The Neuron: AI Explained

OpenAI dropped GPT-5.5, so we did the only reasonable thing: went live immediately and tried to break it.

In this off-the-cuff Neuron Live, Corey and Grant walk through OpenAI's GPT-5.5 release notes, benchmark claims, rollout details, and early access reactions before testing the model live across coding, reasoning, creativity, web research, and absurd prompt challenges. We also compare a few GPT-5.5 responses against Claude Opus 4.7, test Codex, build a new version of Cat Doom, and ask the important questions, like whether a sentient vending machine that only dispenses expired tuna salad deserves to live.

In this episode, we cover:

• What OpenAI says is new in GPT-5.5
• GPT-5.5’s improvements in coding, computer use, research, and knowledge work
• Early benchmark results across Terminal-Bench, GDPval, Frontier Math, BrowseComp, and scientific research tasks
• Why token efficiency may matter as much as raw intelligenceGPT-5.5’s rollout across ChatGPT, Codex, Plus, Pro, Business, and Enterprise
• Live Codex testing with a one-shot Cat Doom game buildCreative stress tests involving palindromes, time-traveling potatoes, dystopian vending machines, and Lord of the Rings product reviews
• First impressions of whether GPT-5.5 feels meaningfully different from GPT-5.4 and Claude Opus 4.7

This was not a formal benchmark. It was a first-contact livestream: messy, fast, weird, and exactly the kind of test we like.

Grant and Kyle dive into a comprehensive review and live test of the newly released Claude Opus 4.7, a cutting-edge large language model. This session explores its capabilities for coding and game dev, specifically referencing the "Renaissance / Plan Final Fantasy Tactics RPG Game" project. Discover how this ai model performs under pressure and its potential impact on game design workflows.

Anthropic just dropped Claude Opus 4.7, and we’re putting it through the gauntlet in real time.

Join Grant Harvey (Lead Writer at The Neuron) for an unscripted, warts-and-all test of Anthropic’s newest flagship model.

What we’re testing
- Advanced coding on tasks Opus 4.6 struggled with
- New higher-resolution vision support for images up to ~3.75 megapixels
- File system-based memory across multi-session work
- The new xhigh effort level, which sits between high and max
- Claude Code’s new /ultrareview slash command
- Auto mode for longer, less-interrupted agent runs

Why this matters
Opus 4.7 is the first model Anthropic is releasing with its new automatic cyber safeguards, following last week’s Project Glasswing announcement.

It’s also the direct upgrade path from Opus 4.6 at the same price:
- $5 per million input tokens
- $25 per million output tokens

If you build on Claude, this is likely the model you’ll be using next.

What’s changing under the hood
- New tokenizer, where the same input can map to more tokens depending on content type, roughly 1.0x to 1.35x
- State-of-the-art score on GDPval-AA, a third-party evaluation of economically valuable knowledge work
- Better instruction following, which means prompts written for earlier models may now behave differently
- Improvements across finance agent evals, document reasoning, and long-context tasks

Bring your hardest prompts. We’ll run them live and show you what breaks, what shines, and whether it’s worth migrating today.

AI can reason about text and images, but it still struggles to understand the physical world.

In this episode, Grant sits down with Peter Wilczynski, Chief Product Officer at Vantor (formerly Maxar Intelligence / Digital Globe), to unpack why spatial intelligence is emerging as critical AI infrastructure. Peter spent years at Palantir building ontology systems and mapping tools for defense operations before joining Vantor, where his team has built a 100M+ square kilometer 3D model of the entire Earth at 50cm resolution.

We dig into how satellite imagery becomes machine-readable through embedding models, why "ground truth world models" are fundamentally different from hallucinated ones, the Raptor GPS-alternative system, simulation and digital forensics, the future of augmented reality, and why the physical world might be the most important thing AI still doesn't understand.

Brandon Baum — better known as heybrandonb to his 25M+ followers — built a YouTube empire making cinematic, effects-heavy videos that look like they cost millions but were born in a bedroom during COVID. In this episode, we get into how he went from 2 views to a million followers in a month, why he shoots everything on iPhones with a custom 3D-printed dual-phone rig, how AI tools like Firefly Boards have replaced his Post-it Note wall, and why he thinks the atmosphere is "ripe for change" in Hollywood.

We also talk about what content is actually performing now (hint: it's not spectacle anymore), his plan to seed original IP on social before taking it to theaters, and why he's building custom AI agents to offload his admin so he can just be creative.

Let’s build with v0 in real time. We’re going LIVE with Tom Occhino, Chief Product Officer at Vercel, to explore vibe coding and take a hands-on look at v0, Vercel’s AI-powered development platform for building apps faster. We’ll show v0 live and walk through how it turns a simple prompt into a real, shippable interface. Tom will also explain what “vibe coding” actually looks like in practice, including how teams are using it today and where it fits into modern development workflows. What we’ll cover:⚡ You’ll see a live build using v0, from the first prompt to a working app.🧠 We’ll break down what vibe coding means and why so many teams are experimenting with it.🔐 Tom will share how Vercel thinks about AI-assisted development, including security, developer experience, and scale.🧭 We’ll talk about product, community, and where the Vercel ecosystem is headed next.❓ We’ll wrap with live Q&A and take questions from the chat. If you’re building products, shipping web apps, or thinking about how AI fits into your workflow, this session will give you a clear, practical look at what’s possible.Links: • Try v0: https://v0.app/• Vercel platform: https://vercel.com
