> 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

> ⚡️ 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.

> ⚡️ 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.

> Very few people know this, but Muse Spark 1.2 might be the best value model on the market right now.
> 
> Its intelligence is around GPT-5.6 Terra.
> 
> But if you use Muse Code and agree to code analysis through the Contributor tier, the price drops 10–20x.
> 
> So you basically get Terra-level intelligence at Luna-level cost.

> 
> • still $0.75 per 1M input tokens
