Muse Spark 1.1
Meta · Released Jul 2026
Meta's first paid AI model and first salvo in the commercial coding market — $1.25/$4.25 per 1M tokens with 1M context, native subagent orchestration, MCP/tool support, and computer-use capability at roughly 4x under Anthropic/OpenAI pricing. Leads on tool-use benchmarks but trails Opus 4.8 on pure coding by 7 points on SWE-Bench Pro. Closed-weight, US-only public preview. Best for teams prioritizing tool-use orchestration at low cost.
Is it right for you?
Good for
- Scaled tool use and MCP orchestration — leads MCP Atlas (88.1) and JobBench (54.7), ahead of Opus 4.8 and GPT-5.5
- Cost-sensitive agentic workloads — $1.25/$4.25 pricing undercuts Anthropic/OpenAI flagship by ~4x
- Multi-agent pipelines — native primary-agent/subagent orchestration with parallel execution
- Multimodal reasoning — handles images, video, documents alongside code; 1M context actively managed
Not good for
- Frontier coding accuracy — trails Opus 4.8 by 7 pts on SWE-Bench Pro, third on DeepSWE 1.1
- EU-based or non-US developers — API is US-only public preview; no EU access yet
- Open-weight or self-hosting requirements — proprietary and closed-weight (unlike Llama)
How it performs by task
Code generation
Trails Opus 4.8 by 7 pts on SWE-Bench Pro; third on DeepSWE 1.1 behind GPT-5.5 and Opus 4.8
Agentic coding
Best-in-class tool use (MCP Atlas 88.1, JobBench 54.7); native subagent orchestration with parallel execution
Computer use
OSWorld-Verified 80.8 trails Opus 4.8 (83.4); can drive a real desktop using hybrid scripting/clicking approach
Multimodal understanding
Handles images, video, documents; ties Opus 4.8 on several vision benchmarks per vendor charts
Reasoning
SOTA on Humanity's Last Exam and FinanceBench; lags on pure coding reasoning benchmarks
