Gemini 3 Hype, GPT 5.1 Updates, & The Future of Custom GPTs

24 snips

Nov 18, 2025

Brian and Beth dive into the exciting advancements of Gemini 3 and GPT 5.1. With leaks suggesting Google might surpass OpenAI in model quality, the conversation heats up. They unpack the muddled waters of low-cost training claims, switching costs, and the impact of updates on custom GPTs. GPT 5.1 promises clearer outputs but is already breaking some setups. Plus, the rise of Sakana AI showcases Japan's own AI prowess. Expectations for Apple’s Siri to improve through Gemini integration hint at a competitive edge in the AI ecosystem.

Episode notes

ADVICE

Read The 5.1 Cookbook First

Read the 5.1 cookbook to learn practical changes and best practices for prompt design.
Use the cookbook to adapt custom GPTs before rolling updates to users.

ADVICE

Test Custom GPTs After Model Upgrades

Test every custom GPT after major model updates because behavior can change and triggers may break.
Be prepared to revise prompts, router docs, and trigger words quickly after upgrades.

ANECDOTE

Trigger Phrase Broke Client Demos

Brian built a trigger phrase "I'm ready to begin" for client GPTs which stopped working after an update.
The GPT skipped the prompt and invented outputs, forcing him to deliver a broken experience to clients.

Brian and Beth opened the week talking about post-travel exhaustion, holiday timing, and the usual Monday scramble before diving into the fast-moving AI news cycle. They framed the episode around two big topics: Gemini 3 and GPT 5.1, both expected to shape the competitive landscape going into the end of the year.

Key Points Discussed

Gemini 3 hype grows as leaks point to a major leap over 2.5 Pro.

Nate Jones claims Google may take the top spot for model quality for the first time.

Benchmark saturation makes performance harder to judge, so real workflow testing now matters more.

Concerns rise about switching costs as models continue to leapfrog each other.

Discussion on Kimi, DeepSeek, and recycled media hype around “low cost” training claims.

GPT 5.1 rollout improves instruction following and reduces jargon, but shifts may break existing custom GPT setups.

Issues with user preferences, model selection, and memory overriding developer-built instructions.

Prediction that custom GPTs and Gems may evolve into more structured, code-like agents built through vibe-coding style interfaces.

Exploration of how ecosystems (Google, Microsoft, OpenAI) may soon matter more than the standalone model.

Sakana AI becomes the most valuable private company in Japan.

Reflection on how quickly the AI industry has changed public visibility for figures like Jensen Huang.

Conversation on enterprise-grade update cycles and the future of agent maintenance.

Apple expected to benefit from Gemini integration as Siri gets significantly stronger with minimal user friction.
