Meta's Muse Spark 1.1 achieves 99.99% cache hit rate on large project

A recent analysis of Meta's Muse Spark 1.1 model revealed an exceptionally high cache hit rate of 99.9932% when processing a large software development project. The model consumed over 67.9 million tokens, with nearly all served from cache. However, the precise caching mechanism remains unclear, as the uncached portion consistently amounted to exactly 4 tokens per request, regardless of the request's complexity or role. This caching efficiency significantly reduced costs, absorbing about 85% of the potential expense, though the exact savings are impacted by cache read costs and uncached output tokens. AI

IMPACT Demonstrates significant cost savings potential for agent workloads through advanced caching, though the exact mechanism requires further clarification.

    We sent 67.9M tokens to Muse Spark 1.1. It cached all but 4 per request.

    <p>Meta's Muse Spark 1.1 showed up on OpenRouter on July 16. We handed it a Statement of Work the same day and let it build something end to end — not a benchmark prompt, a whole software project: spec, plan, pseudocode, code, review, tests, build, sprint review. One model in eve…
