Orchestra vs Fireworks

Fireworks
GPUs, inference, and training tools for machine learning teams working on open models.1,2
Orchestra
Measures every workflow against your definition of success, improves each one, and trains models your team owns.9

Side by side

Orchestra and Fireworks compared on 4 dimensions
Primary jobFireworksInference and training for open models, on serverless APIs or GPUs billed by the second. Built for teams that train and serve models themselves.1,2,5OrchestraEvaluates production work, improves the prompts and routes behind it, and trains specialist models your team owns.9
RoutingFireworksFireRouter routes coding-agent turns between Fireworks open models and Claude Opus or GPT on your own credentials.6OrchestraRoutes each workflow to the model that measures best on your own work, whether or not it runs on Fireworks.
TrainingFireworksManaged SFT, DPO, and ORPO with LoRA or full-parameter options. Teams can also write their own loss, trainer, and RL loop on Fireworks GPUs.3,1OrchestraRepairs prompts, schemas, parsers, and tool contracts first. For a recurring task, trains a specialist from accepted traces and expert corrections.9

Fireworks is built for machine learning teams.Orchestra does the measurement for you.

Fireworks gives technical teams the GPUs and tools to train models by hand. Deciding which model is right for each workflow is still your team's job.

What Fireworks gives your team

  • GPUs billed by the second, plus serverless inference for open models.5,1
  • Training tools, including your own loss, trainer, and RL loop.1,3
  • FireRouter, a router for coding agents across a few models.6
  • Eval Protocol, a framework for writing your own evals.7

What Orchestra does for you

  • Builds task-specific benchmarks, such as whether the model updated the right record or followed your policy, and compares models on the same held-out work.9
  • Compares candidate models on held-out work for quality, response time, and cost.9
  • Routes to any provider, on or off Fireworks.
  • Trains specialist models from accepted traces and expert corrections.9

Where Orchestra is different

  1. Measurement done for you

    With Fireworks, your team writes and maintains the evals. Orchestra builds the benchmarks for each workflow and runs the comparison for you.7,9

  2. Every model, not one platform's

    FireRouter chooses between Fireworks open models and Claude Opus or GPT for coding turns. Orchestra compares and routes across any model or provider.6

  3. Training decided by results

    Orchestra repairs prompts, schemas, parsers, and tool contracts first. For a recurring task, it trains a specialist from accepted traces and expert corrections.9

When each approach makes sense

  • Fireworks makes sense when

    • You have a machine learning or research team that trains models by hand.1
    • You want GPUs by the second and your own RL loop on hosted hardware.5,1
    • You already run other GPU platforms alongside it, such as Baseten or Together AI.

  • Orchestra makes sense when

    • You want to optimize and measure across every model, not one platform's.
    • You want the measurement done for you.
    • You need to route to any provider, on or off Fireworks.
    • You want to improve prompts and routes, then train a specialist you own.9

    Teaching a CRM agent to finish the job

    75.5%

    lower model cost than Sonnet 4.6

    Model spend per seven-task AutomationBench CRM run: $0.27 for Qwen 3.6 Plus with a revised prompt, $1.12 for Sonnet 4.6. The revised prompt also scored 13.1% higher on mean task score.
