Summary

Meta releases Muse Spark 1.1, a low-cost model that outperforms competitors in agentic tasks like tool use and financial agents, though it falls behind in coding benchmarks. Priced at $1.25/M input and $4.25/M output, it positions itself as a budget model for agent workflows.

BREAKING: Meta just dropped Muse Spark 1.1

everyone’s reading Meta’s Muse Spark 1.1 wrong

it’s not a GPT-5.5 rival. it’s the first model that beats Opus 4.8 at being an AGENT

and it’s priced like a budget model:

$1.25 / 1M input $4.25 / 1M output

[ where it actually wins: ]

professional tool use → JobBench 54.7 vs Opus 48.4 · GPT-5.5 38.3 · Gemini 15.9

it doesn’t edge them out. it laps them

scaled tool use → MCP Atlas 88.1 (beats everyone) reasoning w/ tools → Humanity’s Last Exam 62.1 (beats everyone) financial agents → Finance Agent v2 57.2 (beats everyone)

best use case:

agents that OPERATE, not chat

  • software that clicks, fills, and files across desktop/mobile/browser
  • tool-orchestration workflows that call 10 APIs to finish one job
  • financial + research agents running long tasks with subagents in parallel

build the worker. run it cheap. at scale

but know the tradeoff:

it LOSES every coding benchmark Terminal-Bench, SWE-Bench Pro, DeepSWE → all go to Opus 4.8 or GPT-5.5

so the play is simple:

  • writing code → Opus 4.8
  • running agents that use tools → Muse Spark 1.1, at a fraction of the cost

good model for saving at costs and increasing a bit an agentic

even Mark decided to turn on

@DeRonin_ dude, kinda wild it’s priced so low. do you think it’ll shake up the market or nah?
