Benchmarks
These two models do not currently report scores on any of the same benchmark suites, so there is no like-for-like capability comparison to show. Rather than pad the page with one-sided numbers, the benchmark leaderboards list every score we do hold.
What each model is for
Gemini 3.1 Pro
Google · Frontier
A mid-cycle upgrade to Gemini 3 Pro, released after rapid iteration on feedback from the November 3 Pro launch. Google positions it for the most complex tasks, with the clearest gains in ambitious agentic workflows. Keeps the 1M-token context window and full multimodal input.
- Agentic workflow execution
- Complex multi-step reasoning
- 1M-token context
- Text, image, audio and video input
Muse Spark 1.2
Meta · Frontier
Meta Superintelligence Labs' flagship line, and Meta's entry into the agentic coding market via the Meta Model API rather than open weights. Muse Spark plans work, delegates to subagents, writes scripts or drives UIs directly, and debugs from screenshots. It pairs a 1M-token context window with full multimodal input (images, video and PDFs) plus built-in search with citations, structured output and parallel tool calling.
- Agentic execution with subagent delegation
- Coding, with particular strength on frontend and design work
- 1M-token context
- Images, video and PDF input
Frequently asked questions
Which is cheaper, Gemini 3.1 Pro or Muse Spark 1.2?
Muse Spark 1.2 is the cheaper of the two by a wide margin: $2.15 per million tokens blended against $5.00, roughly 2.3× less. A single 100K-input, 10K-output job costs $0.168 on Muse Spark 1.2 against $0.320 on Gemini 3.1 Pro. Blended cost weights input at 70% and output at 30%; price your own token split for an exact answer, since the cheaper model on a blended basis is not always cheaper for your workload.
Which has the larger context window, Gemini 3.1 Pro or Muse Spark 1.2?
Muse Spark 1.2 takes a 1,049,000-token context window against 1,000,000, giving a modest edge for long documents or whole-codebase work. The context window caps everything in a single request: prompt, retrieved documents, conversation history and the model’s own output all share it.
Can I compare Gemini 3.1 Pro and Muse Spark 1.2 on my own numbers?
Yes. Open both in the side-by-side comparison tool to see every field at once, or use the token calculator to price your actual prompt and monthly request volume against each model. Both are free and need no sign-up.
