feat(studio): read OpenAI-compatible span payloads as a conversation#2028rrhyne wants to merge 1 commit into
Conversation
Detect a payload that carries chat turns — a bare transcript, a request
(`messages`, including one recorded as an HTTP body under `content`), or a
response (`choices[].message`, `assistant_message`) — and open it in a new
`chat` format alongside raw, md, and json.
User and assistant turns render as bubbles with markdown bodies. The context
around them starts folded away in native <details>: system and developer
prompts, tool results, assistant reasoning, and each tool call's arguments.
Detection is strict enough that a payload like {"message": "some prose"}
stays JSON: request turns must name a role, and a response message, whose role
is implied by position, must carry content, reasoning, or a tool call.

- Around line 137-149: Update the response parsing around responseMessages and

site:platform.openai.com/docs/api-reference/chat/create-chat-completion n choices alternative completions Chat Completions API
💡 Result:
The n parameter in the OpenAI Chat Completions API is used to specify the number of chat completion choices to generate for each input message prompt. When this parameter is set to an integer greater than 1, the API will return multiple distinct completions [1]. Each of these completions is returned within the choices array of the response object, allowing you to programmatically select or display different generated outputs for the same conversation context. Note that requesting multiple choices consumes token limits and costs based on the total number of tokens generated across all choices [1].

Do not render alternative choices as consecutive turns.
When root.choices contains multiple choices, responseMessages creates one ChatMessage per choice, and SpanPayloadChatView renders each as a separate turn. Since n > 1 returns alternative completions, select one documented choice or preserve choice boundaries. Add an n: 2 regression test.

Assemble recorded streaming chunks before transcript parsing.
AgentMonitorRoute records streamed output as an array of objects containing choices[].delta. toTranscript treats this array as messages, but each chunk lacks a top-level role, so toMessage rejects it and toChatMessages returns null. Group chunks by choice index and concatenate their content, reasoning, and tool-call arguments before building messages.

Summary
Span input/output payloads that hold an OpenAI-compatible conversation now open in a new
chatformat, which renders the payload as the exchange it describes instead of a wall of JSON. It joins the existingraw,md, andjsonoptions on the payload toggle and becomes the default when — and only when — the payload really is a conversation. Before, reading what a user asked and what the model answered meant scrolling a pretty-printed request with a multi-thousand-character system prompt at the top.Changes
openaiChat.ts(new): decides what counts as a conversation and normalizes it toChatMessage[]. Accepts a bare transcript, a request (messages, including one recorded as an HTTP body where the request sits undercontent), and a response (choices[].message,choices[].delta,assistant_message). A payload holding a request and its reply reads as one conversation ending in the answer. Handles string,null, and multi-part array content,reasoning_content, and tool calls in both the nested (function.name) and flattened spellings.{"message": "some prose"}stays JSON: request-side turns must name arole, one stray element rejects an array, and a response-side message — whose role is implied by position — must carry content, reasoning, or a tool call.SpanPayloadChatView.tsx(new): user and assistant turns as bubbles with markdown bodies. System and developer prompts, tool results, assistant reasoning, and each tool call's arguments start folded away in native<details>, so the exchange is what the section shows and the context is one click away.spanPayloadFormat.ts:'chat'joins the format union;autoFormatprefers it;readPayloadFormatsreports both capabilities from a single parse, replacing the now-unusedisJsonPayload.SpanPayloadFormatToggle.tsx: achatbutton, disabled with its own tooltip reason for payloads that are not a conversation.SpanPayloadView.tsx: renders the chat view, and falls back to the default when a caller asks forchaton a payload that cannot support it — the same guardjsonalready had.IntakeDetail/README.md: documents the fourth format and the detection rules.Type of Change
