Ox Alpha is an anonymous frontier-class AI model on OpenRouter and OpenCode: 1M-token context, video input, free for roughly a week. The specs, early tests, identity theories, and how to try it safely.
Grok and Gemini serve different surroundings — xAI’s real-time angle vs Google’s ecosystem. How to test them on your own tasks instead of trusting benchmarks.
DeepSeek V4-Flash-0731 is an official, open-weight, MIT-licensed MoE model with a 1M-token context, tuned for agents and coding, at about $0.14 per million input tokens. Specs, benchmarks, and why open weights plus low prices pressure the closed labs.
Claude Mythos 5 is Anthropic’s restricted-access Mythos-class model — the same underlying model family as Fable 5 but with fewer safeguards and stricter access controls. It is limited to approved Project Glasswing and trusted-access partners. This guide covers what Mythos 5 is, how access works, benchmark data, safety design, and when Mythos-class capability matters versus Fable 5 or Opus 5.
A head-to-head comparison of Claude Opus 5 and Claude Sonnet 5: benchmark deltas, pricing tiers, feature differences, and a practical decision framework. Opus 5 leads on complex reasoning and agentic coding; Sonnet 5 delivers strong everyday performance at lower cost. Includes use-case breakdowns, competition context, and FAQ.
Every Claude model and pricing tier in one guide. API pricing for Fable 5 ($10/$50), Opus 5 ($5/$25), Sonnet 5 ($3/$15 intro $2/$10), and Haiku 4.5 ($1/$5) per MTok. Subscription plans from Free to Enterprise. Prompt caching, batch API, fast mode, and cross-provider comparisons — all verified July 25, 2026.
Polymarket reports Grok 4.5 has overtaken GPT-5.6 Sol and Fable 5 in OpenRouter token volume, cracking the top 10 closed models. The milestone measures usage, not quality — but it lines up with a genuinely aggressive value proposition: $2/$6 per 1M tokens, roughly 2x token efficiency, 80 TPS, a SWE Marathon lead, and Cursor-co-trained coding performance. Here is what the signal means, what xAI’s benchmarks show, and what they do not.
Black Forest Labs launched FLUX 3 on July 23, 2026, in Early Access. Unlike FLUX 1 and FLUX 2, which generate images, FLUX 3 is a single multimodal flow model trained jointly on images, video, and audio — and even robot actions. It generates video with native audio up to 20 seconds, and an early version already powers FLUX-mimic, a video-action robotics model deployed at Audi. Here is what FLUX 3 does, what is still preliminary, and what the rollout plan covers.
Sakana AI shipped Fugu-Ultra v1.1 on July 24, 2026, refreshing its multi-agent orchestration model with newer frontier workers. Sakana claims up to 7.9 benchmark points over v1.0, with the biggest gains on ProgramBench and Terminal Bench 2.1, and keeps pricing identical to v1.0. Here is what changed, what is still vendor-reported, and how to evaluate the upgrade.
Claude Opus 5 launched July 24, 2026. It delivers near-Fable 5 intelligence at Opus pricing ($5/$25 per MTok), with a 1M-token context window, 128K max output, and state-of-the-art results on Frontier-Bench, ARC-AGI 3, and OSWorld 2.0. This guide covers benchmarks, pricing, safety, access, and how Opus 5 compares to Fable 5, Sonnet 5, and the competition.
