MiniMax

MiniMax provider using the Anthropic-compatible API (recommended by MiniMax). Delegates to GoAI's Anthropic provider with MiniMax's endpoint.

Setup

go get github.com/zendev-sh/goai@latest

import "github.com/zendev-sh/goai/provider/minimax"

Set the MINIMAX_API_KEY environment variable, or pass WithAPIKey() directly.

Models

Model	Speed	Context	Notes
MiniMax-M2.7	~60 tps	204,800	Latest, self-evolving architecture
MiniMax-M2.7-highspeed	~100 tps	204,800	Fast variant (requires highspeed plan)
MiniMax-M2.5	~60 tps	204,800	Coding SOTA
MiniMax-M2.5-highspeed	~100 tps	204,800	Fast variant (requires highspeed plan)
MiniMax-M2.1	~60 tps	204,800	MoE 230B
MiniMax-M2.1-highspeed	~100 tps	204,800	Fast variant (requires highspeed plan)
MiniMax-M2	standard	204,800	First gen, agentic

Tested Models

E2E tested (real API calls, 2026-03-27): MiniMax-M2.7, MiniMax-M2.5, MiniMax-M2.1, MiniMax-M2

Generate, stream, thinking, and thinking stream verified on all 4 models. Tool calling verified on M2.7, M2.5, M2 (M2.1 requires system prompt for reliable tool output).

Usage

Basic

model := minimax.Chat("MiniMax-M2.7")

result, err := goai.GenerateText(ctx, model, goai.WithPrompt("Explain attention mechanisms"))
if err != nil {
    log.Fatal(err)
}
fmt.Println(result.Text)

Streaming

model := minimax.Chat("MiniMax-M2.7")

stream, err := goai.StreamText(ctx, model, goai.WithPrompt("Write a haiku"))
if err != nil {
    log.Fatal(err)
}
for chunk := range stream.TextStream() {
    fmt.Print(chunk)
}

Tool Calling

model := minimax.Chat("MiniMax-M2.7")

result, err := goai.GenerateText(ctx, model,
    goai.WithPrompt("What is the weather in Tokyo?"),
    goai.WithTools(weatherTool),
    goai.WithMaxSteps(3),
)

Thinking / Reasoning

MiniMax supports native Anthropic thinking blocks for step-by-step reasoning:

model := minimax.Chat("MiniMax-M2.7")

result, err := goai.GenerateText(ctx, model,
    goai.WithPrompt("Solve step by step: what is 23 * 47?"),
    goai.WithProviderOptions(map[string]any{
        "thinking": map[string]any{
            "type":         "enabled",
            "budgetTokens": 1000,
        },
    }),
)
// Reasoning content in result.ProviderMetadata["anthropic"]["reasoning"]

Options

Option	Type	Description
WithAPIKey(key)	string	Set a static API key
WithTokenSource(ts)	provider.TokenSource	Set a dynamic token source
WithBaseURL(url)	string	Override the default https://api.minimax.io/anthropic endpoint
WithHeaders(h)	map[string]string	Set additional HTTP headers
WithHTTPClient(c)	*http.Client	Set a custom *http.Client

Notes

• Uses MiniMax's Anthropic-compatible API (recommended by MiniMax over OpenAI-compatible).
• Text-only input/output. Image and document input not supported.
• Supports thinking/reasoning via Anthropic's native thinking blocks (ProviderOptions["thinking"]).
• Environment variable MINIMAX_BASE_URL can override the default endpoint (e.g., for China: https://api.minimaxi.com/anthropic).
• M2.1 tool calling requires a system prompt for reliable output.
• Highspeed model variants require a specific MiniMax token plan.
