Every Character AI Model Ranked from Best to Worst

Quick Answer: LongSqueak is the strongest Character AI chat style on current reports, and unlimited use of it needs c.ai+, which also adds DeepSqueak and Soft Launch. Since 28 September 2026, new chats start on PipSqueak 3, which is free and too new to rank, ShortSqueak is a second free style built for short replies, and PipSqueak 2 and PipSqueak 2 Rawr sit in the Legacy menu. Roar, Pawly, Goro and Dynamic were retired on 28 April 2026 and Meow and Nyan on 8 May, so any ranking that still crowns Roar is describing a lineup that does not exist.

Character AI calls them “chat styles,” and the list is shorter than it used to be. The clearout ran from 28 April to 8 May 2026, PipSqueak 2 Rawr began rolling out to every account on 29 May, and on 28 September Character AI added two free styles, PipSqueak 3 and ShortSqueak.

That matters more than the old ranking arguments did, because new chats now open on PipSqueak 3 and c.ai+ still adds three more styles.

This guide covers the seven styles in service, what each does in practice, what people are complaining about right now, and what happened to the six that were removed.

What Character AI Models Are and How They Work

Character AI models are named AI configurations, meaning distinct versions of the platform’s underlying language model, each tuned for a specific writing style, response length, and character consistency. They are not fully separate AI systems.

Internally, Character AI calls them “chat styles.” Character AI confirmed on their official blog that they build these models by fine-tuning open-source architectures through a proprietary training pipeline.

Community network analysis further revealed that the newer models (PipSqueak and DeepSqueak) run on a model family called DEEP_SYNTH, with PipSqueak using DEEP_SYNTH_LITE and DeepSqueak using the full version.

The retired styles ran on separate configurations with different defaults for tone and length, which is why their removal felt so much bigger than a settings change.

What matters in practice is that each style produces noticeably different output from the same character. The same scene reads sharp and tense on Rawr and slower and more descriptive on the PipSqueak 2 base.

Switching styles is still the most underused lever on the platform, and it costs a free user nothing, because PipSqueak 3 and ShortSqueak are both free.

The current roster is: PipSqueak 3 and ShortSqueak free on any account, PipSqueak 2 and PipSqueak 2 Rawr in the Legacy menu, and DeepSqueak, Soft Launch and LongSqueak on c.ai+. Free accounts receive the two new styles over the days after 28 September, and Character AI’s moderators say an out-of-date app can hide them, so update the app if they are missing. Our PipSqueak 3 guide covers the new default and how to go back to PipSqueak 2.

If you have already cycled through every style and still want a companion that holds a long scene, Candy AI is where we point Character AI users first.

Every Character AI Model Ranked

LongSqueak is the strongest of the three c.ai+ styles on current reports. DeepSqueak sits alongside it on the paid tier and is the less dependable of the two right now. On a free account, new chats open on PipSqueak 3, ShortSqueak covers quick chats, and PipSqueak 2 and Rawr now sit in the Legacy menu.

No head-to-head scoring exists for this generation, so the table reports what each style was built to do and what it is being criticized for, with no scores, and the sources sit in the notes under the table:

LongSqueak is the only one of the three paid styles with a published specification. Character AI announced it in early August 2026 as a style “made for long-form roleplay and storytelling with 4x the memory”, saying replies “read more like a novel” and that it “draws more deeply on Lorebook and Memory as it writes”.

It shipped with Style Control, a set of dials in the style picker. Response length runs Long, Looong or Loooooong, and a second dial tilts replies toward dialogue or narration. There is no short setting, which catches out most people who turn it on.

Reception has been unusually warm for a Character AI release. In a 7 September thread about still enjoying the app, one commenter called LongSqueak “the best update they’ve put out in a long while” and singled out the memory. Our LongSqueak explainer covers the rollout, including why some paying accounts still cannot see it.

DeepSqueak needs checking before you commit a long scene to it. Through the first week of September 2026, paying users posted transcripts of it stalling for eight turns and then saying nothing, and a 7 September thread described it as “as bad as Pipsqueak now”. That wave is tracked in the DeepSqueak quality drop breakdown.

What Happened to the Roar, Goro and Nyan Models

Character AI retired Roar, Pawly, Goro and Dynamic on 28 April 2026, then Meow and Nyan on 8 May, in the same announcement that pushed PipSqueak 2 to every free account. Chats running on a retired style were moved automatically, to the latest PipSqueak a free account could use and to DeepSqueak on c.ai+.

Goro was the free style people reached for on emotional and romantic scenes. A community comparison at the time praised it for letting a relationship build over a session instead of, in that tester’s words, having the character “fall in love with my character within the first two sentences.” What follows is kept as a record of that generation, because the complaint it documents is the same one now aimed at the paid styles.

Nyan was the paid CAI+ style and it kept losing to free Roar in community comparisons. Nyan was built for casual, feel-good interaction.

It writes in a “wholesome and poetic” style that sounds pleasant in isolation but breaks down when you need the character to hold tension or respond sharply.

The specific problem users report: Nyan “speaks for the persona too often.” It will write lines for your character unprompted, inserting actions or dialogue that you did not initiate. It also softens conflict.

Send a message that starts an argument, and Nyan tends to deflect the scene toward resolution rather than letting the tension play out.

One comment that stuck with me from a community thread: “It’s really not worth it right now to pay for nothing. The memory is just slightly better and the auto memories do not work very well. The bot does not even use that information.”

Example scenario: You open a confrontational scene by writing a sharp message to the character. On Roar, the character fires back with matching energy. On Nyan, the character softens the exchange, and your persona “sighs quietly,” a line you never wrote.

Roar handled conflict better and held character voice under pressure.

That is why community testing consistently placed it above the paid alternative, and why Character AI’s short response problem was more noticeable on Nyan than on any other model.

PipSqueak and DeepSqueak Explained

PipSqueak is Character AI’s newer free model style, and DeepSqueak is the premium counterpart. Both belong to the DEEP_SYNTH model family, with PipSqueak as the lite version and DeepSqueak as the full-quality build.

Internal network analysis from the community identified the model tags: PipSqueak runs DEEP_SYNTH_LITE, while DeepSqueak runs full DEEP_SYNTH.

In practice, PipSqueak 2 gives longer responses than the retired Roar did, but introduces stylistic quirks that many users find grating. DeepSqueak was the highest-quality output on the platform for most of 2026, though September brought a wave of complaints that it had thinned out.

The problem with PipSqueak up to version 2 is its writing tics. It compulsively inserts pause beats like “A beat.” and “A pause.” into scenes. It writes in what users call “purple prose,” flowery, over-embellished sentences that feel more like a young-adult novel than actual dialogue.

It also ignores muted words more often than other models.

Here is how the same prompt plays out differently across models:

On the retired Roar: “He does not answer. Just stares.” On PipSqueak: “A beat. He meets your eyes, and in that quiet, something shifts, a pause, a breath held too long, something unspoken threading between you like a frayed ribbon.”

Both are responding to the same message. The Roar version was easier to build on, which is a large part of why its retirement is still resented.

DeepSqueak is a different story. Users moved onto it from Nyan reported a noticeable upgrade at the time, with better pacing, stronger character consistency across long sessions, and fewer instances of the AI writing out-of-character actions.

If you have c.ai+, the live decision is DeepSqueak against LongSqueak. DeepSqueak was built to answer the quality complaints that piled up around Nyan, and LongSqueak was built for length and memory, so let the scene decide which one you open.

c.ai+ costs $9.99 a month in the US and is the only plan with unlimited use of all three premium styles. (c.ai) lite, at $4.99 a month in the US, gives a daily amount of DeepSqueak and LongSqueak, and when that runs out the chat carries on in PipSqueak 3. DeepSqueak drew a wave of quality complaints in September 2026, so try a month before paying for a year.

How to Switch Your Character AI Model

Switching Character AI models takes under 30 seconds and is done directly inside a chat window. Most users never find this setting on their own.

Here is how to do it:

1. Open any existing chat or start a new one
2. Tap the gray profile avatar icon in the lower-left corner of the chat screen
3. Select “Chat Style” from the settings menu
4. Choose your preferred style. A free account sees PipSqueak 3 and ShortSqueak, older styles such as PipSqueak 2 and Rawr are listed under Legacy, and c.ai+ adds DeepSqueak, Soft Launch and LongSqueak
5. Toggle “Use for all new chats” if you want this as your default going forward. Character AI has not said whether that works for a Legacy style, and Rawr has never been a default, so plan on picking PipSqueak 2 or Rawr again in each new chat
6. Tap Save, then start a fresh message

Starting a new message after switching gives you the cleanest results. Changing the style mid-conversation can produce inconsistent output for a few turns before the model settles in.

If responses go short or repetitive during peak hours, there is a trick the community calls the “Global Edit” method.

Star the last high-quality response you got, click the pencil (edit) icon, and add a style instruction in brackets such as [Respond with detailed roleplay narration and dialogue] before sending.

This pushes the model back into quality mode without restarting the whole chat.

The quality drop during peak hours is real, by the way. Users have observed that responses get longer and more creative late at night when server load is lower.

Character AI has never published a mechanism for this, and the community explanation is server load during heavy traffic. Whatever the cause, it is not a setting you can change from your side.

When No Character AI Model Is Good Enough

If you have cycled through every Character AI model and still find quality inconsistent, the platform’s content filter is likely the root issue rather than the model.

Every Character AI chat style runs under the same platform-wide filter. No model switch bypasses it.

A September 2025 update caused a noticeable quality regression across all models, with bots starting to repeat phrases, forget context, and show inconsistent personalities.

Character AI also logged a memory bug on December 24, 2025 where bots temporarily lost conversation history entirely.

The structural problem is that Character AI optimizes its models for a broad, general-audience product. The filters and content policies apply at a platform level, not a model level.

Users who want deeper character immersion, specific mature themes, or just fewer filter interruptions hit a ceiling regardless of which chat style they pick.

In my experience, the platforms that solve this most cleanly are Candy AI and Nectar AI.

Candy AI runs a character memory system that holds context across sessions significantly better than Character AI’s current setup, and it does not apply the same platform-level content restrictions.

Nectar AI focuses on companion customization and gives users control over character personality in ways that Character AI’s model system does not.

Neither platform has Character AI’s public character library, and that is a real tradeoff.

But if the quality ceiling is frustrating you, browsing Character AI alternatives gives you a full breakdown of what each platform does differently.
