Both ``.opencode/models/default.txt`` (the agent default model when
no tier slot is specified) and the tier-0 entry in
``.opencode/models/tiers.yaml`` were pointing at OpenAI's GPT-5
family (gpt-5-mini and gpt-5-nano respectively). Rebinds to
``local-claude/claude-haiku-4-5`` to keep the default workload on
the local proxy at the per-million rate:
$1 in / $5 out / $0.10 cached (Haiku 4.5)
versus
$0.25 in / $2.00 out / $0.025 cached (gpt-5-mini)
$0.05 in / $0.40 out / $0.005 cached (gpt-5-nano)
Haiku-4-5 is more expensive per-token but Anthropic's prompt
caching (90% off cached input) typically wins for workloads with
large repeated system prompts — which the auto-agents pipeline
absolutely has. The actual cost/PR comparison will be visible
once a few cycles have run through the now-functional cost
dashboard (telemetry commit 62d4e8f07).
No code changes — pure configuration. Revert is one-line if the
observed cost profile favours the OpenAI defaults.
