Kaeso 0.5.2

Claude Code and Codex reach more models, and fresh installs start with KPMR data as of 2 November 2026.

Highlights

• Unsupported efforts left out. Claude Code and Codex work with models that list no effort levels or don't reason, instead of failing with an error. #580
• Current models and prices. A fresh install starts with KPMR's models and prices as of 2 November 2026, and four DeepSeek models now refuse JSON schemas before sending. #581

Changed

• Gateway: A fresh install starts with KPMR's models and prices as of 2 November 2026, which add OpenRouter's openai/gpt-5.2-chat and update several OpenRouter prices and limits. deepseek-flash, deepseek-v4-pro, deepseek-v4-flash and deepseek-v4-flash-vision-exp no longer list structured output, so Kaeso refuses a JSON schema for them before sending and names response_format, while JSON mode (json_object) works as before. Running installs get the same data from KPMR on their own. #581

Fixed

• Claude Code and Codex now reach models that list no effort levels or don't reason. Kaeso leaves out the effort (output_config.effort, reasoning.effort or reasoning_effort) or adaptive thinking that the model cannot use, and names it in the kaeso-left-out header. An effort outside the model's levels, and enabled thinking or a budget for a non-reasoning model, are still refused. #580
