Settings Ver2.7 - Parameter
| Metric | ver2.6 | ver2.7 | | :--- | :--- | :--- | | Profile load time (1000 params) | 420 ms | 95 ms | | Memory per parameter | 128 bytes | 64 bytes | | Concurrent update handling | None | Thread-safe with mutex |
Upgrading to ver2.7 requires careful translation of old settings.
| Old Parameter (ver2.3) | New Parameter (ver2.7) | Conversion Formula |
| :--- | :--- | :--- |
| max_workers = 10 | thread_pool_max = 10 | Direct mapping |
| buffer_chunk = 256 | batch_size_kb = 512 | Multiply by 2 |
| fail_safe = 1 | error_tolerance_2.7 = 3 | Old 1 = New 3 |
| sync_mode = fast | sync_interval_ms = 200 | Undocumented mapping. Use 200ms. | parameter settings ver2.7
Warning: Do not copy-paste old .conf files. Ver2.7 will reject them with a PARSER_LEGACY_TOKEN error. Use the provided migrate_settings.py script included in the ver2.7 distribution.
Seed works as expected. New: Seed-shift (for batch generation) – a delta applied per image. Shift of 1000 creates strong variation; shift of 100 preserves composition but changes lighting/detail. | Metric | ver2
Deterministic mode (disables all non-seed randomness) now actually works across different batch sizes. Useful for A/B testing prompt changes.
Version 2.7 introduces a refined parameter ecosystem that balances power for experts with approachability for newcomers. While the core mechanics (samplers, CFG, steps) remain familiar, subtle shifts in how parameters interact—especially with the updated latent guidance and new preconditioning defaults—demand a fresh look. This review covers every major dial and toggle, their real-world effects, and the pitfalls to avoid. Seed works as expected
To avoid analysis paralysis, we break down the parameter settings ver2.7 into four families: Performance, Stability, Security, and Interoperability.

Cause: In ver2.7, the sync interval must be less than the global health_check_interval. If sync_interval_ms is larger, the master node assumes the worker is frozen.
Fix: Ensure sync_interval_ms ≤ health_check_interval / 2.
