Dust vs eratosthenes: at a glance
What is Dust?
Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
◆ Current state
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.
◆ Where it's heading
The product is converging on agents-in-the-enterprise via MCP, with multi-model routing as table stakes. MCP V2 migrations and image returns from MCP tools point to the protocol becoming Dust's integration backbone. The model-refresh cadence — three vendors in 48 hours — suggests model routing is now a core competency, not a feature.
◆ Prediction
Expect more MCP V2 connector migrations and richer MCP return types beyond images. The voice-first mobile input bar likely precedes a deeper voice-mode agent surface.
eratosthenes
2.5INFRA · APIS
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.
