The latest versions of Anthropic’s Claude generative AI models made their debut Thursday, including a heavier-duty model built specifically for coding and complex tasks.

Anthropic launched the new Claude 4 Opus and Claude 4 Sonnet models during its Code with Claude developer conference, and executives said the new tools mark a significant step forward in terms of reasoning and deep thinking skills.

The company launched the prior model, Claude 3.7 Sonnet, in February. Since then, competing AI developers have also upped their game. OpenAI released GPT-4.1 in April, with an emphasis on an expanded context window, along with the new o3 reasoning model family. Google followed in early May with an updated version of Gemini 2.5 Pro that it said is better at coding.

Claude 4 Opus is a larger, more resource-intensive model built to handle particularly difficult challenges. Anthropic CEO Dario Amodei said test users have seen it quickly handle tasks that might have taken a person several hours to complete. 

«In many ways, as we’re often finding with large models, the benchmarks don’t fully do justice to it,» he said during the keynote event.

Claude 4 Sonnet is a leaner model, with improvements built on Anthropic’s Claude 3.7 Sonnet model. The 3.7 model often had problems with overeagerness and sometimes did more than the person asked it to do, Amodei said. While it’s a less resource-intensive model, it still performs well, he said. 

«It actually does just as well as Opus on some of the coding benchmarks, but I think it’s leaner and more narrowly focused,» Amodei said.

Anthropic said the models have a new capability, still being beta tested, in which they can use tools like web searches while engaged in extended reasoning. The models can alternate between reasoning and using tools to get better responses to complex queries.

The models both offer near-instant response modes and extended thinking modes. 

All of the paid plans offer both Opus and Sonnet models, while the free plan just has the Sonnet model.

Marvel Rivals has been a breath of fresh air for the hero shooter genre, combining popular comic book characters and chaotic third-person shooter action to create epic team fights that keep me coming back for more.

Fast-paced combat is the name of the game in Marvel Rivals, which is why it could come across as a confusing development that the next limited-time mode launching in Marvel Rivals Season 2.5 is a form of auto battler (also frequently referred to as auto chess).

Ultron’s Battle Matrix Protocol is an experimental mode launching on June 6, where six players will draft teams of heroes to go head to head with their opponents’ drafts. You’ll be able to support your AI teams while the new hero Ultron (also debuting in season 2.5) is chipping in extra healing and damage to the fight.

Aside from the fact that it’ll be cool to stage your own version of Marvel Comics’ Secret Wars, is the decision to add an auto battler to Marvel Rivals (which has previously released limited-time modes that mostly tracked with the shooter’s core gameplay loop) really all that far out of left field? I don’t think so.

Why is Marvel Rivals getting an auto battler mode?

The new mode is similar to multiplayer online battle arena spinoffs such as Dota Auto Chess and League of Legends’ Teamfight Tactics. I think drawing the line from a multiplayer online battle arena (MOBA) to auto battler is easy for most people.

MOBAs are strategy games first and foremost, where players pick and choose items to craft builds that will help them win their lane, while also contributing to big team fights. Players need to work together to overwhelm the other team and push them back to their spawn.

MOBAs and auto battlers are both about team synergy, positioning and picking the right upgrades, so it’s not surprising to people when characters from a game in one of these genres appear in another.

There are many people that wouldn’t associate hero shooters with MOBAs in the slightest. Games like Marvel Rivals have a high ceiling for very different mechanical skills — especially aiming. But hero shooters are also complex strategy games that share many of the same fundamentals as a MOBA.

Putting together a viable team composition with strong character is the most important part of a hero shooter — and Marvel Rivals takes this to another level with the strongest team-up abilities that require multiple heroes to activate.

An auto battler will allow people to experiment team compositions that don’t often get played in real Marvel Rivals’ matches, and could even help the community find new experimental hero combinations that have the potential to shake up common ways people play the game.

In Ultron’s Battle Matrix Protocol, as the auto battler mode is called, players will be able to put together balanced teams, lock in the risky GATOR strategy (which is nightmarishly similar to Overwatch’s GOATS meta) or fall back on triple support with brand new upgrades that change how the game works.

Absurd power scaling might look like Overwatch 2’s Stadium mode

There’s a clear rivalry between Overwatch 2 and Marvel Rivals, since they’re the two biggest hero shooters on the market right now. Blizzard’s hero shooter is entering its ninth year of life with flagging interest, but its solid fundamentals have been a high bar for Marvel Rivals to hurdle.

Both games have been trying out bold new things — Overwatch 2 recently shipped the MOBA-like Stadium mode that lets players augment popular abilities and take powerful passives as they fight in a flurry of different objectives in a best of seven gauntlet.

Ultron’s Battle Matrix Protocol in some ways feels like NetEase’s response to Blizzard’s big success with Stadium mode. You might not have quite as much influence on the outcome of each battle, but this serves as a proof of concept for Marvel Rivals’ hero power scaling.

This new mode also lets players pick passive abilities that buff certain roles as well as more powerful hero-specific upgrades that drastically alter the course of a fight, so the snowballing power of a Stadium match is very much emulated here.

In the Season 2.5 developer vision video, we got a look at what some of the upgrades will look like.

Venom can grow into a hulking monster after devouring enemies with his ultimate ability, Hela cuts a swath through the playing field with a field of flying daggers, Psylocke zips around her ultimate ability’s area of effect at twice her normal speed and Namor summons many more squid turrets to attack his enemies.

It’s safe to assume that every character in the game will have some kind of special power unlocked in the later rounds of an Ultron’s Battle Matrix Protocol match. This definitely isn’t NetEase reheating Blizzard’s nachos, but I do think it’s indicative of a broader shift toward making hero shooters feel a little bit more chaotic and unrestrained.

Game balance is important, but one of the biggest draws of this genre is that each character is a unique power fantasy you can’t find elsewhere. I can’t imagine such in-depth upgrades were designed for a one-and-done mode, so it’ll be interesting to see where they might show up next.
