  1. Hand-drawn ink illustration: three different objects in a row, each delivering water into the same glass. A plumbed-in public drinking fountain on the left; a hand-built rig of copper pipe, valves and a pump on a wooden crate in the middle, its workings exposed with a toolbox beside it; a sealed brass cabinet on the right whose side hatch is open while a hand fits a yellow cartridge into it.

  2. Hand-drawn ink illustration: a wooden counter with a person on each side and five objects along it, each caught at a different point of being handed over — a ring of yellow keys still held on the near side, a folded contract half-slid across with a corner in each hand, a sealed conduit resting exactly on the centre line, a brass alarm bell already on the far side, and a toolbox under the far person's hand.

  3. Hand-drawn ink illustration on warm paper: four brass mail-sorting chutes above one shared tray. Three drop their letters into their tray slots; the fourth diverts its letter out of a small side hatch, leaving its tray slot empty. A single small yellow flag stands on the machine.

  4. Dumbbell chart of bartowski's Nemotron-3.5-Lightning GGUF files: bits per weight the filename claims against bits per weight measured from the tensor table, every k- and i-quant rung landing at or above a 4.5 bpw floor

    Why your IQ2 GGUF is the same size as IQ4: the 256-block fallback in llama-quantize

  5. Matrix of GLM-5.3's sixteen OpenRouter endpoints on 2026-08-29 05:24 UTC, grouped by self-declared quantization: bf16 one host at $1.20/$4.00, fp8 seven hosts at $1.25–1.40 in, fp4 two hosts at $1.40/$4.40, unknown six hosts at $1.40/$4.40

    GLM-5.3 open weights, day one: 16 providers, five prices, four quantizations — and BF16 is the cheapest

  6. Timeline of the SpaceX–Cursor deal and OpenAI's response: 21 April option announced, 14 August acquisition completed, 28 August notice given, 12 November proposed shutoff

    Cursor loses OpenAI models on November 12: the change-of-control clause behind the date, and the five questions to ask whoever holds your key

  7. Matrix of seven protocol dimensions across OpenAI Chat Completions, Anthropic Messages and Gemini generateContent, with the field name each vendor uses

    One API for OpenAI, Anthropic and Google models: what translates, and the seven things that leak through

  8. Four-stage diagram for Kimi K3: 2.8T weights free to download → host needs 8× GB300 or more → reported revenue share of up to 30% → token auditing unresolved. Below it, the three license thresholds: $20M over 12 months, 100M MAU or $20M a month, internal use and certified partners exempt

    Kimi K3 license, commercial use: the $20M MaaS clause, the 100M-MAU badge, and the 30% Moonshot wants from Azure, AWS and Google

  9. Matrix of six LLM API products offered as OpenRouter alternatives — Cloudflare AI Gateway, AWS Bedrock, Google Vertex, Groq, LiteLLM and Portkey — against four production columns: cross-vendor failover, a spend cap below the account, the Anthropic Messages API, and a zero-data-retention control, each cell marked available, gated or absent according to the vendor's own documentation

    OpenRouter alternatives for production workloads: what Cloudflare, Bedrock, Vertex, Groq, LiteLLM and Portkey actually document

  10. Hand-drawn illustration: an open-air bazaar of model makers' stalls; at the gate a brass shovel-maker's cart has parked while a porter ties a single yellow reservation ribbon to the gatepost

  11. Hand-drawn illustration: one open team wallet on a wooden workbench with five hands reaching in at once, a single yellow coin among grey tokens, and a brass padlock hanging unlatched from the clasp

    Shared team wallet for LLM APIs: who actually has one, and what each cap misses

  12. Matrix of failover trigger conditions across seven LLM gateways: 5xx, timeouts and 429 are covered everywhere, by default or opt-in; 404 is opt-in or unstated in most; the row for a 200 whose provider state changed is empty in every column, with Portkey's guardrail path as the one partial exception noted in the text

    Automatic failover in LiteLLM, Portkey and OpenRouter: what actually triggers it, and the 429 no gateway tracks
