Google shipped Gemini 4 Argon, its first full Pro-class model in 8-10 months, now #1 on Arena Text, demoed live with Google DeepMind staff. Anthropic had a big week: new distillation defenses cutting data harvesting by 90-99%, OpenTelemetry support for agent observability, restored subscription access for the Agent SDK, and a reported $16.8B Q3 revenue ahead of a possible November IPO. Also covered: NVIDIA's Nemotron 3.5 Super VL open vision model, rumors of a NVIDIA-Reflection acquisition, Nathan Benaich's State of AI 2026 report findings on AI-driven research (RSI), and highlights from AI Engineer NYC including talks on code quality in the AI era and the shift toward managing swarms of agents. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Meta's Muse Spark Open model and how big is it? Muse Spark Open is Meta's open-weight model with 816B total parameters and 42B active parameters, supporting 1M context length with multimodal input and text output. Meta calls it the most capable US open-weight model released to date. It requires roughly 700GB of VRAM for NVFP4 inference, or two M5 Ultra Mac Studios per Mark Zuckerberg, and its license caps commercial use at $20M annual revenue before requiring different terms. _Developers evaluating open-weight models for self-hosting can follow releases like this one on daily.dev._ ### How does Gemini 4 Argon pricing compare and when does it change? Gemini 4 Argon is priced at $2 per million input tokens and $10 per million output tokens through November 30, after which it rises to $4 in / $20 out. It is generally available in the Gemini API, AI Studio, the Gemini app for Pro and Ultra tiers, and Antigravity for Ultra, and ranks #1 on Arena Text benchmarks. _Teams budgeting for model costs ahead of pricing changes can track updates like this via daily.dev._ ### What did Anthropic report as Q3 revenue ahead of its IPO? Anthropic's Q3 revenue reportedly reached approximately $16.8 billion, up about 45% from Q2, with the company adjusted profitable for a second consecutive quarter and cash flow positive. The figures came from a closed-door investor day ahead of a reported November IPO, rather than an official public disclosure. _Developers weighing which AI vendor to build on can follow financial signals like this on daily.dev._ --- Tags: [#open-source](https://daily.dev/tags/open-source), [#llm](https://daily.dev/tags/llm), [#anthropic](https://daily.dev/tags/anthropic), [#google-gemini](https://daily.dev/tags/google-gemini) [View this post on daily.dev](https://daily.dev/posts/meta-ships-muse-wonder-and-an-816b-open-model-gemini-4-argon-is-here-more-2qozbvdju) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Meta ships Muse Wonder AND an 816B open model, Gemini 4 Argon is here & more","url":"https://daily.dev/posts/meta-ships-muse-wonder-and-an-816b-open-model-gemini-4-argon-is-here-more-2qozbvdju","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/meta-ships-muse-wonder-and-an-816b-open-model-gemini-4-argon-is-here-more-2qozbvdju"},"datePublished":"2026-10-16T03:24:21.918Z","dateModified":"2026-10-16T03:24:50.635Z","description":"A weekly AI news roundup covers Meta becoming a frontier lab with the release of Muse Wonder (ranked #2 on Arena Text) and the surprise drop of Muse Spark...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ddddbad913bfd45e319bdbffb414b812?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ddddbad913bfd45e319bdbffb414b812?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"ThursdAI","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"ThursdAI","logo":"https://media.daily.dev/image/upload/s--l8bfn0ZB--/f_auto,q_auto/v1780213209/logos/thursdai?_a=BAMAMiWQ0","url":"https://daily.dev/sources/thursdai"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/meta-ships-muse-wonder-and-an-816b-open-model-gemini-4-argon-is-here-more-2qozbvdju","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,llm,anthropic,google-gemini","timeRequired":"PT19M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"ThursdAI","item":"https://daily.dev/sources/thursdai"},{"@type":"ListItem","position":3,"name":"Meta ships Muse Wonder AND an 816B open model, Gemini 4 Argon is here & more"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/meta-ships-muse-wonder-and-an-816b-open-model-gemini-4-argon-is-here-more-2qozbvdju#faq","mainEntity":[{"@type":"Question","name":"What is Meta's Muse Spark Open model and how big is it?","acceptedAnswer":{"@type":"Answer","text":"Muse Spark Open is Meta's open-weight model with 816B total parameters and 42B active parameters, supporting 1M context length with multimodal input and text output.
