What is Baseten?

Baseten ends the free launch of elephant-1 and mammoth-1 and adds per-replica metrics.

Baseten's newest entries are commercial and operational. The elephant-1 and mammoth-1 classification models, launched free on October 21, moved to paid usage on Model APIs from October 27, and workspaces can now compare CPU, GPU and memory per replica to find outliers that aggregate graphs hide. The week before was mostly security: API keys unused for 30 days are revoked automatically, auth errors switch from 403 to 401 on October 28, and users were told to upgrade CLIs after the eMudhra CA compromise.

What is Character.AI?

Character.AI is becoming an interactive entertainment studio, absorbing comics and original series into its Character ecosystem.

Character.AI has made a clear pivot from conversational AI chatbot platform to interactive entertainment. The product now spans Microdramas (studio-made vertical series), comics, interactive Books, and Lorebook for creator worldbuilding — each format using Character interaction as its core primitive rather than as an add-on. Safety remains a persistent constraint: under-18 open-ended chat restrictions stay in place and public safety updates continue, reflecting ongoing legal scrutiny that shapes product decisions.

5.0

Baseten ends the free launch of elephant-1 and mammoth-1 and adds per-replica metrics.

◆ Current state

Baseten's newest entries are commercial and operational. The elephant-1 and mammoth-1 classification models, launched free on October 21, moved to paid usage on Model APIs from October 27, and workspaces can now compare CPU, GPU and memory per replica to find outliers that aggregate graphs hide. The week before was mostly security: API keys unused for 30 days are revoked automatically, auth errors switch from 403 to 401 on October 28, and users were told to upgrade CLIs after the eMudhra CA compromise.

◆ Where it's heading

Baseten keeps adding models to Model APIs on a free-then-paid launch pattern, while building out observability for dedicated deployments: GPU temperature and utilization a week ago, per-replica breakdowns now. The security tightening of late October appears to have settled into defaults.

◆ Prediction

Expect further Model API additions following the same free launch window before paid usage, and more per-replica or per-worker debugging tools for dedicated deployments.

Character.AI is becoming an interactive entertainment studio, absorbing comics and original series into its Character ecosystem.

◆ Current state

Character.AI has made a clear pivot from conversational AI chatbot platform to interactive entertainment. The product now spans Microdramas (studio-made vertical series), comics, interactive Books, and Lorebook for creator worldbuilding — each format using Character interaction as its core primitive rather than as an add-on. Safety remains a persistent constraint: under-18 open-ended chat restrictions stay in place and public safety updates continue, reflecting ongoing legal scrutiny that shapes product decisions.

◆ Where it's heading

Each new media format (comics, series, books) generates IP and Character richness that feeds back into the ecosystem. The creator layer — Lorebook, discovery features, creator bundles — is being built in parallel to enable user-generated Characters to power these formats rather than relying solely on studio output. The arc is a content platform where Characters are the connective tissue across media types.

◆ Prediction

The next format addition will likely be audio or IP licensing deals bringing established fictional universes onto the platform, following the pattern of absorbing existing media forms into the Character interaction layer.
