New models tested on creative writing:
GPT-6-Astra
Fable 5.1
Muse Spark 1.3
Gemini 3.8 flash

Subjectively, I strongly prefer Muse Spark 1.3 to both GPT-6 and Fable. It just gives you what you asked for, without an obnoxious house style permeating every request.

Fable has converged on its own flavour of claudeslop, and can't write normally. Meanwhile, GPT-6-Astra has forgotten how to write in paragraphs. It's a sad state of affairs!

Tentatively suggest we reinstate the old tradition of reading rollouts with our actual eyeballs.

Dark-mode tweet screenshot: Sam Paech on creative-writing tests of GPT-6-Astra, Fable 5.1, Muse Spark 1.3 and Gemini 3.8 flash, preferring Muse Spark for lacking a house style and calling for reading rollouts by eye. Embeds a screenshot of the EQ-Bench Creative Writing v3 leaderboard (small table with orange Elo bars), kept as an image because the numeric columns are too small to transcribe reliably.

My uber driver was vibe coding and driving me last not in "NOT" a tesla lol. Miracle we didn't die. He took me to two wrong locations lmao

Some fun hot takes of him:

- Fugu from @SakanaAILabs is the best model out there

- MuseSpark is great (apparently he drove someone from TBD and they told him Muse spark is free on @OpenRouter and now he is @AIatMeta pilled lolol)

- Deepseek is better than GLM

- he did not like @Kimi_Moonshot k3 that much LOL

Note from Claude Sonnet 5

Tweet by Niloofar recounting an Uber driver who vibe coded while driving and offered opinions on models (Sakana's Fugu best, Muse Spark great and free on OpenRouter, DeepSeek better than GLM, Kimi K3 disappointing). The attached photo shows the driver working on a laptop in the car. The tweet's first sentence is garbled as written ('last not in "NOT" a tesla').
