Looks like o1 performance without reasoning. Pretty good but seems reasonable that they didn’t want to call this 5 as they’ve already got a product out there that is as performant.<p>Another notable thing here is a big drop in hallucination rate as measured by their benchmarks (for whatever those are worth).

Insane pricing - $75.00 &#x2F; 1M input tokens &amp; $150.00 &#x2F; 1M output tokens. They mention it&#x27;s a big model but it&#x27;s hard to imagine inferencing costs being 20X higher than 4o.<p>I&#x27;m assuming they&#x27;re doing everything possible to get everyone onto the reasoning models? This seems like it&#x27;s going to be a short lived model.
