DesireCore v10.0.161

Release Date: 2026-09-14

New Features

• Added “Creation Time” sorting to manual sessions: The Organize menu in the manual multi-session sidebar now includes a “Creation Time” sort option, and sessions are sorted by creation time by default. Unread messages no longer change topic positions.
• Added support for the DeepSeek V4.1 Flash model: The Compute Service model library now includes DeepSeek V4.1 Flash and alias specs, making it easier for users to connect and use.

Fixes

• Fixed an issue where enabling thinking for newer models such as Claude Opus 4.7 and later, Sonnet 5, and Fable 5.1 was rejected with a 400 error when connecting directly to Anthropic’s official API or a third-party relay using an API key. Thinking parameters are now automatically rewritten according to the adaptive generation.
• Fixed an issue where models such as Claude Opus 4.7 and later, Sonnet 5, and Fable / Mythos were rejected with a 400 error by Anthropic because temperature, top_p, top_k, or forced tool selection were automatically included. Rejected sampling parameters are now automatically removed, and tool selection is downgraded or normalized when making requests.
• Fixed an issue where the Claude subscription compatibility precheck misidentified models such as claude-opus-5 that omit thinking parameters as unknown models and returned a 400 error.

Improvements

• Unified Anthropic model generation identification rules. Model ID formats such as underscores, dots, date suffixes, and Vertex prefixes are now supported more reliably, reducing inconsistencies across features.
