New AI models

Real AI models released across the industry in the last 30 days — 2 companies, 2 releases. This is not howfastai.com's own measured data — everywhere else on this site, a number is either a recorded run or a clearly-labelled placeholder from our own tests. Here, specs and pricing are as reported by the vendor or a release tracker, summarized in our own words, sourced on every card, and not independently verified by us.

JevTypeSafe AI
Released Sep 15, 2026

Not a chat model: it returns a fixed-shape decision (a classification plus a confidence score) instead of writing text, aimed at tasks like tool-call routing and structured data extraction rather than open-ended prompts. Reported 20-200x faster and 40-400x cheaper than comparable LLMs on those tasks; $0.042/M input tokens, output cost described as too low to meaningfully measure. Early access via waitlist, no public API yet.

DeepSeek-V4.1-FlashDeepSeek
Released Sep 10, 2026

Smallest model in DeepSeek's new architecture family, with native multimodal (visual) input. 552B total parameters (MoE) using a new causal encoder-decoder design: 8B active parameters for input, 16B for output. KV cache cut to 1/4 the HBM and 1/8 the SSD storage of the previous generation, lowering cache-hit costs. Live now on the DeepSeek API as deepseek-flash (the retired v4-flash and v4-flash-vision-exp IDs route here temporarily); lower pricing than the prior generation, same peak/off-peak split. Open-weight, on Hugging Face.
