## 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

## Semafind

Semafind works with organisations that face problems too specific to be solved by off-the-shelf software. The firm positions itself between academic research and applied engineering: it helps clients explore whether a novel algorithm or model can create a competitive edge, builds a working prototype, then integrates that technology into existing infrastructure with training and ongoing support. Its stated process runs through ideation, prototyping and integration, each stage aimed at reducing the risk of research-heavy projects.

The consultancy publishes a portfolio of applied projects that show the range of work it takes on, including a visual spare-part identification system for engineering maintenance, semantic CV matching that recommends roles from resumes and job descriptions, AI networking recommendations for events, behavioural anomaly detection for early disease identification in animals, a reverse dictionary for company terminology, and personalised e-commerce product recommendations.

Semafind also productises some of this research. SemaReader focuses on semantic reading and automatic knowledge-graph creation from documents, while SemaDB is its vector database offering for similarity search. Knotes is an additional knowledge tool. The company is a UK-registered limited company and invites prospective clients to a free initial consultation. Because engagements are scoped per project, pricing is quoted on contact rather than published as fixed public tiers.

**Pricing & Plans:** Pricing is quote-based: Semafind offers a free initial consultation and scopes consulting engagements per project. Its software products such as SemaReader and SemaDB have their own plans — check the official site for current figures.

- **Custom AI & ML engineering:** Bespoke algorithms and models built for problems that generic tools cannot solve, from computer vision to recommendation systems.
- **Research-to-production pipeline:** A structured ideation, prototype and integration process designed to de-risk research-heavy projects before full rollout.
- **Semantic knowledge tooling:** Products including SemaReader for semantic reading and knowledge-graph creation, and SemaDB, a vector database for similarity search.
- **Data science consulting:** Hands-on data analysis, anomaly detection and predictive modelling engagements shaped around specific business goals.
- **Training and ongoing support:** Integration includes team training and continued support so new technology is adopted rather than shelved.

**Strengths:** Genuine research depth rather than template implementation; Clearly documented portfolio of applied projects across industries; Combines consulting with owned products such as SemaReader and SemaDB; Free initial consultation lowers the barrier to starting a conversation

**Limitations:** No published price list, so budgeting requires a sales conversation; Project-based engagements may not suit very small, low-budget teams; Product documentation for SemaReader and SemaDB is comparatively light
