2026.10.09.1

Overview

This release adds a ready-made preset for Opper, an EU-hosted AI gateway, so you can connect it by pasting an API key. The Decisions endpoint is now also available at /v1/systemone, so clients built for the upstream System One protocol work with Plexus without changes. Requests that are too large for a model are now reported clearly as context overflow errors.

✨ New Features

• Opper provider preset: Opper now appears in the "Start from a preset" picker when adding a provider. Opper gives you access to 700+ models from 50+ providers through one API and one key. The preset fills in the chat, messages, and responses endpoints and supports model discovery, so setup only needs your API key. (#983) @Felixkw12
• /v1/systemone endpoint alias: Decisions requests can now be sent to /v1/systemone as well as /v1/decisions. This matches the System One protocol name used upstream. Both paths use the same authentication, quotas, routing, and usage tracking, and existing /v1/decisions clients keep working. (#980) @khangkontum

🐛 Bug Fixes

• Requests that are too large for the target model are now reported as context overflow errors instead of generic failures, so it's easier to see what went wrong. (#984)
