Scores and ranks appear only where published evidence can be displayed. The table keeps the score, weight, cohort, and evidence state together.

Coverage detailsHow much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

Benchmark ledger
Coding opens by default. The marker compares each value with the best source-verified result in the catalog; provisional leaders do not set the reference. Expand the remaining categories for every published row.

All 5 rowsLineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Laguna XS 2.1, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Laguna XS 2.1 is a open weight model with a 262K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Poolside publishes the 33B-total, 3B-active MoE weights under OpenMDW-1.1 on Hugging Face with a 262,144-token context window and native interleaved thinking, and serves it through the Poolside API and OpenRouter (free for a limited time at launch).
Official exact-value snapshot from the Laguna XS 2.1 Hugging Face model card and July 2, 2026 launch post. BenchLM maps SWE-bench Verified, SWE-bench Multilingual, SWE-Bench Pro (public dataset), and Terminal-Bench 2.0 onto their existing lanes; the Terminal-Bench 2.0 value is provider-run and is blocklisted from the weighted lane. Competitor columns in Poolside’s table are context only and are not written onto other models.
Laguna XS 2.1 sits in the Laguna family with Laguna S 2.1, Laguna M.1, Laguna XS.2. Its explicit predecessor is Laguna XS.2. 5 of 766 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated October 25, 2026. Runtime fields remain blank until a sourced snapshot exists.
Deployment options
Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.
Where to run Laguna XS 2.1 by API
OpenRouter is the one host we track that publishes a per-token price for it. Prices read from each host’s own pages on October 20, 2026.
| Host | Input /1M | Output /1M | Cached /1M | Context |
|---|---|---|---|---|
| OpenRouter | $0.06 | $0.12 | $0.03 | 262K |
Published weights are available, but BenchLM does not yet have a sourced parameter and VRAM profile for this exact model. Hardware cost estimates stay unavailable until that sizing record is complete.
Estimate VRAM from known parametersQuestions
How does Laguna XS 2.1 perform overall in AI benchmarks?
Laguna XS 2.1 has 5 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is Laguna XS 2.1 good for coding and programming?
Laguna XS 2.1 has source-displayable benchmark coverage for coding and programming, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is Laguna XS 2.1 good for agentic tool use and computer tasks?
Laguna XS 2.1 has source-displayable benchmark coverage for agentic tool use and computer tasks, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is Laguna XS 2.1 open source?
Laguna XS 2.1 is an open-weight model from Poolside. Its weights can be downloaded for local or hosted deployment, subject to the published license. Open weight does not automatically mean open source: training data and training code may remain private, and commercial restrictions can still apply.
Which sibling models are related to Laguna XS 2.1?
Laguna XS 2.1 belongs to the Laguna family. Related tracked variants include Laguna S 2.1, Laguna M.1, Laguna XS.2. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Laguna XS 2.1 have full benchmark coverage on BenchLM?
No. Laguna XS 2.1 currently has 5 source-displayable rows. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Laguna XS 2.1?
Laguna XS 2.1 has a documented context window of 262K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
