Dataset
GitHub Copilot Model Tracker
Every model GitHub Copilot offers, with its provider, status, GitHub's own task grouping, and any announced retirement date and successor.
Licence and reuse
Free to use and republish, including commercially. Keep the verification date attached to the numbers — a figure from this dataset without its date is not a figure from this dataset.
The underlying facts belong to GitHub and the other vendors documented. What this site contributes is the collection, the verification and the dating — which is also what goes stale, hence the request above.
Methodology
Read from GitHub's supported-models and model-comparison reference pages, and — critically — from the changelog. On 1 September 2026 the reference pages still listed all six models retiring that day with no deprecation notice anywhere on them, so verifying against the reference pages alone would have confirmed a list six models wrong. Task groupings are GitHub's own; a model GitHub places in no group carries an empty grouping here rather than one inferred from its name.

7 models have an announced retirement date
- Claude Opus 4.5 — Sep 1, 2026 · replace with Claude Opus 4.7, Claude Opus 4.8 or Claude Opus 5
- Claude Opus 4.6 — Sep 1, 2026 · replace with Claude Opus 4.7, Claude Opus 4.8 or Claude Opus 5
- Claude Sonnet 4.5 — Sep 1, 2026 · replace with Claude Sonnet 5
- Claude Sonnet 4.6 — Sep 1, 2026 · replace with Claude Sonnet 5 GitHub states Claude Sonnet 4.6 remains available to individual Copilot subscribers on annual plans, so they retain a Sonnet offering; the deprecation does not apply to those customers.
- Gemini 3.1 Pro — Sep 1, 2026 · replace with Gemini 3.6 Flash
- Raptor mini — Sep 1, 2026 · replace with MAI-Code-1-Flash GitHub names MAI-Code-1-Flash as the replacement, and MAI-Code-1-Flash is itself deprecated on 10 September. MAI-Code-1.1-Flash is the destination that survives both dates.
- MAI-Code-1-Flash — Sep 10, 2026 · replace with MAI-Code-1.1-Flash Also the named successor for Raptor mini, which is deprecated on 1 September — nine days before this model is. Anyone following that migration path should go straight to MAI-Code-1.1-Flash.
Seven providers. The concentration matters less than the retirement column: every provider with more than one model has at least one on the way out.

Reading this table
"Not placed" is not a judgement. GitHub's comparison page names five models under general-purpose coding and three under fast work, out of 32. A model absent from every grouping has not been assessed as unsuitable — GitHub simply has not placed it, and inferring a placement from the model's name would be our opinion wearing GitHub's label.
Providers represented: OpenAI, Anthropic, Google, Microsoft, Fine-tuned GPT-5 mini, Moonshot AI, xAI.
Deeper context on what actually differs between these models is in the models lesson, and how to choose one covers the decision rather than the inventory.
The retirement dates in this table are the reason for our measurement of documentation drift on retirement day — GitHub's own docs and changelog disagreed about which models were still available, which is why this dataset records a verification date rather than a publication date.
Using this dataset
Both endpoints are static, cached and served with Access-Control-Allow-Origin: *, so they can be fetched directly from a browser or a build script. Neither requires a key.
JSON
curl -s https://thecopilotstack.com/data/copilot-models.json | jq '.models[0]'The response is an envelope, not a bare array. Every dataset on this site carries dataset, canonical, verifiedDate, reviewIntervalDays, methodology, sources and licence, with the rows under models; this one adds its own descriptive keys alongside them. A copy of the file is therefore self-describing — which is the point, because a bare array is indistinguishable from a stale one the moment it leaves this domain.
CSV
curl -s -o copilot-data.csv https://thecopilotstack.com/data/copilot-models.csvOne header row, one row per model. The CSV carries no envelope, so record alongside it yourself.
Change history
9 recorded changes. Each was read from a primary source on the date shown; nothing is reconstructed or backfilled. The history begins when this site started checking, not when the product did.

Deprecated. Replacement named: Gemini 3.6 Flash.
Gemini 3.1 Pro was simultaneously one of only three models GitHub listed under visual work and one of six under deep reasoning — the comparison page was recommending it on the day it was retired.

The named successor is itself deprecated nine days later. Following the migration literally means moving twice; MAI-Code-1.1-Flash is the destination that survives both dates.

- ChangedTask groupings
Task groupings realigned to exactly the models GitHub places in each group.
This dataset previously assigned every Opus release to deep reasoning and every Flash release to fast work by inference. GitHub names five models under general-purpose and three under fast; 20 of 32 models sit in no group at all. A model GitHub does not place now carries an empty grouping rather than one this site inferred.

Cite this dataset
Free to use, republish and build on. A link back is appreciated and is not a condition. The one thing we ask is that theverification date travels with the numbers — several of these figures change monthly, and a table with no date on it becomes misinformation within a quarter however accurate it was when copied.
