Big sigh a relief from Spurs fans tonight. Whew. This team is well coached. Love seeing Dylan Harper show up just when he’s needed. Steph Castle great too. 🏀

If the announcers say that Wemby is out one more time I’m going to lose my mind. Yes, we know! 🏀

Tonight UT is remembering staff and faculty who have passed away by darkening the tower except for two rings of lights near the top. We sat for a while and listened to the bells.

I’ve been trying to find the right balance of AI models to use in Micro.blog. Currently we use a few different flavors of GPT, including OpenAI’s cheaper “flex” version when speed doesn’t matter much, such as in the background work that powers Inkwell’s Reading Recap feature.

API pricing is a little all over the map, so I thought I’d capture some of the recent prices here, for OpenAI and Anthropic. I’m including a couple older models too, like the retired GPT-4.5. This is per million tokens, input / output.

GPT-5.5:      $5.00 / $30
GPT-5.4:      $2.50 / $15
GPT-5.4 Mini: $0.75 / $4.50
GPT-5.4 Nano: $0.20 / $1.25
GPT-5:        $1.25 / $10
GPT-4.5:     $75.00 / $150
Opus 4.7:     $5.00 / $25
Opus 4.6:     $5.00 / $25
Opus 4:      $15.00 / $75
Sonnet 4.6:   $3.00 / $15
Haiku 4.5:    $1.00 / $5

What can we learn from this? I have no idea. Clearly GPT-4.5 was a gigantic model, and so OpenAI changed course into more efficient models. Opus has generally been more expensive, but now is comparable to GPT-5.5.

Marked-up Mac minis on Ebay, going for almost $1k… Nutty. Better to just get a MacBook Neo.
