## How they compare

Runware and Subconscious produce different outputs. Runware prices media per generation, with images from fractions of a cent and video per second, such as Seedance 2.5 at about $0.10 a second at 480p, across 300+ priced models behind one task schema. It hosts text too, but LLM hosting is a side line next to media. Subconscious is LLM inference for long-horizon agents. It serves GLM 5.3 and DeepSeek V4.1 Flash, prunes the KV cache as a trace grows, and bills tokens processed after compression. For long agent traffic, Runware is not really in the running, and for media generation, Subconscious is not.

The two can sit in one product. A content or design agent can run its long planning loop on Subconscious, where briefs, prior outputs and feedback pile up into hundreds of thousands of tokens, then call Runware to batch many image or video tasks in one request. Plan for Runware's default seven-day expiry on output URLs by storing results yourself. Subconscious records no prompts or inputs, which helps when the briefs themselves are sensitive.

## What each one does

### Subconscious

Subconscious is an MIT CSAIL spinout in Kendall Square that builds inference for long-horizon agents, the workloads where a single trace runs past 200K tokens and often into the millions. Its runtime drops in as a replacement for vLLM or SGLang. Instead of rereading an ever-growing context on every step, it prunes the KV cache and preserves suffix state, and Subconscious co-designs the runtime with post-trained model variants it calls Marathon. Against open models on standard inference, Subconscious delivers 2x faster task completion, delivers a 5M+ effective context window, cuts cost 50% and up to 80%, and scores neutral to 10% better on agentic benchmarks.

### Runware

Runware sells what it calls the lowest-cost API for media generation, and it claims more than 1M developers. One endpoint covers image, video, audio, 3D and text. Every request is a task with the same shape, so switching from a Kling video to a Seedream image mostly means changing the model ID. The published rate sheet lists 300+ priced models, with images from fractions of a cent to a few cents each and video billed per second, like Seedance 2.5 at about $0.10 a second at 480p.
