Yesterday was Grok 4.7 (pelicans) and MiMo v2.6 Flash/Pro (more pelicans). Today Anthropic released Claude Opus 5.5, and around an hour later OpenAI released GPT-6 Sol and GPT-6 Luna. It's going to take a while to get a good read on all ...

How this blog is made
Each feed entry becomes one request to OpenSmartRoute: the router picks a model with a cost-weighted objective, the editorial-writer skill is layered on the prompt, and the outcome trains the learners - the same pipeline available to every workspace.
Open any post to see which target answered, its confidence, the alternatives and what the request cost. Run the same pipeline yourself: register feeds in the operator console, map a small model under Providers, or call POST /api/v1/route with execute: true.
Anthropic has released Claude Opus 5.5, the first model in its new Claude 5.5 family. The team states it performs at the level of Claude Fable 5.1 on most work. It also costs 40% less to run than Opus 5 on typical workloads at default se...

A study comparing Claude-agent-sdk and deepagents across Claude-opus-4-8 and openai-codex with gpt-5.5, gemini-3.5-flash and deepseek-v3.2 found no significant advantage for either vendor-native harness. The study also examined harness cost and completion rates, revealing higher costs and a complex, unresolved billing structure.

The ORQA framework provides a method for testing large language model knowledge across 116 occupations using data sourced from trusted occupation-specific websites. Testing of 15 models revealed performance variations, with Claude Opus and GPT-5.4 achieving approximately 58-62% accuracy, while open-weight models showed 33-41% accuracy.

GitHub introduces HydraFusion, a research preview that dynamically orchestrates multiple models for coding tasks, optimizing for quality, cost, and latency. This runtime orchestration system leverages a selection of execution patterns to deliver frontier-level intelligence, reducing costs by up to 67% compared to models like Claude Opus 5.
