
Speculative decoding A smaller model proposes tokens that the target model verifies, potentially reducing the cost of generation.
Acceptance rate The fraction of draft tokens accepted during verification; it varies by model pair and workload.
Quantization Representing model weights at reduced precision to reduce storage and memory use.
bpw Bits per weight, a measure of effective model-weight storage cost.
imatrix An importance matrix collected from representative inputs to guide quantization.
Affine fp2 OtherU's custom Q2_0_ROCMFP2 format. See Quantization Pipeline.
Abliteration A model-weight edit intended to reduce refusal behavior. Its effect on other capabilities must be evaluated.
MoE Mixture of Experts: a model architecture that activates selected expert networks for each token.
GGUF A file format for model tensors and metadata. Runtime support depends on the architecture and tensor encodings inside it.
Strix Halo The AMD Ryzen AI Max platform used by the reference inference host.
gfx1151 The GPU architecture identifier targeted by Ember's Strix Halo backend.
Unified memory Physical memory shared by CPU and GPU, subject to platform limits and competing allocations.
Hardware KVM A device that captures display output and delivers keyboard and mouse input to another computer.
Loopback A network interface reachable from the same network namespace, commonly addressed as 127.0.0.1.
Air gap Network separation from external systems. A local model does not by itself create an air-gapped deployment.
