Experiment instantly with serverless. Scale to production with on-demand.
Go from idea to output in seconds—with just a prompt. Run the latest open models on Fireworks serverless, with no GPU setup or cold starts. Move to production with on-demand GPUs that auto-scale as you grow.
Fine Tuning
Evaluate 100× faster with Multi-LoRA
Run hundreds of fine-tuned model variants in parallel on a single deployment. Fireworks' Multi-LoRA architecture reduces iteration costs and time by 100×. Easily collaborate across teams with shared deployments in unified workspaces.
Tool Calling
Build powerful agents with tool use and memory
Build agents that reason, plan, and act reliably. Use structured tool calls (JSON, grammar mode) to trigger APIs, fetch data, and integrate business logic. Fireworks also supports memory primitives—so your models can retain and reuse context across interactions.
Model Library
Leverage 1000s of models across multiple modalities
Use preloaded, optimized models or bring your own text, vision, audio, speech, image, and video modles. Build rich, multimedia experiences, from image understanding and generation, speech transcription, and voice agents without infrastructure overhead.
