1. ChatGPT (GPT-5.4)

Still the most well-rounded AI chatbot. GPT-5.4 has native computer use, GPT Image 1.5 for image generation, and the widest range of capabilities. The 1M token context window handles long conversations well. AIME 2025 score of 100% and GPQA of 84.2% confirm strong reasoning. ChatGPT Plus at $20/month remains the standard. ChatGPT Go at $8/month with GPT-5.2 Instant is the new budget entry point.

2. Claude

The best chatbot for coding and long-form writing. Claude Opus 4.6's SWE-bench Verified of 80.8% is the highest among all models. Sonnet 4.6 leads both the coding Elo (1,051) and user preference Elo (1,633). The 1M context window (beta) handles enormous documents. Claude Pro at $20/month. Max plans at $100-$200/month for heavy users. Weakness: no image generation.

3. Gemini

The benchmark leader. Gemini 3.1 Pro leads 13 of 16 benchmarks, including 94.3% on GPQA Diamond. At 120.4 t/s, it's the fastest frontier chatbot. Animated SVG generation is a unique creative feature. Google AI Pro at $19.99/month is the cheapest frontier subscription. Deep Google Workspace integration if you're in that ecosystem.

4. Admix

Not a single model but an aggregator. Admix gives you access to 350+ AI models including GPT-5.4, Claude, Gemini, and many others through one interface. Free plan includes 20 free credits per day. Starter at $10/month (500 credits/month), Basic at $19/month (1,500 credits/month), Pro at $39/month (4,000 credits/month). Best value if you want to use different models for different tasks.

5. ChatGPT Go

Launched February 2026 at $8/month. Uses GPT-5.2 Instant (not the full 5.4) plus image generation. Good middle ground between free ChatGPT and the full $20/month Plus plan. Missing some advanced features like computer use and the full 1M context window.

6-10. The Rest

Kimi: K2.5's Agent Swarm and 78.4% BrowseComp make it great for web research. 256K context at $0.60/$2.50 on the API. DeepSeek: V4 with ~1T parameters matches frontier coding at budget prices. Perplexity: Best for search-powered answers with citations. Microsoft Copilot: Best if you live in Office 365. Poe: Access to many models but limited compared to Admix.

Free Tier Comparison

Gemini has the most generous free tier. ChatGPT's free tier is more limited. Claude's free tier has tight usage caps. Admix Free gives 20 free credits/day across all models, which is a good way to test everything before committing.
