## Mixl (LZR Focus)

LZR Focus, distributed under the Chrome Web Store listing formerly named Mixl, is a browser-sidebar productivity tool built around a simple idea: most people drift not because they lack willpower but because they never turned an intention into a concrete task with a time box. Opening the sidebar starts a short conversation with an AI coach that helps you phrase a SMART goal, then turns that goal into a timed focus session of between five and 120 minutes.

The music angle is what distinguishes it from a plain Pomodoro timer. Focus music is generated by AI and played directly from the sidebar, with saved tracks looping in sequence and fresh tracks generated when the playlist empties. For people who find silence distracting or who fall down rabbit holes searching for the right playlist, this keeps everything in the same pane as the task.

The third pillar is an optional Focus Score. With your permission, it sends the active tab's title and domain plus your session goal to an AI service and returns a relevance estimate. The extension explicitly frames this as tab relevance rather than a measure of attention or output, and the developer's disclosure says data is not sold or used outside core functionality. Session recaps and a brief celebration close the loop, and the AI coach can be sampled as a guest before you sign in.

**Pricing & Plans:** Free to install and use with the AI coach available as a guest; continued coaching requires sign-in and the Chrome Web Store lists the extension as free with a Freemium-style model. No published paid tiers were visible on the listing.

- **AI goal coach for SMART goals:** Describe a vague intention and the coach helps turn it into a Specific, Measurable, Achievable, Relevant and Time-bound goal you can review and edit before starting.
- **Flexible 5-120 minute focus timer:** Pick a session length anywhere from 5 to 120 minutes and watch a calm countdown in the sidebar without leaving your work for another dashboard.
- **AI focus music playlists:** Optional AI-generated focus music plays from the sidebar, and new tracks are generated when the playlist runs out.
- **Optional Focus Score:** An optional Focus Score estimates how closely your open tabs relate to your goal, using only tab title and domain, with tab checks running only during active sessions.
- **Session recap and streaks:** Each session ends with a recap and a brief celebration, and you can immediately queue up another session.

**Strengths:** Turns vague intentions into an editable SMART goal before starting; Focus music generated in-app, so no playlist hunting; Focus Score is genuinely optional and disclosed in detail; Session recap plus optional celebration adds a light accountability loop

**Limitations:** Requires an internet connection and sign-in for continued AI coaching; Optional Focus Score shares active tab title/domain with an AI service; Music generation is limited to focus-session playlists rather than full music production; Only available as a Chrome sidebar extension, not standalone apps

## 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
