Clear notes on new frontier models, API availability, and what each launch means for builders who want one stable integration.
DeepSeek V4 Flash brings 284B total parameters, 1M context window, and ultra-low prompt caching costs. MuiRouter supports it via API and Playground with pay-as-you-go pricing.
OpenAI abruptly slashed prices for GPT-5.6 Luna by 80% and Terra by 20%. Here is a breakdown of developer consensus, cost-per-task model routing, and strategic analysis.
Claude Opus 5 approaches Fable 5-class coding and knowledge work at Opus 4.8 pricing. Community early takes focus on cost-performance; MuiRouter now supports claude-opus-5.
Kimi K3 combines 2.8T parameters, a 1M-token context window, native vision, and max thinking. MuiRouter now supports it through the API and Playground with one API key.
OpenAI launched GPT-5.6 on July 9, 2026 across ChatGPT, Codex, and the API: flagship Sol, balanced Terra, and cost-efficient Luna. Here is what shipped, the new pricing tiers, and what it means if you build with AI.
xAI shipped Grok 4.5, a new flagship trained alongside Cursor and benchmarked against Claude Opus 4.8, then landed Grok on Cloudflare AI Gateway. We've added grok-4.5, grok-4.3, and grok-imagine-image to the MuiRouter catalog — here's what shipped and how to start using it.
Codex degradation is better understood as a probability problem plus a context problem. Here is why optional commentary can make agent loops worse, why a clean new thread often works, and how to decide when to reset.
Anthropic released Claude Sonnet 5 on June 30, 2026, pricing agentic coding and tool-use performance close to Opus 4.8 well below Opus rates. Here is what shipped, what independent reviews and benchmarks say, the pricing catch worth knowing about, and what it means if you build with AI.
Anthropic released Claude Fable 5, the public, safety-routed version of its Mythos-class frontier model. Here is what shipped — two-tier Fable 5 / Mythos 5, a classifier-plus-Opus-4.8 fallback, and $10/$50 pricing — and what it means if you build with AI.
OpenAI has released GPT-5.5 for ChatGPT and Codex, with stronger agentic coding, computer use, knowledge work, and research capabilities. Here is what changed and how to prepare for API access.
