    Why switch from Fireworks AI

    Runs popular open models on its own LPU chips for very fast token output, through an OpenAI-compatible API.

    Pros

    • Very high output speed on its own inference hardware
    • OpenAI-compatible API, so switching takes a base URL change
    • Free tier for prototyping, pay-as-you-go above it
    • Batch API at half the normal token price

    Cons

    • Curated model list, far smaller than Replicate or Together AI
    • Some models are enterprise-only with sales pricing
    • Free tier rate limits are tight for real workloads

    score / 100

    Why switch from Fireworks AI

    Pick from many hosts, including Fireworks itself, and fall back between them with one key.

    Pros

    • Hundreds of models behind one OpenAI-compatible API
    • Automatic fallback to other providers when one is down
    • Free models available for testing

    Cons

    • A fee is added on every credit purchase
    • Hosted only, so it can't be self-hosted
    • Free tier is capped at 50 requests per day
