Good morning, it's August 26th, and this is Pi Mono.
The dominant story today is provider compatibility. Several independent fixes converged on the same root problem: providers reject requests that don't match their exact expected shape.
Start with tool_choice. PR 8633 and PR 8650, filed independently by different contributors, both fix the same issue: OpenAI's Responses API and xAI's Grok reject requests where tool_choice is set to "none" but no tools are attached. That's exactly what happens during compaction. Commit fe37e9f already fixed this for…
Reasoning deltas got similar treatment. PR 8605 concatenates consecutive OpenAI completions reasoning chunks of the same type, following OpenRouter's own approach, and commit 650e7a6 derives OpenRouter's reasoning controls more accurately, closing issue 8454. Meanwhile PR 8642 addresses Bedrock: OpenAI models hosted…
The second theme is agent robustness under concurrency and abort. PR 8658 fixes a bug where hitting Stop during a running tool call produced two cancellation errors instead of one. Commit 240eb29 fixes message ordering so runtime custom messages no longer land between a tool call and its result, which some providers…
