In the news
Poolside releases Laguna S 2.1, a 118B-parameter open-weight model with a 1M-token context
Poolside introduced Laguna S 2.1 on July 21, 2026, a Mixture-of-Experts model with 118B total parameters and 8B activated per token that the model card says is designed for agentic coding and long-horizon work. Poolside describes it as a scale-up of the Laguna XS family, and the model card lists a 1,048,576-token context window. The weights are on Hugging Face under the OpenMDW-1.1 license, with FP8, NVFP4, INT4, and GGUF variants and a DFlash draft model for speculative decoding. USASI has not tested this model.
Poolside releases Laguna XS 2.1, a 33B-parameter open-weight coding model, under OpenMDW-1.1
Poolside introduced Laguna XS 2.1 on July 2, 2026, describing it as a Mixture-of-Experts model with 33B total parameters and 3B activated per token. The model card calls it an upgraded version of Laguna XS.2, designed for agentic coding and long-horizon work on a local machine. Poolside licenses the weights under OpenMDW-1.1 and publishes them on Hugging Face in BF16, FP8, NVFP4, and INT4 formats; the model is also offered through Poolside's API and OpenRouter. USASI has not tested this model.
U.S. eligibility
Eligible · basis: U.S. headquarters
Assessment of a company with a significant presence in France. Poolside's July 2026 press release states that it is headquartered in San Francisco. Its current Terms of Use name the contracting entity as Poolside, Inc., a Delaware corporation with a San Francisco address, governed by California law. Earlier reporting described the company as having moved its headquarters to Paris (French Tech Journal, November 2023) and as Paris-based after relocating to France (Fortune, September 2024), and the French business registry lists an active Paris-registered company, POOLSIDE AI (SAS), created in July 2023. The most recent official statements place the headquarters in San Francisco, so the U.S.-headquarters basis applies. Two points are not documented: how the U.S. and French entities are related, and whether the San Francisco address in the legal documents, a private mailbox, is also a staffed office. Re-check if Poolside's stated headquarters changes.124675
