Anthropic prices its IPO this week on about $81 billion of run-rate token revenue, and the floor under that business just moved. [Meta](https://theinference.org/markets/companies/meta) released Muse Ember yesterday, its smallest model, and the price is the news: [$0.10 per million input tokens on the Meta Model API](https://research.meta.ai/blog/muse-ember), aimed at the steps software agents repeat all day, from tool calls and coding subtasks to routing, extraction and long-document parsing [1]. The independent benchmarking service Artificial Analysis has already measured it: [36 on its intelligence index at $0.14 per task](https://artificialanalysis.ai/models/muse-ember) [8]. On Meta's comparison, that matches Claude Haiku 5.5's best score at about a third of the cost per task and beats every GPT-6 Luna setting [1]. The volume end of inference just got repriced. *Chart: **Meta set the floor on cost per agent task** Bar chart of cost per Artificial Analysis task for Muse Spark 1.3, Claude Haiku 5.5, GPT-6 Luna and Muse Ember* *Cost per Artificial Analysis Intelligence Index task at max reasoning effort, in dollars. Ember's $0.14 confirmed by Artificial Analysis; Haiku 5.5 and Luna figures as presented in Meta's announcement; Spark 1.3 is Meta's prior mid-weight model. [1][8]* ## A cheap executor changes how agent systems are built Ember was trained with Muse Wonder Full, Meta's frontier trainer, and its stated job is the subagent slot: "Muse Wonder plans, Muse Ember handles the volume" [1]. Agents spend most of their tokens on small structured steps, so routing those steps to a cheap executor changes the unit economics of every agent fleet [1]. The partner accounts in Meta's announcement point the same way: Cline's founder says teams run Ember as the subagent to cut costs, Box says it scores contracts against negotiation playbooks clause by clause, and [Cloudflare](https://theinference.org/markets/companies/cloudflare) and You.com report speed and token savings in early testing [1]. TechCrunch notes it is cost-competitive with open-source flash models from [DeepSeek](https://theinference.org/markets/companies/deepseek) and GLM [6]. Adoption started same-day: the developer Simon Willison had Ember wired into his own command-line tooling, driven from his phone, before the release was a day old [2]. The limit is visible too: on FrontierCode 2.0, engineering work judged on whether it merges, Haiku still leads [1]. ## Anthropic prices its IPO on the opposite bet [Anthropic](https://theinference.org/markets/companies/anthropic) set its [IPO range this morning at $70 to $78 a share](https://www.cnbc.com/2026/11/10/anthropic-sets-price-range-of-70-to-78-in-upcoming-ipo.html) and plans to price on November 18, trading on Nasdaq as ANT [4]. The filing behind it carries roughly $81 billion in run-rate revenue, most of it tokens sold to businesses [4]. [A draft circulated to banks on Monday](https://www.msn.com/en-us/money/companies/exclusive-anthropic-s-nearly-70-billion-ipo-plan-briefly-circulated-to-banks-then-retracted/ar-AA2h6Eha) showed a raise of nearly $70 billion before Anthropic retracted it as inaccurate [5]. The obligations underneath are the point: nearly $900 billion in computing commitments, which token sales have to fund [5]. Haiku is the volume workhorse in that machine, and Artificial Analysis lists [Anthropic's new flagship, Claude Fable 5.2](https://theinference.org/article/anthropic-cuts-fable-5-2-prices-20-on-ipo-roadshow-eve-and-google-and-broadcom-shareholders-carry-the-bill), at $26.54 per task against Ember's $0.14 [8]. *Chart: **Anthropic's flagship costs about 190 times Ember per task** Column chart of cost per Artificial Analysis task for Claude Fable 5.2, Claude Haiku 5.5 and Muse Ember* *Cost per Artificial Analysis Intelligence Index task, in dollars, at listed settings. Anthropic's flagship Claude Fable 5.2 and volume model Claude Haiku 5.5 against Meta's Muse Ember. Source: Artificial Analysis, November 2026. [8]* Meta can hold the floor because it is paying with advertising money: about 97% of its revenue is still ads [3][7], and [Truist](https://theinference.org/markets/companies/truist-financial) models only $5.2 billion of Meta enterprise revenue by 2030 against a $461 billion enterprise spend pool [3]. Meta is buying the volume tier, not harvesting it. At 14 cents a task, contract review stops being a pilot and becomes a line item. Whoever holds the volume tier when fleets make that switch holds the default, and the revenue that follows. Anthropic's IPO investors are underwriting the opposite bet. ## Takeaway Meta's Muse Ember resets the price of agent volume work at $0.14 a task, a third of Claude Haiku's cost, hours before Anthropic prices an IPO underwritten by token revenue at the very tier Meta just repriced. ## Sources 1.
