Cloudflare's Clef is a 27B Apache-2.0 decision model on Workers AI at $0.24 per million input tokens, and Clef-flash is a 9B model at $0.09 with a 38.8 ms median decision, both Jev-compatible, with an RL fine-tuning service attached.

OpenAI shipped GPT-6.1 Sol on September 29: near-Astra benchmark scores at a fifth of Astra's price, cache reads cut to $0.10 per million tokens, 1.05M context, and same-day Codex availability. The verified pricing, the Astra 6.1 safety hold, the community read, and how to run it.

Claude Code is Anthropic's agent for software engineering; Claude Cowork is the same agent loop pointed at documents, spreadsheets, and research. Both come with every paid Claude plan from $17/month. Here is how to pick, with a verified September 2026 pricing table.

Codex is included in ChatGPT plans from Free to Enterprise. On September 29, 2026, OpenAI reopened Pro $200 with roughly half the old usage value, added Pro $500 with Astra Ultrafast, and left Plus at $20/month. Existing Pro $200 subscribers keep their old allowance through October 29, 2026. Here is how resets work, what each plan buys, and what to do about 'Selected model is at capacity'.

Three frontier launches in 48 hours repriced the agentic workhorse tier: Grok 4.7 at $2/$6 (Sep 21), Claude Opus 5.5 at $4/$20 with $0.20 cache reads (Sep 22), and GPT-6 Sol at $2/$10 with Luna at $0.10/$0.50 (Sep 22). Same-day-verified rates, honest benchmark attribution, and a decision guide.

DeepSeek V4.1 Flash replaced V4 Flash. Official API: $0.15 input, $0.60 output off-peak. OpenRouter hosts start near $0.05. MIT weights are on Hugging Face.

GLM-5.3 routes compared, verified October 1, 2026: OpenRouter hosts list it from $0.12 per million input tokens, GLM-5.3-Flash costs $0.15 input and $0.50 output from Z.ai, batch drops to $0.45/$2.00, and the Coding Plan starts at $18 per month.

DeepSeek V4 Flash routed to Novita on Vercel AI Gateway is 90% off for Pro customers through August 11, dropping the effective rate to $0.014 input / $0.028 output per million tokens. Here is the verified before/after math, the provider-pinning setup, and what a 10x cheap agent loop means for routing decisions.

Cursor shipped a deliberate change on July 31 making the Usage page tokens-only for self-serve plans, removed the dollar Cost column, and zeroed per-request cost fields in the dashboard API - including for historical records. Staff confirmed the change is intentional and that the numbers are still tracked internally.

The cheap coding tier repriced again: GPT-6 Luna opened at $0.10/$0.50 and took the floor from DeepSeek, whose V4.1-Flash cut rates to $0.15/$0.60 off-peak. Gemini 3.5 Flash and Claude Haiku 4.5 hold the hosted middle. Prices verified September 26, 2026.

OpenAI slashes GPT-5.6 Luna by 80% to $0.20/M input tokens, cuts Terra by 20%, adds Sol Fast mode at 2.5x speed, and reveals Sol autonomously optimized its own production kernels.

A practical guide to routing between Claude Opus 5, Sonnet 5, Haiku 4.5, GPT-5.6 Sol/Terra/Luna, and Kimi K3 based on task complexity, cost budget, and latency requirements - with decision frameworks and code examples.

Luna drops from $1/$6 to $0.20/$1.20 per million tokens, Terra from $2.50/$15 to $2/$12, and Sol gets a paid Fast mode. What the new floor means for agent economics, Codex quotas, and the competition.

Where to access Kimi K3: Moonshot's API at $3 input and $15 output per million tokens, OpenRouter hosts, inference clouds, and open weights.

A practical way to price website projects using scope, time, risk, and value, with real examples for landing pages, business sites, and custom builds.

Martin Alderson's argument for why open-weights models like GLM 5.2 will compress frontier lab margins is sparking debate on HN. Here is what the thesis actually says, where HN agrees and disagrees, and why it matters for developers choosing models.

Comparing LLMs by token pricing alone can lead you to choose worse, more expensive models. Cost per task tells the real story.

One expensive orchestrator plus many cheap workers beats an all-frontier fleet for most workloads. Here is the decision-intent cost math with verified Fable 5, Sonnet 5, and Opus 4.8 prices, plus the Sonnet 5 tokenizer caveat that changes worker cost.

Claude is now GA in Microsoft Foundry on Azure with native billing, Entra ID auth, and GB300 Blackwell infrastructure. Here is the full developer setup - CCU pricing, SDK examples, deployment options, and what enterprise teams need to know.

A viral Hacker News thread about AI affordability points at the right problem, but developer teams need a more useful cost model: retries, cache misses, review time, routing, and failed loops.
