Here is a trend I'm noticing: - GPT-5 mini costs $0.25/$2 and will be discontinued in December. - GPT-5.4 mini costs $0.75/$4.5 and is supposed to be the replacement. - GPT-5.4 nano costs $0.2/$1.25 and, while it ranks better in benchmarks than GPT-5 mini, it's not even close when you test it in real scenarios. So you're left being forced to go to GPT 5.4 mini if you use 5 mini today. The same thing is happening here…

who tf would use mini when you have dsv4 flash

Waiting for @simonw to report on this, before I read and try it

I would love to see a more descriptive review from simonw instead of just SVGs generations.

I try! https://simonwillison.net/2026/Jun/9/claude-fable-5/ and https://simonwillison.net/2026/Jun/11/fable-is-relentlessly-...

I'm excited for GPT-5.7 Pneumonoultramicroscopicsilicovolcanoconiosis, hope they drop it soon

GPT-5.8 Llanfairpwllgwyngyll

You mean Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch ?

We need more coding benchmark score. Not sure that winning terminalbench 2.1 alone is a clear win over Fable/Mythos yet.

But they are the only ones who can benchmark, so the best and only benchmark will be the one where they win. It's just business baby.

discontinuing the cheaper options is a risky move for openai

will trigger re-evaluations of models by other labs + inference providers

But you have multiple providers, not just one.

And every single one of those providers would buckle under government pressure. Fable itself is hosted on all major cloud providers. How many offer it today?

The providers on OpenRouter are not all in the US.

When will GPT-5.6 Protomolecule drop? Me and the boys on Eros can't wait to get our hands on it!

I'm excited for GPT-5.7 Pneumonoultramicroscopicsilicovolcanoconiosis, hope they drop it soon

For me, it's GPT-5.9 Year of the Whisper-Quiet Maytag Dishmaster

I think GPT writes code the best. How well will it write in version 5.6? It gives me chills. Recently, I went head-to-head with GPT on nearly 2,000 lines of code, and GPT's solution was superior and faster. I even referenced multiple codebases on GitHub while trying, but they were incomparable to GPT. So using GPT brings both fear and excitement. The fear comes from realizing that this level of code is now the averag…

How do you judge what is a good or bad thing to learn from a LLM? So you don't have to unlearn the bad bits later

When I searched for papers on using LLMs, I found that typically, you can have an LLM generate code and then ask it to find GitHub projects similar to that code. Then you can learn by looking at the pull requests and seeing how they structure things In the old days, if I wanted to understand why memory offsets, padding techniques, or data layout structures were written a certain way, I had to stare at a senior programmer's code all day or wait for them to reply. But LLMs, while they do flatter me, explain things at a level I can actually understand. And LLMs don't get annoyed.

If you have no need for Anthropic/OpenAI's frontier model capability, you may be better served with an open-weight model that can't be taken away. Edit: > GPT-5 does the job. I bring up DeepSeek V4 Flash a lot on HN, but I want to mention that according to Artificial Analysis, it trades blows with GPT-5 (high) (from August, 2025) [0] [0]: https://artificialanalysis.ai/models/comparisons/deepseek-v4...

Unless you are hosting it yourself on your own infrastructure it absolutely can be taken away.

For all intents and purposes you'll be able to move an open weight model wherever you want.

I really dislike this rhetoric, you sound like the FSF guys who are like "you're not free until you're running coreboot with zero binary blobs". Sure they have a point but also, most people are fine running regular linux.
