Laguna by Poolside vs Mistral AI: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Laguna by Poolside and Mistral AI — 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.
Mistral AI
Mistral AI
Enterprise AI platform and creator of high-performance open models for fine-tuning, deploying assistants, agents, and multimodal applications.
Key features

- Instruction Fine-Tuning & Tool Calling: Provides instruct-tuned variants and support for function/tool calling to enable structured interaction patterns and integrable tool-based workflows.
- Enterprise Deployment Platform: Offers tooling and platform services to customize, fine-tune, host, and deploy AI assistants and autonomous agents for enterprise use cases with production-ready integrations.
- Multimodal Capabilities: Supports building multimodal applications (vision+text, OCR, etc.) by providing models and integration examples for mixed-input scenarios.
- SDKs & Inference Libraries: Maintains official client libraries and inference/preprocessing repos (Python, JS/TS) on GitHub to streamline integration, preprocessing, and serving of models.
- Permissive Licensing & Distribution: Publishes many models under permissive licenses (e.g., Apache-2.0) with clear distribution terms, enabling commercial and research use subject to the license.
- Collaborative Model Engineering: Releases jointly developed or co-trained models (e.g., collaborations with NVIDIA) and documents model cards and technical details on Hugging Face.
- Platform for customizing, fine-tuning, and deploying LLMs and multimodal models
- Support for building and deploying AI assistants and autonomous agents
- Open-source and commercial model offerings (e.g., Mistral 7B, Mixtral variants, Mistral-Nemo-Instruct)
- Models and model cards hosted on Hugging Face with accompanying metadata and deployment examples
- Function-calling and tool-calling support (includes tool-call IDs and examples in docs)
- Compatibility with common ML frameworks and ecosystem tools (Transformers integration referenced)
- Community SDKs and integrations (example: Ruby gem, Next.js agent builders, TypeScript projects)
- Licensing and distribution options (Apache-2.0 referenced for some models)
- Support for Retrieval-Augmented Generation (RAG), classification, coding, OCR demos, and chatbots as illustrated by community projects
Best for
- Enterprise Assistants: Build and deploy domain-tuned conversational assistants for customer support, sales, or internal knowledge bases using fine-tuning and the deployment platform.
- Autonomous Agents: Create multi-step autonomous agents that call external tools and services using function/tool calling and agent orchestration capabilities.
- Domain Fine-Tuning: Fine-tune open Mistral models on internal datasets (legal, medical, technical) to improve accuracy and compliance for vertical-specific tasks.
- Retrieval-Augmented Generation (RAG): Combine Mistral models with retrieval systems to answer queries from proprietary documents, knowledge bases, or product catalogs.
- Multimodal Applications: Implement OCR, document understanding, or vision+language features by leveraging multimodal model variants and integration examples.
- Product Integration & Inference: Integrate inference SDKs into web or backend services (via official Python/JS clients) to power features like code generation, summarization, and classification.
- Enterprise assistants and conversational agents for customer support and internal knowledge
- Autonomous agent workflows orchestrating tools via function/tool calls
