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 Neon?
Neon positions itself as the default Postgres for AI agents — distribution moves outpace database moves.
Neon is shipping at high cadence with two clear threads. The database itself is keeping up (Postgres 18 GA, 2FA, spend controls, free-tier collaboration), while the more strategic energy is going into being where AI agents already are — Codex plugin directory, Stripe Projects, neonctl init now configuring MCP for fourteen AI assistants. The product is no longer trying to win on database features alone; it's winning on being a one-command provision step for any agent stack.

◆ 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.
Neon
4.6INFRA · APIS
Neon positions itself as the default Postgres for AI agents — distribution moves outpace database moves.
◆ Current state
Neon is shipping at high cadence with two clear threads. The database itself is keeping up (Postgres 18 GA, 2FA, spend controls, free-tier collaboration), while the more strategic energy is going into being where AI agents already are — Codex plugin directory, Stripe Projects, neonctl init now configuring MCP for fourteen AI assistants. The product is no longer trying to win on database features alone; it's winning on being a one-command provision step for any agent stack.
◆ Where it's heading
The Stripe Projects integration and Codex plugin are the same idea executed twice: meet developers and agents where their workflow starts, not where Neon's console lives. The MCP-everywhere push reinforces that. Database-side moves (Postgres 18, spend limits, 2FA) are the cost of being taken seriously by enterprise buyers but aren't the strategic lever — the lever is platform presence in agent-first developer tooling.
◆ Prediction
Expect Neon to keep multiplying these distribution surfaces — likely a Vercel-style deeper integration with another major AI IDE, plus more agent-friendly primitives (per-request branches as a first-class agent concept, fine-grained usage budgets per branch) tuned for autonomous workloads.
