Weren't there headlines just yesterday that they weren't releasing this due to safety concerns?

API price cuts were obvious once they made their announcement changing how usage is counted. These moves all make sense when you take into account the enterprise market. https://news.ycombinator.com/item?id=49889873

Shots fired, half the price of Opus 5.5.

Wasn't 6 released like last week? I can't keep up anymore.

gradus_ad

Ominous for the industry and investors that token price is becoming the main battleground. Could be Anthropic's rationale for IPOing this year.

If these models are so smart, can't _they_ select the right model for each task?

phpnode

What's driving the increase in release cadence here? We seem to get new models every week or so now, is this RSI?

Aka "we made an oopsie last week and released what should have been called GPT 6 Terra with the name GPT 6 Sol"

Lapalux

It's relentless, isn't it?

> GPT‑6.1 Sol matches GPT‑6 Astra at roughly one-fifth of the cost Astra is a pretty impressive model. Excited to try this.

I love free market competition. We're getting insane advancements every day. I remember when llms used to cost an arm and a leg for decent intelligence

glimshe

This is great. But maybe part of the motivation is that 6-Sol wasn't as good as initially advertised so they needed to tweak it. I felt a clear degradation in quality in some simple refactoring tasks vs 5.6-Sol.

Guys, are we slowing down yet?

I wish they'd list the environmental cost. My employer has an unlimited AI budget so I don't care about using Astra if it's just more profit for OpenAI. I care more if it actually uses 5x more energy.

barrenko

A night of no sleep this one will be.

Starlevel004

Okay, now price cut 6 Sol (and rename it to Terra again).

dcchambers

GPT-6 Sol released a week ago. Shortest model life ever?

iamdelirium

I wonder if releasing this soon sort of validates the rumor that Sol 6 was just the Terra model they bumped up and slashed the price. Then Opus 5.5 caught them off guard and now they're actually releasing the correct sized model.

Looking at the token prices, if this is half as good as 6-Astra for 3D model creation in Blender, it's going to be an absolute game changer. Opus 5.5 is definitely better at coding, but nothing even comes close to 6-Astra for work in 3D graphics...

> Cached input costs just $0.10 per million tokens—95% less than standard input pricing and 50% less than GPT‑6 Sol’s cached input pricing This is the actual big announcement. 50% cheaper cache than GPT-6 Sol will get you far more mileage on Codex.
