🧠 AI Models
Large language models optimized for coding tasks. Compare performance benchmarks, context windows, and specialized capabilities.
Claude Fable 5.1
Frontier AI
The new performance ceiling 🆕 — enters at #1 with 1762 Elo, 73 points above Fable 5. Cache reads drop 75% to $0.25 per million tokens, cutting real-world cost by roughly 25% on typical workloads and up to 45% on agentic tasks. Mandatory data retention is gone. Cyber safeguards fire around 60% less often. The strongest coding model available today.
Claude Opus 5
Premium AI
The balanced frontrunner ⬇️ — Opus 5 drops to #2 after Fable 5.1 outscored it by 74 Elo points. At 1688 Elo and unchanged $5/$25, it remains the best price-to-performance ratio at the frontier. No data retention requirement, 1M context. First recommendation for teams that cannot justify Fable's $10/$50 base rates.
Claude Opus 4.8
Premium AI
Strong performer with 1M context, 128K output, Agent Teams, and adaptive thinking. Stable at high Elo score on WebDev Arena. Proven for agentic workflows.
Claude Opus 4.6
Premium AI
The proven performer — 1M context, 128K output, Agent Teams, adaptive thinking, and the deepest MCP ecosystem. Stable at 1536 Elo on WebDev Arena. Stable workflows have no urgency to migrate.
Claude Opus 4.7
Premium AI
The proven performer ⬇️ — drops from #1 to #5, displaced by its own successor and Fable 5. At 1557 Elo it is only 4 points below Opus 4.8 on the same $5/$25 pricing, making the upgrade path obvious. Expect this to exit the top 5 next month as adoption shifts to 4.8.
Claude Sonnet 5
General Purpose AI
The accessible powerhouse — 1M context window with strong performance at $2/$10 Sonnet pricing. Best value in the Claude lineup with near-Opus performance on many tasks.
DeepSeek V4 Pro
Open Source AI
The pricing earthquake — matches frontier performance at 34x cheaper. $0.435/$0.87 per 1M tokens with permanent pricing since May 22. Cache-hit input at $0.003625. Full quality profile of models costing 10-30x more.
Gemini 3 Pro
Multimodal AI
Full video processing and 24-language voice support. Tiered pricing at $2/$12 (<200K tokens) and $4/$18 (>200K tokens).
Gemini 3.1 Pro
Multimodal AI
The efficiency champion with tiered thinking levels (Low/Medium/High). Full multimodal with 24-language voice, video processing, and native capabilities.
GLM-4.6
Open Source AI
Open-source coding model with full multimodal capabilities including voice, image, and video processing. Strong for Chinese language development.
GLM-5
Open Source AI
The open-source leader with MIT license, self-hostable on vLLM/SGLang/Huawei Ascend. 744B MoE architecture (40B active per token). Strongest open-source value play at frontier performance.
GPT-5.2
General Purpose AI
The balanced performer with solid reasoning and massive 400K context window.
GPT-5.4
General Purpose AI
OpenAI's first model combining frontier coding, native computer use, and knowledge work. Introduces Tool Search cutting token usage by 47%.
GPT-5.5
General Purpose AI
The autonomous workhorse — Terminal-Bench 2.0 leader with strong autonomous reasoning. WebDev Arena score holds steady with consistent performance across knowledge work and coding tasks.
Grok 4.6
Specialized Coding AI
The free-tier frontrunner ⬇️ — Grok 4.6 drops to #5 as its score settled from 1630 to 1625. Now shares the $2/$6 price point with Qwen 3.8 Max but trails it by 61 Elo points with a smaller 500K context. Its edge is the free tier and day-one availability across Cursor, Grok Build, and major gateways.
Grok 4.3
Specialized Coding AI
Always-on reasoning with native tool use and full video input (mp4/mov/webm, 5 min at 1080p). One of only six models with full video processing.
Kimi K2.5
Agentic AI
Open-source with full video processing, native multimodal capabilities, and Agent Swarm enabling up to 100 sub-agents. Fast context retrieval with 256K context window.
Kimi K3
Agentic AI
The open-weight standard ⬇️ — Kimi K3 holds at 1674 Elo but drops two spots as new entrants passed it on raw score and value. At 2.8T parameters, 1M context, and self-hosting under the Kimi K3 License, it remains the strongest open-weight model on this list. The drop is purely positional.
Kimi K2.6
Agentic AI
Leaps to #8 on WebDev Arena with 300-agent swarms and 12-hour autonomous sessions. Open-weight with Modified MIT licensing, undercutting every closed frontier model.
Llama 4 Maverick
Open Source AI
Meta's latest open-source model with native early fusion multimodal and 200-language support.
Qwen 3.8 Max
Agentic AI
The multimodal value play 🆕 — Qwen 3.8 Max (0902) enters at #3 with 1686 Elo (preliminary) at $2/$6, the cheapest model in the top five. 2.4T parameters, 95B active, 1M context, native text, image, and video input. Open weights available for the 27B variant (Apache 2.0). First Alibaba model in the top three. Always-on reasoning inflates effective per-task cost.
Qwen 3.7 Max
Agentic AI
The agent-first dark horse ↔️ — holds its spot but its WebDev Arena score settled, now below Opus 4.6. The value case at $2.50/$7.50 remains strong. Still text-only with zero vision input. Alibaba demo ran 35 hours autonomously with 1,158 tool calls.
