| $5 for 1million tokens in $25 for 1million tokens out

|
| On-topic, I love the fact that Opus is now three times cheaper. I
| hope it's available in Claude Code with the Pro subscription.
|
| EDIT: Apparently it's not available in Claude Code with the Pro
| subscription, but you can add funds to your Claude wallet and use
| Opus with pay-as-you-go. This is going to be really nice to use
| Opus for planning and Sonnet for implementation with the Pro
| subscription.
|
| However, I noticed that the previously-there option of "use Opus
| for planning and Sonnet for implementation" isn't there in Claude
| Code with this setup any more. Hopefully they'll implement it
| soon, as that would be the best of both worlds.
|
| EDIT 2: Apparently you can use `/model opusplan` to get Opus in
| planning mode. However, it says "Uses your extra balance", and
| it's not clear whether it means it uses the balance just in
| planning mode, or also in execution mode. I don't want it to use
| my balance when I've got a subscription, I'll have to try it and
| see.
|
| EDIT 3: It _looks_ like Sonnet also consumes credits in this
| mode. I had it make some simple CSS changes to a single HTML file
| with Opusplan, and it cost me $0.95 (way too much, in my
| opinion). I 'll try manually switching between Opus for the plan

| selecting a different element or re-selecting?" instead of
| fabricating a description.
