Summary
IndyDevDan documents what he calls an “intelligence explosion” — more than five significant model releases within a single five-day window, including Kimmy K3, Deepseek V4 Flash, Deepseek V4 Pro, Gemini 3.7 Flash, Quinn 3.8 (27B), Grok 4.6, GLM 5.3, Iron 3.5 Lightning, and Muse Glimmer. He also notes that OpenAI slashed prices on Terra Luna and is testing 50% cuts on GPT 5.6 via Open Router, framing the moment as a full LLM pricing war that creates opportunity for engineers who can combine models strategically.
The core of the video demonstrates a “Fusion Harness” — a multi-agent orchestration setup that runs Fable 5, Gemini 3.7 Flash, and Deepseek V4 Pro simultaneously against real engineering tasks such as understanding DuckDB V2’s new features. Three commands are showcased: a debate mode that has agents argue competing positions, a collaborate mode where agents build on each other’s outputs, and a strategic decision-making mode for high-leverage calls.
On pricing, Dan highlights that Gemini 3.7 Flash at under $1 input and $4 output represents dramatic cost efficiency relative to frontier models, and flags a hidden cost trap in GPT 5.6: input prices double past the 280K token mark. He also argues that Opus 5 outperforms GPT 5.6 Soul on both quality and cost for many workloads, with a pointer to a prior video on system prompt engineering to tame Opus 5’s verbosity.
