By ByteByteAI

Summary

## Key takeaways - **Reasoning models think before answering**: Early chatbots answered instantly token-by-token, but reasoning models now spend extra compute 'thinking' first, breaking complex problems into steps. Gemini 3 and similar models can adaptively dial reasoning effort based on task complexity—minimal for simple emails, high for math or debugging. [01:00:21], [01:58:21] - **RLVR replaces expensive human feedback**: Reasoning models shifted from RLHF (human ranking outputs) to RLVR, which uses verifiable checks like passing tests or correct math answers as reward signals. DeepSeek R1 proved this scales reasoning without massive labeling effort. [01:22:46], [01:34:47] - **Open-source coding model runs on PC**: Quen 3 Coder Next is an 80-billion parameter open-weight model released in early 2026 that narrows the gap with closed models and runs on a personal computer, exemplifying how open-source AI is catching up fast in coding capability. [04:20:33], [04:27:40] - **Open weights disrupt closed API dominance**: DeepSeek R1's open release in early 2025 was a turning point proving frontier capability can be open and reproducible, shifting the conversation from bigger models to accessibility through sparse architectures and compression advances. [05:00:18], [05:28:47] - **Agents still struggle with long workflows**: Today's agents handle short tasks well but lose context after many steps where small mistakes compound, and most run in cloud sandboxes cut off from real system access—persistent local agents aim to solve both limitations. [02:44:03], [03:14:31] - **World models simulate physics, not just pixels**: Video generation systems like DeepMind's Gen3 are learning how the physical world works, simulating physics and predicting outcomes. Training reliable world models will become a foundation for robots, autonomous vehicles, and physical AI systems. [06:55:14], [07:17:39]

AI models aren't just answering questions anymore. They are writing

questions anymore. They are writing entire code bases, controlling robots, and simulating physics. And the pace

isn't slowing down. 2026 started strong.

OpenAI introduced the GPT 5.3 codeex.

Antropic released Opus 4.6. Moonshot

open source Kim K2 with over a trillion parameters. and Alibaba shipped Quentry

parameters. and Alibaba shipped Quentry Coder next, narrowing the gap between open and closed coding models. Zooming

out, these releases highlight the broader direction AI is moving this year. Here are five key AI trends that

year. Here are five key AI trends that will likely shape 26.

One reasoning early chatbots like GPT4 answered the moment you hit enter. They

generated text token by token which worked well for writing but will fell short on questions that require multi-step thinking like math or coding problems. Reasoning models changed that

starting with open01 the model began spending extra compute thinking before replying so it could break a hard problem into smaller steps.

What made this practical was a shift in training. Earlier models used RLHF which

training. Earlier models used RLHF which relies on human ranking outputs and a learned reward model. That's expensive

and hard to scale. Reasoning models move to RLVR which uses verifiable checks like whether a test passes or a math answer is correct as the reward signal.

Deepsec R1 proved this approach scales reasoning without a massive labeling effort.

Today, most major labs have shipped reasoning models or baked reasoning into their flagships. But AI labs have moved

their flagships. But AI labs have moved from bigger models to efficiency. Models

like Gemini 3 can adaptively dial reasoning up or down depending on the task. For example, when the prompt is

task. For example, when the prompt is simple like summarize this email, it applies minimal reasoning but ramps it up for complex tasks like solving a math

problem or debugging code. Models like

Miniax M2.5 and Quinn 3.5 are also employing various sparse architectures to make these models more efficient and less expensive.

Two agents early models could answer questions, but they weren't trained to use tools. That's changed with agentic

use tools. That's changed with agentic models. Models trained on trajectories

models. Models trained on trajectories that include tool use. So they learn not just what they think but also request for tool use when needed. Today's agents

handle short tasks well but struggle with longer workflows. After many steps they lose context and the small mistakes compound. The other challenge is

compound. The other challenge is environmental access. Most agents run in

environmental access. Most agents run in sandboxes on the cloud, cut off from your email, files, and local apps by default, which limits how much they can

actually do in the real world.

In 26, expect persistent always on agents that manage work over hours or days. They will run locally so they have

days. They will run locally so they have access to your system such as email and terminal. Open Claw is an early example

terminal. Open Claw is an early example of this shift. With local and always on agents, reliability and security will likely become the next focus, resisting

prompt injection and not taking irreversible actions without approval.

Three, coding AI started helping developers with simple autocomplete, but the capability was limited. The model

could only see a few lines around your cursor. no understanding of the full

cursor. no understanding of the full codebase or project structure. Major AI

labs change that by training agentic coding LLMs on repositories and documentations.

After training these models run in an agentic loop where they can call coding specific tools like read file, search codebase, edit file and execute tests.

Antropics cloud code and opens codeex are leading this shift. Open source

models are also catching up fast. Quen 3

coder next is a powerful 80 billion parameter model released in early 26. It

is open weight small enough to run it on a personal computer.

The next wave is about three things.

Deeper repo understanding in large code bases, security aware workflows that bake in vulnerability checks before code

chips and faster end to end completions.

Four, open weights. For years, top performance LLMs were behind closed APIs. You could call a model but

APIs. You could call a model but couldn't run it locally or fine-tune it freely. Deep seek's open release of R1

freely. Deep seek's open release of R1 in early 25 was a turning point proving frontier capability can be open and

reproducible. Later more releases like

reproducible. Later more releases like OpenAI's GPTO OSS, Alibaba's Quen series and Miniax models made Open Weights more accessible.

In 26, the progress is less about bigger models and more about accessibility.

Expect a sparse mixture of expert architectures and advances in compression and inference that makes self-hosting more practical.

Five multimodel early models were text in text out. They

were not capable of processing input images or videos. That era is over.

Leading models are now natively multimodal.

You can upload a diagram and ask questions about it. The model can reason over text and images in a single conversation and produce a grounded

answer. Image and video generation is

answer. Image and video generation is hitting production quality too. Open

Sora 2 pushed video quality forward.

Google's VO 3.1 released late 25 and updated January 26 added controls like object insertion and richer audio. Image

generators like Nano Banana and Nanobanana 2 significantly improved text rendering and editing.

Two directions worth watching in 26 physical AI and world models. First,

physical AI like robots are moving from lab demos to real deployments.

We are seeing a wave of humanoid robots from Deep Minds Gemini robotics models to Tesla's Optimus.

Second, word models. Video generation

systems aren't just producing realistic pixels. They are learning how the

pixels. They are learning how the physical world works, simulating physics, and predicting outcomes. Deep

Minds Gen3 is a good example, already generating interactive 3D environments.

Training better world models will likely continue through 206.

If models can simulate environments reliably, they become a foundation for training robots, autonomous vehicles, and other systems that must operate in

the physical world. AI is moving faster than ever. What looks routine today

than ever. What looks routine today would have seemed like magic just a few years ago.

26 is shaping up to be a fascinating year to watch, and there's never been a better time to start building.
