In 2026 there is no single "best AI model" - there is a best model for this task. Claude Fable 5 owns the Arena leaderboard. GPT-5.6 Sol wins on agent coding. Qwen3.7 Max is the strongest Chinese-first model and the best value. ChatGPT Image 2 and nano-banana-2 split image generation. Veo 3.1 and Kling 3.0 split video. Suno V5 and ElevenLabs split audio. x-rush.ai connects to these top-tier models and routes each task to the one that fits best - and when the next one ships (2026 ships one almost every month), we connect it too.
This page is the quick-reference: what each model is good at, what it costs, and when x-rush picks it. For the routing architecture itself - the three-layer design, gateway failover, and how we compare to OpenRouter and Portkey - see Smart Routing Explained.

Read the table as a menu, not a ranking. The "best" row depends on what you typed. The pool is wider than this - Gemini 3.5, DeepSeek V4, Grok 4.5, Seedance 2.0 and others are connected too - but these nine are the ones x-rush reaches for first.
Text Models
Claude Fable 5 (Anthropic) - the Mythos-class flagship, $10/$50 per million tokens, 1M context. Arena #1 at Elo ~1509, Artificial Analysis Intelligence Index ~60, SWE-Bench Pro 80.3%. The model x-rush routes to for long-form reasoning, deep codebase refactors, and anything that needs the model to "get" what you didn't say out loud.
GPT-5.6 Sol (OpenAI) - $5/$30, half the price of Fable 5, Terminal-Bench 2.1 88.8% (91.9% in Ultra). The default for agent loops, terminal work, and high-volume coding where Fable 5's price would bite. The speed dial - Fast, Max Reasoning, Ultra - lets x-rush pick fast-and-cheap for simple tasks and slow-and-deep for hard ones.
Qwen3.7 Max (Alibaba) - $1.25/$3.75, the price-performance king and the strongest Chinese-first model. Artificial Analysis #5 globally, #1 domestic, Code Arena 1541 (#4 worldwide). x-rush routes Chinese copy, bilingual content, and long autonomous agent runs (it sustains 35-hour multi-step tasks) here.
Image Models
ChatGPT Image 2 (OpenAI) - Arena T2I #1 at Elo 1512, 242 points ahead of #2. Best at rendering readable text inside images (posters, UI mockups, infographics), following multi-constraint prompts, and Chinese cultural nuance. ~$0.06-0.08 per image. The default for anything with words in it.
nano-banana-2 (Google, Gemini 3.1 Flash Image) - $0.067 per 1K image, half the price of Nano Banana Pro, Arena T2I #2 at Elo ~1280. Native 4K, Flash-tier speed (under 1.5s), up to 5 consistent characters per workflow. x-rush routes high-volume batches and 4K needs here - same quality, half the cost.
Video Models
Veo 3.1 (Google DeepMind) - $0.05-0.15 per second, the only top model that generates native audio with the video. Best for dialogue, phoneme-accurate lip-sync across 8+ languages, and talking-head scenes. 30s clips, 1080p default. Pick it when a human needs to talk on camera.
Kling 3.0 (Kuaishou) - ~$0.03-0.15 per second, ELO ~1243 and #1 on most blind-test boards. Up to 5-minute clips at 4K with native audio, and the most consistent character faces across cuts. Pick it for cinematic B-roll, multi-shot storytelling, and longer narratives.
Audio Models
Suno V5 - $8/mo Pro, the S-tier for full songs with vocals. 50 credits/day free, and vocals that are hard to tell from human. x-rush routes song and BGM generation here.
ElevenLabs - $9.99/mo for Music (voice cloning from $5/mo). Voice Arena #1 for TTS and cloning, with 100% licensed training data for music via Merlin and Kobalt. x-rush routes voiceover, voice cloning, narration, and royalty-clean music here.
When x-rush Routes Automatically
For most users, automatic routing delivers the best result - you describe the task, x-rush picks the model, and you never have to know which one ran. The model pool follows the frontier: when the next Fable or GPT ships, we connect it. Override routing when you:
- Have a specific model preference
- Need consistent style across outputs
- Have compliance requirements
- Are testing and iterating on prompts
