+- If a namespace-style value is needed, import the module's own exported namespace by name, for example `import { Project } from "@opencode/core/project"`, then reference `Project.ID`.
 - Prefer dynamic imports for heavy modules that are only needed in selected code paths, especially in startup-sensitive entrypoints. Destructure dynamic import bindings near the top of the narrowest scope that needs them so they read like normal imports. Avoid inline chains such as `await import("./module").then((mod) => mod.value())` or `(await import("./module")).value()`. Keep branch-specific imports inside the branch that needs them to preserve lazy loading.

+
+Both read `ZAI_API_KEY` when `apiKey` is omitted and support an explicit `auth` override.
+Coding Plan requires an active subscription. `baseURL` overrides the selected API's
+complete base, including its version prefix. Language-model routes use HTTP/SSE.
+
+Options retain the selected API's native semantics:
+
+- Chat `reasoningEffort` lowers to `reasoning_effort`; Responses lowers it to `reasoning.effort`.
+  Messages `effort` lowers to `output_config.effort`. Omission preserves provider defaults.
+- Chat `thinking` passes `type` and `clear_thinking` through unchanged. Set
+  `clear_thinking: false` and replay complete `response.message` values to preserve reasoning
+  across user messages and tool loops. The standard API defaults to clearing historical thinking;
+  Coding Plan documents preservation by default.
+- Messages accepts `thinking: { type: "enabled" | "adaptive" | "disabled" }` without requiring
+  an Anthropic token budget. Coding Plan documents a disabled toggle as low-effort thinking
+  for GLM-5.3, with explicit effort taking precedence.
+- Chat also offers `toolStream`, `doSample`, `responseFormat`, `requestID`, and `userID`.
+  Tool-argument streaming is enabled when tools are present on GLM-4.6/4.7/5.x;
+  `toolStream: false` explicitly disables it. Older model families omit the opt-in.
+- Effort and thinking values remain forward-compatible strings. Their meaning is model-specific:
+  GLM-5.3 accepts `low`, `high`, and `max` effort and rejects disabled thinking with HTTP 400;
+  the direct GLM-5.2 recordings returned reasoning even with `none` and `minimal` effort,
+  whereas explicit `thinking.type: "disabled"` disabled it on GLM-5.2 and GLM-4.7.
+
+Standard API recordings cover GLM-5.3 efforts and a full preserved-reasoning tool loop with
+a subsequent user follow-up, GLM-5.2 efforts, older-model thinking toggles, GLM-4.5 tool calls,
+GLM-5.3-Flash image input, and JSON output. Coding Plan has unit coverage for routing,
+request options, and reasoning replay; successful live recordings are pending.
+
+Package entrypoints are `@opencode/ai/providers/zai`, `zai/chat`, `zai-coding-plan`,
+`zai-coding-plan/chat`, `zai-coding-plan/messages`, and `zai-coding-plan/responses`.
+
+## Moonshot
+
+Moonshot defaults to Chat Completions, with Messages and Responses selectors for Kimi K3:
+
+```ts
+import { LLM } from "@opencode/ai"
+import { Moonshot } from "@opencode/ai/providers"
+
+const moonshot = Moonshot.configure({ apiKey: process.env.MOONSHOT_API_KEY })
+
+const request = LLM.request({
+  model: moonshot.model("kimi-k3"), // also moonshot.chat("kimi-k3")
+  prompt: "Explain the tradeoffs in this design.",
+  providerOptions: { reasoningEffort: "high" },
+})
+
+const messages = LLM.request({
+  model: moonshot.messages("kimi-k3"),
+  prompt: "Explain the tradeoffs in this design.",
+  providerOptions: { effort: "high" },
+})
+
+const responses = LLM.request({
+  model: moonshot.responses("kimi-k3"),
+  prompt: "Explain the tradeoffs in this design.",
+  providerOptions: { reasoningEffort: "high" },
+})
+```
+
+When `apiKey` is omitted, authentication reads `MOONSHOT_API_KEY`, then `MOONSHOTAI_API_KEY`.
+Chat and Responses use `https://api.moonshot.ai/v1`; Messages uses
+`https://api.moonshot.ai/anthropic/v1`. `baseURL` overrides the selected API's complete base,
+including the version prefix, for regional endpoints or gateways. Each endpoint requires its own valid credentials.
+All three routes use HTTP/SSE.
+
+Reasoning options stay native to the selected API and model:
+
+| Model/API                   | Provider options                                                                        |
+| --------------------------- | --------------------------------------------------------------------------------------- |
+| K3 Chat / Responses         | `reasoningEffort: "low" \| "high" \| "max"`; default is `max`                           |
+| K3 Messages                 | `effort: "low" \| "high" \| "max"`; default is `max`                                    |
+| K2.6 Chat                   | `thinking: { type: "enabled" \| "disabled", keep?: "all" \| null }`; default is enabled |
+| K2.7 Code / high-speed Chat | Omit `thinking` to use always-on, preserved reasoning                                   |
+
+Omitting options preserves the model's defaults. K3 uses effort rather than the K2.x `thinking`
+parameter. Known effort values have autocomplete while future strings remain accepted.
+For K2.6, `thinking.keep: "all"` enables preservation of reasoning across user messages.
+K3 and both K2.7 Code variants always preserve reasoning. Continue with the returned
+`response.message` and matching tool results so reasoning content and any Messages signatures are retained.
+Leave sampling options such as `temperature` unset to use these models' fixed defaults.
+
+The recorded suite covers all three K3 APIs, default and explicit efforts, K2.6 thinking modes,
+both K2.7 Code variants, generated tool loops with a subsequent user follow-up, required/disabled
+tool choice, image-byte input, and native structured output through `http.body` overlays.
+K3 Chat and Messages accept required and disabled tool choice. Responses supports automatic tool
+choice only; explicit `required` and `none` produce a provider `InvalidRequest` error, also covered by recordings.
+The provider targets the Moonshot Open Platform; Kimi Code is a separate product and endpoint.
+
+Package entrypoints are `@opencode/ai/providers/moonshot`, `moonshot/chat`, `moonshot/messages`,
+and `moonshot/responses`; each exports `model(modelID, settings)`.
+
+## MiniMax
+
+MiniMax defaults to its Messages API and reads `MINIMAX_API_KEY` when `apiKey` is omitted:
+
+```ts
+import { Effect, Layer } from "effect"
+import { LLM, LLMClient } from "@opencode/ai"
+import { MiniMax } from "@opencode/ai/providers"
+import { RequestExecutor } from "@opencode/ai/route"
+
+const minimax = MiniMax.configure({ apiKey: process.env.MINIMAX_API_KEY })
+const request = LLM.request({
+  model: minimax.model("MiniMax-M3"), // also minimax.messages("MiniMax-M3")
+  prompt: "What is 173 multiplied by 219?",
+  providerOptions: { thinking: { type: "adaptive" } },
+  generation: { maxTokens: 1536 },
+})
+
+const layer = LLMClient.layer.pipe(Layer.provide(RequestExecutor.fetchLayer))
+const response = await Effect.runPromise(LLMClient.generate(request).pipe(Effect.provide(layer)))
+console.log(response.text)
+```
+
+Select `minimax.chat("MiniMax-M3")` or `minimax.responses("MiniMax-M3")` for MiniMax's native Chat Completions
+and Responses APIs. The matching package entrypoints are `@opencode/ai/providers/minimax/messages`,
+`@opencode/ai/providers/minimax/chat`, and `@opencode/ai/providers/minimax/responses`.
+
+- **Messages:** M3 thinking defaults off. Set `thinking: { type: "adaptive" }` to enable it or
+  `thinking: { type: "disabled" }` to disable it.
+- **Chat:** M3 thinking defaults on and uses the same `thinking` control. The provider enables `reasoning_split`
+  by default so reasoning is separate from answer text; `reasoningSplit: false` selects native `<think>`-tagged text.
+- **Responses:** M3 reasoning defaults off. `reasoningEffort: "none"` disables it; `"minimal"`, `"low"`,
+  `"medium"`, and `"high"` enable reasoning without changing its depth.
+
+M2.x models always think, even when a disabling option is supplied. For tool continuations, retain the complete
+`response.message` in history before adding `Message.tool(...)` results; this preserves reasoning and any signatures.
+
+The default API bases are `https://api.minimax.io/anthropic/v1` for Messages and `https://api.minimax.io/v1` for
+Chat and Responses. `configure({ baseURL })` replaces the selected API's base, including its version prefix.
+
+## Meta
+
+Use Meta's direct [Model API](https://dev.meta.ai/docs/overview) with `META_API_KEY`:
+
+```ts
+import { Meta } from "@opencode/ai/providers"
+
+const meta = Meta.configure() // or Meta.configure({ apiKey })
+const request = LLM.request({
+  model: meta.responses("muse-spark-1.3"), // meta.model(...) also selects Responses
+  prompt: "What is 173 multiplied by 219? Reply with the integer.",
+  providerOptions: { reasoningEffort: "low" },
+  generation: { maxTokens: 1024 },
+})
+```
+
+`meta.chat("muse-spark-1.3")` selects Chat Completions; `meta.messages("muse-spark-1.3")` selects
+the Anthropic-compatible Messages API. All use `https://api.meta.ai/v1`. The package entrypoints
+`@opencode/ai/providers/meta/responses`, `meta/chat`, and `meta/messages` expose `model(modelID, settings)`.
+
+[Muse Spark](https://dev.meta.ai/docs/models) supports `minimal`, `low`, `medium`, `high`, and
+`xhigh` reasoning effort; standard-tier 1.3 also supports `max`. Omitting effort uses the model's
+default. Muse Spark always reasons and rejects `none`. The output-token budget includes private reasoning.
+
+Responses defaults to `store: false` and `include: ["reasoning.encrypted_content"]`. Preserve
+`response.message` along with matching `Message.tool(...)` results in subsequent requests to replay
+reasoning through tool loops. Optional `reasoningSummary: "auto"` requests a readable summary.
+For server-managed history, override `store: true, include: []` and send the response ID through
+`http: { body: { previous_response_id: responseID } }` with only the new input.
+Chat Completions redacts private reasoning and cannot carry it between calls.
+Responses and Chat support only `toolChoice: "auto"` (the default). Messages also accepts `"none"`;
+its documented forced `"any"` choice currently returns HTTP 400. Messages defaults to adaptive thinking
+with `display: "omitted"`, preserving encrypted `redacted_thinking` in `response.message`. Use
+`providerOptions: { effort: "low" }` for depth or `thinking: { type: "enabled", budgetTokens: 1024 }`
+for budget compatibility (with `generation.maxTokens > 1024`).
+
+Add `tools: [Meta.webSearch()]` to a Spark Responses or Messages request for hosted web search.
+Responses exposes hosted results and URL citations in text-part `providerMetadata.meta.annotations`.
+To include search result lists, set `include: ["reasoning.encrypted_content", "web_search_call.results"]`.
+Messages exposes hosted search calls; the recorded Messages API stream does not supply structured
+citations or separate result blocks. Retain `response.message` for either API's continuation.
+
+Use `Image.generate` for one-off generation or editing:
+
+```ts
+import { Image, ImageInput } from "@opencode/ai"
+
+const generation = Image.generate({
+  model: meta.image("muse-image-1.0"),
+  prompt: "A flat black square on a white background.",
+  options: { n: 1, reasoningStrength: "low" },
+})
+
+const edit = Image.generate({
+  model: meta.image("muse-image-1.0"),
+  prompt: "Make the square purple.",
+  images: [ImageInput.bytes(imageBytes, "image/webp")],
+  options: { outputFormat: "png", reasoningStrength: "low" },
+})
+```
+
+The default image format is WEBP; `outputFormat` also accepts PNG/JPEG and `responseFormat: "url"`
+returns a signed URL. `size` is an aspect-ratio hint. For conversational images, select
+`meta.responses("muse-image-1.0")` with `tools: [Meta.imageGeneration({ reasoningStrength: "low" })]`.
+Generated images are provider-executed tool results with file content. Retain `response.message` to
+replay the signed image handle on the next request. Muse Image accepts only the `image_generation` tool.
+
+Meta Responses is explicitly HTTP/SSE-only and does not use WebSockets, even when a caller supplies
+`StreamOptions.webSocket`. The public `/v1/responses` endpoint rejects WebSocket upgrades with HTTP 405 (`Allow: POST`).
+

 OpenAI Responses has one semantic route and uses HTTP by default. Advanced callers may supply a per-call WebSocket channel executor through `StreamOptions`; transport policy does not change provider settings, model identity, or route identity. The provider-neutral Open Responses implementation owns the reusable WebSocket request and event contract, while each provider opts in with its own handshake and connection policy. Azure follows the same Chat/Responses split at `providers/azure/chat` and `providers/azure/responses`. Generic OpenAI-compatible Chat remains at `providers/openai-compatible`; the Responses adapter at `providers/openai-compatible/responses` uses the provider-neutral Open Responses protocol. OpenAI Responses extends that baseline with OpenAI tools, event variants, metadata, and defaults. Generic Anthropic Messages-compatible providers use `providers/anthropic-compatible`, which the named Anthropic provider composes.
