-# GLM SDK Usage Guide
-
-## Matching the Provided Curl Request
-
-The SDK can replicate the exact curl request provided:
-
-```go
-package main
-
-import (
-    "context"
-    "fmt"
-    "log"
-    "tm/pkg/glm"
-    "tm/pkg/logger"
-)
-
-func main() {
-    config := &glm.Config{
-        BaseURL: "https://api.z.ai",
-        APIKey:  "4e267ac7897f4a789cacb3dbee15f312.coJtK3397qFv16x5",
-    }
-
-    logger := logger.NewLogger()
-    sdk, err := glm.New(config, logger)
-    if err != nil {
-        log.Fatal(err)
-    }
-
-    req := &glm.ChatCompletionRequest{
-        Model: "glm-4.5",
-        Messages: []glm.Message{
-            {
-                Role:    glm.MessageRoleSystem,
-                Content: "You are a high-precision translator specializing in professional tender documents. Always respond with only the translated English text — no explanations, notes, or markdown formatting.",
-            },
-            {
-                Role:    glm.MessageRoleUser,
-                Content: "Translate the following text from Swedish to English accurately and professionally:\n\"IT-stöd för projekt- och portföljstyrning\"",
-            },
-        },
-        Thinking: &glm.Thinking{
-            Type: "false",

-        TopP:             1,
-        FrequencyPenalty: 0,
-        PresencePenalty:  0,
-    }
-
-    ctx := context.Background()
-    resp, err := sdk.ChatCompletion(ctx, req)
-    if err != nil {
-        log.Fatal(err)
-    }
-
-    if len(resp.Choices) > 0 {
-        fmt.Println(resp.Choices[0].Message.Content)
-    }
-}
-```
-
-## Using the Translate Convenience Method
-
-For the specific translation use case:
-
-```go
-translated, err := sdk.Translate(ctx, "IT-stöd för projekt- och portföljstyrning", "Swedish", "English")
-if err != nil {
-    log.Fatal(err)
-}
-fmt.Println(translated) // Output: "IT support for project and portfolio management"
-```
-
-### Custom Translation Options
-
-For more control over translation parameters:
-
-```go
-opts := &glm.TranslateOptions{
-    Model:            "glm-4.5",
-    MaxTokens:        1024,
-    Temperature:      0.1,  // Very low for consistent translations
-    FrequencyPenalty: 0.2,
-    PresencePenalty:  0.2,
-    EnableThinking:   &[]bool{false}[0],
-}
-
-translated, err := sdk.TranslateWithOptions(ctx, "IT-stöd för projekt- och portföljstyrning", "Swedish", "English", opts)
-if err != nil {
-    log.Fatal(err)
-}
-fmt.Println(translated)
-```
-
-## Advanced Configuration
-
-### GLM SDK Configuration
-
-```go
-config := &glm.Config{
-    BaseURL:                "https://api.z.ai",
-    APIKey:                 "your-api-key",
-    Timeout:                300 * time.Second,
-    RetryAttempts:          3,
-    RetryDelay:             2 * time.Second,
-    EnableLogging:          true,
-    DefaultModel:           "glm-4.5",
-    DefaultMaxTokens:       4096,
-    DefaultTopP:            1.0,
-    DefaultTemperature:     0.7,
-    DefaultFrequencyPenalty: 0.0,
-    DefaultPresencePenalty:  0.0,
-    EnableStreaming:        false,
-    EnableThinking:         false,
-
-    // Translation-specific configuration
-    TranslationMaxTokens:        2048,
-    TranslationTemperature:      0.3,
-    TranslationFrequencyPenalty: 0.1,
-    TranslationPresencePenalty:  0.1,
-    TranslationEnableThinking:   false,
-}
-```
-
-### Bootstrap Configuration (Application Level)
-
-Configure translation parameters via environment variables in your application bootstrap:
-
-```go
-// cmd/worker/bootstrap/config.go
-type GLMConfig struct {
-    // ... basic GLM settings ...
-
-    // Translation options configured via environment variables
-    TranslateOptions TranslateOptions
-}
-
-type TranslateOptions struct {
-    MaxTokens        int     `env:"GLM_TRANSLATE_MAX_TOKENS" default:"2048"`
-    Temperature      float64 `env:"GLM_TRANSLATE_TEMPERATURE" default:"0.3"`
-    FrequencyPenalty float64 `env:"GLM_TRANSLATE_FREQUENCY_PENALTY" default:"0.1"`
-    PresencePenalty  float64 `env:"GLM_TRANSLATE_PRESENCE_PENALTY" default:"0.1"`
-    EnableThinking   bool    `env:"GLM_TRANSLATE_ENABLE_THINKING" default:"false"`
-}
-```
-
-Set these environment variables to customize translation behavior:
-
-```bash
-export GLM_TRANSLATE_MAX_TOKENS=1024
-export GLM_TRANSLATE_TEMPERATURE=0.2
-export GLM_TRANSLATE_FREQUENCY_PENALTY=0.2
-export GLM_TRANSLATE_PRESENCE_PENALTY=0.2
-export GLM_TRANSLATE_ENABLE_THINKING=false
-```
-
-## Error Handling Examples
-
-```go
-resp, err := sdk.ChatCompletion(ctx, req)
-if err != nil {
-    var glmErr *glm.Error
-    if errors.As(err, &glmErr) {
-        switch glmErr.Code {
-        case glm.ErrCodeAuthentication:
-            log.Printf("Authentication failed: %s", glmErr.Message)
-            // Handle authentication error (e.g., refresh token)
-        case glm.ErrCodeRateLimit:
-            log.Printf("Rate limit exceeded: %s", glmErr.Message)
-            // Implement backoff strategy
-        case glm.ErrCodeInvalidRequest:
-            log.Printf("Invalid request: %s", glmErr.Message)
-            // Fix request parameters
-        case glm.ErrCodeServerError:
-            log.Printf("Server error: %s", glmErr.Message)
-            // Retry or alert administrators
-        default:
-            log.Printf("Unknown error: %s", glmErr.Error())
-        }
-    } else {
-        log.Printf("Non-GLM error: %v", err)
-    }
-    return
-}
-```
-
-## Streaming with Progress Tracking
-
-```go
-var fullResponse strings.Builder
-
-err := sdk.StreamChatCompletion(ctx, req, func(chunk *glm.StreamChatCompletionResponse) error {
-    if len(chunk.Choices) > 0 {
-        content := chunk.Choices[0].Delta.Content
-        fmt.Print(content) // Print as it comes
-        fullResponse.WriteString(content)
-    }
-
-    // Check for completion
-    if len(chunk.Choices) > 0 && chunk.Choices[0].FinishReason != nil {
-        fmt.Printf("\n\nFinished with reason: %s\n", *chunk.Choices[0].FinishReason)
-    }
-
-    return nil
-})
-
-if err != nil {
-    log.Fatal(err)
-}
-
-fmt.Printf("Complete response: %s\n", fullResponse.String())
-```
-
-## Integration with Tender Management System
-
-```go
-// In your service layer
-type TranslationService struct {
-    glmSDK *glm.SDK
-    logger logger.Logger
-}
-
-func NewTranslationService(glmSDK *glm.SDK, logger logger.Logger) *TranslationService {

-    })
-
-    return translated, nil

-## Health Monitoring
-
-```go

-
-## Model Management
-
-```go
-// List available models
-models, err := sdk.ListModels(ctx)
-if err != nil {
-    log.Fatal(err)
-}
-
-fmt.Println("Available models:")
-for _, model := range models.Data {
