Fireship

Summary

This video breaks down the surprise release of OpenAI's GPT-5.6 family, including the flagship 'Soul' model. It explores the new government-mandated review process for AI models, the shift toward agentic workflows that spawn sub-agents for parallel tasks, and how these models compare against Anthropic’s Claude models. The host provides an honest assessment of performance, potential cheating in benchmarks, and the trade-offs between speed, cost, and accuracy when choosing between the leading AI tools currently available.
