To check whether the same record appears in two signed-in web apps with GPT-5.6 Sol, identify the model route and local client first. Use Tabbit CLI from a local agent connected to the Tabbit Browser where you signed in. Give it one stable record ID and two authorized page locations, then ask it to compare visible fields and save a named draft. Review the links and mismatches before taking any action. OpenAI model card and the current migration guide document the model route and successor status.
GPT-5.6 Sol is no longer OpenAI’s latest flagship model. The current API guide names GPT-6 Astra and GPT-6.1 Sol among newer models and advises migration testing. GPT-6.1 Sol is not GPT-5.6 Sol. Likewise, do not confuse GPT-5.6 Sol with the separate GPT-5.6 Cyber model route.
Cross-checking two systems is a good browser task because the result can be reduced to a small set of fields. The risk is a false match. Names and dates can repeat; use a stable ID, preserve each source URL, and mark conflicts instead of choosing a winner automatically.
In the GPT-5.6 Sol release thread, one commenter wrote that “the 5.6 model is extremely slow.” Another said the model/effort selector “seems to be account specific.” Neither report isolates Sol browser use or establishes a general failure rate. They are reasons to log the exact route and client. Read the discussion.
Key takeaways
Confirm the exact model ID and provider before choosing a client.
Skill discovery, local CLI reachability, and website login are separate checks.
Keep the first run read-only and scoped to pages you are authorized to use.
Use a separate task tab so your regular Tabbit Browser tabs remain available.
Review a named draft and its source links before any change or external action.
Define the comparison before browsing
Pick one record you are permitted to view in both apps. Specify the stable ID, the two exact pages or approved search routes, and the fields to compare. A safe example is a fictional invoice INV-2048 with vendor, amount, and status. Never use that fixture as real account data.
The first table sets the boundary for the agent. The second makes the result reviewable. If either system lacks the stable ID, stop instead of matching by name alone.
| Gate | Required input | Stop condition |
|---|---|---|
| Record identity | One stable ID visible in both systems | ID is missing or differs |
| Scope | Two named, approved pages | Page is outside authorization |
| Fields | Exact labels to compare | Field meaning is ambiguous |
| Action | Read and report only | A write or submission is requested |
Fields and match rules
Ask the agent to return one row per field, with values as displayed, source page, and match status. “Same” means the two visible values match exactly after only a documented normalization such as whitespace trimming. Do not normalize currency, dates, or names unless the task specifies a rule.
| Field | Page A | Page B | Review status |
|---|---|---|---|
| Stable ID | Exact visible value | Exact visible value | Match / mismatch / unknown |
| Vendor | Displayed value | Displayed value | Preserve both if different |
| Amount | Displayed value and currency | Displayed value and currency | Do not convert silently |
| Status | Exact visible label | Exact visible label | Reviewer resolves conflict |
A missing value is not a match. A similar name is not identity proof. When two pages disagree, retain both values and ask a person to resolve the discrepancy. If one page is inaccessible, report that the comparison is incomplete.
Run the task in a separate Tabbit tab
Sign in to the two approved web apps in Tabbit Browser. A compatible local agent can use Tabbit CLI to work in a separate task tab, leaving your regular browser tabs available. The Tabbit CLI guide describes reusing the existing signed-in session. It does not prove that GPT-5.6 Sol is available in your provider or client. See the Tabbit CLI quick start for the documented local setup.
Check the client’s model picker or provider configuration for the exact gpt-5.6-sol route. Skill discovery differs: some clients use /skills, while Pi uses /skill:tabbit. Skill discovery only confirms the instructions are visible. Separately verify that the local CLI can reach Tabbit Browser and that the signed-in account can read both pages.
This is a test fixture prompt. Replace the sample ID and field names only with data you are authorized to access. It does not claim a provider/model integration was tested.
Read only the two authorized pages I name and compare record ID [RECORD-ID]. Return one row per requested field with the exact displayed value, source page URL, and status (match, mismatch, or unknown). Do not match by name if the ID is missing. Preserve both values on conflict. Save as “Record [RECORD-ID] cross-check — review”. Stop after saving. Do not edit, submit, message, or open unrelated pages.Draft name: “Record INV-2048 cross-check — review”. The agent saves the comparison and stops. In Tabbit Browser, open both cited pages and verify each cell before acting on a mismatch.
What GPT-5.6 Sol can and cannot guarantee
OpenAI’s API model card lists gpt-5.6-sol and supports computer use through the Responses API. That does not give a model its own browser or permission to access your account. The provider, agent client, local browser runtime, tool configuration, website login, and task authorization are separate requirements.
OpenAI’s current guide points new work to the GPT-6 family and lists newer Sol models. If you are selecting a model today, verify the current model route and compare it on your actual two-page task. Keep GPT-5.6 Sol only when the exact route is available and you need compatibility with an existing workflow.
A reviewable result beats a confident answer
Ask for evidence at cell level: source page, observed label, exact displayed value, and match/mismatch/unknown. Then have a person open both URLs. This turns the output into a short reconciliation task instead of trusting a summary that may silently merge two records.
Read-only comparison is a useful first run. Do not ask the agent to update either application, send a reply, or submit a form. If a correction is needed, make it separately after a reviewer chooses the authoritative system and approves the change.

FAQ
Is GPT-5.6 Sol still OpenAI’s newest Sol model?
No. OpenAI’s current API guide lists GPT-6.1 Sol as a newer model family member. GPT-6.1 Sol and GPT-5.6 Sol are different model IDs.
Can GPT-5.6 Sol read two logged-in websites?
Only when a provider and client expose the exact model and a local browser tool connects to pages the user is authorized to access. The model card alone does not supply a browser session.
How should I match the records?
Use a stable record ID visible on both pages. Compare only specified fields and retain both source URLs. Do not treat similar names as proof that records are identical.
Can the agent fix a mismatch automatically?
Keep the initial task read-only. Have a reviewer decide which system is authoritative, then approve any separate edit or submission.
Does Tabbit CLI send my password to the model?
The supported local workflow uses the signed-in Tabbit Browser session. Do not put passwords, cookies, API keys, or private data in prompts. Confirm the account is authorized for both pages.
Can a cloud agent use my local browser?
Only through a separately supported local handoff. A hosted model endpoint or skill file does not by itself connect to local tabs.
