Composer 2.5 vs SkyClaw-v1.0

The article discusses Cursor's release of the Composer 2.5 model, claiming it is currently the best coding model with excellent performance and cost-effectiveness.

The "smart, fast, cheap" trilemma limitation of AI models has been broken by Cursor's Composer 2.5, which can simultaneously achieve all three characteristics.

Cursor has released an SDK supporting Python and TypeScript for building custom AI agents using Composer 2.5, offering a 90% discount on Composer usage during a limited-time promotion.

The Cursor team achieved Composer 2.5 through reinforcement learning training rather than prompt engineering, with their large-scale RL program running inference on Fireworks, indicating that self-trained models will be the only way to maintain competitive moats after 2027.

Cursor released Composer 2.5, using Kimi as a base with 85% compute for self-training. It matches Claude Opus 4.7 performance at 1/10th the cost via targeted RL and 25x synthetic data.

The Cursor SDK now supports programmatic access to Composer 2.5's frontier intelligence features via Python and TypeScript, allowing developers to build their own AI agents with 90% discount during the long weekend.

Composer 2.5 is having a moment. Worth a look at how the team actually got here.

Cursor's self-developed coding model Composer 2.5 matches Opus 4.7 performance with less than 1-point score gap, but costs 10-30x less: input tokens drop from $15 to ~$1.5 per million, output from $75 to ~$2.5. It shows clear improvements over Composer 2 in long-context tasks, complex instruction following, and collaboration smoothness.

国产Agent模型SkyClaw-v1.0及其轻量版SkyClaw-v1.0-lite性能达到全球第一梯队，价格仅为主流模型的一半，且支持主流Agent框架和OpenAI接口。

The SkyClaw-v1.0 model has gained widespread attention since its official launch. A sharp increase in platform visits and API calls has led to service congestion. Skywork is taking measures to ensure the stability of their overall services and optimize performance.

SkyClaw-v1.0 是一个低成本的百万上下文代理模型，适用于复杂工具使用和多轮代理工作流。

SkyClaw-v1.0 is now officially supported in nanobot, enabling users to integrate via configuration docs with API key insertion. It offers enhanced tool usage and multi-turn task execution capabilities.

Skywork 现已由 SkyClaw-v1.0 驱动，增强推理能力和多轮执行能力。

Skywork_ai announces free access to SkyClaw-v1.0 through Apifree accounts, enabling developers to integrate the AI model via a unified API platform.

Skywork announces SkyClaw-v1.0, an agent model optimized for OpenClaw, Hermes, and Nanobot, featuring stronger tool use and multi-turn task execution capabilities, alongside a lighter variant SkyClaw-v1.0-lite, though technical details and performance metrics remain undisclosed.
