Beveridge: decisions, not essays

Beveridge is a family of open-weight System One decision models. Give it a document and typed questions (yes/no, one of your options, or a level on your scale) and it returns an answer with a calibrated probability for every option, without generating text, on your own machines. Beveridge-Large-C runs on a laptop CPU; Beveridge-Pro-C brings more knowledge on a GPU; the new Beveridge-Pro-C-Web also picks every step of a browser agent. Released under Apache-2.0, free for commercial use.

Self-evolving procedural graphs: LLM agents are moving from "memory" to "topology", and where current architectures fail in production

Agents structure procedural knowledge into explicit graphs of (procedure, relation, procedure) triplets, and an offline "LLM refiner" mutates the graph when they fail. The benchmark results are strong, but deterministic offline feedback loops break down in enterprise deployments.

Read the digest
  1. The offline latency penalty. Runtime environments don't wait for an offline optimisation epoch: if an API contract changes or a service returns a new error code, a static procedural graph cannot repair its topology on the fly.
  2. Node localisation collapse. Mapping noisy real-world feedback to discrete graph nodes assumes states fit predefined schemas; on edge cases the agent cannot identify its active node and falls back to unconstrained generation or repeats invalid steps.
  3. Combinatorial graph bloat. Handling thousands of edge cases deterministically makes explicit graphs explode in size, congesting the context window and slowing retrieval.

Failure mode, automated logistics agent. Path: Verify order → Check warehouse API → Process refund. During a peak sale the shipping API throws an unmapped error (ERR_SYNC_TIMEOUT_503); the state cannot be localised, the graph offers no guidance, and the system takes an unmapped path (an unauthorised refund, or a crash) until an engineer runs an offline evolution pass.

Where multi-agent design must go next: dynamic runtime node spawning (transient, conditional subgraphs during execution); hybrid latent–explicit memory (explicit graphs for core logic, latent state for edge cases); real-time local graph repair instead of batch evolution.
