ジェヴ

Jev

Jev is the first System One model from TypeSafe AI, released on 15 September 2026. Unlike an LLM it generates no text: give it a state (text or JSON) and it returns typed values — Choice (classification), Score (rating) and Noul (a 0–1 truth value) — each with probabilities and a calibrated confidence. Because no string comes back, there is nothing to parse and nothing to validate. Vendor-published figures are 70–500 ms end to end and $0.042 per million input tokens, with output tokens free. Questions in one request are evaluated in parallel, so stacking them barely changes latency — which suits support triage, LLM guardrails and RAG re-ranking, where the same judgement repeats at volume. Still in early access behind a waitlist as of October 2026 and also listed on OpenRouter; the docs state that CJK scripts are accepted with lower accuracy than English. On 9 October 2026 Microsoft released Microsoft-Decision-1 with the same price and question types.

Claude MaxのAPIクレジットとは【2026年10月最新】毎月$100〜の受け取り方・使える範囲・Claude Codeは対象か・Haiku 5.5で何回動くか

2026年10月7日（米国時間）、AnthropicはClaudeのMax・Teamプランに毎月のAPIクレジットを付けると発表しました。Max 5xは月$100、Max 20xは月$200、Teamは1席あたりStandard $20・Premium $100をチームで1つの残高にまとめ、上限は$500です。この記事では、Xで食い違って広まったTeamの付き方（オーナー1人が受け取るプール方式）を公式ヘルプにもとづいて正し、使える範囲（Claude API・Managed Agents・Agent SDK・APIキーで動かすclaude -p）と使えない範囲（対話で使うClaude Code・Bedrock等の経由）、claude.aiの請求設定から組織を連携する受け取り方、7日の待機期間と繰り越し不可の条件を整理します。あわせて、同時公開のClaude Haiku 5.5の料金（入力$0.10・出力$0.50／100万トークン）で$100がどれだけの処理になるかを試算し、Pro・Max・Teamの選び方の目安を示します。

What Jev Is [October 2026]: The AI That Generates No Text — How to Use It, Pricing, and How It Differs from Microsoft-Decision-1

On 9 October 2026, Microsoft released Microsoft-Decision-1, a decision model at the same price as Jev ($0.042 per million input tokens, free output) and with the same question types. This article explains what Jev — released by TypeSafe AI on 15 September 2026 — is: a System One model that generates no text and returns Choice (classification), Score (rating) and Noul (a 0–1 truth value) with probabilities; speculative fan-out, where stacking questions barely changes latency; how to get started from the waitlist to the Python SDK, HTTP API and Claude Code skill; routing low-confidence answers to people; and use cases. It then compares Jev with Microsoft-Decision-1 (access, context length, availability, Japanese support), explains which to choose and whether you can use them from Japan, and covers Jev's latest status in October (Series A, rate limits, OpenRouter listing). It also covers the official note that CJK accuracy is lower than English and the weak spots TypeSafe publishes itself.

What GPT-6 Astra Is [September 2026]: Which ChatGPT Plans Include It, API Pricing, and How to Split Work with GPT-5.6

GPT-6 Astra, announced by OpenAI on 3 September 2026 (US time), is a flagship tuned for computer use and long, multi-step work, true to the pitch that it "can do anything a person can do on a computer." It scores 72.6% on OSWorld 2.0, and time per task drops 47% from GPT-5.6 Sol's roughly 75 minutes to roughly 40. This article checks what changed against the benchmarks, then lays out where each ChatGPT plan can use it (Pro at ¥16,800 / ¥30,000, Business and Enterprise get "GPT-6 Pro" in Chat; Plus at ¥3,000 gets it through ChatGPT Work and Codex; Free and Go do not), the caps such as 50 or 200 messages a week, API pricing ($10 input / $50 output, 2.5x Sol) and how to split work with Sol, Terra and Luna, and the behaviour changes on switching (more clarifying questions, more sensitivity to skill files), based on OpenAI's announcement, Help Center and model page.

CLI and Programming Study in the Age of AI Coding Agents [August 2026]: 11 Services, Starting from the Terminal and Git

With Claude Code, Codex and Cursor in everyday use by 2026, what you need is no longer the ability to write from scratch but the ability to read the diffs an agent produces, interpret its errors and recover a broken state — and all of that happens in the terminal. This article compares 11 learning services — WebTerm, WebTerm Learn, Progate, dotinstall, paiza Learning, ZEN Study, Techpit, Recursion, Boot.dev, KodeKloud and DeepLearning.AI — by entry point (language or environment), format, language support, free tier and price. It also covers the courses rebuilt around agents, including Progate's Claude Code Introduction (beta), KodeKloud's Claude Code For Beginners (8h32m) and DeepLearning.AI's course co-produced with Anthropic, and lays out an order to learn in: environment, syntax, agent, evaluation.

11 Programming Learning Services Compared [August 2026]: Choosing by Purpose, Price, End State and Language Support

Lists of thirty "best programming learning sites" mix free services with schools costing thousands of dollars, which makes them useless for deciding. This article narrows the field to 11 services you can study on independently for a few thousand yen a month — Progate, dotinstall, paiza Learning, ZEN Study, Techpit, Recursion, WebTerm, WebTerm Learn, Boot.dev, KodeKloud and DeepLearning.AI — organized by purpose: getting hired, finishing a first course, having something to build, breaking a plateau, and moving into infrastructure. It compares end state, format, language support, free tier and yearly cost, then sets out a study order that working people can sustain and what the foundation needs to contain in the age of AI coding agents.
