#AI Models

A 4B model trained for $1,200 cut Postgres query latency 44.7% on a standard benchmark. The trait that made it work, and a routing table for your own tasks.

Qwen's September 18 model takes audio and video natively with 1M context and, by Qwen's own method, cuts per-hour audio cost 98% versus its predecessor.

TypeSafe AI's Jev returns typed values with probabilities, not text, and claims 70 to 500 ms responses. What the vendor figures mean and how to test them.

Compare Fugu Max and Ultra v2 pricing, long-context charges and review costs. Use a workload test to decide when additional reasoning justifies its price.

A dated ledger of AI model releases in September 2026, each row verified against the vendor’s announcement, with price, context and what it replaces.

On August 12, DeepSeek's pricing page listed V4-Pro-0813 with no changelog entry and a homepage saying nothing had changed. GA was announced a day later.

xAI's Grok 4.6 keeps Grok 4.5's headline rates, but the $2/$6 tier only holds below a 200K-token prompt: cross it and the whole request reprices.

Alibaba previewed Qwen3.8-Max at WAIC Shanghai, claiming 2.4 trillion parameters and second only to Fable 5 — yet shipped zero benchmarks to back it.
