Reason: MiniMax text requests need a current default and catalog, and Flash tool continuations must retain separate reasoning content.

Summary

Add the MiniMax text provider to provider registration, environment configuration, and high-level API resolution. Ordinary text and inexpensive-task defaults now select MiniMax-M3.1-Flash; the current catalog contains Flash first and MiniMax-M3, with image-input/tool capabilities. Explicit saved, legacy, and custom model IDs remain valid request selections. Global and China endpoint overrides remain available.

Preserve reasoning_content through non-streaming and streaming responses, high-level tool loops, and transcript replay. Map supported Flash effort controls and reject disabled thinking, unsupported effort, service_tier, and reasoning_split: false. Keep M3 disabled/adaptive thinking behavior. Use the provider's documented catalog without relying on inherited model discovery. Align MiniMax GMI and mission-planning defaults. Image generation remains image-01.

How this was verified

At commit 16f0792996f43eb2a5900ae99572a192d3286719:

  • 28 focused checks passed: 23 MiniMax regressions plus 5 existing provider health regressions. MiniMax coverage includes actual SDK model resolution, HTTP request serialization to a local server, streaming/non-streaming tool continuations and reasoning replay, URL/data-URL image parts, explicit saved/custom model IDs, allowed and rejected effort controls, M3 behavior, and mocked global/China endpoint serialization. Only unrelated provider construction is replaced in the SDK integration cases; model resolution, tool loops, and HTTP transport execute normally.
  • The focused run used already-cached Vitest 2.1.9, an isolated configuration, and credential-free process environment. The repository pins Vitest 5.0.3; this focused run is not a claim that its full pinned suite passed.
  • TypeScript 5.9.3 syntax transpilation reported zero errors for all 10 changed TypeScript files. This is not semantic type checking.
  • git diff --check passed. No live paid inference was performed.

The exact-head upstream CI workflow passed, including dependency installation, build, package-export checks, lint, semantic type checking, tests with coverage, browser tests, the gated test batch, and the release dry run. The initial rollout's test fixture typing error was corrected in the final commit, and this final run passed type checking.

The separate Published source foundation workflow failed before build in its version-selection step with empty selected-version variables. This result is recorded as a remaining CI limitation; no unchanged-base reproduction or all-checks-green claim is made. Full local setup/build remained paused below the workspace's 110 GiB disk threshold; remote CI supplied the full validation. Existing automatic review feedback about broader provider-priority routing, query expansion, and cost metering is not claimed resolved by this rollout update.

Migration notes

No saved model IDs are rewritten. Omitted MiniMax text models now resolve to Flash; specify MiniMax-M3 or another saved/custom ID explicitly to retain that selection.

Checklist

  • Tests cover the changed behavior.
  • Docs are updated.
  • The title follows Conventional Commits.
  • No secrets or private data are included.
  • Every automated review thread is settled.
  • I have read this change and can explain every line.

Summary by Sourcery

Integrate MiniMax M3.1 Flash as a first-class text provider with safe provider-specific resolution and complete reasoning replay across tool workflows.

New Features:

  • Add MiniMax text-provider registration with MiniMax-M3.1-Flash defaults, documented model catalog, regional endpoints, and explicit custom-model support.
  • Preserve MiniMax reasoning content across streaming, non-streaming, tool continuations, and transcript replay.
  • Support MiniMax image-input and tool-capable text requests while retaining image generation through image-01.

Bug Fixes:

  • Prevent unsupported MiniMax thinking, effort, service-tier, and reasoning-splitting options from being sent, and reject embedding requests before network access.
  • Ensure QueryRouter uses provider-specific credentials and endpoints without leaking keys or URLs between vendors.

Enhancements:

  • Align high-level API, GMI, mission-planning, provider detection, and QueryRouter defaults with MiniMax text support.
  • Use the documented MiniMax catalog without inherited model discovery and retain existing explicit saved or custom model selections.

📝 Walkthrough

The change adds an OpenAI-compatible MiniMax provider with model defaults, environment configuration, provider-specific credential routing, thinking controls, reasoning replay, tool-call support, tests, and documentation.

Changes: MiniMax provider support

Layer / File(s) Summary
Implement and register MiniMax provider
src/core/llm/providers/implementations/MiniMaxProvider.ts, src/core/llm/providers/implementations/OpenAIProvider.ts, src/core/llm/providers/AIModelProviderManager.ts
MiniMaxProvider supports model catalogs, thinking controls, validation, embedding rejection, and reasoning content. The provider manager registers the minimax provider.
Configure defaults and provider routing
src/core/config/AgentOSConfig.ts, src/api/runtime/provider-defaults.ts, src/orchestration/planning/ProviderAssignmentEngine.ts, src/orchestration/pipeline/query/*
MiniMax environment settings configure the provider. MiniMax-M3.1-Flash is used for text and cheap-model defaults. Runtime detection and query routing use provider-specific credentials and base URLs. Embedding defaults use OpenAI when MiniMax is selected.
Preserve reasoning across tool calls
src/api/generateText.ts, src/api/streamText.ts, src/api/sessionTranscript.ts, src/core/llm/providers/IProvider.ts
Assistant transcript entries retain MiniMax reasoning text. Streaming and non-streaming tool continuations replay that content.
Validate and document behavior
src/core/llm/providers/__tests__/MiniMaxProvider.test.ts, src/api/runtime/__tests__/provider-defaults.test.ts, src/core/config/__tests__/AgentOSConfig.providers.test.ts, src/orchestration/pipeline/query/__tests__/QueryRouter.provider-keys.test.ts, docs/getting-started/*, docs/QUERY_ROUTER.md, docs/memory/QUERY_ROUTER.md
Tests cover requests, streaming, model selection, thinking controls, tool loops, endpoint handling, credential routing, errors, defaults, and OpenAI compatibility. Documentation describes MiniMax setup, credential resolution, embedding behavior, and detection order.

Merge Risk: ⚪ Minimal · up to 59460

No actionable PR-introduced issue remains in the reviewed changes. The identified credential mismatches predate this change.

Security architecture risk: 🔵 Low · up to 59460

The change generally improves credential separation. A configuration-dependent credential-misdirection weakness predates this PR, while newly retained reasoning is omitted from history-size accounting. The supported exposure is limited, but deployment-specific impact remains uncertain.

Retained concerns

  • Low · reliability · inferred: Newly retained reasoning is replayed to the provider but excluded from transcript token estimation. Large reasoning turns can therefore remain resident and be retransmitted without contributing to the history eviction threshold, weakening per-session resource containment.
Security review details

Security Blast Radius

  • inferred — The supported credential exposure is configuration-dependent and involves credentials available to the hosting process. The traced selectors consume application configuration and environment variables; no path from prompt text alone to endpoint or credential selection was established. Tenant-wide or deployment-wide exposure cannot be determined from the supplied configuration evidence.

Security Findings and Attack Paths

  • observed — The retained finding concerns independent embedding key and endpoint selection. With OpenAI embeddings selected, no explicit overrides, no OpenAI key, and both Gemini and OpenRouter keys present, the selectors choose the Gemini key and an OpenRouter compatibility URL. This condition existed at the merge base. However, QueryRouter passes baseUrl unchanged while the transport reads baseURL, so effective OpenRouter egress is not established; the default OpenAI transport can instead receive the cross-provider key. This remains a legacy security fact rather than a demonstrated PR-introduced or worsened concern.

Trust Boundaries and Controls

  • observed — Provider matching limits accidental forwarding during rerouting, but it cannot prove the provenance of an explicitly supplied secret. Ordinary shared Chat Completions serialization excludes reasoningText; MiniMax deliberately adds it as reasoning_content. Complete behavior across every other fallback serializer remains unverified.

Resilience and Maintainability Implications

  • observed — The inspected continuation path retains tool lookup and approval checks. Completed tool rounds are captured for fallback, later fallback legs stop after a failing leg executes tools, and session commits discard stale appends after reseeding. These controls limit repeated side effects and stale-state mutation; they do not correct omitted reasoning-size accounting.

Hardening Proposals

  • proposed — Resolve provider identity, credential source, and normalized endpoint as one configuration unit. This would address the legacy independent-selection weakness and make trusted explicit overrides distinguishable from automatic fallback.

High-Level Assessment

Reusing OpenAIProvider behind a distinct MiniMax provider ID is the appropriate fit for an OpenAI-compatible endpoint. Configuring generic OpenAI directly would lose MiniMax-specific routing and defaults; a separate transport would duplicate existing functionality.

<issue_to_address>
**MiniMax key sent to attacker host**

When a caller who controls `generateText` options supplies `provider: 'minimax'` and an attacker-controlled `baseUrl`, while `MINIMAX_API_KEY` is configured, `generateText` can resolve `MINIMAX_API_KEY` while accepting a caller-supplied `baseUrl`; the spread passes that URL to `OpenAIProvider`, whose requests send the key in the Authorization header, exposing the credential to the caller's host.

Do not combine an untrusted `baseUrl` with the server's MiniMax key; restrict URLs to trusted MiniMax endpoints or require caller-owned credentials for custom hosts.

<issue_to_address>
**MiniMax costs break budget handling**

When a MiniMax call returns usage or runs under a `SpendBudget`, miniMax inherits OpenAI pricing, which has no MiniMax rates, so `calculateCost`, `estimateCallCostUSD`, and `costOfUsageUSD` return no cost. Callers receive usage without reported cost, budgets reject unpriced calls by default, and cost-limited budgets do not count MiniMax spend.

Add MiniMax pricing support to the cost calculation and budget pricing paths.

Also at `src/core/llm/providers/implementations/MiniMaxProvider.ts:7`.

<issue_to_address>
**MiniMax models disappear from discovery**

When the MiniMax `/models` response contains normal IDs such as `MiniMax-M3` or `MiniMax-M2.7`, `MiniMaxProvider` inherits `OpenAIProvider.refreshAvailableModels`, which filters out MiniMax IDs, leaving the model cache empty. Listings and model-info lookups omit MiniMax models, concurrent lookups repeat `/models` requests, and routing can fall back to the wrong provider.

Override the model refresh/filtering for MiniMax so its model IDs are cached and exposed.

<issue_to_address>
**AgentOS turns target OpenAI**

When an application uses the AgentOS/GMI defaults with `MINIMAX_API_KEY` set and no OpenAI provider, `createAgentOSConfig` still gives GMI the explicit defaults `openai` and `gpt-4o`; with only MiniMax configured, GMI routes its default turns to an unavailable OpenAI provider and the turn fails instead of using MiniMax.

Derive GMI's default provider and model from the configured default provider, including MiniMax.

<issue_to_address>
**Default provider differs by entry point**

When both `MINIMAX_API_KEY` and `OLLAMA_BASE_URL` are set without OpenAI, OpenRouter, or Requesty credentials, both MiniMax and Ollama are marked default, so `AIModelProviderManager.initialize` selects MiniMax first, while direct API auto-detection checks Ollama first. Users get different providers depending on the entry point.

Ensure only the intended provider is marked default, consistently with direct API auto-detection.

<issue_to_address>
**MiniMax models disappear from discovery**

When miniMax’s `/models` response contains its text model IDs, such as `MiniMax-M3` or `MiniMax-M2.7`, `MiniMaxProvider` inherits OpenAI’s model refresh and pricing logic: the refresh filters out MiniMax model IDs, and the pricing resolver consults OpenAI-only prices. The provider therefore exposes no MiniMax models to discovery and returns no calculated usage cost for MiniMax calls.

Add MiniMax-aware model discovery and pricing rather than relying on OpenAI-specific filtering and price data.

Remediation recommended

1. Dollar budgets reject MiniMax calls 🐞 Bug ≡ Correctness
Description
MiniMaxProvider inherits an OpenAI-only pricing table with no MiniMax model rates, and the
spend-budget estimator likewise prices only the OpenAI provider. A MiniMax call with a normal dollar
budget is refused as unpriced unless explicitly allowed; if allowed, its completed cost is not
recorded against that budget.
Code

src/core/llm/providers/implementations/MiniMaxProvider.ts[R6-12]

+export class MiniMaxProvider extends OpenAIProvider {
+  public readonly providerId = 'minimax';
+
+  public override async initialize(config: MiniMaxProviderConfig): Promise<void> {
+    await super.initialize({
+      baseURL: 'https://api.minimax.io/v1',
+      defaultModelId: 'MiniMax-M3',
Evidence
Absent pricing yields undefined provider cost, while the budget estimator explicitly returns
undefined for non-OpenAI providers and the default budget policy refuses unpriced calls.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
MiniMax's inherited pricing and the budget estimator have no MiniMax rates, so dollar-budgeted calls are unpriced.
## Fix Focus Areas
- src/core/llm/providers/implementations/MiniMaxProvider.ts[6-14]
- src/api/runtime/spendBudget.ts[290-339]
## Recommended Fix
Provide MiniMax-specific pricing for provider usage and budget estimates, including both configured default models; test budget admission and recorded spending.

@octo-patch octo-patch changed the title feat: add MiniMax text provider feat(minimax): add M3.1 Flash text defaults and reasoning replay Oct 20, 2026
…eys per route, the GMI default and error mapping

A MiniMax key with OLLAMA_BASE_URL set, or with the claude CLI on PATH,
auto-detects Ollama or the CLI for text, though the documented order puts
API keys first; image detection keeps MiniMax after the other image
providers. The query router defaults to OpenAI with an empty key when the
MiniMax key is the only one set, and an explicit MiniMax route sends the
OpenAI key when one is also set. The GMI default under a MiniMax-only
configuration and the inherited error mapping (401, 429 with Retry-After,
a body that is not JSON) are pinned as they stand.
… each query router route its own provider's key

Text auto-detection checks MINIMAX_API_KEY right after REQUESTY_API_KEY,
before the CLI binaries and OLLAMA_BASE_URL, as the documented order puts
API keys first; image detection keeps MiniMax after the other image
providers, so the probe ahead is scoped to text. The getting-started,
high-level API and CLI provider pages list it there.

The query router defaults its classifier and generator to MiniMax and
MiniMax-M3.1-Flash when the MiniMax key is the only one set, after every
other key as the provider manager and auto-detection rank it. A route to a
provider other than OpenAI takes that provider's own key variable, or none,
and no URL from the router, so generateText resolves its credentials and
endpoint and another vendor's key or Ollama's URL never reaches it. An
OpenAI route keeps its fallback to the OpenRouter key and URL.

… MiniMax's embedding refusal

A MiniMax key alone must leave the router's embeddings on OpenAI, so an
embedding key a caller gives for the default text-embedding-3-small reaches
OpenAI instead of a MiniMax provider. An embedding provider other than
OpenAI takes its own key variable, so an OpenAI key never reaches Gemini or
MiniMax. MiniMax publishes no embedding model, so its provider refuses an
embedding request before any HTTP request is made.
… an embedding provider its own key

MiniMax publishes no embedding model, so a MiniMax key alone leaves the
router's default embedding provider on openai: an embedding key a caller
gives for the default text-embedding-3-small reaches OpenAI, and without
one the router finds no embedding key and stays on keyword retrieval.

An embedding provider other than OpenAI that has a key variable of its own
takes that key, or none, as the classifier and generator routes do, so an
OpenAI key is never sent to Gemini or MiniMax. An OpenAI embedding provider,
and one without a key variable such as Ollama, keeps the scan of the
provider keys.

The MiniMax provider refuses an embedding request before any HTTP request,
so no key travels to an endpoint MiniMax does not publish. The class
documentation names its endpoint, its default model and the refusal. The
query router pages describe each route's key and the embedding fallback,
and the high-level API page says the MiniMax provider refuses embeddings.

Two commits since your last review: a test commit and its fix. The fix keeps the query router's default embedding provider off MiniMax, gives an embedding provider other than OpenAI its own key variable, and has the MiniMax provider refuse embeddings before any HTTP request.

…er of another vendor

The router's apiKey configures the classifier and the generator. With
MINIMAX_API_KEY alone they default to MiniMax while embeddings default to
OpenAI, so a MiniMax key given as apiKey must not reach the OpenAI embedding
provider. When embeddings use the classifier's provider, they still take
that key.
…r the classifier's or the generator's provider

The router's apiKey and baseUrl configure the classifier and the
generator. Embeddings now take them only when they use one of those
providers, so with MINIMAX_API_KEY alone a MiniMax key given as apiKey no
longer reaches the OpenAI embedding provider that MiniMax-only routers
default to; embeddings stay on keyword retrieval with no key of their own.
The ordered scan of the provider key variables is one helper that the
generation and embedding paths share. The type docs and the query router
pages describe the rule.

…om the query router

With GEMINI_API_KEY and OPENROUTER_API_KEY set and no OpenAI key, a Gemini
embedding provider must get no base URL from the router, never OpenRouter's
compatibility URL, which belongs to an OpenAI embedding provider on the
OpenRouter key; a second case pins that one.
…L from the query router

The OpenRouter compatibility URL the router falls back to belongs to an
OpenAI embedding provider on the OpenRouter key. Any other embedding
provider, unless the router's own baseUrl applies to it as the
classifier's or the generator's provider, now gets no URL and uses its
own endpoint, as the classifier and generator routes do, so a Gemini key
is never paired with OpenRouter's URL. The type docs and both query
router pages say so.

@codex review

Your last review was of bfc30d5 on 16 October. Since then the query router gives each classifier, generator and embedding route its own provider's key and URL, the auto-detection ranks a MiniMax key with the other API keys for text, and MiniMaxProvider refuses embeddings. Please review the final head 59460be.

P2 Badge Classify MiniMax text models before resolving image defaults

When a host pins the newly documented text model via setDefaultProvider({ provider: 'minimax', model: 'MiniMax-M3.1-Flash', apiKey }) and later calls generateImage() without overrides, globalModelForTask() only recognizes families in CHAT_MODEL_FAMILY (which omits MiniMax), so it retains this text model instead of selecting the adjacent image-01 default; MiniMaxImageProvider then posts MiniMax-M3.1-Flash to /image_generation and the image call fails. Add MiniMax to chat-model detection and pin this global-default cross-task path.

P2 Badge Include MiniMax in the automatic planner rotations

When missions offer MiniMax alongside any existing listed provider (for example, ['minimax', 'openai']), every automatic strategy passes a preferred array that still omits minimax; pickProvider() filters against that array, so MiniMax is never in the rotation despite this new defaults entry. Fresh evidence at the final head is the unchanged best/cheapest/balanced preference arrays below this entry; include MiniMax in those arrays and cover a mixed-provider mission.

P2 Badge Replace inherited model-endpoint health probes

The class now explicitly suppresses model-API catalog access, but it still inherits OpenAIProvider.checkHealth() and its auth-key recheck probe, which issue GET /models/<default> and GET /models respectively. In deployments that call checkOverallHealth() this reports a functioning MiniMax chat endpoint unhealthy, and in multi-key pools an auth-failed key cannot be restored via the endpoint this integration says is unavailable; use a MiniMax-supported lightweight chat probe (and expose/override the pool probe) instead.

P2 Badge Use the MiniMax key-pool strategy when initializing

When MINIMAX_API_KEY contains multiple keys and the host sets AGENTOS_KEY_POOL_STRATEGY_MINIMAX=ordered, this delegation enters OpenAIProvider.initialize() without a strategy, so that method reads keyPoolStrategyFromEnv('openai'); the MiniMax-specific setting is ignored and traffic round-robins (or follows the OpenAI setting) instead. Resolve the default strategy with the minimax id before delegating, as the other OpenAI-compatible providers do.

Useful? React with 👍 / 👎.

…Max in the planner rotations, and its own key pool strategy

A global default that names MiniMax-M3.1-Flash must still make images with
image-01, never post the chat model to /image_generation. A mission that
offers MiniMax beside OpenAI must give MiniMax a node under the best,
cheapest and balanced strategies. A MiniMax key list must follow
AGENTOS_KEY_POOL_STRATEGY_MINIMAX, not the OpenAI variable.
