# Muse Spark 1.1

Meta, released 2026-07-09

**Verdict: conditional.** 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. Last verified 2026-07-10.

## Pricing

- Input: $1.25 / 1M tokens
- Output: $4.25 / 1M tokens
- Context: 1M tokens

## Strengths

- 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
- 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)
