What madness is this?

Someone found "Llama3.3-8B" source (never publicly released) in the "wild", then it was adjusted back to 128k and then I added my own special madness:

Training the model with Unsloth (3 epochs) and Claude 4.5-Opus High Reasoning dataset.

This has created an Instruct/Thinking hybrid (128k context, Llama 3.3 model).

Note this tuning was only to create an instruct/thinking model, not to update the model's core knowledge / root training.

Thinking (will activate automatically) prompts - examples:

Explain orbital mechanics including detailed math and examples. (example output at bottom of the page)

Think Deeply: Science Fiction: The Last Transmission - Write a story that takes place entirely within a spaceship's cockpit as the sole surviving crew member attempts to send a final message back to Earth before the ship's power runs out. The story should explore themes of isolation, sacrifice, and the importance of human connection in the face of adversity. If the situation calls for it, have the character(s) curse and swear to further the reader's emotional connection to them. 800-1000 words.

Think deeply: Tell me a horror story.

SETTINGS (suggested):

Temp .7, rep pen 1.05, topp: .95, minp .05, topk: 40

Min context window: 4k, but suggest 8k+.

NO system prompt [thinking tags will self generate].

NOTE:

Temp can range from .1 to 2.5 or higher. Temp will NOT affect "thinking activation" in most cases.

Suggest Quant of Q4KS (non imatrix) or IQ3_M (imatrix) or higher ; lower quants may have reasoning issues/activation issues.

Settings: CHAT / ROLEPLAY and/or SMOOTHER operation of this model:

In "KoboldCpp" or "oobabooga/text-generation-webui" or "Silly Tavern" ;

Set the "Smoothing_factor" to 1.5

: in KoboldCpp -> Settings->Samplers->Advanced-> "Smooth_F"

: in text-generation-webui -> parameters -> lower right.

: In Silly Tavern this is called: "Smoothing"

NOTE: For "text-generation-webui"

-> if using GGUFs you need to use "llama_HF" (which involves downloading some config files from the SOURCE version of this model)

Source versions (and config files) of my models are here:

OTHER OPTIONS:

Increase rep pen to 1.1 to 1.15 (you don't need to do this if you use "smoothing_factor")
If the interface/program you are using to run AI MODELS supports "Quadratic Sampling" ("smoothing") just make the adjustment as noted.

Thought for 19.49 seconds This is a comprehensive request about orbital mechanics. The person wants me to explain the subject in detail, including mathematical derivations and examples. Let me organize this thoroughly. I'll cover: <ol> <li>Fundamentals of Orbital Mechanics</li> <li>Kepler's Laws</li> <li>Elliptical Orbits</li> <li>Orbital Elements</li> <li>Vis-Viva Equation</li> <li>Semi-Analytical Methods</li> <li>Numerical Integration</li> </ol> For each section, I'll include mathematical derivations and examples. <h2 class="western" style="border-top: none; border-bottom: 1px solid #3b3b3b; border-left: none; border-right: none; padding-top: 0cm; padding-bottom: 0.05cm; padding-left: 0cm; padding-right: 0cm"> 1. Fundamentals of Orbital Mechanics</h2> Orbital mechanics deals with the motion of objects in space under gravitational forces. The two-body problem (one object orbiting another) is fundamental. Key quantities: <ul> <li>Semi-major axis (a)</li> <li>Eccentricity (e)</li> <li>Orbital period (T)</li> <li>Gravitational parameter (μ = GM)</li> </ul> <h2 class="western" style="border-top: none; border-bottom: 1px solid #3b3b3b; border-left: none; border-right: none; padding-top: 0cm; padding-bottom: 0.05cm; padding-left: 0cm; padding-right: 0cm"> 2. Kepler's Laws</h2> Kepler's laws provide a framework for understanding orbital motion, derived from Tycho Brahe's observations and Newton's laws. <h3 class="western" style="border: none; padding: 0cm">First Law: Law of Ellipses</h3> An orbit is an ellipse with one focus at the center of mass of the system. <h3 class="western" style="border: none; padding: 0cm">Second Law: Equal Area Rule</h3> The line connecting the planet to the Sun sweeps out equal areas in equal times. <h3 class="western" style="border: none; padding: 0cm">Third Law: Harmonies of the Spheres</h3> There is a universal relationship between orbital period and semi-major axis. Mathematically: T² = (4π²/GM) * a³ Or for Earth around the Sun: T² ≈ 9.95 × 10⁷ * a³ For circular orbits: v²/a = GM/r² = GM/a² = μ/a <h3 class="western" style="border: none; padding: 0cm">Orbital Velocity</h3> The velocity of an object in orbit depends on its distance from the center of gravity. For circular orbits: v = √(GM/r) For elliptical orbits (vis-viva equation): v² = GM(2/r - 1/a) Orbital energy is a fundamental concept in understanding orbital mechanics. The total energy (E) of an orbiting body can be expressed as the sum of kinetic and potential energy components. For circular orbits, the total energy is: E = -GM²/2a This reveals the negative sign indicating gravitational binding energy that keeps the object in continuous orbit around a celestial body. Key orbital parameters include semi-major axis (a), eccentricity (e), inclination (i), longitude of the ascending node (Ω), argument of periapsis (ω), and true anomaly (f). These parameters collectively define the precise orbit of an object in space. For elliptical orbits, the shape is determined by the semi-major axis (a), eccentricity (e), and focal length (c = ae). The semi-major axis represents the average distance between the orbiting body and the center of mass, while eccentricity describes the orbital shape ranging from 0 (circular) to 1 (parabolic). Eccentricity (e) quantifies the deviation from a perfect circle, with values below 1.0 indicating elliptical shapes and 1.0 or higher representing parabolic trajectories. Orbital elements are critical parameters that define an object's orbital characteristics. These include semi-major axis (a), eccentricity (e), inclination (i), longitude of the ascending node (Ω), argument of periapsis (ω), and true anomaly (f). Semi-major axis (a) represents the average distance from the center of mass to the orbiting body, while eccentricity (e) describes the orbital shape. Inclination (i) measures the angle between the orbital plane and a reference plane, typically the ecliptic. Longitude of the ascending node (Ω) identifies the position of the ascending node, marking the point where the object crosses from south to north in its orbit. Argument of periapsis (ω) specifies the position of the closest approach (periapsis) within the orbital plane. True anomaly (f) describes the object's current position along its orbit, ranging from 0° at periapsis to 180° at apoapsis and continuing back to 0° at the next periapsis passage. Vis-viva equation provides a fundamental relationship between orbital velocity, gravitational parameter, and radial distance. This equation reveals how an object's speed changes with distance from its central body, offering insights into orbital mechanics and gravitational interactions. For elliptical orbits, the vis-viva equation extends beyond circular motion by incorporating eccentricity (e) and radial distance (r). The equation shows that velocity remains constant only at specific points (periapsis or apoapsis) in an elliptical trajectory, with varying speeds throughout the orbit. Numerical integration methods offer precise computational approaches for tracking complex orbital trajectories. By discretizing time into smaller intervals and applying numerical techniques, scientists can accurately model orbital dynamics, even when analytical solutions become impractical. Key numerical integration techniques include Runge-Kutta methods, Verlet algorithms, and symplectic integrators. These approaches enable detailed simulations of celestial body interactions, gravitational influences, and orbital perturbations.
