This week picks: Cursor Pro for daily coding ($20/mo + 17% off annual), DeepSeek V4.1 Flash for batch workloads (¥1/M valley), tokenrhythm aggregator for peak production (¥500 credit + multi-model arbitrage). [更早的版本说明已归档至 /changelog，本条目仅保留最近 3 期更新锚点] 【2026-10-14 Wednesday W42 Update】 Coding Plan vs Token Plan vs API Aggregator: (1) **Coding Plan** (Cursor Pro $16/月 + GLM Coding Max ¥120/月 + Kimi Code Andante ¥49/月) = IDE 集成绑定 monthly quota. (2) **Token Plan** (Aliyun Bailian Lite ¥39/月含 700 Credits/5h + Standard ¥139 + Pro ¥499) = Credits 跨模型计费 + 多 Agent 并发. (3) **API Aggregator** (TokenRhythm 1M ¥1/¥1 per M + ¥500 credit to 10/31) = 跨厂商 5 款 1M 模型统一入口. Best combo under $80/月 = Cursor Pro $16 + GLM Coding Max ¥120 + TokenRhythm 1M ¥200 + Kimi Code Andante ¥49 ≈ ¥505/月 = $70. Top picks by scenario: heavy IDE user → Coding Plan; multi-model Agent workflow → Token Plan; cost-sensitive cross-vendor → API Aggregator. [W43 Wednesday update · 2026-10-21] Coding Plan vs Token Plan vs API aggregator — pick the subscription shape that fits this scenario: (1) under 500 IDE requests/day on a fixed workflow → Coding Plan is cheapest (GLM Coding Pro ¥80/mo with 2000 GLM-5.3-Flash + 50 Sonnet 5 calls; after Cursor's 10/21 rebuild the entry paid tier is Plus $8/mo and Premium $30/mo is the 4x tier flagged most popular); (2) stable single-vendor long-context work → Token Plan is cheapest (Alibaba Bailian Standard ¥39/mo with unlimited Qwen3.8-Flash at 1M context, ¥27.3 first month; Tencent Hy3 ¥150/mo or ¥1100/yr); (3) cross-vendor batch, agent orchestration, or anything that should run in valley hours → API aggregator is cheapest (TokenRhythm ¥1/¥1 per M with a ¥500 trial credit extended to 10/31; DeepSeek valley/peak verified 10/21 — peak is only Mon-Fri 01:00-04:00 and 06:00-10:00 UTC, so off-peak V4-Pro output is $1.98 vs $3.96 peak). The best W43 value uses all three at once: one Coding Plan for the IDE, one Token Plan for long documents, one aggregator account for batch and valley-hour runs. Two normalization caveats: Claude 4.7+ uses a new tokenizer producing ~30% more tokens for the same text, and MiniMax M3 doubles in cost once input crosses 512K tokens (¥2.1/¥8.4 → ¥4.2/¥16.8). Updated October 22, 2026 (W43 Thursday) — biggest vendor price moves this week: DeepSeek Search/Fetch APIs switch to per-request billing at $0.75 per 1,000 successful calls starting November 1, 2026 (previously free through DeepSeek Harness, Claude Code, and Codex server-side tool calls); Anthropic cancelled the Claude Sonnet 5 increase scheduled for September 1, making $2/$10 the permanent standard price; Claude Haiku 5.5 launched at $0.10/$0.50 for prompts up to 100K, a 90% input-price cut versus Haiku 4.5; OpenAI locked GPT-5.6 Sol at $4/$20 as promotional pricing available at least through November 21, with Batch and Flex at $2/$10 and a doubling to $8/$30 above 272K input tokens; MiniMax launched M3.1-Flash at ¥1/¥4 and made M3's 50% discount permanent below 512K input; Zhipu's GLM-5.3-Flash is at a limited-time ¥0.40/¥1.40; xAI's Grok 4.7 matches 4.6 at $2/$6 but raised cache reads from $0.30 to $0.50. Note that Claude 4.7+ uses a tokenizer producing roughly 30% more tokens for the same text. [W43 Friday update · 2026-10-23] Free and discounted APIs of the week. OpenAI Decisions API went GA at $0.10 per 1M input tokens with $0.01 cached input and **no output charge**, up to 400 questions per request and up to 10x faster than GPT-6 Luna through the Responses API — the cheapest option for batch ranking, triage and classification because the output side is free. iFlytek Spark X2.6 launched at CNY 0.9 / 0.08 cached / 3.6 output per 1M with a 1M context window and an open-sourced 4B distilled build. xAI grok-4.3 is $1.25/$2.50 with 1M context, 37% cheaper than Grok 4.7 which caps at 500K. Anthropic now documents free tool tiers: Web Fetch is free, Code Execution includes 1,550 free container hours per organization per month, Web Search is $10 per 1,000 successful searches, and Claude Managed Agents cost $0.08 per session-hour charged only while running. Zhipu's GLM-5.3-Flash limited-time 50% discount at CNY 0.40/1.40 expires October 28; MiniMax made M3's 50% discount below 512K permanent at CNY 2.10/8.40 and launched M3.1-Flash at CNY 1.00/4.00.
