Muse Spark 1.3
Meta is a new model provider in Cursor. Teams and Enterprise admins who configured model access before Meta was available need to enable the Meta provider before Muse Spark 1.3 appears for their members.
Muse Spark 1.3 is Meta's flagship model and the first Meta model available in Cursor. It is built for agentic coding: long tool-use chains, multi-step debugging, and large-repository work.
Strengths
- Six effort levels: minimal, low, medium, high (the default), extra high, and max. Higher efforts spend more reasoning tokens per step and score higher on CursorBench; drop to low or minimal for faster, cheaper responses on simpler tasks.
- 300k token context window, or 1M in Max Mode at the same per-token rates.
- Low per-token price for a flagship model: $1.25 per million input tokens and $4.25 per million output tokens.
Tools
Muse Spark 1.3 has access to all agent tools when used with Cursor including:
Find files by name, read directory structures, and grep for patterns.
Generate search queries and fetch results from the web.
Read file contents, including images for vision-capable models.
Suggest edits and apply them automatically.
Execute terminal commands and monitor output.
Control a browser to take screenshots, test applications, and verify visual changes. See the Browser documentation.
Generate images from text descriptions or reference images.
Ask clarifying questions while continuing to work in the background.
Retrieve rules based on type and description.

Pricing
Cursor plans include two usage pools. Muse Spark 1.3 draws from the third-party Other Models pool, which charges at the rates below. All prices are per million tokens.
| Name | ||||
|---|---|---|---|---|
| $1.25 | - | $0.15 | $4.25 |
Prompts bill at the base per-token rates above, including in Max Mode above 300k tokens. Cached input is billed at $0.15 per million tokens; there is no long-context multiplier and no cache-write charge.
Data retention
Muse Spark 1.3 runs under Cursor's standard provider terms. See Meta's zero data retention policy and Cursor's data use overview.
