Max plan: lower quality model used in the background

[achimstruve]

I enabled Telemetry and it shows me the following output in the console:

model: 'claude-3-5-haiku-20241022'

even though I am on the max plan and it says below the console Approaching usage limit · resets at 6pm.

This would imply for me that in the background it is not using 4-sonnet, but a lower tier model even though usage limits have not been reached yet. Is that true?

These are my Telemetry related environmental variables:

    "CLAUDE_CODE_ENABLE_TELEMETRY": "1",
    "OTEL_METRICS_EXPORTER": "console",
    "OTEL_METRICS_INCLUDE_SESSION_ID": "false",
    "OTEL_METRICS_INCLUDE_VERSION": "false",
    "OTEL_METRICS_INCLUDE_ACCOUNT_UUID": "false",
    "OTEL_METRIC_EXPORT_INTERVAL": "60000"

Hi! We use both Opus/Sonnet (depending on your settings) and Haiku. We use the latter for a number of background processes. The main conversation always uses your configured model, and not Haiku.
