   Fireworks documents API/CLI (firectl) access to essentially every major capability — inference, fine-tuning, LoRA deployment, model upload, autoscaling, batch inference, benchmarking — implying an API-first architecture where the UI is largely a thin layer over these APIs. However, there is no explicit statement or audit confirming full UI/API feature parity, and no evidence addressing whether any UI-only conveniences (e.g., dashboard analytics, billing, team management) lack API equivalents. Missing for 10: an explicit parity statement or audit, evidence covering account/billing/UI-only features, and independent confirmation that no UI feature is API-inaccessible.

   Fireworks AI~partialclaimed5/10

   Fireworks documents tool/function calling as a supported feature (docs-2) and structured JSON-schema outputs (docs-19), which underpin agent tool-use loops, but there is no documentation or evidence specifically addressing parallel tool calls, multi-step tool-use reliability, or fidelity benchmarks against OpenAI-style tool calling on open models. missing for 10: explicit parallel/multi-step tool-calling documentation, reliability/fidelity benchmarks, independent hands-on validation of agent-loop tool use.
