GPT-5 Arrives, and We Try the New Alexa+

What It Covers

OpenAI releases GPT-5 with over 70 models powering enhanced capabilities, while Amazon launches Alexa Plus using generative AI. Both products demonstrate the challenges of integrating LLMs into existing consumer products with mixed results.

Key Questions Answered

• •GPT-5 Architecture: OpenAI deploys a router system that automatically selects the appropriate model based on query complexity, eliminating manual model selection for users. Free users now access reasoning capabilities previously reserved for paid subscribers, potentially transforming student usage patterns significantly.
• •Alexa Plus Technical Challenge: Amazon integrates over 70 specialized models to connect natural language processing with millions of deterministic APIs. The primary engineering challenge involves translating conversational requests into predictable computer commands while maintaining reliability for basic functions like timers and alarms.
• •Pricing Strategy: GPT-5 API costs $1.25 per million input tokens, matching Google Gemini but undercutting Anthropic's Claude Opus at $15 per million tokens. This aggressive pricing mirrors venture-subsidized ride-sharing tactics, suggesting major labs are prioritizing market share over immediate profitability.
• •Business Model Shift: Amazon positions Alexa Plus as a Prime membership benefit rather than ad-supported product, aiming to increase Prime stickiness through integrated benefits. Over 90% of early access users remain on the new system despite technical issues, indicating strong retention despite implementation challenges.
• •Reliability Regression: Both GPT-5 and Alexa Plus demonstrate the "two steps forward, one step back" pattern where new AI capabilities come at the cost of previously reliable basic functions. Hallucination rates decreased to approximately 1% for certain query types, but orchestration between LLMs and legacy systems remains problematic.
