A side-by-side comparison of Fireworks AI and Laguna by Poolside — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Fireworks AI
Fireworks AI
High-performance serverless inference and deployment platform for open-source LLMs and image models with fast inference and built-in fine-tuning.
Key features
- Blazing-Fast Inference: Optimized serverless runtime for low-latency inference of open-source LLMs and image models, designed to reduce response times for production workloads.
- Serverless Model Hosting: Host and run models via a cloud API without managing servers, autoscaling, or instance provisioning — simplifying deployment and operations.
- Fine-Tuning Support: Built-in workflows and tooling to fine-tune open-source models and deploy the tuned checkpoints with no additional deployment cost (per official claim).
- Hugging Face Integration: Supported as an Inference Provider on the Hugging Face Hub, enabling serverless inference directly from model pages and seamless hub interoperability.
- Developer SDKs and Plugins: Client libraries, third-party plugins (e.g., llm-fireworks), and example repositories to integrate Fireworks into applications and ML pipelines quickly.
- Cookbook & Examples: Public cookbook, Jupyter notebooks, and showcase projects that provide recipes for building, deploying, RAG systems, function-calling, and agentic workflows.
- Cloud API & Platform Tools: REST/HTTP API and developer tooling for model lifecycle operations — upload, manage, and invoke models programmatically.
- Cloud API for model hosting and inference (no infrastructure management)
- Serverless, low-latency inference optimized for generative models
- Support for open-source LLMs and image models
- Fine-tune and deploy models (advertised at no additional cost)
- Hugging Face Inference Provider integration (serverless inference on HF Hub)
- SDKs/plugins and community integrations (e.g., llm-fireworks plugin)
- Cookbook repository with recipes, Jupyter notebooks, and sample apps
- Docker and local development support and examples
- Showcase projects and example workflows (RAG, function-calling, agentic systems)
Best for
- Low-latency production inference: Serve open-source LLMs and image models in production apps that require fast, serverless responses without managing infrastructure.
- Custom model fine-tuning and deployment: Fine-tune foundation models on proprietary data and deploy the tuned model through Fireworks’ hosting and API.
- Hugging Face model pages inference: Run serverless inference directly on model hub pages by using Fireworks as a supported inference provider.
- Prototype-to-production workflows: Use the cookbook examples and SDKs to prototype generative applications, then scale them to production with managed hosting and autoscaling.
- RAG and agentic systems: Build retrieval-augmented generation pipelines and agentic systems using provided recipes, function-calling examples, and integration resources.
- Developer integrations and plugins: Embed model inference into applications via the Fireworks cloud API or community plugins (e.g., llm-fireworks) for quick application integration.
- Production-grade model inference for apps and APIs requiring low-latency generative outputs
- Fine-tuning open-source LLMs and deploying custom models without managing servers
- Image generation and multimodal model hosting
- Retrieval-augmented generation (RAG) pipelines and function-calling workflows
- Rapid prototyping using provided cookbooks and Jupyter notebooks
- Integrating model inference into existing platforms via API or Hugging Face provider
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.
