Open Weights Flooded the Frontier — and the Price War Went Structural
Open weights flooded the frontier this week — Qwen3.8-Max became the first Max-class model ever open-weighted and Qwen3.8-27B dropped two days later — while the price war went structural in both directions: Anthropic locked Sonnet 5 at $2/$10, and DeepSeek went GA raising prices up to 1,100%. The cheap-model premise we've run this directory on is dead; Grok 4.6 at $2/$6 is its replacement.

Conditional
Launched Aug 12 at $2/$6 with a 61 AA Intelligence Index (ties GPT-5.6 Sol, trails only Fable 5 Max) and leading GDPVal-AA — a day-one launch with a single independent evaluator, so conditional rather than recommended.
Conditional
Open weights shipped Aug 14 under Apache 2.0 with 262K native context and single-GPU deployment; vendor-claimed coding/agent gains await independent reproduction.
Acquired
SpaceX formally closed its $60B Cursor acquisition on Aug 15; the conditional verdict holds.

Our take: Two years of "AI gets cheaper every month" inverted in one week. Anthropic locked Sonnet 5 at $2/$10 to defend share, and OpenAI had already cut Luna 80% — but DeepSeek, the lab that invented the cheap-frontier premise, raised API prices up to 1,100% at GA with peak/off-peak billing. Meanwhile open weights became genuinely competitive with closed models: Qwen3.8-Max shipped the first Max-class open release, and GLM-5.3 staged its weights behind a ~2-week safety gate. We tested none of this week's new models — Grok 4.6 and Qwen3.8-27B land at conditional because their benchmarks are day-one and thin. Read a rate card, not a headline.
