It is called Muse Code, it runs in your terminal, and it arrived on August 5, 2026 alongside a new model named Muse Spark 1.2. If you have used Claude Code or OpenAI&#8217;s Codex, you already know the shape of this thing.<\/p>\n<p>The story here is price. Meta is charging a fraction of what its rivals ask, and there is an even cheaper tier if you let the company learn from your prompts. That trade is the real headline, so we will get to it in plain terms.<\/p>\n<p>Below: what Muse Code actually does, what it costs, how it lines up against the tools you already use, and whether it is worth installing today.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">In This Article<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#What_is_Meta_Muse_Code\" >What is Meta Muse Code?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#What_is_Muse_Spark_12\" >What is Muse Spark 1.2?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#How_much_does_Muse_Code_cost\" >How much does Muse Code cost?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#What_is_the_catch_with_the_cheap_contributor_tier\" >What is the catch with the cheap contributor tier?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#How_does_Muse_Code_compare_to_Claude_Code_and_Codex\" >How does Muse Code compare to Claude Code and Codex?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#Are_the_benchmarks_any_good\" >Are the benchmarks any good?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#Who_is_Muse_Code_actually_for\" >Who is Muse Code actually for?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#Quick_questions\" >Quick questions<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.brandligo.com\/blog\/meta-muse-code\/#The_takeaway\" >The takeaway<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Meta_Muse_Code\"><\/span>What is Meta Muse Code?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Muse Code is a terminal coding agent that plans a change, writes the code, and checks its own work across an entire repository. You install it from the command line on macOS or Linux, point it at a project, and describe the job in ordinary language. It then breaks the task into steps and runs them.<\/p>\n<p>What sets it apart from a simple chat box is how it manages long jobs. Muse Code can spin up several persistent subagents at once, run background agents while you keep working, and keep a local event log so a run can be replayed exactly or restarted safely if something breaks. It ships with a few built-in skills too, triggered by short commands like \/plan, \/grill and \/goal. It is in beta, and it is Meta&#8217;s first proper answer to the coding agents Anthropic and OpenAI shipped months ago.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Muse_Spark_12\"><\/span>What is Muse Spark 1.2?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Muse Spark 1.2 is the model doing the actual thinking inside Muse Code, and it is a coding-focused upgrade to the Muse Spark 1.1 model Meta released on July 9, 2026. It went live on August 5 in both Muse Code and the Meta Model API, with what Meta calls expanded global access.<\/p>\n<p>This is Meta&#8217;s third Muse Spark model in about four months. Version 1.0 arrived in April, 1.1 in July, and now 1.2. Meta says it trained the new version with more compute on coding tasks, longer-horizon training runs, and self-improvement loops where the model learns from its own attempts. In the announcement the company was blunt about the pace, calling 1.2 its next step toward the frontier with larger and much more capable models on the way. Translation: expect this to keep moving fast.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_much_does_Muse_Code_cost\"><\/span>How much does Muse Code cost?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Muse Code runs on token pricing, and the standard rate is low by current standards: about 1.25 dollars per million input tokens and 4.25 dollars per million output tokens, according to reporting from Engadget. There is also a cheaper contributor tier at roughly 0.10 dollars per million input and 0.20 dollars per million output, in exchange for Meta using your prompts to train its models.<\/p>\n<p>To put that in context, here is how the standard and contributor rates compare against Anthropic&#8217;s Sonnet 5, the model behind Claude Code.<\/p>\n<table>\n<thead>\n<tr>\n<th>Tool or model<\/th>\n<th>Input (per 1M tokens)<\/th>\n<th>Output (per 1M tokens)<\/th>\n<th>The trade-off<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Muse Spark 1.2 (standard)<\/td>\n<td>1.25 dollars<\/td>\n<td>4.25 dollars<\/td>\n<td>Pay the normal rate, keep your data<\/td>\n<\/tr>\n<tr>\n<td>Muse Spark 1.2 (contributor)<\/td>\n<td>0.10 dollars<\/td>\n<td>0.20 dollars<\/td>\n<td>Your prompts train Meta&#8217;s models<\/td>\n<\/tr>\n<tr>\n<td>Anthropic Sonnet 5<\/td>\n<td>3.00 dollars<\/td>\n<td>15.00 dollars<\/td>\n<td>Pay more, standard privacy terms<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Even the standard tier undercuts Sonnet 5 by a wide margin. The contributor tier is in a different league entirely.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_the_catch_with_the_cheap_contributor_tier\"><\/span>What is the catch with the cheap contributor tier?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The catch is simple: on the contributor tier, Meta uses your prompts to train its future models. You are paying with your data instead of your wallet. For a hobby project or a public code sample, that is a fine deal, maybe a great one, since you are getting frontier-adjacent coding help for pennies.<\/p>\n<p>For work code, it is a harder call. Coding prompts often carry proprietary logic, internal file names, API keys pasted by accident, and business rules a company would never want feeding a competitor&#8217;s model. Meta&#8217;s Chief AI Officer, Alexander Wang, framed the tier as a way to give developers much lower cost access. That is true. But if you build anything you cannot afford to leak, read your employer&#8217;s policy before you switch it on. The 90 percent discount is real, and so is what you hand over for it.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_does_Muse_Code_compare_to_Claude_Code_and_Codex\"><\/span>How does Muse Code compare to Claude Code and Codex?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Muse Code is a direct competitor to Claude Code and to Codex from <a href='https:\/\/www.brandligo.com\/companies\/openai'>OpenAI<\/a>, and Meta is not pretending otherwise. Both of those tools have been out for months and have larger user bases, more polish, and deeper ecosystem support. Meta is late, and it knows it.<\/p>\n<p>So Meta is competing where it can win, which is price. The playbook looks a lot like the one Chinese labs such as DeepSeek used to get noticed: ship something capable, charge far less, and let cost do the marketing. The same command-line agent idea also powers tools from <a href='https:\/\/www.brandligo.com\/companies\/google'>Google<\/a>, so the terminal is getting crowded fast. Muse Code&#8217;s pitch is not that it is the best agent in the room. It is that it is the cheapest one that might be good enough for what you are doing.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Are_the_benchmarks_any_good\"><\/span>Are the benchmarks any good?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>We do not fully know yet, because Meta published charts but not clean numbers for Muse Spark 1.2. The company says it tested the model on Terminal-Bench 2.1 (89 tasks), DeepSWE v1.1 (113 tasks), and its own 440-task internal coding benchmark, and compared it against Grok 4.5, Claude Opus 5, GPT-5.6 Terra, Gemini 3.6 Flash and Kimi K3.<\/p>\n<p>What Meta did not do is hand over plain, checkable scores for the new model in the launch post. For reference, the earlier Muse Spark 1.1 scored 80.0 on Terminal-Bench 2.1. Until independent testers run 1.2 and publish results, treat the launch charts as a marketing claim, not proof. Meta also mentioned gains on GPU kernel optimization work on Nvidia Hopper hardware, which matters for training speed but tells a regular developer very little about day-to-day coding quality.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Who_is_Muse_Code_actually_for\"><\/span>Who is Muse Code actually for?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Muse Code is for developers who want a capable terminal agent and care more about cost than about brand or polish. If you are a student, an indie hacker, or someone running side projects on macOS or Linux, the contributor tier at roughly 0.10 and 0.20 dollars per million tokens is hard to argue with, and your prompts probably are not sensitive anyway.<\/p>\n<p>If you work on proprietary code inside a company, slow down. The standard tier keeps your data out of Meta&#8217;s training set and still costs less than Sonnet 5, so that is the sane starting point. And since it is a beta that only runs on macOS and Linux, Windows users and anyone who needs a stable, supported tool for production work should probably wait a version or two. This is a fast-moving line, and 1.3 is clearly not far off.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Quick_questions\"><\/span>Quick questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Is Muse Code free?<\/strong> No. It runs on paid token pricing, though the contributor tier is cheap enough to feel close to free for light use, as long as you accept that your prompts train Meta&#8217;s models.<\/p>\n<p><strong>Does it work on Windows?<\/strong> Not at launch. The beta supports macOS and Linux only, installed from the command line.<\/p>\n<p><strong>Is Muse Spark 1.2 better than Claude Opus 5 or GPT-5.6?<\/strong> Unclear. Meta benchmarked against those models but did not publish plain scores for 1.2, so wait for independent tests before believing any ranking.<\/p>\n<p><strong>What is the difference between Muse Code and Muse Spark 1.2?<\/strong> Muse Spark 1.2 is the model. Muse Code is the terminal tool that uses it to plan, write and check code for you.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_takeaway\"><\/span>The takeaway<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If your code is not sensitive, install Muse Code on the contributor tier this week and let it earn or lose your trust on a real task. If your code is sensitive, use the standard tier or wait for independent benchmarks, because a 90 percent discount that trains a rival lab on your work is not a discount for everyone. What makes this launch worth watching is the strategy. Meta is betting it can win on price where it cannot yet win on quality, and that kind of pressure is good news for anyone paying the bills.<\/p>\n<p><strong>About this article.<\/strong> Written and fact-checked by the Brandligo editorial desk.
