trimReplayDanglingAssistantToolCalls only collected tool results that
immediately followed the assistant tool-call message. Models such as
gpt-5.3-codex-spark may emit the function_call item before the
explanation text within one response, so history replay order becomes
assistant[tool_call] -> assistant[text] -> tool[result]. The call was
misjudged as dangling and stripped while the tool result survived,
producing a function_call_output without a matching function_call that
the Responses API rejects with 400.
- widen the response collection window to skip interleaved plain
assistant text messages, and drop orphan tool results in the same pass
- synthesize a placeholder function_call (or drop the output when the
tool name is unknown) in normalizeOpenAIResponsesInput so conversations
already persisted with corrupted history can resume
Route the MiniMax OpenAI-compatible endpoint (global api.minimax.io and
China api.minimaxi.com hosts, plus the MiniMax-M3/MiniMax-M2.7 model ids)
to the thinking_type disable branch so that disabling thinking writes
thinking:{type:"disabled"} and drops reasoning_effort, matching the
existing MiMo/deepseek/glm behavior.
openAIThinkingDisableKind only matched dashscope/qwen/aliyun,
deepseek/bigmodel/z.ai/zhipu, and gpt-5.1+/gpt-6. Xiaomi MiMo
(api.xiaomimimo.com, model mimo-*) fell through to the default
branch, so when a user set reasoning=disabled the adapter wrote
no disable field and MiMo kept thinking enabled (extra latency +
reasoning token cost contrary to user intent).
Add xiaomimimo/mimo to the thinking_type case — MiMo uses the same
thinking:{type:"disabled"} shape as deepseek/glm, confirmed in
MiMo docs.
- openai.go: +2 conditions in openAIThinkingDisableKind
- openai_thinking_disable_test.go: cover MiMo (base/model/ultraspeed),
regress deepseek/glm/z.ai/qwen/gpt-5.1/gpt-6/unknown, and verify
applyOpenAIThinkingDisable writes thinking:{type:disabled} +
deletes reasoning_effort for MiMo
- Deleted outdated test files for OpenAI endpoint functionality.
- Improved the OpenAIEndpointURL function to better handle custom paths and version segments.
- Introduced a new helper function, stripEndpointVersionPrefix, to streamline endpoint processing.
- Introduced a new endpoint option for OpenAI integrations, allowing users to specify a custom path.
- Updated relevant components and validation logic to accommodate the new endpoint.
- Enhanced documentation and error messages to reflect the addition of the custom endpoint option.
