## 14DaysOfAI (100 School)

14DaysOfAI (now also presented as "15 Days of AI") is an email-based learning challenge run by 100 School. Instead of long video courses, it sends one compact lesson to your inbox every weekday morning, sized for roughly 15 minutes of focused practice. The curriculum is split into three arcs: thinking with AI, building with AI, and working with AI, so learners move from first principles to hands-on automation and prototyping.

The challenge is aimed at professionals rather than developers. Lessons mix explanation with concrete tasks, so you finish with working prompts, small workflows and an automation habit instead of just theory. 100 School also offers a teams track for organisations that want structured AI upskilling with accountability, and runs a newsletter plus additional courses on no-code and writing.

Because it is delivered by email, the format adapts well to busy schedules: there is no fixed class time, and you keep the lesson archive to revisit later. It is free to join the individual challenge.

**Pricing & Plans:** The individual challenge is free to join. 100 School sells a separate paid offering for teams; specific pricing is quoted on request.

- **Daily email lessons:** A new lesson lands in your inbox each weekday morning, designed to be completed in about 15 minutes.
- **Three-week skill arc:** Progresses from how AI models work, to building prompts and automations, to embedding AI into your daily workflow.
- **Task-based practice:** Lessons pair each concept with a real work task so you produce usable outputs, not just notes.
- **No setup required:** Everything runs through your existing email and whatever AI tools you already use; no installs or coding environment.
- **Teams programme:** A structured version for organisations that adds accountability and group capability building.

**Strengths:** Very low time commitment, roughly 15 minutes per weekday; Free to join the individual challenge; Practical, task-oriented curriculum rather than passive video; Delivered by email, so it fits any schedule and works on any device

**Limitations:** The daily drip format means you cannot binge the whole curriculum at once; Best results depend on actually doing the tasks, which takes discipline; Content is generalist, so specialists may want deeper technical material

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
