TITAN-MoE: Topology-Aware and Predictive Expert Orchestration for Distributed Mixture-of-Experts Inference on Apple Silicon

A Measured Systems Study on a Heterogeneous Mac Cluster

Simon-Pierre Boucher · UQO Working Papers · November 2026 · v0.1

Sparse mixture-of-experts (MoE) language models touch only a few experts per token, so a model whose weights exceed a machine's memory can still be served if the right experts are in the right place at the right time. This preliminary working paper reports the design, implementation and measurement of TITAN-MoE, an…

PRISME: Intervention-Supervised Sparse Workspace Editing for Small Language Models

Design, controlled evaluation, and negative and positive evidence at the 100M-parameter scale

Simon-Pierre Boucher · UQO Working Papers · October 2026 · v1.0

PRISME augments a frozen causal decoder with a read-only source bank, an ephemeral sixteen-slot latent workspace re-created at every position, a shared sparse editor that rewrites one or two slots per action, a value controller trained on counterfactual intervention gains measured by executing paired edit/no-edit…

Beyond Text: Cache Compression and Knowledge Transfer in Multi-Agent Systems

A Reproducible Study of Fidelity, Communication Cost, and Repeated Handoffs

Simon-Pierre Boucher · UQO Working Papers · October 2026 · v1.0

Agents built on language models hand information to one another as text, summaries, structured evidence, shared-memory references or, when they share a checkpoint, attention state (the KV cache). This paper asks under which task, model, cache, network and reuse conditions each representation preserves task-relevant…
