Open AI ASTRA Update + Possible Fable 5.1 and GLM 5.5 Drop!?
Astra didn’t drop yesterday — but something else did. A mysterious new AI model called **Ox Alpha** just appeared on OpenRouter completely free, with a **1M+ token context window**, image and video input, tool calling, and a heavy focus on coding and long-running agentic tasks. At the same time, rumors are circulating that OpenAI may be holding Astra while Anthropic prepares **Fable 5.1**. But how much of that is actually confirmed? In this video, I break down: * What actually happened with Astra * Whether Astra was really “delayed” * The Fable 5.1 / Anthropic rumors * What OpenAI has officially said about slowing frontier model development * The mysterious Ox Alpha model * Why people think Ox Alpha may be related to GLM * Ox Alpha’s massive 1M-token context window * Why you should be careful before uploading private code to anonymous free models Section breakdown: - 0:00 — Astra misses Thursday - 0:58 — What Ox Alpha is and how to use it - 2:13 — Data-retention warning - 2:42 — Why people suspect GLM - 4:10 — Astra versus Fable 5.1 - 5:10 — Codex limits and your subagent workflow - 6:07 — Tibo’s reset update - 7:08 — Why OpenAI may have hit the brakes - 7:58 — What is actually known about Fable 5.1 - 8:41 — GPT-5.7 versus GPT-6 - 9:40 — Final verdict Astra “couple of weeks” + Anthropic waiting on Fable 5.1 These closely track the leak described in the video: Main scoop post (OpenAI told employees Astra in a couple of weeks + demos of real-world tasks; updated checkpoint being dogfooded in Codex; Anthropic sitting on Fable 5.1 until Astra launches): https://x.com/synthwavedd/status/2090438712610242609 Follow-up / Chinese coverage of the same leak: https://x.com/MetaEraCN/status/2090645277510185176 Another summary of the same info: https://x.com/NFT_Chen/status/2090492730376122751 Posts saying Anthropic is holding Fable 5.1 and waiting for Astra (targeting early-mid September): https://x.com/JoraiLaurenceo/status/2090789400342913264 https://x.com/vepsi__/status/2090725993619009997 https://x.com/pankajkumar_dev/status/2090715870851186970 Codex / ChatGPT limits reportedly cut in half (Nerf Track, Plus/Pro quotas) Reddit-style report that NerfTrack showed Plus weekly API-value limit dropping ~$160 → ~$80, with Pro 5x/20x quotas burning in 1–3 days: https://x.com/CryptoEights/status/2090770903013413163 (quotes the original summary) Users complaining limits feel drastically reduced / halved and calling out Codex team: https://x.com/kkk596022167059/status/2090815665900798298 https://x.com/kkk596022167059/status/2090815192548491418 https://x.com/JayDook/status/2090819742546137231 https://x.com/imosvaldoe/status/2090819825945739371 https://x.com/imosvaldoe/status/2090819411376476248 Ox Alpha stealth model on OpenRouter Lots of testing and speculation (Xiaomi/MiMo, GLM-5.3-Flash, etc.): Strong performance claims and speculation (MiMo / GLM / others): https://x.com/luckeyfaraday/status/2090819814524678286 https://x.com/matt_kaschel/status/2090819359857918240 Claims it’s GLM-5.3-Flash / Zhipu (with fingerprinting): https://x.com/NFT_Chen/status/2090818860945649737 https://x.com/RocketmanSh/status/2090817525692903667 Ongoing discussion / identity debate: https://x.com/shitunote/status/2090819760007057670 https://x.com/omarsar0/status/2090820040073322733 Subscribe for AI news, new models, coding agents, OpenAI, Anthropic, DeepSeek, GLM, Codex, Claude Code and everything happening in the AI race. 🔔 SUBSCRIBE TO BYTEFORWARD: https://www.youtube.com/channel/UCGGHPOAzUaKsSc2yjsOeAFQ?sub_confirmation=1 #AI #OpenAI #Astra #OxAlpha #ArtificialIntelligence #ChatGPT #Anthropic #Claude #GLM #OpenRouter #AITools #AINews #CodingAI #AIAgents #GPT6
