  Qwen3.8 Free on AIHubMix: Fix 429s, "Rate Limited by Provider", and a Drained Token Pool

  Most problems with qwen3.8-max-free and qwen3.8-flash-free come from three places: the free-tier caps, the campaign capacity GMI Cloud has set aside upstream, and how quickly thinking tokens and agent context drain a 1M-token daily pool. Some of these show up as errors. Others show up as an odd-looking answer, or an empty quota by lunchtime. Alongside them, the everyday API errors still apply: a wrong key or model ID, a context that's too long, a broken tool-call history, JSON mode, content mode

  x402 Tutorial: Let Your AI Agent Top Up AIHubMix with USDC

  AIHubMix now accepts USDC top-ups. Your AI agent can add credit to its own account with the USDC in its wallet: no web page to open, and no one has to click a button. With x402, a top-up can be as small as $1. The agent tops up as it goes, so you don't have to load a large balance in advance. It takes two steps: get a token, a wallet, and some USDC ready on the web and in an app, then run our ready-made top-up script with one command. About 20 seconds after payment, the credit shows up in yo

  Moving to Gemini 4 Argon from Gemini 3.1 Pro or 3.8 Flash: What Breaks and How to Fix It

  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

  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

  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

  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

  Which AIHubMix Free Model to Use for JanitorAI Roleplay

  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

  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
