From 9b67a2b1dd21b71cb275491cc10cdec133002bf7 Mon Sep 17 00:00:00 2001 From: 404oops Date: Thu, 27 Aug 2026 00:08:02 +0200 Subject: [PATCH 01/14] Add AI response normalization controls Introduces a new `normalize` option for chat completions, plus release-date based default normalization (post-2026-09-01) to coerce provider-native outputs into a consistent OpenAI-style shape. Adds shared normalization utilities, extensive driver/provider consistency tests, and controller safeguards that pin provider-native output where route-specific translators are used. Also wires the option through puter.js (`chat` options and `puter.ai.normalize` default), updates AI/chat response docs and examples, and resolves related TypeScript typing issues reflected in the typecheck baseline. --- .../puterai/PuterAIController.test.ts | 6 + .../controllers/puterai/PuterAIController.ts | 10 + src/backend/core/context.ts | 5 + .../ai-chat/ChatCompletionDriver.test.ts | 286 ++++++++ .../drivers/ai-chat/ChatCompletionDriver.ts | 48 +- .../drivers/ai-chat/providers/ChatProvider.ts | 3 + .../ai-chat/providers/FakeChatProvider.ts | 11 +- .../providers/azure/AzureChatProvider.ts | 2 +- .../providers/azure/AzureResponsesProvider.ts | 4 +- .../providers/claude/ClaudeProvider.ts | 2 +- .../ai-chat/providers/groq/GroqAIProvider.ts | 2 +- .../providers/mistral/MistralAiProvider.ts | 75 ++- .../moonshot/MoonshotProvider.test.ts | 3 +- .../providers/ollama/OllamaProvider.ts | 8 +- .../openai/OpenAiChatCompletionsProvider.ts | 2 +- .../openai/OpenAiChatResponsesProvider.ts | 6 +- .../openrouter/OpenRouterProvider.ts | 5 +- .../providers/providerConsistency.test.ts | 632 ++++++++++++++++++ .../providers/together/TogetherAIProvider.ts | 2 +- src/backend/drivers/ai-chat/types.ts | 16 +- .../drivers/ai-chat/utils/OpenAIUtil.js | 25 +- .../drivers/ai-chat/utils/compaction.js | 23 +- .../ai-chat/utils/modelRouting.test.ts | 1 + .../ai-chat/utils/normalizeToOpenAI.test.ts | 277 ++++++++ .../ai-chat/utils/normalizeToOpenAI.ts | 183 +++++ src/backend/drivers/ai-ocr/OCRDriver.ts | 6 +- .../ai-speech2speech/VoiceChangerDriver.ts | 3 +- .../openai/OpenAISpeechToTextProvider.ts | 4 +- .../providers/xai/XAISpeechToTextProvider.ts | 6 +- src/backend/drivers/ai-tts/TTSDriver.ts | 18 +- src/docs/src/AI/chat.md | 38 +- src/docs/src/Objects/chatresponse.md | 16 +- .../examples/ai-claude-cache-control.html | 4 +- src/puter-js/src/modules/ai/ai.test.js | 41 ++ src/puter-js/src/modules/ai/chat.js | 11 + src/puter-js/src/modules/ai/index.js | 12 + src/puter-js/src/modules/ai/types.js | 9 + src/puter-js/tests/api/suites/ai.suite.ts | 24 + tools/typecheck-baseline.json | 31 - 39 files changed, 1756 insertions(+), 104 deletions(-) create mode 100644 src/backend/drivers/ai-chat/providers/providerConsistency.test.ts create mode 100644 src/backend/drivers/ai-chat/utils/normalizeToOpenAI.test.ts create mode 100644 src/backend/drivers/ai-chat/utils/normalizeToOpenAI.ts diff --git a/src/backend/controllers/puterai/PuterAIController.test.ts b/src/backend/controllers/puterai/PuterAIController.test.ts index 321a33e5c..d87445416 100644 --- a/src/backend/controllers/puterai/PuterAIController.test.ts +++ b/src/backend/controllers/puterai/PuterAIController.test.ts @@ -369,6 +369,9 @@ describe('PuterAIController.openaiChatCompletions', () => { ]);

Reasoning replay. The coercer dropped Anthropic thinking-block signatures and the Responses handler dropped reasoning item ids/encrypted_content, so a normalized reasoning turn could not be replayed — Anthropic rejects an extended-thinking tool-use continuation whose thinking blocks lost their signature. Both now ride `message.reasoning_details` verbatim, and both input paths accept them back: ClaudeProvider splices the blocks ahead of the content (Anthropic requires them to lead), and the Responses input processor expands them into standalone `reasoning` items. Output-only fields a replayed message carries (`reasoning`, `refusal`, `normalized`) are stripped on both paths, since neither upstream accepts them. The docs caveat recommending `normalize: false` for agentic Claude loops is gone; it is no longer true. Unmapped stop reasons. chatresponse.md promised a vendor `finish_reason` with no OpenAI analog "passes through unchanged" — true for the Mistral remap, false for the Anthropic coercer, which discarded it. Anthropic's `pause_turn` means "continue this turn", so flattening it to `stop` destroyed the signal. The coercer now passes unmapped values through verbatim, matching both the doc and the Mistral path, and the docs gain the full Anthropic stop-reason table. Reasoning summaries. Multi-part summaries joined with '' instead of a blank line, and the streaming Responses path emitted no reasoning at all; `response.reasoning_summary_text.delta` now feeds the same `reasoning` stream channel the chat-completions handler uses. Types. `text?: string & { verbosity?: ... }` was an uninhabitable intersection (providers read `text?.verbosity` as an object), and the verbosity enum was `'concise' | 'detailed'` where OpenAI accepts `'low' | 'medium' | 'high'`. Adds `reasoning`, `reasoning_details`, and `refusal` to the SDK ChatMessage typedef.

The camelCase remap did not touch it, so a non-streamed magistral response reached the caller as an array with no `reasoning` — the one case left where a provider did not produce the equalized shape this branch promises. Streaming had the matching bug: the chunk array was handed to addText, which would have stringified it into the text stream. Both paths now split chunked content into a string `content` plus a `reasoning` string, joining multiple thinking chunks with a blank line as the Responses handler and the Anthropic coercer do. The streaming fix rides the existing Mistral-only `chunk_but_like_actually` hook, so no new deviation is introduced. The conformance matrix had no Mistral reasoning fixture, which is why it missed this; it now has one carrying chunked content, verified to fail without the flattening.

Gate the Mistral dialect remap. The camelCase→snake_case rewrite and the chunked-content flattening were firing for every Mistral call regardless of `normalize` or the cutoff, deleting `finishReason` and `message.toolCalls` out from under any caller reading them. Both now sit behind the policy resolution the driver already used, extracted as `shouldPresentAsOpenAI` so the provider and the driver cannot drift. The streaming chunk-array split stays ungated: handing an array to `addText` is a plain bug, and streamed chunks are provider-uniform by design. The conformance matrix now passes `normalize: true`, which is the contract it was always testing. Unify the reasoning join. Three code paths produced two separators while one doc sentence described them all: the coercer joined thinking segments with '', the Responses handler and Mistral with '\n\n'. The coercer now matches, and chatresponse.md's claim is true for every path it covers. Text blocks still join with '' — Anthropic splits prose mid-sentence across them. finish_reason is an open set. chat.md's normalize bullet and the SDK ChatMessage typedef still declared a closed four-value set, contradicting the documented pass-through of unmapped vendor reasons and the coercer that implements it. Stop mutating caller messages. Both reasoning-replay input paths deleted output-only fields from the caller's own message objects, which the driver reuses across fallback attempts. Both strip a copy now; tests pass a frozen message through each. Drop three dead things the type cleanup left: the no-op ChatProvider checkModeration stub (no subclasses, no callers — its removal restores a pre-existing baselined TS2420), the redundant second normalizeReasoningContent call in BytePlus and ZAI, and the coercer's bare-string branch that no provider reaches. A bare string now passes through by reference instead of being coerced.

The driver stamped it on both the OpenAI-shape path and the legacy `response.normalize` path, which converts toward Anthropic blocks — so a caller could get `normalized: true` alongside array content, and the flag told them nothing they could branch on. The legacy branch no longer sets it. That branch is reachable only by a direct driver call with `response.normalize` and no `normalize`; the four wire routes pin `normalize: false`, which skips it. Mistral streaming, split by concern. Flattening a reasoning model's chunked `delta.content` to a string is a correctness floor and stays ungated — the shared handler passes the value straight to `addText`, so an array reaches the caller as stringified objects. Splitting the thinking text out into a `reasoning` delta is the dialect change and now sits behind the policy gate like the non-streaming remap. On the native path the thinking text is kept inline rather than dropped. Mistral `finishReason` is deleted only once its value carried over. The delete ran unconditionally, so a non-string `finishReason` with no `finish_reason` left the choice with no finish reason at all. Four doc claims corrected against the code paths they cover: `content` is string-or-null on normalized responses (tool-only turns carry no text, and the `// always a string` example comment was wrong); `reasoning_details` is not scoped to normalized responses, since Responses models emit it either way; and the release-date rule depends on the serving provider's own dates — OpenRouter derives them from its live API, so models newly listed there from 2026-09-01 normalize by default. Adds the test the copy-on-write fix was actually for: one messages array sent through two sequential calls, asserting the caller's array is untouched and both attempts carried the thinking signature. That is the fallback hazard; the harness wires one provider per model, so the fallback loop itself cannot be driven from a provider test.

Ten findings were put through independent skeptics first; six did not survive — pre-existing on main, inert, or resting on a false premise — and are not acted on here. Mistral streamed thinking now goes to `reasoning` on every path. The previous commit gated the split, which made this the only place in the repo where chain-of-thought reached the visible text channel, and made Mistral the only provider whose streamed chunk *types* depend on a response-format flag. Every other reasoning path routes thinking to `reasoning` unconditionally — ClaudeProvider's thinking_delta, the DeepSeek/OpenRouter rename, and this branch's own Responses summary-delta handler. Removing the gate restores that uniformity and makes the documented promise that streaming is unaffected by normalization true again; the two opposing tests collapse into one that runs the same fixture with and without `normalize` and asserts identical event streams. Docs stop claiming older models are unchanged. Four reasoning fields were made consistent across all models, ungated, and one of them removes a field: on non-streaming responses `message.reasoning_content` is now `message.reasoning`. chat.md gains a table naming all four so a caller reading `reasoning_content` learns why it disappeared, instead of reading that nothing changed for them. Adds the driver-level fallback test. Writing it surfaced that the invariant it was meant to assert is false and always was: the driver rewrites string `content` into text blocks in place on the caller's own messages (`normalize_single_message`, pre-existing) before any provider runs. The test now asserts what is true and load-bearing — both attempts receive the same array reference, and the reasoning artifacts survive attempt 1 so attempt 2 can still replay them.

Mistral's chunked thinking shape is requested via `prompt_mode: 'reasoning'`, which the provider previously dropped on the floor: there was no way to even ask for it. `custom.prompt_mode` now forwards to the SDK's `promptMode`, following the BytePlus custom-params precedent. Opt-in rather than a default because the API rejects the mode where the account/model lacks it ('Reasoning prompt mode is not enabled for this model', code 3051) — verified end-to-end: the 3051 travels back through the stack, which also proves the parameter is delivered. The moment Mistral enables the mode, the ThinkChunk content flows into the existing splitter and comes out as `message.reasoning` and `reasoning` stream chunks with no further changes.

This backfills them under four rules: nothing vendor-deprecated, nothing without a price confirmed on the vendor's official pricing page (each entry's source was recorded during review), nothing absent from the live /models listing, and nothing that fails a live routing probe. Added: 46 Alibaba entries (qwen3/3.5/3.7/3.8 families, VL/omni/MT lines, and Model Studio's hosted GLM/DeepSeek/Kimi third-party models) plus 9 dated aliases; OpenAI chat-latest and gpt-4o-2024-11-20 plus 16 snapshot aliases; Gemini gemma-4-31b-it and gemma-4-26b-a4b-it (vendor-documented free tier) plus rolling -latest aliases; Mistral-hosted zai-glm-5-2 and a mistral-medium-3.5 alias; deepseek-v4-flash-vision-exp; glm-5.3-flash. Culled by the rules: 15 vendor-deprecated OpenAI entries (the 3.5/4/4-turbo legacy line, gpt-4o-2024-05-13, o1-pro, four chat-latest predecessors, the 5.x codex line — deprecations page, most shut down 2026-10-23) and dated aliases onto the deprecated o1/o3-mini/o4-mini; qwen3-vl-flash-2025-10-15 (live routing probe returned upstream 400 twice). Tiered Alibaba prices are encoded at the base tier and busy-hour rates where time-of-day priced, noted in comments. Every surviving addition was verified end-to-end through a local deployment: 58/58 answered a live prompt, including all 46 Alibaba entries and every spot-checked alias. Not changed, flagged for maintainers: pre-existing o1, o3-mini and o4-mini entries are now vendor-deprecated (shutdown 2026-10-23); the pre-existing deepseek-v4-flash/-pro prices no longer match DeepSeek's current pricing page; gemma-4 emits its own markup inline in content.
