Poolside releases Laguna S 2.1, an agentic coding model with 118B total parameters and 8B activated parameters per token that launched in under nine weeks. It supports a context window of up to 1M tokens, scores 70.2% on Terminal-Bench 2.1, and has a knowledge cutoff date in November 2025. Full evaluation trajectories are available for every trial in the final evaluation set.written, reviewed, cited
- Laguna S 2.1 scored 40.4% in our agent harness, pool, not mini-swe-agent which DeepSWE's leaderboard uses.

Poolside AI releases Laguna XS.2 and Laguna M.1, agentic coding models now served at 256K context lengths with stronger scores on SWE-bench Verified and Terminal-Bench 2.0. Laguna XS.2 is a 33B total parameter MoE with 3B activated parameters, trained on 30T tokens using NVIDIA Hopper GPUs, reaching 44.5% on SWE-Bench Pro and 30.1% on Terminal-Bench 2.0. The model is available under an Apache 2.0 license and free via API and OpenRouter for a limited time.written, reviewed, cited
- Benchmarking used a maximum of 500 steps and sandboxed execution using 8 GB RAM/2 CPUs for most tasks.
- The Laguna series uses approx. 4.4T+ synthetic tokens to complement natural web data throughout pre-training.
- Laguna XS.2 is supported in NVIDIA TensorRT-LLM on Day 1 with an NVFP4 version for Blackwell architecture.

Laguna XS 2.1 33B runs on a single RTX 3090 with speculative decoding to achieve 296 tok/s peak speed and maintain 152 tok/s at 256K context. The system uses KVFlash paging with an 8K pool and ring caches to handle contexts that do not physically fit in 24 GB of VRAM while keeping output quality lossless. Prefill processes 256K tokens in 67 seconds at ~3,500 tok/s using a Qwen3-0.6B drafter for scoring KV chunks.written, reviewed, cited
- The full KV cache for 256K tokens requires approximately 20 GB, exceeding the 24 GB VRAM limit of the RTX 3090.
- Sliding-window layers skip the pager entirely by attending a 2K position ring instead of the whole KVFlash pool.
- The prefill drafter compresses prompts and scores KV chunk residency, falling back to recency-only LRU without it.

A new benchmark harness evaluates Laguna S 2.1 quantizations on Apple Silicon, finding that pipenetwork/Laguna-S-2.1-MLX-2bit leads on the M5 Max. It achieved a perfect score passing all 38 assertions and 63.86 tok/s generation throughput while using 39.31 GB peak memory. The model reached 68.49 tok/s in the fixed 256-token decode on macOS 27.0 with MLX 0.32.0.written, reviewed, cited
- The official NVFP4 MLX build was functional but much slower in this runtime.
- Vcruz's IQ1_S lowers the hardware floor to a 22.13 GiB payload but failed every generation assertion and 17 of 19 agentic assertions.

Nanbeige4.2-3B and Laguna S 2.1 target agentic workloads at different scales. Nanbeige4.2-3B uses a Looped Transformer with 22 physical decoder layers executed twice to achieve 44 layer executions without storing 44 independent layers, fitting on a 16GB GPU but consuming roughly 44 GiB of KV-cache memory at 256K context. Laguna S 2.1 is a 118-billion-parameter Mixture-of-Experts model activating approximately 8 billion parameters per token, featuring 48 transformer layers and 256 routed experts, requiring vLLM 0.25.0 and a 96 GB GPU to exploit its 256K context length.written, reviewed, cited
- Nanbeige's default configuration does not enable loop-level KV sharing, potentially requiring separate key/value entries for each pass.
- Retaining reasoning traces in conversation history risks reaching the model's maximum context length on the very next turn.

This American (San Francisco) model, Laguna S 2.1:118B-a9B, outperforms Qwen3.5:122B-a10B and Sonnet in current benchmarking tests. It demonstrates better personality and natural creativity when designing UIs. Benchmarks need to include a minimum of hardware requirements, which are currently missing.written, reviewed, cited
