Anthropic's frontier model, currently first on the Artificial Analysis Intelligence Index
Added Aug 4, 2026
Claude Opus 5 is Anthropic's flagship model, released 24 July 2026 with a 1M-token context window and five selectable effort levels (low, medium, high, xhigh, max). Effort is the main control: output token spend runs roughly 8x from low to max, and Artificial Analysis measures a 407-Elo spread in task quality across that range, so the same model behaves like several different price and capability tiers. API pricing is $5 per million input tokens and $25 per million output, with cache writes at $6.25 and cache hits at $0.50. It leads the Intelligence Index at 60.7 and tops the Coding Agent Index, scoring 89 percent on Terminal-Bench v2.1 at max effort and 53 percent on Humanity's Last Exam.
Why: It is the current number one on the independent Artificial Analysis Intelligence Index, and it got there while costing less per task than the model it displaced: $2.03 average per index task against Fable 5's $2.75. The effort dial is the reason to pick it over a fixed-tier model, because one integration covers cheap high-volume calls and expensive long-horizon agent runs.

The Efficiency Revolution: Frontier Intelligence at 1/100th the Cost
Added Feb 5, 2026
DeepSeek is the architect of the 'DeepSeek movement,' a fundamental shift in AI development that prioritizes extreme efficiency over raw compute. Founded by High-Flyer Quant, they proved that architectural innovations like Multi-head Latent Attention (MLA) and DeepSeekMoE could match the performance of $100B models like GPT-4o and Claude 3.5 while costing 95% less to train and run. Their ecosystem includes the flagship DeepSeek-V3, the reasoning-heavy DeepSeek-R1, and the state-of-the-art DeepSeek-VL2 for high-fidelity OCR and vision tasks. DeepSeek is committed to the open-source community, regularly releasing model weights and technical papers that have democratized frontier-level AI for developers globally.
Why: DeepSeek changed the game by proving that 'expensive' doesn't always mean 'better.' We picked it because it's the first model family to offer true frontier-level reasoning (R1), general intelligence (V3), and advanced vision/OCR (VL2) with an open-weight philosophy and an API price point that makes proprietary models look obsolete.

DeepSeek's current Flash model: a 552B multimodal MoE with MIT weights and a 1M context
New this month Added Oct 17, 2026
DeepSeek-V4.1-Flash is DeepSeek's efficient multimodal model. The line launched September 10, 2026, and the October 17 checkpoint, V4.1-Flash-1017, is the one on the website, the app, the API and Hugging Face. DeepSeek describes a 552-billion-parameter mixture of experts with 8 billion parameters active on input and 16 billion on output, native image understanding, and a context of up to 1 million tokens. Call it as deepseek-flash. The older names deepseek-v4-flash and deepseek-v4-flash-vision-exp route to this model. Weights are under the MIT licence. DeepSeek says the October 17 update improves reasoning, coding, agent and vision results and shortens outputs, without a price change.
Why: The DeepSeek API name most people already use now serves this model, and the weights are public. It is the Flash model the independent index lists, which the older V4-Flash entry no longer is.

The 'Next DeepSeek' Movement: o1-Level Reasoning at 1/100th the Cost
Added Jan 31, 2026
Kimi k1.5 is a multimodal large language model from Moonshot AI, specifically engineered for high-fidelity technical reasoning and long-context processing. It is a key player in the 'DeepSeek movement,' matching the reasoning performance of frontier models like GPT-5.2 Codex and Claude 4.5 while remaining significantly more cost-effective. It features a massive 2 million token context window and joint text-vision reasoning, making it ideal for complex coding, mathematical proofs, and large-scale document analysis. The model is built using advanced Reinforcement Learning (RL) to achieve deep 'Chain-of-Thought' capabilities.
Why: Kimi k1.5 is the first model to prove that o1-level reasoning is achievable through efficient, open-weight architectures. We selected it because it consistently matches or exceeds Claude 4.5 in technical benchmarks (AIME, MATH-500) while offering a 2M context window and a significantly lower API price point, making frontier intelligence accessible to everyone.
