In the ever-evolving landscape of artificial intelligence, 2023 marked a pivotal moment with the creation of MyGPT, the world's first ChatGPT-powered Alexa skill. This groundbreaking integration bridged the gap between OpenAI's sophisticated language model and Amazon's ubiquitous voice assistant, setting a new standard for conversational AI in smart home environments.
The Genesis of a Game-Changing Idea
Identifying the Opportunity
As ChatGPT took the world by storm in late 2022, AI enthusiasts and developers quickly recognized its potential to revolutionize various aspects of technology. However, a glaring gap remained in the realm of voice-controlled AI assistants. Despite Alexa's widespread adoption and ChatGPT's advanced language capabilities, no one had successfully merged these two powerful technologies—until MyGPT.
From Concept to Prototype
The journey of MyGPT began with a simple yet profound realization: combining ChatGPT's linguistic prowess with Alexa's voice interface could create an AI assistant of unprecedented capability. The initial prototype, remarkably, came to life in just one day:
- Developers repurposed an existing Wikipedia Skill written in Go.
- They replaced Wikimedia API calls with OpenAI API calls.
- This basic transformation yielded immediate, impressive results.
The prototype demonstrated the potential for a more intuitive, conversational AI experience, reminiscent of the futuristic computers depicted in science fiction.
Overcoming Technical Hurdles
While the concept proved promising, transforming the prototype into a robust, user-friendly Alexa skill presented several significant challenges.
Challenge: OpenAI's response times often exceeded Alexa's 8-second timeout limit.
Solution:
- Implemented a streaming approach using OpenAI's API.
- Utilized the
neurosnap/sentencesGo library for sentence segmentation. - Introduced a 7.5-second cutoff to ensure complete sentences.
- Added prompts for users to request additional information for incomplete responses.
2. Enhancing User Experience
Challenge: Long waits for responses disrupted the natural flow of conversation.
Solution:
- Leveraged Alexa's "Progressive Responses" feature.
- Delivered partial responses every second, including all complete sentences received.
- Fine-tuned volume settings for consistent audio across all response types.
3. Mitigating Network Issues
Challenge: Intermittent slow responses or connection problems with OpenAI's servers.
Solution:
- Set a 7-second timeout for HTTP connections using Go's
timeoutparameter. - Implemented retry logic with Hashicorp's
go-retryablehttplibrary. - Added a subtle jingle to bridge gaps in response times.
4. Ensuring Reliability
Challenge: Achieving a 100% success rate for Alexa responses.
Solution:
- Implemented a
selectstatement with a timer to wrap core functionality. - Utilized channels for managing asynchronous responses.
- Developed fallback responses for various error scenarios.
Code Innovation: Balancing Responsiveness and Reliability
The following code snippet illustrates the innovative approach to ensuring timely responses while maintaining reliability:
chatCompletionTimer := time.NewTimer(7500 * time.Millisecond)
fullSentencesSinceLastProgressiveResponseChan := make(chan string, 1)
entireSpeechChan := make(chan string, 1)
go func() {
// Asynchronous ChatGPT response handling
// Channel writing logic
}()
var fullSentencesSinceLastProgressiveResponse, entireSpeech string
select {
case <-chatCompletionTimer.C:
fullSentencesSinceLastProgressiveResponse = l.Get(r.TakingLongerToGetResponse)
entireSpeech = fullSentencesSinceLastProgressiveResponse
case fullSentencesSinceLastProgressiveResponse = <-fullSentencesSinceLastProgressiveResponseChan:
entireSpeech = <-entireSpeechChan
chatCompletionTimer.Stop()
}
This code ensures that the skill always responds within Alexa's required timeframe, gracefully handling potential delays from OpenAI's servers.
The Impact and Evolution of MyGPT

Lessons for AI Prompt Engineers
The development of MyGPT offers valuable insights for AI prompt engineers and developers:
Adaptability is crucial: Be prepared to modify your approach based on the limitations of the platforms you're working with. In the case of MyGPT, this meant finding creative solutions to work within Alexa's timeout constraints.
User experience should guide technical decisions: Features like progressive responses significantly improve interaction quality. Always consider how technical implementations will impact the end-user experience.
Robust error handling is non-negotiable: Anticipate and gracefully manage various failure scenarios. MyGPT's success hinged on its ability to provide reliable responses even when faced with network issues or delayed API responses.
Performance optimization is an ongoing process: Continuously monitor and refine response times and reliability. The development team behind MyGPT consistently iterated on their design to improve performance.
Context awareness is key: As AI assistants become more sophisticated, understanding and maintaining context throughout conversations becomes increasingly important. Future iterations of MyGPT and similar skills will likely focus on improving this aspect.
The Future of Voice-Controlled AI Assistants
As we look ahead to 2025 and beyond, the success of MyGPT has paved the way for even more innovative applications of AI in voice-controlled assistants. Several trends and developments are shaping the future of this technology:
1. Enhanced Language Models
The rapid advancement of language models since ChatGPT's initial release suggests that future AI assistants will have even more sophisticated language understanding and generation capabilities. Models like GPT-4 and its successors are likely to power increasingly natural and context-aware conversations.
2. Multimodal Interactions
Future AI assistants are expected to seamlessly integrate voice, text, and visual inputs. This could lead to more intuitive interactions where users can show objects to their AI assistant or reference visual information in their queries.
3. Personalization and Memory
AI assistants will become more personalized, remembering past interactions and user preferences to provide tailored responses and anticipate needs. This could include adapting language style, remembering important dates, or customizing recommendations based on individual user history.
4. Expanded Language Support
Building on MyGPT's initial support for English, German, and French, future AI assistants are likely to offer support for a wider range of languages and dialects, making the technology accessible to a global audience.
5. Integration with IoT and Smart Home Devices
Voice-controlled AI assistants will likely become central hubs for controlling and coordinating various smart home devices and Internet of Things (IoT) gadgets, offering more comprehensive home automation capabilities.
6. Enhanced Privacy and Security Measures
As AI assistants handle increasingly sensitive information, future developments will focus on strengthening privacy protections and giving users more control over their data.
