   🚨 GLM 5.3 FLASH IS OUT The first natively multimodal model in the GLM 5 series. 320B total parameters, with just 18B active. It beats GLM 5.2 across most benchmarks and gets close to Claude Opus 4.8 on coding and agentic tasks, while costing around 10x less. And yes, ox alpha on OpenRouter and OpenCode was GLM 5.3 Flash.

    ⚡️ Alibaba released Qwen 3.8 Max The new 2.4T parameter flagship benchmarks in the same league as GPT-5.6 Sol, Claude Opus 4.8 and Fable 5. API pricing is $2/M input and $6/M output, roughly half the cost of GPT-5.6 Terra and Claude Sonnet. Now it’s up to users to see whether Qwen can beat DeepSeek-V4-Flash and GPT-5.6 Luna on price to performance.

    Anthropic said it cut 80% of the system prompt for Opus 5 I checked the claim: Opus 4.8: 130K characters Opus 5: 135K characters So the prompt actually got longer. Maybe they meant some specific section inside the system prompt. Or maybe not.

    ⚡️ RELEASE: KIMI K3 Moonshot just dropped its new flagship: 2.8T parameters, a 1M-token context window, native vision, and a focus on large projects, coding, games, and 3D. Full weights are expected in the next few days. API: $3 / $15 per million input/output tokens. Pricing-wise, that puts it around Sonnet 5 or GPT-5.6 Terra, while Moonshot’s own benchmarks have it taking shots at Opus 4.8 and Sol. So basically: Opus-class performance at Sonnet pricing. You can already try it for free on the Kimi website or through Kimi Code CLI.

    Grok 4.5: a new competitor to GPT and Claude Posting this a little late, but I prepared something interesting. Grok 4.5 is temporarily available to test for free in Grok Build and Cursor. The model runs at around 80 tokens per second, supports a context window of up to 500,000 tokens, and costs $2 per million input tokens and $6 per million output tokens. According to Musk, Grok 4.5 was trained from scratch on SpaceXAI’s own foundation and is not built on top of Kimi like Composer. In terms of quality, Grok 4.5 comes close to GPT-5.6 Terra, while its pricing is closer to Luna. Among Anthropic models, it sits between Haiku and Sonnet, making it especially attractive in terms of price-to-pe

    AI completes 16% of the freelance tasks in Remote Labor Index CAIS updated the Remote Labor Index — a benchmark where AI agents complete real client projects: design, video, CAD, architecture, analytics, and web apps. The work is reviewed by humans and compared against a professional deliverable that a paying client would accept. New results: • Claude Fable 5 — 16.1% • Claude Opus 4.8 — 8.3% • GPT-5.5 — 6.3% Fable 5 is now the top model in RLI and almost 2x higher than Opus 4.8. When the benchmark launched, the best result was 2.5%.

    Sonnet 5 looks absurdly priced • Opus 4.8 Max - $1.80 • Sonnet 5 Max - $2.29 • Fable 5 - $2.75 Sonnet 5 is about 27% more expensive than Opus 4.8. Why does the lower-tier model cost more than the flagship?
