• Moving to Gemini 4 Argon from Gemini 3.1 Pro or 3.8 Flash: What Breaks and How to Fix It — October 14, 2026

  Gemini 4 Argon became generally available on October 13, 2026, under the model ID gemini-4-argon, on the paid Gemini API, on Vertex AI and on AIHubMix. AIHubMix lists it at $2 per million input tokens, $10 per million output tokens and $0.10 per million cached input tokens, the same as Google's introductory rate. Google's rate runs until November 30; from December 1 it doubles to $4 and $20. [TBD: AIHubMix price from December 1] Changing the model string is the easy part. Google's What's new i

• Gemini 4 Argon Thinking Levels and Long Decode: Defaults, Costs and When to Use Each — October 14, 2026

  Gemini 4 Argon became generally available on October 13, 2026, and with it Google documented the two settings that decide what an Argon request costs and how long it takes: the thinking level and the output limit. Argon offers three thinking levels, low, medium and high, and defaults to medium. Responses stop at 64K tokens unless you turn on long decode, which lets a single response run to 1M tokens. There's a catch in the defaults. Every published Argon benchmark ran at high: Google evaluated

• Gemini 4 Argon: Frontier Scores, a 1M-Token Output Limit, and How to Call It Now — October 13, 2026

  Gemini 4 Argon is Google's first Gemini 4 model and its strongest so far. Independent testers put it level with GPT-6 Astra, it tops the Vals Index for finance, legal and tax work, and it can write up to 1M tokens in a single answer. It also costs less per token than Astra, even after its introductory price ends. Argon became generally available on October 13, 2026. Google's announcement opened it to developers and enterprises through the paid Gemini API, Google AI Studio and Vertex AI, and to

• Gemini 4 Argon Pricing: Cheap Per Token, Not Per Task — October 13, 2026

  Gemini 4 Argon became generally available on October 13, 2026 at an introductory $2 per million input tokens and $10 per million output tokens. That price runs through November 30. From December 1 it doubles to $4/$20. Either way Argon is far below GPT-6 Astra's $10/$50 per token: a fifth of Astra's list price now, two fifths from December. Per task, most of that gap disappears. Argon writes a lot: about 62k output tokens per Artificial Analysis task, roughly 2.3 times as many as Astra. Artifi

• AIHubMix Supports JanitorAI Roleplay Chat, with Zero Data Retention on by Default — October 13, 2026

  AIHubMix supports roleplay chat. Connect it to JanitorAI as a proxy, pick a free model, and your characters reply through AIHubMix. Every AIHubMix account also has Zero Data Retention (ZDR) turned on by default, so we don't log, store, or keep your messages, your character prompts, or the model's replies. The short version: * Roleplay chat: AIHubMix connects to JanitorAI as a proxy. Dozens of free models are available, and our first pick for roleplay chat is xiaomi-mimo-v2.6-pro-free. * Ze

• Which AIHubMix Free Model to Use for JanitorAI Roleplay — October 13, 2026

  Short answer: start with xiaomi-mimo-v2.6-pro-free, save one or two general chat models as backups, and keep low-cap and coding models out of long sessions. Treat that as a starting point, not a ranking. There's no official roleplay benchmark for AIHubMix's free models, and none of the model pages mention roleplay. This post covers how to choose and how to test, so you can decide based on your own characters. Why there's no "best model" list AIHubMix's free model catalog lists dozens of mod

• AIHubMix Free Model Limits for JanitorAI: 10 Trial Calls, the $1 Unlock, and the Token Cap — October 13, 2026

  A new AIHubMix account gets 10 trial calls in total, shared across every free model. They are not 10 per day or one every few minutes. A one-time top-up of $1 or more switches the account to daily quotas: 100 requests a day, 10 a minute, and 1M tokens a day, shared across the whole free catalog. For long JanitorAI chats, the 1M-token pool is usually what runs out first, well before you reach 100 replies. The rest of this guide explains each limit, shows how fast a JanitorAI chat uses the token

• How to Pay on AIHubMix with Alipay — October 13, 2026

  To unlock AIHubMix's free models for everyday use, you need one top-up of $1 or more. The $1 amount works through the Alipay option on the top-up page, paid from the Alipay app. Card checkout through Stripe, including the Alipay button inside the Stripe checkout, starts at $15. After any top-up of $1 or more, the AIHubMix free models page says your account "permanently" switches to daily quotas: 100 requests a day, 10 a minute, and 1M tokens a day across all free models. It's a one-time step,

• How to Use AIHubMix Free Models in JanitorAI: Proxy Setup and Common Errors — October 13, 2026

  JanitorAI can talk to any OpenAI-compatible API through its Proxy option, and AIHubMix is one. The whole setup is four values typed into one form: Name: anything you like, e.g. AIHubMix MiMo Proxy URL: https://aihubmix.com/v1/chat/completions API key: your AIHubMix key Model: xiaomi-mimo-v2.6-pro-free Leave Custom prompt empty, press Test, then Add, and refresh the page.

• Codex Compaction Fails With "response protection is unavailable": It's the Web Search, Not Your Context — October 10, 2026

  Since October 8, 2026, long Codex sessions have been dying the moment they try to compact. The error reads stream disconnected before completion: response protection is unavailable, retries don't help, and the conversation can't continue. Most reports involve gpt-6.1-sol, but gpt-6-astra and gpt-5.6-sol fail the same way. It shows up behind self-hosted proxies, and it also shows up in the official Codex app with a direct ChatGPT login. The short answer: the context isn't too big, and your netw
