frontier-models

Grok 4.6, Gemini 3.7 Flash, DeepSeek V4-Pro-0813, and GLM-5.3 shipped within three days of each other — and not one of them is a new base model. The frontier is advancing by post-training, harness, and serving efficiency while every next-generation base stays in the oven.

In twelve days, Chinese labs pushed the capability floor toward zero, Anthropic halved the price of the frontier, and Google cut Flash tokens again. Read together, the fortnight says one thing: the capability premium is over, and margin is the only battleground left. A ledger of who pays.

Within four days in July, Google shipped a model built to find software vulnerabilities and Anthropic shipped one it deliberately held behind its own frontier on cyber. Read together, they turn dangerous capability into a permissioned product — and move the gate from policy to product.

Anthropic shipped Claude Opus 5 as near-frontier intelligence at half the cost of Fable 5. The launch reads as good news for buyers. Read from the P&L, it is a margin admission — the clearest signal yet that the race has moved from raw capability to cost-per-task, and that nobody expects customers to pay the old premium for the top of the curve.

Google's July 21 drop cut Flash token prices 17% and added a security-tuned Cyber variant. The tell is the model that didn't ship: Gemini 3.5 Pro, promised for June, is still partner-only while compute moves to Gemini 4.

Moonshot AI shipped a 2.8-trillion-parameter model it calls the world's first open 3T-class model — while reportedly raising at a $30 billion valuation. The interesting number isn't the parameter count. It's that a startup pitching investors on scarcity gave its best asset away.

Twelve days after a US government review nobody can fully describe, OpenAI's GPT-5.6 Sol went public on July 9. The executive order behind it bans mandatory preclearance in plain text — and the government ran one anyway. This is what happened to the frontier-release regime after the machinery got used a second time.

In eighteen days, Washington turned a model release into a licensed event. Anthropic's Mythos and Fable 5 went dark on a secret Commerce letter, OpenAI shipped GPT-5.6 only to government-approved partners, and by July 1 the curbs lifted. The pre-clearance regime for frontier AI is no longer hypothetical.
