The key race: paid Argon is out, and Large 4 weights are not
On October 13, 2026 Google said Gemini 4 Argon is globally available for developers and enterprises on the API in AI Studio and the Gemini platform, for Google AI Ultra subscribers in Google Antigravity, and for Google AI Ultra and Pro subscribers in the Gemini app and AI Mode in Search. Introductory API price is $2 per million input tokens and $10 per million output tokens, then $4 and $20 after November 30, 2026. The post describes a 1 million token unified input-output limit and says Fairwind is starting to add hundreds of partners. It also says the rest of the Gemini 4 family is still to come. The post does not put Argon on a free tier, and the API price card was not opened for this update.
Mistral on October 6 put Large 4 into a public preview on Mistral Studio: a 1-trillion-parameter model with 52 billion active parameters, trained on 3,800 NVIDIA Grace Blackwell GPUs in Mistral European datacenters. The company said open weights would follow by the end of October, after red-teaming. No weight file was downloaded for this update. The xAI Grok Voice 3.0 page, which showed no publication date in the fetch, prices the Voice Agent API at $0.08 a minute, the same as Grok Voice 2.0, and says grok-voice-latest has already switched. xAI own figures are an 86.9 Speech-to-Speech Index score and millions of Tesla conversations a day. That is a voice model, not a Grok 5 text release.
Who is ahead: investors heard $16.8 billion; a public filing is still separate
Two people who attended the Anthropic October 14 investor day in San Francisco told Reuters that third-quarter revenue was $16.8 billion, up from $11.6 billion in the second quarter and $4.7 billion in the first, and that the company said the quarter was profitable on an adjusted basis. Anthropic did not immediately comment. Reuters said the Financial Times first reported the quarterly figure, and that a public debut is likely after the November 2026 US midterm elections, citing earlier Reuters reporting rather than a new company date. The same story says analysts who met executives estimated a $110 billion year-end run rate, and it states a commitment of at least $518 billion over a decade and a target valuation over $2 trillion. The run-rate line is an analyst estimate. The quarterly dollars are what attendees said the company told them, not a filing.
The rules this week: an FTC demand, state suits, and an incident mandate
Axios reported that on Wednesday, October 14, the FTC sent civil investigative demands to Anthropic and OpenAI. A person familiar said each demand runs more than 50 pages and asks for documents on security incidents, safeguarding, marketing and privacy policies. An OpenAI spokesperson told Axios the company will engage constructively. Axios did not quote Anthropic. The same article said a group of state attorneys general sued OpenAI that day under consumer-protection laws for allegedly misleading users, including children. It did not name the states.
Axios also said the White House Super Intelligence Force, responding last week to Anthropic model use of government systems, told the industry that incident notice and remediation are mandatory, and that the Force was set to meet on Thursday, October 16. No public readout of that meeting was opened for this update.
What to watch through the midterms
Watch whether the Argon list price steps up on November 30 from $2 and $10 to $4 and $20 per million tokens, whether the rest of the Gemini 4 family leaves the still-to-come line, and whether Large 4 weights publish by the end of October. Watch whether grok-voice-latest stays on Voice 3.0 or a Grok 5 text model appears. Voice 3.0 does not close that gate.
Watch whether the $16.8 billion attendee figure shows up in a public registration statement, and whether the debut stays after the November midterms as Reuters has reported. Watch the FTC demands and the state consumer suits. Watch whether the Super Intelligence Force meeting Axios placed on October 16 produces a public incident rule beyond the mandate already described.
Humanoid members remain an embodied shipment race, not this model gate. Queued robotaxi, aircraft and vehicle items do not change who has a paid frontier model this week.
