We just got Fable 5-level coding at ~25× lower cost. Insane. DeepSWE: GPT-6 Luna Max: 66.6% Fable 5 Medium: 65.4% OpenAI reports 96% lower cost per task. I already loved Luna 5.6. As a daily coding-agent user, I’m thrilled to see this become so affordable.
GPT-6 Sol and Luna are out. Both are ~2× cheaper than 5.6, while Codex usage is only up ~40–50%. Luna looks especially good for the price. Sol improves on coding benchmarks, but 5.6 Sol still wins some OSWorld configs. Better and cheaper, just not everywhere.
Everyone is waiting for GPT-6 Sol. I’m waiting for Luna. GPT-5.6 Luna has been stupidly good for how cheap it is. If GPT-6 Luna actually drops today, I know what I’m testing first.
21 hours of benchmarking changed how I use GPT-5.6. Luna High: 14/30 verified Terra Medium: 10/30 Sol Low: 13/30 Terra ended up in an awkward middle. Luna gets more of my background work now; Sol stays for fast or messy tasks.
@TeamYouTube I can’t access YouTube live support, likely because I’m no longer Premium. I already cleared Google Play data, restarted phone, tried another device, signed in again, and I’m not using a VPN. I still get “We couldn’t verify your country.” That’s why I’m contacting you here on X.
@TeamYouTube I’m in Georgia but can’t subscribe to YouTube Premium: “We couldn’t verify your country.” Google Play Support checked my account and found no issue. I can’t reach Premium Support because I’m no longer Premium. Can you help?
I’m building my SaaS mostly with coding agents. Biggest unlock: give them ways to see what they’re doing — browser, logs, tests, runtime, docs, git. Once they can inspect their own work, the loop gets much better. I’ve had agents run ~10h and still land the task.
@danielfriklim01 My default stack: strict TypeScript + Biome, Knip for dead code, dependency-cruiser for cycles/boundaries, jscpd for duplication, OSV-Scanner for vulns, Vitest + Playwright for behavior. Next.js MCP + Chrome DevTools MCP for runtime/browser; Context7 + GitHub MCP for docs/code.
@shakhzod1001 Wow, man, impressive. Why you do all of that? Can I read you story somewhere?
China may not need to catch NVIDIA chip-for-chip. GLM-5.3-Flash is 320B, but only 18B are active. It cuts attention compute ~3× and KV cache ~4.4×. And GLM helped optimize its own serving stack. The hardware gap matters less when you redesign the workload.
Most coding-agent mistakes aren’t reasoning failures. They’re missing feedback. 4 MCPs I use to fix that: Context7 → current docs GitHub → real code + issues Next.js DevTools → runtime state Chrome DevTools → browser, network, console Fewer guesses. More ground truth.
100,000 free web-search API requests. Every month. Not a trial — it resets monthly. KeenAble just launched, and if you’re building AI agents, research tools, or anything search-heavy, this is a ridiculous amount of free infra. Use it while they’re giving this much away.
⚡Meet Qwen3.8-Flash, a multimodal MoE and an early preview of the Qwen4 architecture, now open-weight! The production version Qwen3.8-Flash will be available soon via QwenCloud API at just $ 0.16/1M input tokens and $ 0.47/1M output tokens. 125B parameters + 51B N-gram embeddings, with just 6B activated per token. Unmatched cost-efficiency. What's new: 🥳 - Next architecture: GDN + QSA hybrid attention, Gated Residual, N-gram Embedding & Muon optimizer, serving as a precursor to the architecture used in Qwen4. - Dramatically lower training and inference costs: trained at just 1/9 the cost of Qwen3.7-Plus, while outperforming it across the board with especially strong gains in coding and office tasks. - Strong performance: scoring 58.7 on DeepSWE 1.1, 62.5 on SWE-bench Pro, 73.9 on CoWorkBench, 84.5 on AndroidWorld, and 95.7 on MathVision (with CI). - 262K native context, extensible to 1M with YaRN. We’re also releasing the weights for Qwen3.8-Flash-Next, giving the community an early look at the new architecture we’re exploring for Qwen4.🚀 We can't wait to see what you build with Qwen3.8-Flash!👀👇 - Blog: qwen.ai/blog?id=qwen3.… - Technical Report: github.com/QwenLM/Qwen3.8… - Hugging Face: huggingface.co/Qwen/Qwen3.8-F… - ModelScope: modelscope.cn/models/Qwen/Qw…
