ElevenLabs vs eratosthenes: at a glance
What is ElevenLabs?
ElevenLabs is turning voice agents into versioned software, with weekly API surface to prove it.
The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.
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().

◆ Current state
The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.
◆ Where it's heading
Two arcs run in parallel. The agent platform is acquiring the mechanics of source control, which points at teams operating many agent versions in production rather than one hand-tuned assistant. The model lines are being rebuilt one at a time and exposed API-first, with older v1 models given explicit removal dates. Dubbing is the newest line to make that jump.
◆ Prediction
The v1 deprecation pattern suggests dubbing_v1 gets a removal date next, and the branch tooling looks close to gaining an approval or promotion step given merge previews already exist.

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.
