# Laguna S 2.1 model profile

Laguna S 2.1 is a Poolside model profile with a 1,048,576-token context window. The dated catalog snapshot records text modalities and interfaces for prompt caching, reasoning controls, text generation, tool calling.

Laguna S 2.1 is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.

Laguna S 2.1 accepts text and returns text. The snapshot records prompt caching, reasoning controls, text generation, and tool calling as capabilities or interfaces.

The dated reference snapshot lists $0.09 input and $0.18 output per million tokens. Cached input is $0.009 per million tokens.

No comparable third-party benchmark value is present in the 2026-08-12 snapshot. Missing values are not estimated.

Laguna S 2.1 ranked #76 in the cited trailing-7-day third-party catalog usage dataset as of 2026-08-12. Observed within the cited trailing-7-day third-party catalog usage dataset; this is not global AI market share.

Profile data was reviewed for the 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.
