# Altworld's Hemmingway-1 Skips the Fluff and Delivers Paste-Ready Messages

> Altworld's 27B fine-tune of Qwen3.8 tops GPT-6 Astra on everyday message writing and reads as human 26 points more often.

# Hemmingway-1 targets paste-ready messages

General chatbots often surround a requested message with introductions, alternatives, and tone notes. Altworld’s [model card](https://huggingface.co/Altworld/Hemmingway-1) presents Hemmingway-1 as a simpler option: ask for a text, email, or reply, and receive the copy itself. The release applies a 27B open-weight model to short, tone-sensitive communication, a common workload that conventional reasoning and coding benchmarks rarely measure.

| Distribution    | Hugging Face weights, quantizations, hosted playground, Mac app, and Android app |

Altworld released the weights alongside a [hosted playground](https://hemmingway.io) and a public [code repository](https://github.com/lukeckprobierts/Hemmingway-1). The Apache-2.0 license permits commercial use, modification, and redistribution subject to its terms.

## Eighty prompts, pairwise judging

Altworld created CommunicationBench from 80 real-world writing requests. For each matchup, a judge model received two shuffled answers to the same prompt without model labels. Altworld says it ran comparisons in both orders and used a judge model distinct from the systems being evaluated, reducing label and ordering bias.

On Altworld’s reported scoring scale, Hemmingway-1 ranks above Fable 5.1 and leads GPT-6 Astra by 50 points. The published chart also places Kimi K3, GLM-5.3, Grok 4.6, and DeepSeek V4 Pro behind it.

Altworld’s CommunicationBench compares responses to 80 everyday writing requests.
