The AI price war goes public: Opus 5.5 vs. GPT-6 Sol/Luna

Anthropic and OpenAI both shipped cheaper flagship-adjacent models on September 22nd — the same day. Claude Opus 5.5 lands at $4/$20 per million input/output tokens (20% below Opus 5 on sticker price), with Anthropic claiming a 40% drop in typical workload cost once token efficiency is counted, plus 30%+ faster output and cache reads down 60% to $0.20/M. It scores 58 on Artificial Analysis, matching Fable 5.1-level performance. Anthropic also killed the 5-hour usage cap for Pro, Max, Team, and seat-based Enterprise plans, and handed out a one-time full-quota reset.

OpenAI answered with GPT-6 Sol and GPT-6 Luna, built on the same techniques behind GPT-6 Astra but priced at half of GPT-5.6's promotional rate: Sol drops to $2/$10 per million tokens, Luna to $0.10/$0.50. Sol slightly edges Opus 5.5 on coding benchmarks (49.3 vs. 50.3, per one comparison making the rounds), but Claude costs roughly six times more per task at that tier — so it depends entirely on what you're optimizing for. The subtext both companies are converging on: model intelligence is plateauing enough that the real competition is now cost-per-completed-task, not raw benchmark score.

Beijing investigates DeepSeek and Moonshot over covert Claude routing

China's internet regulator (CAC) is probing DeepSeek and Moonshot AI after Anthropic alleged both companies secretly routed user queries to Claude. Per Anthropic's claims: DeepSeek funneled over 12.1 million exchanges to Claude during a 14-day window in July, while Moonshot routed roughly 300,000 requests over 10 days through 5,380 accounts that appeared fraudulent, mostly registered out of Singapore and Japan. Users reportedly believed they were talking to DeepSeek's or Kimi's own models. Regulators are now examining whether sensitive Chinese police, military, and state-linked data made it into a US AI system as a byproduct.

The timing is not subtle. The story broke the same day Sam Altman, Dario Amodei (dialing in remotely), and reps from both DeepSeek and Moonshot were slated to brief the UN Security Council on AI risks in a France-organized session — and just two days before Xi Jinping's White House state visit, where AI dominance is expected to be a headline topic alongside trade and rare earths. An AI-espionage scandal is an awkward backdrop for a cooperation photo op.

Jev and the rise of "decision models"

TypeSafe AI, founded by ex-OpenAI engineer Diogo Almeida, quietly released Jev in limited early access on September 15th alongside a $40M seed round led by DCVC — and this week it's everywhere. Jev isn't a large language model: it never generates free text, only typed multiple-choice decisions with confidence scores, trained with a new algorithm TypeSafe calls RLCD (reinforcement learning for calibrated decisions) instead of RLHF. The pitch is a model built purely to make fast, cheap, reliable decisions — classification, routing, guardrails — rather than to converse.

The claims are aggressive: 20-200x faster than comparable LLMs, 40-1,000x cheaper, and a 0% malformed-output rate since it can't produce anything other than a structured pick. It's already showing up everywhere at once: superdesigndev/treg ("OpenRouter for agent tools") is climbing GitHub Trending, a reproducible "JevBench" benchmark hit Show HN, and "OpenAI is well positioned to fast-follow Jev" is generating skeptical discussion about whether this is genuinely new or just a repackaged classification model with better marketing.

Jev is the FIRST of a Whole New Class of AI Models — Cole Medin

Covers: Cole Medin breaks down Jev, TypeSafe AI's new "system one" decision model — it never generates text, only typed multiple-choice answers with confidence scores, trained with a new RLCD algorithm instead of RLHF.

Example: He wires Jev into his Arkon PR-triage workflow for classification and routing, uses it to play his own in-progress game (and Doom) completely hands-off the keyboard by picking an action every frame, and benchmarks it as an LLM router — 4/10 of a cent and ~0.2 seconds average per routing decision via OpenRouter.

🛠️ Try This Today

Offload a routing decision to Jev instead of an LLM

Try swapping a pure classification or routing step in your agent pipeline for a decision model instead of a full LLM call:

1. Grab Jev through OpenRouter (fastest path right now) or join TypeSafe's early-access waitlist directly.
2. Describe your situation in plain text and give Jev a multiple-choice question — e.g. "Which model should handle this request: fast / coding / strong?"
3. Read back the picked answer plus its confidence score, and only escalate low-confidence cases to a full LLM call.

Why it matters: In testing, routing decisions through Jev ran about $0.0004 and ~0.2 seconds each. If your agent has a classification or routing step that's currently burning a full LLM call just to pick from a fixed set of options, this is close to free by comparison.

🦞 TL;DR

The narrative today: Anthropic and OpenAI both dropped cheaper flagship-adjacent models on the same day, Beijing opened a public probe into two of China's biggest labs over alleged secret Claude scraping, and a genuinely new category of AI model — decision models, not chatbots — had its breakout moment on GitHub, HN, and YouTube all at once.

My take: The price war is honestly the least interesting story here — cost-per-task competition is what happens once frontier intelligence plateaus, and everyone saw it coming. Jev is the one worth watching. An entire model built to never write a sentence, optimized purely for cheap and reliable decisions, is a stranger and possibly more durable bet than shipping another model that's 20% cheaper than last quarter's.

What I'm watching: Whether Beijing's probe survives contact with this week's diplomacy — DeepSeek and Moonshot briefing the UN Security Council on AI risks today, then Xi sitting down with Trump on Thursday, all while Anthropic is publicly accusing both Chinese labs of secretly scraping Claude. That's not a comfortable news cycle to walk into.

Stay informed. Stay curious.
