The information you read regarding the performance and the API pricing of Qwen3.8-Max is accurate, but the reason you did not need to pay on chat.qwen.ai is because Alibaba separates its products into two different tiers: the Developer API and the Consumer Web Interface.

1. The Benchmarks You Read Are Real Qwen3.8-Max is Alibaba’s flagship 2.4-trillion-parameter multimodal model released in mid-2026 [[5]]. The scores you mentioned are correct, as it indeed rivals Anthropic’s Fable 5 by scoring 93.0 on PaperBench, 74.8 on CoWorkBench, and 81.9 on WideSearch [[18]].

2. Why the API Has a Price Tag The pricing you saw applies specifically to the Alibaba Cloud API tier where commercial users are charged for input and output tokens [[25]]. This pay-as-you-go pricing is meant for developers and enterprises who want to build their own applications or integrate the model into commercial software via the API [[22]]. Because these users are pulling compute resources programmatically at scale, they are charged based on exact token consumption.

3. Why chat.qwen.ai is Free chat.qwen.ai (also branded as Qwen Studio) is Alibaba’s official consumer-facing chat platform designed for everyday users [[24]]. Rather than charging individual users per token, Alibaba provides this web interface for free to let the general public experience their latest models and build a broad user base [[23]]. The company essentially subsidizes the compute cost for individual web chats.

This is a standard business model in the AI industry. It is very similar to how you can chat with other AI models for free on their official websites, while software companies must pay for the expensive API tokens to power third-party apps and coding agents behind the scenes.

1. Proteins (The actual efflux pumps)

• Rule: Capitalized, NOT italicized.
• Examples: AdeABC, AdeIJK, CraA, AdeA, AdeB.
• Usage in your text: “Chloramphenicol was selected because previous studies have established AdeABC, AdeIJK, and CraA as the principal determinants of chloramphenicol resistance…” (Correct!)

2. Genes (The DNA sequences)

• Rule: Lowercase, italicized.
• Examples: adeABC, adeIJK, craA, adeA.
• Usage in your text: *”Expression of adeABC and adeIJK is controlled by transcriptional regulators…” or “The craA gene was upregulated…”*

3. Mutants / Deletions

• Rule: The Greek letter delta (Δ) is non-italicized, followed by the lowercase, italicized gene name.
• Examples: ΔadeAB, ΔadeIJ, ΔcraA.
• Usage in your text: *”Isogenic ΔadeAB and ΔadeIJ mutants were constructed…”*

Summary Checklist for your manuscript:

• If you are talking about the physical pump / protein complex $\rightarrow$ AdeABC, AdeIJK, CraA (No italics, capitalized)
• If you are talking about the DNA / gene / transcription $\rightarrow$ adeABC, adeIJK, craA (Italics, lowercase)
• If you are talking about the knockout strain $\rightarrow$ ΔadeAB, ΔadeIJ, ΔcraA (Delta non-italic, gene italicized & lowercase)

So, in the sentence you are asking about, leaving AdeABC, AdeIJK, and CraA as non-italicized is exactly correct!
