Mirelo SFX is now live on Runware

We are excited to announce that Mirelo SFX is now live on Runware — the unified AI API used by 200K+ developers and serving 10B+ requests. With one integration, builders can drop cinematic, perfectly-synced sound effects into any video they generate.

Run Mirelo SFX on Runware

Pass any video clip to Mirelo SFX and it generates cinematic, perfectly-synced sound effects — footsteps, impacts, ambience, whatever the scene needs. On Runware, that runs through the same endpoint you already use for everything else, so adding sound becomes one step in your pipeline rather than a separate vendor.

• The video is the prompt — no text descriptions, no extra setup. Mirelo SFX reads your frames and times the audio to the action.
• Real-time generation — 10 seconds of video in roughly 10 seconds of compute.
• Multiple variations — pick the take that fits the scene.

What is Runware?

Runware is one API for all AI — a single inference platform for developers building with generative models. Instead of integrating separate vendors for image, video, audio, LLM, 3D, and vision workloads, you hit one endpoint with a consistent request/response shape.

Runware delivers inference at up to 90% lower cost than other providers, with around 40% faster performance and up to 10× lower price on open-source models, and 10–40% lower pricing on closed-source models through bulk execution. The mechanism behind the numbers is the Sonic Inference Engine® — a fully custom hardware and software stack with custom servers, cooling, networking, and BIOS/kernel tuning that drives GPUs near 100% utilisation.

What you also get:

• Flexibility and control — full access to every parameter, no hidden caching that alters outputs, and support for your own LoRAs, checkpoints, and safetensors.
• Huge model library — 400K+ preloaded generative AI models, both foundation models and community fine-tunes, deployable in minutes.
• Developer ergonomics — a unified task system with sync and async modes, webhook delivery, batch processing, parameter chaining, and SDKs for common languages and frameworks.
• Enterprise readiness — SOC2 and ISO27001, SSO, organisations and permissions, 24/7 support, and a strict privacy stance: Runware never repurposes your inputs or outputs for training, and uploaded or generated content is automatically purged unless you explicitly ask for it to be stored.

A single, fast, flexible API to run essentially any generative model — and now, with Mirelo SFX, sound design for video lives there too.
