Meta\u2019s benchmark results are promising; independent public coding leaderboards have not yet verified the same model-and-agent combinations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This review separates the model from the agent, official scores from independent evidence, and standard pricing from the Contributor tier\u2019s data-use trade-off. In our tests, the model completed a Python idempotency fix, a compatibility-preserving TypeScript refactor, and a repository-wide JSONL feature with no retries. Muse Code agent execution was not tested, and tool-call reliability was not tested.

Its strongest public story is value: $0.10 input and $0.20 output per million tokens on the Contributor model. That tier may be used to improve Meta products, while the more expensive standard model is not used for that purpose.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The performance story needs more restraint. Meta reports 82.9% on Terminal-Bench 2.1 for Muse Spark 1.2 with Muse Code and 59.3% on DeepSWE. Those are Meta-run results. The public Terminal-Bench and DeepSWE boards did not list Muse Spark 1.2 when checked on August 7, 2026. Artificial Analysis offers a useful independent cross-check, where the current Intelligence Index is 57 and the model ranks #12 of 185.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Best reason to try it now:<\/strong> low Contributor pricing, large context, and an API that follows the familiar OpenAI client pattern.<\/li>\n\n\n\n<li><strong>Best reason to stay cautious:<\/strong> three controlled base-model tasks do not establish Muse Code agent reliability, tool-call quality, or performance across a large production repository.<\/li>\n\n\n\n<li><strong>Important privacy choice:<\/strong> use the standard model for code or prompts you do not want used to improve Meta products.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"muse-spark-1-2-at-a-glance\" class=\"wp-block-heading\">Muse

Contributor pricing comes with a data-use trade-off. Standard output and reasoning tokens can raise the real cost. Meta\u2019s top coding numbers have not been reproduced as matching entries on the public Terminal-Bench or DeepSWE boards, and our hands-on sample covers three base-model tasks rather than Muse Code agent execution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The sensible move is a controlled trial on non-sensitive code with raw usage and local verification saved. Treat the measured cost and latency as a small-task sample, then test your own repository size, failure recovery, and agent workflow before choosing it for production.<\/p>\n\n\n\n<h2 id=\"muse-spark-1-2-faq\" class=\"wp-block-heading\">Muse Spark 1.2 FAQ<\/h2>\n\n\n\n<section class=\"muse-faq\" aria-label=\"Muse Spark 1.2 frequently asked questions\">\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">What is Muse Spark 1.2?<\/h3>\n    <p>Muse Spark 1.2 is Meta\u2019s coding-focused model, launched on August 5, 2026, with a 1M-token context window and access through Muse Code, the Meta Model API, and OpenRouter.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">Is Muse Spark 1.2 the same as Muse Code?<\/h3>\n    <p>No. Muse Spark 1.2 is the model; Muse Code is a separate beta terminal agent powered by it. Muse Code adds product features such as subagents, isolated git worktrees, event logging, resume, and bundled skills.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">How much does the Muse Spark 1.2 API cost?<\/h3>\n    <p>The standard model costs $1.25 input, $0.15 cached input, and $4.25 output per million tokens. The Contributor model costs $0.10 input, $0.002 cached input, and $0.20 output.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">Does Meta use Muse Spark API data for training?<\/h3>\n    <p>Meta says standard-tier data is not used to improve Meta products. Contributor-tier data may be used to improve Meta products, so private or proprietary code should use the standard route unless an organization approves otherwise.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">Is Muse Spark 1.2 on the public Terminal-Bench or DeepSWE leaderboards?<\/h3>\n    <p>It was not listed on either public board when checked on August 7, 2026. Meta reports 82.9% on Terminal-Bench 2.1 with Muse Code and 59.3% on DeepSWE, but those are Meta-run results.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">Has Muse Spark 1.2 been tested hands-on in this review?<\/h3>\n    <p>Yes. In three single-attempt base-model tests, Muse Spark 1.2 passed a Python bug fix, a TypeScript refactor, and a JSONL repository feature. Average latency was 12.98 seconds and total reported cost was $0.045362. Muse Code agent and tool-call reliability were not tested.<\/p>\n  <\/div>\n  <div class=\"muse-faq-item\">\n    <h3 style=\"margin:0 0 7px;color:inherit;font-size:20px;line-height:1.25\">How can developers access Muse Spark 1.2?<\/h3>\n    <p>Meta lists three routes: the Muse Code beta terminal agent, the Meta Model API, and OpenRouter. The official cookbook uses an OpenAI SDK-compatible client with the base URL https:\/\/api.meta.ai\/v1.<\/p>\n  <\/div>\n<\/section>\n\n\n\n<script type=\"application\/ld+json\" class=\"muse-faq-schema\">{\n    \"@context\": \"https:\\\/\\\/schema.org\",\n    \"@type\": \"FAQPage\",\n    \"mainEntity\": [\n        {\n            \"@type\": \"Question\",\n            \"name\": \"What is Muse Spark 1.2?\",\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"Muse Spark 1.2 is Meta\\u2019s coding-focused model, launched on August 5, 2026, with a 1M-token context window and access through Muse Code, the Meta Model API, and OpenRouter.\"\n            }\n        },\n        {\n            \"@type\": \"Question\",\n            \"name\": \"Is Muse Spark 1.2 the same as Muse Code?\",\n            \"acceptedAnswer\": {\n                \"@type\": \"Answer\",\n                \"text\": \"No. Muse Spark 1.2 is the model; Muse Code is a separate beta terminal agent powered by it.
