  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

  Update (October 23, 2026): xiaomi-mimo-v2.5-pro-free was retired on 21 October 2026 and now returns 404 model_retired. If a saved configuration still uses it, switch the Model field to xiaomi-mimo-v2.6-pro-free. 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

  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

  How to Use AIHubMix Free Models in JanitorAI: Proxy Setup and Common Errors

  JanitorAI can talk to any OpenAI-compatible API through its Proxy option, and AIHubMix is one.

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

  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

  What Is Mistral Large 4? A Trillion-Parameter Specialist from Europe

  Mistral Large 4 is Mistral AI's new flagship. It has about one trillion parameters, it is trained from scratch in Europe, and its open weights are due at the end of October 2026. It isn't the smartest model available. What makes it notable is that it leads in a few areas where closed flagships either refuse or fall behind: defensive security work, locating objects in images, and legal research agents. Mistral released it on October 6, 2026 as a public preview. Its nickname is "Le Chonk". This

  Migrating from Claude Haiku 4.5 to 5.5: Five 400 Errors and the Quiet Changes

  Changing claude-haiku-4-5 to claude-haiku-5-5 is the smallest part of this migration. Five request patterns that worked on Haiku 4.5 now return a 400 error, and several more changes fail no request but alter what you get back, what it costs, or how the model behaves inside an agent. Anthropic says existing Haiku 4.5 prompts should work well on Haiku 5.5 without changes. The request code around those prompts is a different story. This post lists each problem as you'll meet it: what you'll see,
