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.
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.
Google has started what it calls its most ambitious pre-training run yet for Gemini 4, but has not announced a release date, model lineup, benchmarks, pricing, context window, or public preview.
Google’s July 21 Gemini update adds a more token-efficient 3.6 Flash, a 350-token-per-second 3.5 Flash-Lite, and the restricted Gemini 3.5 Flash Cyber model for CodeMender.
Anthropic’s new Record a skill command lets paid Claude users demonstrate a task on screen, explain decisions aloud, and convert that demonstration into a reusable Cowork workflow.
A source-checked guide to Qwen3.8-Max-Preview covering release status, 2.4T scale, context and output limits, reasoning controls, Qwen Cloud pricing, early coding evidence, and the promised open-weight release.
