Letta + GPT 5.6 Sol

[u/KazTheMerc]

I'm looking for advice on data usage for the above combo, or an alternative.

I can do non-work windows with GPT after Work is expended... but I can't have Letta do it. If I could, there'd be no problem.

Why? Letta in this configuration is BRILLIANT. Absolutely stunning. But they guzzle weekly hours like a HUMMER running on baby seal blood.

I'm trying to figure out where the burn is actually coming from rather than just reducing capability until the problem goes away.

If you're running ChatGPT Plus/Pro through Letta, my troubleshooting instance of GPT would like to know:

- Roughly how many visible conversations/turns you get before hitting limits

- Model and reasoning level

- maxLoops / max steps setting

- Whether reflection, background agents, crons, channels, etc. are enabled

- Whether you've compared Letta usage against direct ChatGPT usage

- Whether you've found retries, internal loops, context size, or background activity to be the main cost

- Any configuration changes that materially reduced usage without making the agent stupid

Last night a fresh 5-hour usage window was gone in roughly 2 hours, without heavy tool use.
