Refreshed across 104 evaluated models. DeepSeek-V4-Pro-Max leads open source at 0.806, a ~14-point gap wider than the general-intelligence gap those same models show. Among models within 10% of the leader, Claude Opus 4.8 is cheapest at $5.00/Mtok input with 0.886, which is the practical price/performance pick for agent loops where you can't afford top tier on every call.

DeepSeek released V4 on April 24 and the numbers demand attention. V4-Pro is 1.6 trillion parameters total with 49 billion active, MIT-licensed, native 1M-token context. It scores 80.6% on SWE-bench Verified, putting it within 0.2 points of Claude Opus 4.6. On Terminal-Bench 2...
Here's the number that should change how you read every coding-agent ranking: 99 of 100 entries on the SWE-bench Verified leaderboard are vendor-submitted. One carries an independent verification badge. The other ninety-nine are labs grading their own homework on their own sca...
DeepSeek dropped V4 in mid-June as an open-weight model with a 1-million-token context window, priced at $1.74 per million input tokens, posting near-parity with GPT-5.4 on math and Q&A benchmarks (MindStudio). That's the headline number. The architecture underneath is more in...
This is the other half of the Fable 5 story, so read them together. While the best coding model in the world is uncallable, an open-weight one quietly posted frontier-adjacent numbers. Per Tom's Hardware, independent benchmarks for the MIT-licensed GLM-5.2 (744B params, 40B ac...
Alibaba released Qwen3.6-27B on April 22. Dense architecture. Open weights. 77.2% on SWE-bench Verified, within 3.7 points of Claude Opus 4.6. On SkillsBench, it scores 48.2% versus its own 397B MoE predecessor's 30.0%. That's a 77% improvement with 14.8x fewer parameters. Let...
OpenAI stopped reporting SWE-bench Verified scores. The reason: every frontier model has been trained on the dataset. Morph LLM published the numbers that explain why. Claude Mythos Preview scores 93.9% on the contaminated Verified benchmark. On the new, uncontaminated SWE-ben...
