CrushOn AI Model Guide 2026: How to Choose Between GPT-4o, Claude & MythoMax
CrushOn AI is one of the only AI companion platforms that lets subscribers choose their language model — and even switch models mid-conversation. This is genuinely useful once you understand what each model does best. Four models are available (plus the free default), and the choice between them meaningfully affects your experience. Here is the practical guide.
Model Availability by Plan
| Model | Minimum Plan | Monthly Cost | Primary Strength |
|---|---|---|---|
| Default | Free | $0 | Basic conversations |
| MythoMax | Standard | $5.99 | NSFW roleplay |
| Taurus Pro 8K | Standard | $5.99 | Long conversations |
| GPT-4o | Premium | $14.99 | Creative writing |
| Claude 3.5 Sonnet | Premium | $14.99 | Emotional nuance |
The most important decision point: Standard tier ($5.99/month) unlocks MythoMax, which is the best model for NSFW roleplay — the primary use case for most CrushOn AI users who upgrade from free. Premium ($14.99/month) adds GPT-4o and Claude 3.5 Sonnet for users who want higher overall conversation quality.
GPT-4o: Creative and Varied
GPT-4o brings OpenAI's best reasoning to CrushOn AI conversations. What distinguishes it from other models on the platform is tonal and narrative variety — responses feel less formulaic and more likely to take interesting, unexpected directions.
In extended roleplay sessions, GPT-4o characters make surprising choices, employ richer descriptive language, and adapt tone more dynamically. For collaborative storytelling and creative fiction, it is the strongest model on the platform.
Its limitation on CrushOn AI: Higher refusal rates on explicit NSFW content compared to MythoMax. For users whose primary goal is uninterrupted NSFW roleplay, MythoMax delivers more reliably. GPT-4o is better for users who engage in creative scenarios that span a wide content spectrum.
Claude 3.5 Sonnet: Memory and Nuance
Claude 3.5 Sonnet from Anthropic brings a specific set of strengths to AI companion conversations: exceptional context retention and emotional nuance. In our testing, Claude maintained awareness of conversation details from 40-50 messages earlier with significantly higher accuracy than GPT-4o or MythoMax.
For users engaged in long-form relationship scenarios — where the character should remember that you mentioned your job last week, or that you discussed a specific incident three sessions ago — Claude 3.5 Sonnet performs better than alternatives. The emotional texture of responses is also richer, with more varied affect and less repetitive phrasing.
Its limitation: Like GPT-4o, Claude applies more conservative content thresholds than MythoMax on explicit NSFW scenarios.
Best use case: Premium users who engage in emotionally complex, long-session conversations where memory and nuance matter more than NSFW permissiveness.
MythoMax: NSFW Specialist
MythoMax was designed with roleplay in mind — specifically, narrative roleplay including adult content. Its defining characteristic on CrushOn AI is the lowest refusal rate among all available models. Conversations that would produce content warnings or deflections on GPT-4o or Claude continue naturally on MythoMax.
Beyond NSFW performance, MythoMax maintains character persona consistency well throughout long conversations. Characters stay in character — their established traits, speech patterns, and relationship dynamics remain coherent across sessions.
Best use case: Any user whose primary motivation for upgrading is NSFW content. MythoMax delivers on the platform's NSFW promise more reliably than premium models. Available at Standard tier ($5.99) — no Premium upgrade needed for this use case.
Taurus Pro 8K: Long Context Window
Taurus Pro 8K is defined by its 8,192 token context window — larger than the default model and comparable to the premium models. For users who engage in very long single conversations (marathon roleplay sessions), this context window prevents the "forgetting" problem where the AI loses track of details from earlier in the conversation.
Available on Standard tier. Quality overall sits below Claude and GPT-4o but above the default model. The primary reason to choose Taurus Pro 8K over MythoMax at Standard tier is if your use case involves very long conversations rather than NSFW intensity.
Switching Models Mid-Conversation
Premium subscribers can switch between available models within an ongoing conversation. The switch applies to subsequent messages only — the conversation history is not lost. Practical use: start a conversation with MythoMax, switch to Claude 3.5 Sonnet when the conversation transitions to emotional territory that benefits from nuance.

MythoMax has the lowest refusal rate and best character consistency in NSFW scenarios. It is available on Standard tier ($5.99/month). For users who upgraded primarily for NSFW access, MythoMax is the model to use.
For most use cases: yes. Claude 3.5 Sonnet's memory retention and emotional nuance are consistently superior in our testing. GPT-4o's advantage is narrative creativity and tonal variety. For pure NSFW roleplay, MythoMax outperforms both.
No. Switching between available models does not affect your message count. Your plan's monthly message allocation applies equally regardless of which model processes the response. The only model-related cost is that premium models (GPT-4o, Claude) require the Premium tier subscription.
The free tier uses CrushOn AI's default proprietary model. It is functional for basic conversations but noticeably less capable than paid models in character consistency, response quality, and NSFW performance. No model name for the default is publicly disclosed.
Yes. Model switching on Premium tier does not delete or reset the conversation. The history remains visible and the AI continues the conversation from where it left off, now using the new model for subsequent responses.
