Miller: Frontier AI models can now handle vague, open-ended autonomous prompts
“And seeing how Fable five and GPT 5.6 and that level model is reacting to that vague flavor of prompt. Like you could, you couldn't do this a year ago. Now you absolutely can.”
Wolf: GPT-5.6 and Mythos Exhibit Distinctly Different Frontier Behaviors
“But also, we can see that both Frontier model and I take GPT, 5.6 and Mythos doesn't seem to have at all the same type of behaviors. So there is differences here in the effect of, you know, they are not trained exactly the same way and they don't behave the sa…”
Calacanis: Moonshot's Kimi K3 matches GPT 5.6 at half the cost
“China's moonshot AI released Kimi K three. Open source model, obviously. Performance on par. On par. Not six months behind, not 12 months behind, but now on par with models like Opus 4.8 and GPT 5.6. Which in and of itself is extraordinary, but about 50% cheap…”
Roy: Kimi K3 is 40% cheaper than GPT-5.6 and 70% cheaper than Fable
“Three dollars per million token input, 15 dollars output. It's 40% cheaper than GPT, 5.6, 70% cheaper than Fable.”
Isenberg: Grok 4.5 designs better landing pages than GPT-5.6
“I mean, they're getting so good, but I, you know, based on these two landing pages, I will say I do prefer the grok 4.5 landing page from a design and copy perspective, but they're both pretty excellent.”
Shipper: GPT-5.6 with Codex is best model for knowledge work
“Codex with five, six, which I find to be the most usable, most powerful, fastest model for, specifically for knowledge work and for coding, but like specifically for knowledge work”
Shipper: Advanced AI models enable non-engineers to fine-tune models
“Five, six and fabled some extent if you can get around the guardrails is makes it easier, easy enough to make a machine learning pipeline and run it that, and that's everything from like grabbing the data to making, like making more synthetic data to like actu…”
Dan Shipper: GPT-5.6 Accurately Handles 90% of Routine Emails
“I think that five five was fine, but not quite good enough. Like, I would say generally the email responses here, so like this email draft, for example, is like, It's as if I wrote it, like it's, maybe there's something that I would slightly change, and I migh…”
Shipper: Rates GPT-5.6 Design Skills a B, Up from C or D
“This is another nice thing about 5.6 that's pretty new is, it does this like design checkpoint. So it's really, they're trying to make it better at design, and I think it's not, Perfect. Like it always wants to do warm paper backgrounds for some reason. I don'…”
OpenAI's GPT-5.6 Preview Costs Half as Much as Anthropic's Fable
“And actually the preview of GPT, 5.6 is about half the cost of the of Fable.”
OpenAI GPT-5.6 Matches Anthropic Mythos on Exploit Bench at Double Efficiency
“So they ran GPT, 5.6 through a test called exploit bench and the cap, the capabilities were basically on par with mythos. And this is obviously a cybersecurity test, but mythos is much less token efficient. So mythos do something like 300,000 tokens for the fo…”
Hays: GPT-5.6 access is restricted to 20 companies by US government
“Of course by US government directive, access is limited to only 20 pre-approved companies.”
Hays: OpenAI GPT-5.6 spans Sol, Terra, and Luna tiers
“To go back to your other question, so Sol is the frontier model, Terra is a balanced model for efficient everyday work, and then Luna is a fast and affordable model for high volume work.”
