Laguna by Poolside vs Z Image Turbo: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Laguna by Poolside and Z Image Turbo — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Laguna by Poolside
Poolside
Poolside's family of open Mixture-of-Experts foundation models for agentic coding — XS.2 runs locally, M.1 reaches 72.5% on SWE-bench Verified.
Key features
- Two Model Sizes: Laguna XS.2 (33B total / 3B active) and Laguna M.1 (225B total / 23B active) target different latency and capability needs.
- Mixture-of-Experts Architecture: Routes each token through a subset of experts for efficiency at large scale.
- Local Deployment: XS.2 is small enough to run on a Mac with 36 GB of RAM via Ollama under an Apache 2.0 license.
- Strong SWE-bench Results: XS.2 hits 68.2% and M.1 reaches 72.5% on SWE-bench Verified.
- Bundled Coding Agent: Ships 'pool,' a lightweight terminal-based coding agent.
- Agent Client Protocol: Includes a dual ACP client-server used internally for agent RL training and evaluation.
Best for
- Local Agentic Coding: Running XS.2 on a laptop for private, offline code generation and editing.
- High-Capability Code Tasks: Using M.1 for harder, long-horizon software engineering work.
- Self-Hosted Deployments: Building on open weights to avoid third-party API dependencies.
- Research & Fine-Tuning: Adapting permissively licensed weights for custom coding workflows.
- Benchmarking: Evaluating agentic coding performance against SWE-bench Verified and Pro.
Z Image Turbo
Tongyi-MAI (Alibaba)
A 6B-parameter, efficient text-to-image model (Z-Image-Turbo) optimized for few-step sampling, photorealism, and English–Chinese text rendering.
Key features
- Single-Stream Diffusion Transformer (S3-DiT): Uses a scalable single-stream DiT architecture that enables unified image generation with improved efficiency compared to multi-stage pipelines.
- Few-Step Sampling (8 NFEs): Distilled to run high-quality sampling with only ~8 Number of Function Evaluations by default, enabling fast, low-latency generation suitable for interactive applications.
- 6B Parameters Optimized for 16GB VRAM: Model size and precision optimizations (bfloat16 / FP8-ready) allow practical local inference on 16 GB consumer GPUs and sub-second latency on enterprise H800-class hardware.
- Bilingual Text Rendering: Trained and conditioned to accurately render and follow prompts in both English and Chinese, improving fidelity of embedded text and multilingual layout tasks.
- Qwen 4B Conditioning & Flux VAE: Integrates the Qwen 4B text encoder for stronger prompt conditioning and a Flux autoencoder (VAE) for high-fidelity image reconstruction.
- Distillation and Instruction Adherence (DMDR): Leveraged distillation techniques (DMDR / DMD + RL) to compress model capabilities, boost instruction-following behavior, and preserve photorealistic quality.
- Low-Precision & Quantization Support: Works with bfloat16 and community FP8 quantizations, and community ports provide FP8/quantized variants for memory and speed gains.
