🤖 Model Rankings
Anthropic's flagship model with 1M token context (beta), adaptive thinking, and the highest agentic coding scores. Introduced Agent Teams for parallel autonomous coding. Nearly doubled ARC-AGI-2 score over Opus 4.5 (68.8% vs 37.6%).
Anthropic's flagship model, widely recognized as the top coding model. Excels at complex refactoring, large codebase comprehension, and agentic coding. Claude Code makes it the go-to choice for professional developers.
OpenAI's most capable and efficient frontier model for professional work. Combines industry-leading coding with native computer use, 1M+ context window, and improved reasoning. First GPT model to beat human performance on desktop navigation tasks.
Anthropic's best value flagship, coding ability close to Opus at 1/5 the price. HN users praise its performance on daily coding tasks, popular choice for Cursor and similar tools.
OpenAI's unified flagship model with built-in routing system that auto-selects optimal sub-models. HN users praise its comprehensive multimodal capabilities and competitive pricing ($1.25 vs Claude $15). However, benchmark chart errors at launch sparked controversy.
GPT-5.4's reasoning variant with adjustable thinking depth. Replaces GPT-5.2 Thinking (deprecated June 2026). Supports four effort levels from 'low' to 'xhigh' for balancing speed vs reasoning depth. Available for Plus, Team, and Pro subscribers.
OpenAI's coding-optimized model, surpassing Claude on SWE-bench. HN users praise its coding value and much more generous quotas than Claude. Ideal for intensive coding work.
Google's most advanced Pro-tier model with 1M context, dynamic thinking, and the highest ARC-AGI-2 score (77.1%) among all models. Excels at multimodal reasoning across text, images, audio, and video. Best price-to-performance ratio among frontier models.
Google's comprehensive flagship with industry-leading 2M context window. HN users praise its strong multimodal processing and Google ecosystem integration. Some users believe it has surpassed OpenAI. Works well with Antigravity IDE.
Alibaba's flagship open-source MoE model with 397B total parameters (17B active per pass). Apache 2.0 licensed for commercial use. Supports 201 languages with native vision capabilities. Best open-weight model for local deployment.
Moonshot AI's open-source flagship with top HLE and Live Codebench scores. HN users praise its agentic coding ability approaching Claude Haiku 4.5, making it the coding king among open-source models.
Chinese AI rising star, priced at 1/100 of Claude. HN users praise its coding ability approaching top closed-source models with unbeatable value. Ideal for cost-sensitive scenarios and large-scale API calls.
xAI's flagship model with deep X (Twitter) integration. Strong real-time web search capabilities with a humorous and direct style. Ideal for scenarios requiring latest information and social media analysis.
Google's fastest and most cost-efficient Gemini 3 series model. 2.5X faster Time to First Token and 45% faster output than 2.5 Flash. Designed for high-volume workloads including translation, content moderation, UI generation, and simulations. Supports adjustable thinking levels.
