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().

What is Replicate?

Replicate is courting AI coding assistants — agent skills, MCP auto-discovery, llms.txt all in the same window.

Replicate is shipping for an agent-first audience. Recent releases include published Agent Skills (markdown instruction files coding assistants can load), MCP server auto-discovery via /.well-known/mcp/server.json, automatic llms.txt generation for documentation, model-level fallback support (Nano Banana Pro auto-routes to ByteDance Seedream 5.0 lite when Google's API is at capacity), and approximate cost display on predictions and trainings.

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.

2.9

Replicate is courting AI coding assistants — agent skills, MCP auto-discovery, llms.txt all in the same window.

◆ Current state

Replicate is shipping for an agent-first audience. Recent releases include published Agent Skills (markdown instruction files coding assistants can load), MCP server auto-discovery via /.well-known/mcp/server.json, automatic llms.txt generation for documentation, model-level fallback support (Nano Banana Pro auto-routes to ByteDance Seedream 5.0 lite when Google's API is at capacity), and approximate cost display on predictions and trainings.

◆ Where it's heading

Replicate is making itself the obvious choice for AI coding assistants and agents that need to run models. Three of the recent releases (agent skills, MCP auto-discovery, llms.txt) explicitly target machine consumers, not human developers. The fallback-model release is a different but related move: making model APIs production-grade by routing around capacity issues automatically — the kind of reliability work that separates a hobbyist platform from a real inference layer.

◆ Prediction

Expect more skills covering specific model categories (audio, video, fine-tuning), broader MCP-tool surface, and probably native fallback chains for additional flagship image and video models. Cost-attribution work (per-prediction visibility) is likely to keep deepening as agent-driven usage scales.
